    I am using CCE to encode an avi file and then the PullDownBatchFE to convert the FPS to an aceptable FPS (29.97) so tha i can author in TMPGEnc DVD author. But after i convert the FPS the video and the audio get out of sync. What can i do to resolve that problem? Is there a tool to convert the audio? Am i doing something wrong?

    Please someone help me... :)

  3. After wasting hours and days (I won't admit how long, because it is embarassing), on framerate conversions. Trying every method I could, including DGPulldown.exe...

    for me, avisynth and "ConvertFPS(29.97)" worked on two movies that I could not get ANYTHING else to work on, and the quality was fine for me, your mileage may vary, but I would recommend you at least look at it (if you are familiar at all with avisynth)

    The FPS of the avi file is 24.
    And when i tried to use the "convertFPS(29.97)" on the avyscript CCE did not openned the file...: "frame size 932x56 is not supported . Supported frame size is up to 720 x 556"

  5. since I always do the resizing in the AVS script, I have never tried not resizing prior to importing into CCE.

    I am using CCE 2.70... I just did a "test" of using the un-resized script, it encoded it fine without clicking the "for dvd" checkmark (although, odviously the created mpg clip will NOT work on DVD due to the wrong resizing), and also worked with "for DVD" selected, which in turn resizes to 720x480 (without borders, so the aspect ratio is messed up....)

    Using an avisynth script of:

    AVISource("D:\ConvertFrom\somefile.avi",pixel_type ="yuy2")
    ConvertFPS(29.97)
    BicubicResize(688,260,0,0.6,1,0,593,246)
    AddBorders(8,104,8,116)
    with your resize and border settings being correct for YOUR file, NOT MINE

    and

    CCE settings as seen in the attachment

    (DVD Checked = Resizing done in CCE, unchecked = resizing done in script)

    P.S. If I am saying stuff you already, no, I apologize, not trying to talk-down

    No, that CCE message has nothing to do with resizing, but refers to an AviSynth error, just about any error. In this case it's because he didn't do a ConvertToYUY2() before using ConvertFPS. Before opening the scripts in CCE, it's always a good idea to test them out first in VDub(Mod) first, because if something's wrong, it'll give you a real error message and help pinpoint the problem.

    To keep the audio and video in synch, one way is not to run regular Pulldown, which is a recipe for asynched audio. given that the AVI framerate is 24fps (without ConvertFPS). Instead use DGPulldown, with the Custom box ticked and 24->29.97fps. This assumes that you haven't screwed up anything else, like doing a bad conversion of VBR MP3 to AC3.

    And ConvertFPS(29.97) is a very bad way to do it, as then you're unnecessarily encoding all those extra frames (25% more, just about), and introducing stutter and blending into the video.

  7. I wish I could get DGPulldown to work, but on the two movies I tried (following instructions) I had sync issues =[ I know it's not "great" but at least it reapeatdly produces synced audio. I can watch blurring/stutter but I cannot handle audio off by 10 minutes =]
