I want to be able to track the motion of a camera and export the camera motion to a 3d application. Can after effects do that?

Hi

Im not sure if after effects added motion tracking to its feature set in later versions.
I can however recommend syntheyes, a cost effective dedicated motion tracking solution that exports to Lightwave just fine.

Ugh... I recently came across a free plugin to convert AE motion to LW that I tried and it worked and now I cant find the damn thing. Searching...

Absolutely agree.
Syntheyes has proven itself with us; quick, not pricey, awesome results and the customer service is ace. :thumbsup:

After effects can do 2D motion tracking, and a kind of faux 3D track with corner pin (unless someone knows a trick I might have missed....) though this is not the exporting of 3D data that LW can use really, but for a more than decent 3D track, you'll be pushed to beat Syntheyes for the money.

I learned BouJou in school only to find out that it costs $10,000 (maybe a little less at the time) I've downloaded VooDoo tracker but haven't tried it yet. It looked rather complicated though. If the OnLive (http://www.onlive.com/) service works for video games I'm hopeful that they can somehow get it working with programs that are too expensive for an individual or small studio to own.

Depends what you want. AE only does 2D tracking, which is no good if you need your camera to move in 3D space. If you're looking for excellent 3d and tripod shot tracking, thta will compete with the big guns, but at a fracton of their prices, check out ssontec.com as someone else suggested. I cannot comment on the free ones, but Synthesyes rocks.

motion tracking , or match moving , after effects has motion tracking , which can be done easily with motion tracking tool . its a matter of clicking on certain key point which stay in frame . www.videocopilot.com plenty of stuff there to show you .

Use the search facility on NT forum , theres another post which i remember briefly that covers this subject in more detail voddoo trackers free and relativily easy to use .

I use a little bit different approach, sort of a poor-man's workaround but it works like a champ, renders quick, and AE handles it no problem.
First I drew a picture of a nice tracking target in PS...can be anything you want with nice sharp lines. Black and white for maximum contrast and trackability and fairly hi res if you need it to be close to camera.
Mapped the image to a single poly object and named it "Target" (or whatever)

Import "Target" into copy of your scene and place it where you want the final composited object to be.
Do a separate render pass using only the target. You wont need AA or motion blur etc...so it renders extremely quickly.
import the "Target" footage into the same composition as your master scene in AE for tracking...you see where this is going...

I was compositing a man standing in a miniature set, so I put the target image over a picture of a man (around the belt area since that area seems to move the least) and sized the poly to the approx dimensions of the man...this made camera framing in LW pretty much foolproof...

When compositing the footage of my actor, I made the anchor point the same spot where the target was (the belt area) and it worked like a champ.

I think it takes longer to type this out than it did to do the composite in real life...its so simple...

I'll post a clip that I used this technique on when I get to the office on Monday if you are interested...but its pretty quick and simple albiet low-tech...I may not be the best at explaining things, so let me know and I can post some screen grabs if you want.

Cheers!
:D

Let me in a little secret.

With AE Pro you got Mocha tracking, but they haven't put shortcut to it. Very useful and free, and you basically copy/paste motion tracking data from Mocha to AE.

I used it a few times and its quite good.

I normally use PFTrack which is able to save to LWS format. No hassle, all good!

Cheers!

Hold on, I have AE Pro, and I'm not aware of having Mocha. How do I acces this?

Voodoo tracker you have to load a sequence which is pretty strange if you are using live footage to track.

Not really. I used Boujou on live footage and it was all converted to sequences first.
