Stuttering and synch problems after export to H.264

Apr 18, 2012 9:23 PM

Tags: #export #h.264 #stutter #h264 #synch #stuttering

I edited some AVCHD video in Premiere Pro 5.5.0, rendered a 5 minute sequence, and exported to H.264 for Vimeo, using Vimeo's guidelines:

NSTC

1280X720

29.97 fps (as shot)

Progressive

Square pixels

CBR 5 Mbps (tried VBR 1 pass and 2 pass as well, with no difference)

Audio output AAC

44.1 khz (from 48khz original)

320 bps

bitrate precedence (tried frequency precendence first, no help)

 

The export plays fine in VLC player 2.0.1, but in Quicktime and after uploading to Vimeo, the audio plays well, but the video stutters and is mostly out of synch.

 

If it makes any difference, MacBook Pro, 9Gb RAM, Mac OS X 10.7.3

 

Any ideas?

    What's the Vimeo link?

     

    QuickTime is one of the worst players out there.  VLC is a good one.

    Well this is weird, and a likely candidate for the Journal of Irreproducable Results. I deleted the videos from Vimeo last night just before I posted to this forum. I then shut down the computer for the night. Booted up this morning, and the H.264 export played fine in QuickTime, and in VLC. So I uploaded it again to Vimeo here: https://vimeo.com/40655208 (password protected, by the way, intended for my client's approval. PW = DIYEFT) and it now seems to play fine.

     

    To say I'm puzzled doesn't begin to describe it. If my internet connection had been slow last night (Time Warner cable, not the quickest out there) that might help explain the sutttering on Vimeo, but it wouldn't explain the similar stuttering in QuickTime.

    I was actually thinking it might be your system.  That's why I asked for the Vimeo link.  It wouldn't be the first time it stuttered for the poster, but not for others who test it out.

     

    The restart seems to confirm this.

    Make sure that you've installed the Premiere Pro CS5.5 (5.5.2) update. It fixes a lot of problems.

    I'm having this problem consistently actually.  I'm using the built-in preset for Vimeo HD, and play back in QT stutters, but is OK in VLC.  I've rebooted, I've reinstalled QT.  It would seem like an issue with QT and the media encoder (though I don't know how/why VLC plays it ok.  It does seem to play ok on vimeo also - and I'm uploading a test video now (perhaps it's just QT itself, it's still really annoying).

     

    I'd be happy to work with someone to go over troubleshooting steps - it's very frustrating - this used to work fine for me in CS5.0.  I currently have CS5.5.2.

     

    Any thoughts?

    It is.  Best bet is to just not use it.

    Sorry to take so long to get back to this—I've been on other projects. I did upgade to CS 5.5.2, but it did nothing for the stuttering problem. If I reboot, everything plays fine in QT.
