Currently we don't generate a .webm movie for captures of greater than 100fps, due to limitations of ffmpeg (it errors out when you try to do this). This is sad, and makes it harder to debug problems for high speed captures. We might want to switch to using vpxenc for this, which not only has no problem with higher frames per second, but also seems to generate much higher quality results. Howto on creating a webm from a set of pngs using vpxenc: http://wiki.webmproject.org/howtos/convert-png-frames-to-webm-video

Resolved this by capping the playback rate of generated videos at 60fps, see bug 964814. vpxenc does indeed generate higher quality results, but it's slower to encode. I think we should probably just leave things as they are for now.
