Hello all, I am posting this in hopes that someone with Vegas experience may have run into a similar issue and been able to resolve it. I have uploaded a nearly 14 minute video that I've edited in Vegas Pro (12 build 770) to Vimeo, and no matter what I try in terms of render settings the audio always appears to be out of sync by only a few frames.
At first I had been rendering to a DNxHD quicktime intermediate and then converting to mp4 in Handbrake, but after struggling for a while I figured it may be related to that workflow, so I went to a straightforward render to mp4 directly in vegas (which had worked for me in other projects in the past), but the problem persisted.
I spoke to Vimeo support and they sent me a checklist, most of which I had already done. However, that list did help me discover something new: I found out that the problem is only happening in Firefox! I have tried Firefox, Chrome, and Internet Explorer browsers on 3 PCs so far, and on every one of them the video is in sync in Chrome and IE, but out of sync in Firefox.
If I upload it to youtube the video is in sync on all 3 browsers, which leads me to believe that it is a problem with Vimeo's player, but I also have older uploads shot on the same camera, same settings, and edited and rendered in Vegas (older versions) that don't have this problem on Vimeo. I wonder if there is just some inconsistency with this specific Vegas project that is causing the player to break?
Has anyone ever run into a problem like this and found a solution, or do you have any suggestions of things that I can try to do to resolve it? I have already tried rendering at various video and audio bitrates, but have not tried changing the video frame rate (23.976) or audio sample rate (48kHz) from the source footage.
My next step is to look closely at each cut in the project to make sure that none of them are sitting outside of frame boundaries, which will be a pain.
Any help would be greatly appreciated.
