Исходник + crop / часть фильтрации / фильтрация / энкод

Обработка в AviSynth:
DGDecode_MPEG2Source("Video.d2v") # 720x480p30, сделано из i30 путем dumb bob и отбрасывания половины кадров.
QTGMC(InputType=2, SourceMatch=2) # починка плохо деинтерлейснутого материала.
crop(2,0,-2,0)
Dither_convert_8_to_16()
Dither_Resize16(640,360) # даже еще меньше можно было
DitherPost() # изменение размера с дизерингом
