I thought I would render a flyby animation of my povray tips example scene.

http://www.youtube.com/watch?v=kImPDDZkIpw

  (The original video plays completely smoothly, but for some reason that
youtube video has some jerkiness in it. I wonder if it's simply the flash
player which is choking on it, or whether youtube did something to the
video...)

Very nice demonstration.  Cubic splines for camera parameters?

I had similar hiccups show up when posting to youtube, then read 
somewhere that they re-encode videos to 25 fps.  When I switched to 
encoding the source at 25 fps (instead of 24), that source of jerkiness 
went away.

  The video is 25fps.

The youtube video for me jerks at about 0:08. If I then click it back to 
0:04, it doesn't jerk again. I take this to mean Flash is doing a GC or some 
such. If it doesn't jerk the same place every time, it isn't in the video 
itself.
