    Hello!
    I need a weave deinterlace plugin for Progressive Segmented-Frame videos in Adobe After effects. The After effects reder only the half resolution of my camcorder video-files, my camera record in Progressive Segmented Frames ((((
    Can you help me?
    Thank you!

  2. You can encode them to a lossless intermediate using another decoder eg. avisynth + ffdshow . You can use lossless compression e.g. lagarith, ut video codec , but AE works in RGB (camera files are Y'CbCr - so there will be slight quality loss even using AE)

    The problem in AE is not just interpretation as interlaced, otherwise you could just right click and interpret the footage as progressive - but this doesn't solve all the problems (you probably already tried). Even native progressive 24pN has this problem (but not as bad)

    1) interlaced chroma upsampling

    2) nearest neighbor algorithm, point resampled chroma (blocky color edges), especially poor for YV12 (4:2:0) upsampling - this affects everything, not just AVCHD

    See this old post from ~2 years ago

    The solution is to use digital intermediate , either upsampling to Y'CbCr 4:2:2 or RGB, using a better algorithm. For example some people use cineform, mac users use prores, others use 5DToRGB. Avisynth workflow is free

    Premiere CS5.5 has improved the interlaced chroma issue, but still low quality "blocky" colors from nearest neighbor upsamplling
