Comment (by Devin Heitmueller):
Confirmed, using the following command line yields much better results, as
the cc_fifo actually repacks the 608/708 tuples to the appropriate target
framerate:
{{{
./ffmpeg -i ../../AIM-2301.mp4 -vframes 600 -pix_fmt yuv420p -c:v libx264
-flags +ilme+ildct -x264opts tff=1 -vf fps=30000/1001,scale=1920x1080 -b:v
25000k -codec:a aac -ar 48000 -threads 0 AIM-2301_x264_24tohd_3000.mp4
}}}
(the only material difference in the above command-line from the one in
the original ticket is the filename and using "fps=30000/1001" rather than
"fps=29.97")
