The settings I used (for ffmpeg 3.2.2.3 running on Mac OS X El Capitan via
MacPorts):
ffmpeg -i A%04d.png -vcodec libx264 -pix_fmt yuv420p -r 60 A.mov
The clock values in POV are set for a 24-FPS film, but I have to set -r to 60 to
get rid of herky-jerky frames that hang every second of runtime. I'm sure
there's a long and convoluted technical reason for it, but I have no clue what
it is (and as long as -r 60 solves my problem, I don't care)...

Did not work either... could it be that my Firefox uses a crappy Flash
plugin?
See you in Khyberspace!

Does it look good locally? Use VLC to play movies on your PC, for best
results.

It is a bit better in Chrome but not much. Internet Explorer gives the
best view of the 3 browsers I have. It still looks grainy but not blocky.

Meanwhile, I tried Konqueror (as I'm a Linuxer) - and, yes, it looks
much better, although still somewhat "compressed"!

It seems to be mostly a matter of the browser used... I tried displaying
it in Konqueror, and it looks MUCH better!
Another question: may AtariSTize/C64ize also your other Eye Candy
animations?
See you in Khyberspace!

But not that much... compared to the improvement I yielded when I scaled
the frames to 400 % (no interpolation!) before creating the video! Just
look at my latest releases under "Yadgar1969" on YouTube!
See you in Khyberspace!
