My script is very heavily based on
this post in Andrew's blog.
Like in his post, my input video is SD DV, yuv411 and 601 color matrix, so I just went with his approach. Much of this stuff is well over my head!
Do the processing steps prior to that final resize affect the color matrix? Is there a way for VapourSynth to tell me the color matrix before and after a processing step?

Good catch, if I understand correctly, this only affects compression ratio and output file size, right? So I could go say "medium", without affecting the video quality right? Just use more disk space (I've got ~20-30 TB available, so no biggie).

Interesting idea! You mention bob deinterlacing. QTGMC produces such nice deinterlaced output, is there a reason I'd not want to use QTGMC?
