Activity Forums VEGAS Pro Audio sync problems

    **I have Vegas Pro 10.0**
    I’ve recently gotten into making MW2 Frag videos but i’ve noticed a lot of times that my audio is like 2-3 seconds before or ahead of my gunshots. I’ve read a forum about some audio options vegas pro and they helped but only for a few minutes. Then i also tried just saving and restarting sony vegas, but then again it only lasted a little bit. I record with fraps and i play on my laptop, i record at 30 fps like most people say to do, but it always lowers from 8-18 fps which is really troublesome. Does anyone have suggestions of a way to fix the audio problems? Should i just find a new recording program that stays consistent with fps?

    My guess is that your computer doesn’t have enough power to do a real-time playback.
    Render the file out to the desired format and see if you still have the problem.

    It is still not syncing right. It can’t be my computer because i’ve made videos before with no problems as far as audio goes…

    After you render the video, what player are you watching the video in? Have you tried VLC? If not, you can download it from videolan.org.

    Depending on what version of Vegas you have, version 9 and 10 pro adjust the framerate for you on playback in the preview window to allow for smoother playback. Once you render it, the only things that would cause it slowly drift is 1. your hardware or video player can’t handle the video. 2. However you capture the video allows the audio to drift over time. Number 2 is fixable in Sony Vegas, just split the audio before it becomes noticably off (like a gunshot a slightly ahead of the gun going off or slightly behind) and shift it slightly to the left or right on the timeline until it is back in sync. Do this every so often until it is where it should be and then render out.

    What format are you rendering to? For a simple test, render out to wmv and see if you still have the issue while playing it in Windows Media Player.
