Time-lapse and WebM test

You'll need a browser with at least native WebM support to view this video, like Firefox, Chrome, or Opera. Read more on WebM support here.

The workflow for creating this was:

  1. Use Magic Lantern intervalometer to take 10s exposure every 10s. Left this going for about 20 minutes until I lost my game of 2048
  2. Import raw sequence into After Effects for colour grading and render
  3. Converted video to WebM with ffmpeg: ffmpeg -i input.avi -c:v libvpx -crf 4 -b:v 15000K out.webm

15000K being your bitrate, and -crf being quality from 4 (best) to 26.


  • There's a random all blue frame part way through the video. Not sure how that happened, but it's something I'll have to screen for in the future
  • At 24 fps, I only got a few seconds of video from 20 minutes of shooting. Be more patient!
  • Drastic changes in lighting are distracting when you can't see the whole landscape

On the whole though, I like the result and I'll have to try this more often.
