View Full Version : AE - LW Camera Tracking 11.5

Very excited to start using AE camera tracking to import into LW. But getting terrible slipping inside LW.

The camera track is rock solid (please see AE screen capture - text is planted firmly on the couch).

But bringing in the null (parented to the text) and camera into LW, there's slipping all over. I created a ground plane and parented it to the same null object generated from AE.

I attached camera settings from both AE and LW, but can't figure out the cause of the slippage.

Anyone know how to make this a rock solid connection?

Thanks in advance.

PS: that's my dog Amordios.

Hmmm, I'm too having a problem matching the AE Camera with 3d space, tracking looks good in AE, created a 3D text, and since I was tracking a table in a living room, it was fairly easy and clean track, however the camera movement in LW are not looking properly, besides it's quite annoying that AE pixel scale...

Dillon

Thanks for your response, 50one. I wonder if its a time code issue (drop frame v. non drop?) or pixel dimension? Supposedly the AE/LW connection is supposed to be pixel perfect. But that is clearly not the case.

Hope someone can help us resolve this. I'm working on another project so I can't dedicate myself to solving it, but I am determined to find a perfect workflow. There is just too much power between AE and LW between camera tracking and 3D space / VFX.

So I understand, you tracked this footage in AE then sent the motion data to LW, correct?

I don't have LW in front of me to check, but does it matter if your camera settings are different?

Dillon
02-01-2013, 03:11 PM
Yes.

Tracked in AE, and then exported camera and null to LW. The camera is created in LW by the camera settings in AE (matches dimension, frame rate, aspect ratio, etc).

And of course it would matter if the camera settings are different, but from all appearances, the camera settings are the same.

Hmm. You just made me think of something. I wonder if changing the camera type inside LW might affect it. Since there are different kinds of cameras ....

To me, it looks like the keyframes don't have the same kind of 'incoming curve' settings, or they do and the math is different.

In LW, make the tension in the curve 1 and what does that look like?

Lots more to learn...

Dillon
02-01-2013, 03:34 PM
Hmm, there's a thought.

The way AE exports the camera data is to have a keyframe at every frame.

Changed the tension on every keyframe to 1. no difference.

Went and took a look at the keyframe interpolation in AE - temporal is linear, spatial is auto bezier. So I changed the keyframe interpolation in the graph editor in LW to linear. That changes the slipperiness a little bit, but no improvement. Still slippery like a sliding around on a smeared banana slug on recently waxed ice.


Thanks for the suggestion!

29.97. Set under General Options / preferences. Frame rate is 29.97. Same as in AE.

Also, I can't find where to toggle drop/non drop time code in layout either.

I feel like a rookie again!

Are both LightWave and AE set to same start frame, i.e both 0 to whatever or 1 to whatever?

Darth Mole
02-01-2013, 05:27 PM
What he said. Every time I get slippage with a camera track it's because my track starts on frame 1 and LW starts on frame 0 (or vice versa). Not tried the AE connection yet, but that could be a possible culprit.

Dillon
02-01-2013, 06:07 PM
Hmmm, now that you mention it, I recall this being a problem before. I'll play around with these settings more (Just spent the last 5 minutes, but still finding slipping).

And yes, AE timeline starts at 0, and LW starts at default 1. Changed LW to start at 0, still go slipping. Then changed the movie start in image editor to start at 1. Still slipping.

Thanks for the input!

Hmm, on inspecting the scene elements (null placements), it seems the scale of the scene in LW is entirely off from the scale generated by AE. I don't see a place to set scene scale in the AE camera tracker.

Drrrr.

I believe it may use "pixel" units.

i.e. 100 pixels= 100 LW units (whatever those are that you decide, mm, ft, M....) etc ????

I'm confused and amazed to read people have this working. Very little happens for me.

Following the few directions in the help, I hit the SEND TO AE button in LW, AE opens and closes immediately. If I have AE open already nothing happens. If I select my camera in AE and export that to LW, nothing happens.

I do have my camera object selected in LW before I try to send. I've updated the path to layout.exe in AE. I've copied the plugin from LW to AE folder. I've checked the box in AE for external scripts. I've saved the scene in LW.

I'm using AE CS6 on Win 7 x64. Anyone experiencing the same?

From the manual:
In Layout the AE link is on the I/O tab in Layout where there are two buttons. .. says the Department of Redundancy Department. :)

are you doing a 3D track or standard 2D track via AE ? otherwise you will always get slippage there is not enough track data to give solid calculations its not a didicated app regarding tracking it essentially fakes it ...even in the the feature video you can see the logo giving some movement however you can trick it goto videocopliot and view the demon face that gives solid results

when you add a new camera to the scene in AE it will give you what the scale is in ... mm , pixels or inches is the options, it that is what you mean?

Well after extensive testing and tweaking, I can only assume that LW doesn't quite read the scene scale that AE is "faking" from its camera tracker. Which is sad; I was really looking forward to using AE's camera tracker.

With the shot I posted at the beginning of this thread (it's a hand held dolly shot), I am able to place text and nulls and adjustment layers to my hearts content with absolute lock (no slipping). Unable to get the scene to stop sliding around in LW.

Looks like I might need to buy Syntheyes after all. *sigh*

Thanks for all your input to the thread guys. Much appreciated!

That would be odd, since the ae tracker generates coordinates in AE just like all other 3d components in AE which should translate fine..

Do you have a AE project to go with the mov file that has tracked nulls/text you can share?

Dillon
02-02-2013, 12:02 PM
Sure; here's the .zip with AE, LW and .mov files. On inspecting the perspective views both in AE and in LW, it seems the camera relationship to the 3 nulls does indeed match. Though I don't agree with the axis alignment of the 'scene' in relationship to the camera. Too bad the AE tracker can't designate scene orientation and scale. As others commented, AE's tracker isn't a pro solution, and I should not have expected it to be one.

Hope you have better luck than me!

Hi Just wondering if you hit the settings button in light wave which path for ae is it set to? It works here no problem with ae cs5.5 on windows 7 64 bit. It should open ae if it's not all ready open. Have you tried ae cs5.5 to see if that is the problem?

Did you copy the plugin in the plugins folder of ae? Because you said the ae folder. If so you should see export data to lightwave under the export tab if the plugin to is installed right

Hey Dillon

I downloaded your archive.zip file and did some tests regarding the Send to AE

I managed to get a solid track and the export out of AE to ligtwave was great. No slipping or sliding

Here is what I did

1. I tracked the footage in Syntheyes not AE CS6 since I don't have it yet
2. I set up the coordinates system so it matched the same orientation as the shot. ( I noticed your coordinates system (Grid) was not matching the video. Did you set up your coordinates system in your tracking software
3. I exported the tracking data out of Syntheyes directly into AE using the export to .ma scene
4. I imported the .ma file into AE, this gave me a AE camera and all sorts of nulls
5. I selected the camera in AE and used the export to lightwave script.

The camera came into Lightwave with no problems. The Grid matched the orientation of the shot and everything stayed as rock solid as you can expect trying to track from a compressed quicktime video.

Some of the things I noticed from your video that could of caused the probelem are

- Not sure but maybe AE CS6 tracking is causing the problem, sorry don't have AECS6 yet to test
- Try putting in the coordinates system so it matches your video (Grid runs along the floor)
- I noticed you had tracking marks on the dogs ears which move around. When I tracked the footage I deleted those tracking marks so I could get as clean a track as possible.

Here is my lightwave, syntheyes scenes also the exported .ma file

"I noticed you had tracking marks on the dogs ears" jboudreau

As per this, I also use both syntheyes and AE, as well as Mocha Pro for tracking. Tracking is not a button(s) it's a technique. The business of tracking the dog ears tells me that you should probably brush up on the principles behind tracking.

I don't say this to insult, I say it because I used to get all sorts of trashy tracking results in all the programs. After doing some books, websites and tutorials I get much better results. The principles are really important to getting good to great results.

Resources: Russ Andersson (Author of Syntheyes) has some excellent tutorials, you tube, CMIfx, "Matchmoving The invisible art of tracking" by Tim Dobbert. etc....

This is the path my AE: C:/Program Files/Adobe/Adobe After Effects CS6/Support Files/AfterFX.exe

It was already set when I checked and I verified it's correct.

I did copy the file to the /plugins folder. Is that where it needs to be? It's not in a subfolder, just the root of plugins.

Have the same problem you do sadkkf...

Also, I tried exporting the camera from AE to LW and got a script error "no valid path specified."

So, do I have to create/save, whatever, a LW scene for it to become bidirectional? Has anyone had success exporting from AE to LW first?

I've had trouble exporting 3d data of tracked footage from AE in the past, it seems to be very footage dependant. In AE, if you're finding scale an issue just create a null, make it 3d, parent EVERYTHING to it (including camera) and scale/rotate/move that null accordingly.

Dillon

Hey Jason,

Thanks for doing all that. A couple things in response to your input;

1. I don't have Synth Eyes. I'm hoping to get the solid stable track that is in AE into LW without Synth Eyes.
2. Yeah, I rebuilt the scene to compress (with smaller .mov file) and forgot to get rid of the markers on my dog before creating the 3D camera. I've worked with 3D trackers before (including Synth Eyes) and know that markers on moving objects make for bad tracks without a lot of user input.
3. AE camera tracker doesn't have any input for a user to define orientation or scale of the scene.

Thanks again!

Hey, Kevin. Thanks for your input, too. See my response to jboudreau (I'm aware of the process, and forgot to remove the markers on my dog before sending the file).

Even with the markers removed from my dog and a 3D camera generated, the scenes don't match up between AE and LW.

Dillon

What do you mean "the calculations points where bigger than the video you originally posted"..? Did you track different footage? You resized the tracker markers to be much larger?

If there's sliding, still, it makes it unusable to make anything believable, though.

Hi Guys

I'm not sure why you are having such a problem getting the Send to AE working. I have it working in AE CS5.5 flawlessly so I thought I would install the AE CS6 Trial version to see if I could figure out the problem.

Here is what I did step by step:

Step 1.

- After I installed AE CS6 I copied the AEtoLW.aex into the AE CS6 support plugins folder "C:\Program Files\Adobe\Adobe After Effects CS6\Support Files\Plug-ins\"

Step 2.

-I opened up AE and clicked on the Edid/Preferences/Reset path to lightwave 3D

Step 3. (here is where I think the problem might be for some people)

- I choose, C:\Program Files\NewTek\LightWave11.5\bin\layote.exe (Make sure you click on the layout.exe file and click open if you don't you will get a constant looping script error)

Step 4.

- I opened up lightwave and clicked on IO/settings (under the Send to AE button)

Step 5.

- Changed the path to the following "C:/Program Files/Adobe/Adobe After Effects CS6/Support Files/AfterFX.exe"

Step 6.

- Just press the send to AE button and the camera data from lightwave should be send to AE where it creates a composition called default (Here you will find the camera)

Everything should hopefully work now

Just wanted to add that I am using AE CS6 version 11.0.0.378, I haven't done any updates yet maybe this could be where the problem exists.

Thanks,
Jason

The larger the markers the more accurate the calcualtion is "Not the scale" that is different... its not terrible consider its a crappy 4meg quicktime movie @ 640

Hmm I don't see any improvement in the slipperyness with larger markers. That is pretty terrible sliding, just about as bad as the full rez (ProRes 422) file.

Thanks for your contribution, though! :)

Hi Jason,

Thanks for both v1.6 and 1.7 files. Each of them have the same issue; slipping.

The 'bouncing' I think you're referring to, ?, is this is a handheld shot. Attached is a test render directly out of after effects with text and tracker markers left in. The 'bounce' is there as well. And the text bounces around with it.

As for 'smoothing' the curves, I'm not sure how that would work, as every frame is keyframed.

Do we have some benchmark footage in the 11.5 content so everybody can work off the same 'page'?

Dillon

Great question!

Seems every other feature of LW 11.5 has some sort of content, or video featuring how it works, except for the After Effects integration.

I'm kind of wondering how to utilize this feature, honestly.

Elements 1.5 (with obj sequence handling) seems to erase any need for 11.5 AE integration? Wish I knew how to leverage LW's AE integration. AE's camera tracker is a no go so far (which is what I was most excited about).

jboudreau, I tried your method and got the same results, it maybe an update problem like you suggested (my update is 11.0.2.12)

Blinkie, I tried your way and it worked! After that I changed a (camera) setting in AE and exported back to LW and it updated as well.

Now on to see if I have slipping problems... heh.

Thanks!

Hi Dillon

Just wanted to let you know incase you were wondering. I updated the AE CS6 to version 11.0.2.12 and everything still works great when it comes to sending camera data from lightwave to AE and vice versa. So I guess the update isn't the problem either :(

Glad Blinkie came up with a solution for you and everyone else having this problem. :)

Thanks,
Jason

its not terrible consider its a crappy 4meg quicktime movie @ 640



Don't want to pi$$ on your chips at all (or be irritating in any shape or form... I swear), but the slippage is pretty bad in that example... even if the footage is bad quality.

Some of the Vicon guys we had training with even said that HD footage can make stuff harder to track, sometimes it's better using lower res video if you can't get a good track.

Haven't tried the AE link yet, but will give it a go tomorrow... good to see so many people clubbing together to get it all working though :D Love this place

Hi Jeric,

I'm not sure why you think the AE render (with tracker markers included) was a bad example. Trackers are rock solid, as is the "TEXT" element. As compared to the same scene put into LW, there's tons of slippage. I uploaded examples of both.

I think the problem is there is no way to tell AE scene orientation and scale to give to LW, as I can do in Matchmover, Synth Eyes, Boujou, etc (I've worked with all of them).

My expectations were too high with AE's 3D camera tracking. The track is rock solid in app, but translating to other apps (especially with a hand held dolly shot, the most challenging) fails. Probably because there is no true translation of scene orientation / scale to the 3D app.

Dillon, I must have confused which was which. ::VIEWS AGAIN:: OK, yes, you're absolutely right the AE is rocksolid.

The LW setup though confused me: did you lay down a groundplane to correspond to the floor in the shot?

Well, if it works in AE, it works, so the tracking is fine, the translation is the issue. Before 11.5's release I used a freebie script to xfer between AE and LW, and it seemed to work dead on, certainly not with the slippage you're reporting. I did eyeball the initial placement of floors and walls (i.e. it's not automatic), but after that worked fine with an AE track. Here's the link:

Considering the confusion on the forum on this particular feature, I hope NewTek prioritizes a step-by-step video to address everybody's questions.

I made another test to make sure that the procedure I am using was not just a fluke regarding bringing in Camera Data from AE to LW and vice versa.

From the test below it definitely works. It brings in the right world size and it also creates the coordiantes system so the grid is in the right orientation to the footage. (Grid Sticks to the footage no slipping or sliding incase anyone is having this problem)

Hey Jason,

Thanks for doing that. I have success at simpler shots on AE, too. I was hoping to do more complex moves like hand held camera dollies, (like the one where I'm walking towards my dog).

I'll try this again with simpler footage to see if I can get a better track. Perhaps I choked the software with a shot too complex for it to handle (to create an accurate 3D orientation and scale to export to LW).

Thanks again.

Thats a nice solid track, Jason. The 2 included videos have a grid + nulls associated with the ground already though (I suspect they came out of LW?)

Hi Dillon

I just made a lightwave preview and exported it out as a quicktime to show you that the grid in layout had all the coordinates set up and sizing and was locked to the background footage. I have the background footage exported out as sequential png files. It's around 450mb that's why it wasn't included with the lightwave scene sorry about that.

I took the footage sequence and tracked it in AE CS6 then I created around 20 or so nulls from the data. I then exported out the camera and nulls back into lightwave. Adjusted the camera for the right perspective and just added a ground layer with a box on top of it to show that their was no slipping. Their is more to the process that needs to be done but this is the just of it. I will post the whole process later if you are intersted.

Also do you have any shots regarding the complex track you are talking about. Something besides the scene with the dog. I would love to see if it works with the procedure I came up with.

Well now I'm becoming frustrated.

I've shot some other handheld / dolly shots and I simply can't get a stable track. Always a rock solid track in AE, but slipping like crazy in LW. Also, the ground plane in LW comes in at odd angles. Usually the camera is positioned below the ground plane. Since there's no way to indicate where the ground plane is in AE, I don't know how you're getting LW grid to line up with the ground (other than to parent everything in the scene to a null and rotate the null around to force a ground plane match with LW grid / scene orientation.

Attached AE and LW previews so y'all can make fun of me. :(

OK, if that's the amount of slipping you're seeing then I don't think it has anything to do with the lightwave transfer. In my tests, objects placed in that scene directly in After Effects follow the track in the same manner. More careful placement in 3d space would likely solve it - the points tracked in this scene are not on a flat plane. If I get a chance I'll take another pass at it.

I already did. Earlier in this thread. I think you saw the comparison and even commented on it.

It's no big deal, there's obvious limitations when doing complicated camera moves (like dolly and trucking shots). There's no way to orient or scale the 3D scene in AE before sending to LW (which is what the pro mactchmoving apps do). I was hoping for a magic pill between AE and LW.

One other thing to check - make sure the footage imported and overlaid into AE has the correct pixel aspect ratio - I think that's the cause of the slip near the sides of the frame in my example, and maybe it bit you too.

I mean like something with a pointer in AE and a similar one in LW so we can see exactly how many pixels or how many frames the discrepency is. But, if the errors are on the order of the TRex bush, ehh.

Does AE play audio real time yet?

Last year I did a corporate video where in one section I flew around in 3D space between different sets of panels and I wanted everything synced to the music. It was much easier to animate the camera moves and the panels flipping in LW than AE because you can actually hear the audio track when you scrub/play the time line without having to do a RAM preview after you've made some changes or hit the . key on the num pad to play the audio without visuals.

Also, aren't there some limits to what Element can do (like raytraced reflections)? I haven't looked at it recently.

Yes, after you've made a preview I think, hold alt and scrub, you'll hear a choppy stuttered playback. Element has no ray tracing at the moment but they're going to be working on that.

kcole
02-07-2013, 10:57 AM
I think I have this licked. It seems that NTSC pixel aspect ratio (0.91), as in the case of the TRex backplate, causes some confusion in the AE->LW transfer. Converting the footage to square pixel aspect ratio before running the 3D track in After Effects resolves the issue. Resulting camera and nulls work directly in LW and match well. There may be a better/easier solution, but with my somewhat limited knowledge of these subjects, this is the best workflow I can recommend.

Also, I'm not entirely sure where the fault lies - is the AE->LW conversion getting confused, or is AE itself doing something wonky with the pixel aspect ratio/camera, to make it work in AE?

First part of vid is original, second part is with square pixels. The 3-pronged pointer is rendered in LW and the red/green/purple dots are solids rendered in AE.

Cody (at NewTek) had posted an AE - LW video that showcased how to use the interchange, and described a step that resolved most of the slipping issues I was having with hand held dolly / trucking shots! But for some reason, the video was taken down. You can find reference to this video in the "Genoma Video" thread just posted this morning.

Anyways, the procedure to resolve this is a scale function (!) inside AE. After applying the tracker and making a few nulls connected to the tracks, you create ANOTHER null, and convert it to 3D space, and then parent the camera and other tracked nulls to the new null you created. Hope that made sense.

Then after you've got the camera and tracker nulls parented to this null you created manually (and converted to 3D space), you then scale the master null so that the camera and tracker nulls come close to the center of the 3D scene (Cody used the title/action safe toggle in AE). He scaled the whole scene to get as close as possible to the center of the screen.

I did the same procedure, and VIOLA! Nearly flawless track in AE *and* LW. Here's an example.

I'm bursting with happy nulls!

Doesn't make much sense to me either (parenting tracked nulls to a master null and then scaling the entire scene to get as close to the center of AE space as possible).

Dunno why the video was removed either. But I've tested it with several different shots, and am now getting consistently good tracks in AE and in LW. Rendering out another example (this time with a background texture and character standing on a real chair). Will upload when the renders are done.

I'm pretty stoked.

Kudos to NewTek for staying on top of this and addressing it in a very timely way!

Each of my tracked scenes uses parenting to a null, a useful habit I picked up from videocopilot.net. This allows you to make the ground plane match up with something reasonable in AE and LW. However it should have absolutely no effect on the track - the camera and nulls, when parented to the same null, remain in perfect sync with each other. As far as I know, the step of parenting to a null and scaling/moving to center is for convenience only. The end result is the same, and this should have no bearing on slip.

kcole

and yet ... it does (for me).

I just ran a test, once with parenting/centering/scaling as normal, once without and the renders are identical. The camera and nulls will be in a different place/scale/orientation in lightwave, which I find better since they match with the ground plane. However, they are the same relative to each other regardless of this technique, resulting in the same render.

I may be missing something somewhere though. Can you do an A/B comparison with the same track and nulls, once before parenting/reorienting and once after? This is the test I did and I would be interested to see if you get different results.

Okay, here's what happened: when the LW scene is exported, the AE camera is way out in the boondocks. If I use an AE orthogonal view and zoom out AMAP, I can start to see the camera motion path. (see attached)

Needless to say, this is inconvenient. (After using LW for years, navigating in 3D in AE has always been a huge PITA.) :lwicon:

That's why I like using LW as a remote control for the camera (and lights and nulls to which things are parented to) in AE. I just adjust the camera motion in LW and update to push the result to AE... at least that worked with AE Link. I haven't tried it with the native solution yet.

I was wondering about that (still baby steps here): are the keyframes translated as WORLD COORDS, so it wouldn't (?) matter, or is it bad and translated as local coordinates, which I believe would necessitate baking motion paths.

:stumped:

(That kinda sounds like it could be a big deal.)

No need to bake motion paths. As long as the tracked footage is square pixel, it works a treat.

So, the motion paths come in fine, but the parenting relationships are discarded?

kcole
02-08-2013, 02:07 PM
The transfer is one object at a time, so there's no way to bring parented objects. In a standard camera tracking, the only thing that moves over time is the camera itself. All the nulls are static, so I've never found the need to bring over parenting.

OK, LW11.5<>AECS6 worked in both directions on my machine, which was cool. Here's what I learned:


When you click "Send to AE" in LightWave 11.5 for the first time, you need to point it to the location of the After Effects executable.
If Export -> Send Selected Layer to LightWave3D does not appear in the After Effects File menu, shut down After Effects and manually copy this file:


<LW11.5 dir>\support\3rdparty_support\AfterEffects\AEtoLW.aex

...to this location:

<AfterFX dir>\Support Files\Plug-ins\Effects\AEtoLW.aex
When running File->Export->Send Selected Layer to LightWave3D out of After Effects, you will have to point it to the location of the Layout.exe file for your installation of LightWave 11.5.
If a null fails to export from After Effects to LightWave, make sure it is a 3D Null object (a cube should appear under the 3D Layer column for that Null layer). 2D Nulls will not export from After Effects to LightWave.

02-10-2013, 05:05 PM
more experimenting.
OK, I'm experimenting with the table footage.... just examined the track and the spatial SCREEN location of the (AE) Solid I added and exported to LW seems dead on (it comes in as a point/null, not any kind of poly-- feature request!), but adding a piece of solid geometry to it slides about quite a bit.

Since the track looks fine in AE, and the location looks fine in LW, I'm suspecting something with the Camera focal length. So, that's next.
++++

Not so much the focal length (although there are some numbers that disagree between AE and LW about the lens), as not having a good perspective. Once I lined up the objects in a way that made 3d sense, the illusory sliding disappeared. In retrospect, rendering out a temporary animation with the solid that AE generated would have made it easier to match the LW object to it, since that was what was supposed to happen.

IOW, a 3d object that seems to penetrate a RW object in the track can give the illusion that the tracking is off, when it is not. It's just confusing to the eye.

Shorter: planes are your friend.

Wonder if this is a limit in AE's Tracker.. Cause it will track a non-square, just seems not to export it correctly.. Course the easy way to always make sure is just set it in the Interpret Footage and set to square pixels. Lands in the right place in LW everytime..

(the so-called "Search" function here is REALLY getting on my last nerve....)

One aspect of the new 11.5 AE interchange capability is that I predict we're going to curse even MORE Lightwave's inability to have 'static objects'. (There's STATIC_CHANNELS, but it has to be applied 9 times, not an ideal solution in my book.)

Why camera tracking? Because I think we'll find ourselves tweaking objects at various frames as we perfect the track, wanting them to be static, and we'll be creating a lot of out-of-place keyframes that will have to be deleted in favor of one at frame #zero. IOW, we'll be wasting our time. A lot.

SO, another plea to NewTek: please make a motion modifier that will A) allow us to keep AUTO KEYFRAME on, but B) will automagically move new keyframes to frame #zero.

Uploading to Vimeo now (14M). Pretty good track, biggest discrepency is ~f300. YMMV, but I think it's satisfactory, and that's w/minimal tweeking and zero keyframing. (Obviously I could mess w/it ad infinitum and make it better.)

Maybe I have low standards.

This footage is particularly easy to track, given the rectangular table w/near linear lines across it, but if a user can get an AE track they're happy with, AE itself can put in a regular rectangle. The key to using this shape (GridCone®) is it gives you an object that is 3d (not flat) and allows you to match the circumference of the cone base to the AE square. You just keep tilting the cone until it matches the square on the majority of frames. And being able to see thru the cone makes life easier too.

I think I did this a bit wrong in that I should have been tilting the Master Null rather than the GridCone® itself, but if you're only matching ONE, STATIC object, this works fine. For moving, multiple objects, matching the key object (GridCone®) using only the Master Null is the way to go.

D'oh!!! THAT'S what I shoulda done! :foreheads

But, to tell you the truth, the GridCone® is merely/strictly an alignment tool. What I didn't show you guys is the "alignment footage" I generated in AE to make it easier to align the LW world to the AE world. Some meshes are going to be very confusing to align: by using the super-simplistic GridCone® it's easy to line it up to the square generated in AE, and then replace it with the actual geometry for the shot. https://vimeo.com/59513520

Getting the shadows semi-right (thanks) took 'wayyyy longer than tracking the shot. Used the SHADOW CATCHER MATERIAL NODE to get the shadows right.

Nope-- that's not my footage, it's 50one's. I hope he leaves it up for others to practice on, it's a perfect test piece.

I just looked at the shadows on the carpet, I have no idea what the light source is although I'd guess a big sliding patio door. TBH, if I were to do this again, I'd add another light from screen right to replicate the ambient light in the room-- that side of the rendered object is too dark IMO. In production I'd probably just do a soft mask on that in AE and boost the level a tad. EDIT: oh and a 'downlight' to lighten up the shadows a bit.

Not that I've ever done that, but I really need to justify my purchase of EXR_Trader.

Hey

If anyone is still having trouble getting a perfect tracked shot from AE To Lightwave just let me know I'm thinking of creating a tutorial if their is enough interest. I came up with a technique that works perfectly and gives you prefectly locked nulls to your footage and a coordinates system (Grid matches correct orientation). Tracked 6 shots with various degrees of difficulty and it came out perfect everytime. Even for those of you that seen the upto speed videos by Dan Ablan (tracking section) I managed to get a perfect track where the nulls locked perfectly to the street shot he used in his video.

Here is the lightwave scene for those that have the project files from the Dan Ablan "Lightwave 11.5 Upto Speed Videos". All you will need to do is import the street view movie into the background and you will see that everything matches perfectly

OK, finally managed to find an easy work-flow for this, my frustration was caused by the not-so-easy aligning the exported nulls and camera from AE in LW, so that the 3D environemt matched the tracked footage[even tho I normalised the Nulls/Camera in AE]. What made the whole process easier was making sure that all Nulls in AE or their Vectors - will face the same directions.

111829

If you click on any of the tracked points in your camera tracker and click "Add Null" AE will just add Null with random vectors[some of them will match, some of the won't, latter in my case], sooo, all you have to do is make sure to select at least three or more points[assuming it's a planar surface] in your camera tracker and then add [B]Nulls and this will make the whole process of aligning the points in AE a whole lot easier - not to mention the LW.

I'm attaching the LW/AE file, you can find the source footage posted in this thread earlier on if you want to import it into AE or LW. I have used the default Ferrari Spyder from the content folder, so it's not attached here.

Hi,

yeah, like I said, after tracking your footage in AE, you'll get all those funky colour-full markers on it. All you need to do is make sure to hold down Shift and select few of them[so it create a polygon] - repeat the process as many times you need - to get 4 or more Nulls aligned - the reason for that is that all your Nulls vectors will face the same direction - in my case the 'Z' vector goes up. When I just clicked on few random points in the Tracker, My newly created Nulls or their vectors were pointing in various directions.

When all the Nulls are facing the same direction(vectors wise) it is much easier to do the normalisation, when you enlarge the Nulls in AE - so you can see them as flat planes in 3D space.

Thanks 50one (let me repeat that back at you to make sure I'm getting it):

So, (to restate what you kindly said above), unselected nulls created by AE's 3d tracker just sorta have random-ish rotation vectors??? BUT the usual AE "selecting trackpoints creates a solid/polygon" behaviour rotates them around so their Z axis is normal to the polygon produced?

When you get back to LW, do you just do the "parent everything to a Master Null" trick to rotate and align a set of LW nulls (exported AE-nulls) to the LW groundplane? (To me, that's one of the more laborious/annoying parts of the process.)

Hey, scripters, a short LScript/Python script to automate the creation and parenting (really should be "childing") of everything to a Master Null would be very welcome.

"Hey

If anyone is still having trouble getting a perfect tracked shot from AE To Lightwave just let me know I'm thinking of creating a tutorial if their is enough interest. I came up with a technique that works perfectly and gives you prefectly locked nulls to your footage and a coordinates system (Grid matches correct orientation). Tracked 6 shots with various degrees of difficulty and it came out perfect everytime. Even for those of you that seen the upto speed videos by Dan Ablan (tracking section) I managed to get a perfect track where the nulls locked perfectly to the street shot he used in his video.

Here is the lightwave scene for those that have the project files from the Dan Ablan "Lightwave 11.5 Upto Speed Videos". All you will need to do is import the street view movie into the background and you will see that everything matches perfectly

Thanks,
Jason




I do not get to make it work the transfer of a LW AF, the camera movement seems equal but different and move nullos Earned leave standing at the point you specify, I have given the scene softened but not doing it I get it to work,
I'm going crazy, you could a tutorial or video tutorial, would be greatly appreciated,
thanks

Hi

What scene are you working with the one I provided in my post or your own?

one on my own, yours if the scene looks good but is not exactly the next steps for me to work in another mine,

Hi

Have you tried this tutorial by Cody Burke, If so and it still isn't working for you let me know :)

https://www.lightwave3d.com/learn/article/lightwave-115-after-effects-interchange/

Although his technique is good and gives pretty good results their is still room for error and sliding using this technique. My technique is a bit different concerning the AE aspect of it and has no errors or sliding issues.

Thanks,
Jason

hello,
I've already tried, but this technique used in other my images not just go fine camera slide remains in lightwave, I will continue trying, thanks

Are you able to provide me with the scene or the footage that you are trying to track?

Okay, Thanks. I will try it on my end and if it works I will try and explain how I got it to work

Thanks,
