Audio Issue

[chukker]

Today is "issues" day for me. Here's another one.

I'm editing a small project in SE2. I have 4 clips of video animation and one audio soundtrack. The project is 15 seconds long.

The audio was recorded with my Zoom, then the .wav file was downloaded to my computer. I edited the sound file in Sound Forge and saved it again to .wav format.

In SE2 the sound won't play smoothly. It jumps and sputters and stutters. When I render the project, the sound plays back smooth in Windows Media Player and Quicktime. The obvious problem is that it is difficult to edit an animation to sync precisely with a soundtrack that won't play properly.

I've got Win 7 Pro (64 bit) on an2.8Ghz CPU with plenty of HD. (I'm throwing this in in case it's relevant). I don't know what kind of soundcard I have.

Maybe try checking the bit rate that you saved the wav file as from Sound Forge.

SpeedEdit 2.1 seems to play 16bit and 24bit audio files but does not play 32bit audio files like SE2 could play.
I don't think bit rat is your problem though.
Are you editing uncompressed video on your timeline.? Sputtering is probably caused by a complex video project. Have you got pre-rendering turned on?
That might help to put a 'force render' effect over the area you are editing.

[chukker]

donx, you've got it - I'm editing uncompressed video. I will try turning on pre-rendering to see what that does. Thanks to both of you.

[chukker]

I'm not sure how I turn on pre-rendering as donx suggested. Could someone advise? I assume it's somewhere in Preferences, but I'm uncertain . . .

Thanks again in advance.

First I would just drop the wav file on the timeline to see if it plays on it'sown. If so, check for floating point audio. Uncompressed shouldnt matter. I do a lot of uncompressed rtv video editing (3 or 4 layesrs at a time) and plenty of audio (music, sound fx, etc) and nothing stutters over here. I think that uncompressed performs better since you do not need the computer's resources to process the decompression during playback.

I am having the same problem with SE2.1. I recorded MPEG 2's on the tricaster and then dropped them into SE2.1 and the audio sounds like it is behind a fan.

How can I fix this? The MPEG 2's play fine in the LIVE mode of the tricaster and on other devices (Mac's), but I can not edit them.

It did conform and looks like it is done, but when i play after conforming, same issue.

[John Perkins]

Can someone make available to me a 32bit wave file that doesn't play back? I just tried it here and it worked, so I'm at a loss.

Beaumon:
Are you using SE on the TriCaster or a stand-alone version?

[Beaumon]

Sent PM.

In Tricaster 850 extreme.

[donx]

Sent PM of a 32 bit float wav file.
These worked in SE2 but not in SE2.1

I'm using stand alone version

[John Perkins]

It looks like this now works in the yet to be released build, but thanks so much for the example.

There must have been another bug that when fixed, also fixed this problem.

[donx]

Perfection is a moving target.

Now if the two monitor display problems get fixed. All will be smooth sailing.

thanks John

[John Perkins]

You'll have to be a bit more specific on those.

[donx]

If you are using two monitors and you load SE2.1 it always places all of the windows on one monitor and they must be moved back into position on the second monitor.
SE2 used to remember the set-up from the last load.

You'll be glad to know that I fixed that yesterday. :thumbsup:

Other fixes off the top of my head:
Crash expanding subprojects with overlay
Crash opening voiceover
New preference setting for "mouse enables play range", defaults to no.
This still lets you use play range with the menus, but it can't be enabled accidentally.

There are others in the pipeline as well, some fixed, some in progress, many having to do with the recent TCXD specific audio and file reading issues. The stand alone version did not have the changes that caused these specific issues.

If you know of others that you can clearly explain how to repeat, please let us know.

Problem with audio, when importing long XDCAM EX files

These files consist of 4GB (or less) in size chunks separated by the camera while recording if the duration exceeds approx. 13 min. When merging the chunks back together placing them butt to butt on the timeline in SE 2.1 video now plays smoothly from chunk to chunk but audio is not yet... There is a gap depending on a frame rate: for 30p it is 1/2 of a last frame, for 60p - 1 1/2 frames etc., and you can definitely hear it...

Would be ideal to allow import to SE from Sony Clip browser directly (Clip Browser does not see the chunks but the whole long clip), the way it works in Edius and Vegas or allow to open Clip browser from within SE. It is possible to drag and drop from Windows Explorer window - why not to do the same with the Clip Browser?..

This would be a major bug fix for me. Please!..

Dear John,

I'm not sure if you've already fixed this or not, but the dual screen issues with SpeedEdit 2.1 are kind of intriguing, if you're using the software on a system with two screens, you may have this problem.

In my exact case, I have a dual screen system, with 2 1920 x 1080 VGA monitors, the left-hand screen is output number one, and is the primary, the right-hand screen is output number two and is the secondary.

Firstly, when I boot up SpeedEdit, I have to have the mouse on the left-hand screen so that the opening project menu window starts on the left-hand screen. If I have the mouse on the right-hand screen when SpeedEdit finishes booting up, it will try to open the file open menu on the right-hand screen. The menu will be invisible, and you cannot click any options because you cannot see anything. The only way around this is to close the program again using Alt-F4 and then restarting it with the mouse on the left-hand screen.

Also, any time I do any menu operations with the right-hand screen, I end up in difficulty. What I mean is, if I select any clip on the right-hand screen and press F8 to see the properties window, the properties window will activate on the right-hand screen but it will be invisible. The program still works as if the window was there and open, but you just can't see it. You also can't drag it to the left-hand window because you can't physically grab it. Of course you can continue editing but you can't click another clip on the left-hand screen and press F8 to get the properties window, because the properties window is already open on the right screen, but invisible.

If you select a series of clips and then right-click, and then select render to generate the clips, if you are on the right-hand screen when you click render, the render window will open on the right-hand screen but, again, it will be invisible and the program basically becomes only limitedly operational at this point. You can continue editing but some functions no longer activate because you have the render window open on the other side, you just can't see it or do anything with it. Again, you have to save, exit the program and restart it, and then remember to move the project section to the left-hand screen, and then click render on the left-hand screen.

Any alert boxes opening on the right-hand screen will also be invisible, but if you know they're there, you can press enter or escape to acknowledge them and return to normal.

If you haven't already, please fix these right-hand screen invisible menu issues, because they happen with all menus or Windows on the right-hand screen. If you don't know that you can sometimes press escape and close the window and get back to the way you were, you may end up with difficulties and have to reload the software.

Best Regards,
Mutley Eugenius

Same problem. If you resolved this please post how you did!!! Otherwise thread is kind of useless.

System just reset to factory defaults: Same problem as described above: audio sputters, video plays back erratic stops and starts. Clips were captured in tricaster, play back normal as files in Live mode and if exported. just in SpeedEdit do the files not playback. I looked all over for anything that resembled "Pre-render" and can't find a setting for it.
Please advise.
Thanks

I looked all over for anything that resembled "Pre-render" and can't find a setting for it.Prefs has settings that determine what is "background rendered" and what is not (separate profiles for SD and HD projects).
