Rendering: Audio Out of Sync
when i render a video the audio gets out of sync, it will be in sync in the preview window the whole way through, but after its been rendered it will usually be in sync for about 60% of the video then it will be just slightly out of sync for the rest of the video. it just starting doing this, i havnt messed with any of the settings or anything. im rendering in svcd not sure if that will have anything to do with it. any help will be greatly apreciated, thanks

Where is your footage from?
How do you play the rendered video? -
i capture the video using my ati all in wonder video card, i capture it to either dvd format or avi format. i use media player to pay the avi or power dvd to play the dvd file. but thats not the issue. the issue is that the video plays fine before its rendered and it plays completly fine in the preview window of vegas but after its been rendered in either the svcd or dvd format, it goes out of sync just slightly after about 60% of the video. its the weirdest thing because i only have a problem with captured video. this problem just started, it has worked fine then all of a sudden it started. i have uninstalled and reinstalled vegas, but still the same problem. thanks

Hi,
_This_IS_ the situation where virtualvcr
will help.Should take at look at this:
https://virtualvcr.sourceforge.net/html/virtualvcr/sync.phpAnd this thread:

the problem isnt capturing though. my problem is after its been rendered its out of sync after about 60% of the video.

I guess vegas treats somehow different, while rendering versus
playing from timeline.
I had similar problems using ati rage fury pro vivo.
(While you play, there may be some
time correction somwhere in directshow, which is not present
in render time.)Nowadays I have better hardware, but please,
believe me, the problem is in capture,
just does not get manifested until you want render.Give a try to virtualvcr, it stopped me pulling my hair
out. :))And capture to avi using some fast codec, mjpeg or huffyuv.
Capture audio as uncompressed.
DO NOT capture to mpeg.Good luck!

[cdmanproductions] “the problem isnt capturing though”
I’ll disagree. The problem IS because of the way you are CAPTURING. Buy the hardware you mentioned in the other thread and capture via firewire. Your “problem” should disappear at that point.

i tried virtualvcr and the same thing still happens. i understand that my hardware isnt the best but it does get the job done. im just trying to figure out why all of a sudden after it worked fine for such along time it starts doing this. thanks

Resample Audio – Dynamically option checked?
If not, check it, otherwise try other sample rates
(44.1, 48 etc)If none of these helps, I’m stuck…

nope still does it with no matter what prgram i capture it with. the only way it wont be out of sync is if i pull video off of a dvd.
