    Any idea how I can do that? The a/v is in sync in the avi, its just at 25.0588, and I want 25fps. I have about every program, avi info, vdub, tmpg, cool edit, and I can't figure it out.

    Would it be easier to go for 29.97fps? ..Thanks.

  2. You know what, i want to do the same thing, i want to convert 24.32 FPS to 23.97 FPS, but i cant figure it out without losing sync either. Vdub loses sync if you change the FR, you can do it in TMPGEnc without losing sync, but the output AVI files will not be recognised as an AVI file, can be used in divFIX cant be played in any media player either.

  3. Just separate the audio from the video, use Vdub to encode at the slower speed, and use something like CoolEdit to change the video speed by the appropriate amount - works great. You don't hear the slight change in audio speed (of course, use the setting to preserve pitch when you change the speed!)

  4. The .0588 probably isn't that important, people. Framerates are rarely exact. For example, my video captures off of cable are usually 29.96 something, not 29.97 exact.

  5. Kineera, i have a movie in 24.32 (idiotic framerate) instead of 23.97, but when i convert the 1st 70000 frames, i lose 120 odd frames converting to 23.97, or about 60 frames converting to 24fps, TMPGEnc cant preserve the 24.32, the closest is 24. Anyway, my point is, the audio length is the same, but the video length is 60 frames shorter, so by then end, the video is over 2 seconds out of sync with audio! even though TMPGEnc should keep sync, it doesnt!

    TMPG changes the framerate, and I lose audio sync .. I would think .0588 wouldn't be much, but over the time of 45 minutes, audio gets off about a second or two.

    Well I tried this to fix my problem, and it didn't work.

    vdub the avi of 25.0588 to 25fps with no audio. It made the movie from 44m39s to 44m46s. Sent the audio to a wav file, then in cool edit, I stretched it from 44m39s to 44m46s.

    Put them both in tmpg, and it still is off...even more so. Any idea why?

    Gee i love people who dont think b4 they post. 0.5FPS over a period of 95 minutes, or 45 in the ohter guys case, is going to make a shitload more difference than 0.01FPS, dont you think?

  8. The amount in question is .05, not .5, and the real point is that it sounds like that framerate is a result of timing inaccuracies that are always present when video capture cards do their thing. In any case, if the source is AVI, your best bet is to frameserve it out of VirtualDub. This places the burden of synchronization on VirtualDub. It also affords you the opportunity to try using VirtualDub's option to match the framerate to the audio length, which might also solve the problem.

    In any case, I was directing my response towards the first poster, whose framerate difference is clearly less significant than yours.

    Finally, if you a*holes insist on insulting people who are volunteering their help, you may soon find that posts like this go unanswered.

  9. make it easy on yourselves... (upcoming: the standard answer)

    1. extract the sound stream
    2. adjust the length of the new sound stream
    3. fire up tmpgenc
    4. settings / advance / do not framerate conversion
    5. audio source: your new sound stream

    ... and go...

    Yeah it was no problem, I fixed it.

    With vdub, I extracted the audio. Changed the framerate to 25.000 from 25.0588. Doing that, it changed the time of the video from 44m39s to 44m46s240ms .. I just went in to cooledit, and stretched (saving the pitch) the audio to the extact time of the video. TMPG, I put them both together, and it was done.
