I noticed that archive.org automatically derives .webm and .ogv files -
but unluckily of abysmal quality - if you don't already upload them.

Thus I thought it could be useful to upload smaller files, if
only to avoid people trying the practically unwatchable ones.

I prepared me a shell script to derive 720p .webm/.ogv/.mp4
via ffmpeg, so this wasn't a big deal (much less effort than
re-rendering).

So you can now, if you like, link to smaller, but still
"watchable" alternatives:

These should allow even the oldest firefoxes and less powered smart
phones to watch the video streaming, without downloading before.
