Production's ffmpeg, Debian's 5.1, refused the copy of Brad & Will's
359: "Error initializing bitstream filter: bsf_list". The frames to drop
went to it as between(...)+between(...)+..., which nests a level a term,
and 5.1 takes 100 terms and refuses 200; the 6.1 the tests ran on took
all 520. Summed as a balanced tree the same 520 nest about 10 deep, and
5.1 takes 4000 that way, checked in the production container.
The failure was also stored as the file having no copy, so nothing would
have tried it again after this fix. Failures are now remembered until
the next start instead. The cap on cuts drops to 3500, so the argument
stays under Linux's 128 KiB with frame numbers in the millions.
