Thanks, Carl Eugen. I'm certainly deficient in my knowledge of ffmpeg, so
I know I'll have to move to the ffmpeg users list right away, but I'm
going to ask here first. I have an old conversion command that, though not
pretty, does create output.

ffmpeg -i infile -b:v 8600k -bt 570k -minrate 7000k -maxrate 9000k
-bufsize 2310k -i_qfactor 0.71 -mbd rd -r 29.97 -s 720x480 -aspect 16:9
-trellis 2 -cmp satd -subcmp satd -precmp satd -g 15 -qmin 1 -qmax 50
-threads 8 outfile.mp4

When I take a stab at adding the filtergraph suggested by the docs you
linked:

ffmpeg -i infile -vf "fieldmatch=order=tff:combmatch=none, decimate" -b:v
8600k -bt 570k -minrate 7000k -maxrate 9000k -bufsize 2310k -i_qfactor
0.71 -mbd rd -r 23.576 -s 720x480 -aspect 16:9 -trellis 2 -cmp satd
-subcmp satd -precmp satd -g 15 -qmin 1 -qmax 50 -threads 8 outfile.mp4


I get:


No such filter: 'fieldmatch'

Can you point me in the right direction? I compiled ffmpeg this morning,
but do I need to build it a particular way to include "fieldmatch" among
available filters, or do I just need a different command? Thanks again.
