![]() So Vimeo just doesn't like this specific project, which leads me to believe that their encoder or player is more fragile/sensitive/finicky than Youtube's. This project doesn't cause this issue on Youtube, but on the other hand, my other projects don't cause this issue on Vimeo. I'm leaning toward this being some very subtle issue with my project that is triggering a bug in Vimeo's encoder or their player. Since not all Vimeo users are experiencing the problem, this leads me to believe that there is something odd in the encoding settings that is causing heartburn (technical term) to the Vimeo encoder. If you go back to the OP's Vimeo link, I'm sure you can find the download link for this version of the file and verify this. This seems to indicated that Vimeo was having a problem determining the proper length. When I played this in VLC, or when I put it on the timeline in Vegas, it was 3x the length of the original, but the last 2/3 was blank. One clue (and it may be a red herring) as to what is going on is that when I first downloaded the MP4, I wasn't signed in to Vimeo, and all it would let me download, as a guest, was their version of the 1280x720 video which was only 60 MB. Musicvid10 (and others): Can something like this happen if the MP4 isn't encoded with the "right" header? I know that earlier versions of Vegas didn't include the "fast start" information, and that some of your YouTube tutorials (I think it was you) showed how to use MP4 Fast Start to remux the MP4, without re-encoding, so as to include this information. Oh, also, all the video is from a Panasonic GH2, if that makes a difference.Ĭomplete name : \Media\Card1\PRIVATE\AVCHD\BDMV\STREAM\00001.MTS I did use a couple of clips that had a different frame rate (29.97), but they were much later in the timeline from where the sync issue is first noticed. One more thing I should mention before the mediainfo output. ![]() Here's the latest upload that I've made: - you can see the sync issue on any face to face interview clip. I will be happy if I can get it resolved with a direct Vegas render, without the extra step of intermediate and handbrake.ģ. However, the DNxHD intermediate and Handbrake compression can be eliminated from the equation because I got the same results rendering directly to MediaConcept AVC mp4 in Vegas. When I selected quicktime and DNxHD, I only had odd audio codecs to select, so I chose uncompressed. I will paste the media info at the end of this message.Ģ. ![]() 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.ġ. 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. I wonder if there is just some inconsistency with this specific Vegas project that is causing the player to break? 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. 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. ![]() I spoke to Vimeo support and they sent me a checklist, most of which I had already done. 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.Īt 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. 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.
