Help! audio badly out of sync w/video!

[Thomas Wildgen]

Rick,
I want to thank you for the tips you passed along, the one about Matching settings button has been very helpful and has solved problems with a bunch of the files with sync issues.
However, the 2 files that prompted this thread are still problem children.
I have tried output in the same format as the media on the timeline and various other tries but the they are both still out of sync-badly.
Is there any “hidden info” that I can check or something that is not shown in the clip info that would affect the sync?
I have a question posted on the Sony help website as well.

Sorry Tom I don’t have any other tricks up my sleeve.
Perhaps Sony Tech Support can help.

Regards, Rick.

I’ve tried the Match Media Settings, and it sets the video preferences to NTSC DV 720 x 480 (which does indeed correspond to the aspect shown in the properties of the clips.) However, in both the timeline and the preview, the clips appear as if zoomed in on, so I have to manually set the preferences back to the NTSC video CD setting to have the whole clip appear.

Can you tell me why this is? And how will this affect the resolution if I render under NTSC DV?

Thanks.

🙂

It seems that all Sony editors have this problem. As odd as this sounds, I’ve noticed that bad synching seems to happen after I’ve expanded the tracks, then collapsed them again. I have no idea why this would make a difference but….

I recently experienced this audio out of sync problem using Sony Vegas Platinum 9.0.

I imported a *.ts file generated by WinTV. (I am converting old VHS tapes to DVD format and inserting menus.) SVP imported the *.ts file well and on the SVP timeline, the audio/video were in sync. When I created the mpg/ac3 files for import to DVD Architect, the sync problem appeared. I tried different project/rendering specs without success. Finally, I downloaded (free) software that converted the *.ts file into a *.mpg (mpeg-2, I believe) file. When I imported this converted *.mpg file to SVP, the audio sync problem was clearly apparent on the timeline. To correct it, I stretched (in SVP) the audio tracks to match the video. I did this visually by picking a sharp noise with action toward the end of the video. The final result, in DVD Architect, was perfect.

I think the problem, in my case, arose from how SVP deals with *.ts files. I don’t know if this is the same problem described above in this thread but I thought that I would post this here in the event others have an audio sync problem.

Vegas Movie Studio 10 fixed this issue by simply not loading the Audio and/or Video tracks, vr 9 Still has issues and I am STILL looking for a resolution myself!

I am also looking for a way to sscroll my timelines manually when the audio is out of sync BUT simply displaced, The timeline SNAPs to a breakpoint and f8 shift-f8 cannot fix it!

The last 3 posts in this thread seemed most relevant to my situation UNTIL I realized that the separate music track that I inserted was in sync with the voice track included in the .TS file. If sync within the imported *.TS files had anything to do with it, wouldn’t the separate .MP3 music file I imported be out of sync with the voice soundtrack from the original *.TS files?

In this case, the audio seems to be in sync with the original SVP timeline throughout the rendered movie, yet the video falls behind at a rate of 1 to 2 seconds per minute of rendered production. The video length is 12:34:58 (mm:ss:??). Around 11:30:00 into the movie, the video track is ~20 seconds behind where it should be according to the SVP preview timeline. Get this: the video speed during the last minute of the rendered movie then accelerates logarithmically to the point where it’s playing double-speed fast-forward, finally catching up ultimately land at the correct point on the timeline’s final frame.

I have tried different rendering settings, including having the movie’s audio & video be identical to the original imported files. Same result.

Toshiba Satellite A505-S6005
Intel Core i3 CPU: M 330 @ 2.13GHz
Intel Graphics Media Accelerator HD version=8.15.10.1986

(PS: I really am evaluating the SVP software with intent to purchase IF it works with my hardware. I have used Windows Live Movie Maker with absolutely no rendering problems. Why now?)

I’m not sure how you do it, but Studio 10 you can turn off the snap.

[Juan Alvarez]

try rendering 32Khz instead of 48Khz audio and reply if OK or not

Which free software did you use for the conversion from .ts to .mpg?

Does it do high definition?
