I am really impressed by Hybrid so far, using vapoursynth, rock solid, seems to properly utilize GPU and much faster than megui+avisynth, which would sometimes stall or crash after many hours for no apparent reason.
I digitized our family archive of Video8/Hi8/Digital8 many years ago and recently started to deinterlace them with QTGMC to mp4 for easier viewing from the phones, network players etc, still keeping both the tapes and interlaced avi files for archival purposes. Really happy with the results visually, just have a question about color conversion:
When I look at the generated .vpy script I see that the source is properly recognized as 4:1:1, converted to 4:4:4 for QTGMC and then to 4:2:0 for x264. No crop or resizing, the output is 720x480 with 59.94 framerate. I have only basic understanding of color spaces and conversion but I always assumed that if no resizing is performed it is better use resize.Point option instead of resize.Bicubic for color conversion? I see an option in Filtering/Vapoursynth/Misc/ColorResizer but it is greyed out and Bicubic.
Color wise the result looks the same as original, just wonder if I am missing something.
