Video quiz

Here's a bit of movie footage taken with our shiny new camera in mid-December. In fact, it's the same bit of footage five times (except that the first one is shorter because the file format is huge). Your task, should you choose to accept it, is to find out which ones work on your computer. Note: don't take part in this task if cute baby clips are not your cup of tea…
  1. MJPEG, 823K (straight out of the camera)
  2. MPEG1, 158K
  3. MPEG2, 169K
  4. MPEG4, 178K
  5. H263+, 188K
Just for fun, there's a little animated GIF possiblynot suitable for use as a LiveJournal icon. This probably isn't very efficiently compressed and the 100K limit means it's small and quite short — there are probably better ways to make it. On edit: I ought to have read the docs first, as the LiveJournal limit is 40K, not 100K!

Note that since the server bandwidth is limited to about 64kbps it will take on average half a minute to download clips 2–5 if no one else is using the connection, and rather longer for clip 1. Don't feel obliged to download all of them, but at least try to find one that works.

So…

By the way, if anyone actually knows anything about movie encoding and has advice about bitrates and so on, do feel free to comment.
