    Hi!

    I try to convert interlaced PAL DVD using RipBot264 and not sure if this script is correct and here is the sample from the DVD, Thanks in advance!

    MPEG2Source("H:\Drive\Work\Test.d2v", cpu=0)
    Import("C:\Program Files (x86)\AviSynth\plugins\QTGMC-3.32.avs")


    AssumeTFF()
    QTGMC( Preset="Faster" )
    Srestore(frate=25)
    Greyscale()
    Crop(8, 0, -4, -0)
    Image Attached Files

    Your demuxed sample was originally created as film at 23.976 fps. The film was processed with telecine (2:2 pulldown) for 25fps playback, and not as pure interlace. Then was encoded as progressive, which field-blends the telecined frames. To restore the original playing speed and eliminate blended fields:

    Code:
    MPEG2source("demuxed.d2v")
    QTGMC(preset="super fast",border=true)
    sRestore(frate=23.976)
    The movie was already produced as greyscale. If it doesn't look greyscale to you, your monitor needs calibration.

    The statement "srestore(frate=25)" will do nothing to remove the pulldown. If you don't want your movie to play at its original 23.976 speed but want it to play overly fast at 25fps, add AssumeFPS("PAL_video") after the last line, then check if audio is still in sync. But why would you want it to play overly fast?

    When you create a demuxed d2v project with DGIndex, the app also demuxes the audio, probably here as an AC3 audio file. You can combine audio and video in Avisynth using the NIC plugin (http://avisynth.nl/index.php/NicAudio), in this manner:

    Code:
    vid=MPEG2source("demuxed.d2v")
    aud=NicAC3Source("path/to/FileName.ac3", Channels=2)  ####<- set path and filename for your audio file
    AudioDub(vid,aud)
    QTGMC(preset="super fast",border=true)
    sRestore(frate=23.976)
    return last
    Video and audio will be in sync at 23.976 fps.

    Thank you so much, LMotlow for your help. I use BeSweet (I slowdown the audio 25> 23.976) to create PCM audio file then I convert it into AC3 using Sound Forge (AC3 Pro Dolby Digital), but I will try your way Thanks again!

  4. The video was produced with the field blending technique so as not to change the movie's original running time. Using LMotlow's script will leave you with that same running time (and keeping the original pitch) so there's no need to adjust the audio.

    As noted, the movie is pure greycale already. It doesn't hurt to call GreyScale() but it's not necessary.
