Please remove the input option -r unless you know exactly what you
are doing.
-filter_complex [0:0]crop=704:480:8:6,pullup
Input on ticket is 4:2:0 and you can't crop vertically interlaced
4:2:0 by 6 without messing up the chroma. AFAIK you need to crop 4
lines at a time.
Maybe you could crop 6 if you converted (interlace aware) to 4:2:2
crop and then interlace aware back to 4:2:0 (untested!).
Hmm, after looking at the trac sample I think the chroma has already
been scaled progressive = broken sample.
I may be wrong! only looked quickly.
