Try disabling pre_capture and see what happens.

There has been some traffic on the Raspberry Pi forums about video
problems with Buster. I don't currently work with video on my Pis, so
haven't paid an enormous amount of attention to it, but I thought that
some initial problems had now been addressed. Make sure that your OS is
fully upgraded (sudo apt update; sudo apt dist-upgrade). In addition, if
you *literally* upgraded to Buster from Stretch (went through the OS
upgrade process, rather than installing Motion on a newly-created Buster
SD card, you may want to try the latter option. Upgrading between
releases is deprecated for good reasons.

Much better, more like the other machines. I see now that the doc warns
against pre_capture, I'd missed or forgotten that, so thanks very much.
For some reason the newer release of Raspbian must have been more
sensitive to that setting.
I set framerate low, to 4, because I didn't want to overtax such a small
machine. I'm wondering if that's a reasonable setting for a Pi Zero, and
what other folks' experience is. I rarely see 4 fps in the captured
videos, i.e. still missing frames. Now having set pre_capture to zero, I
see maybe 2 fps in the playback, but maybe this is due to other factors.
