I just discovered that Openshot is getting slower when you use pictures with high resolution.
I decreased the resolution of a lot of pictures and put these files on the timeline. Now when you change some things on the timeline there is almost no slowing down.
So a workaround could be to decrease the resolution of the pictures to the final resolution of the movie. I did this with Phatch Foto Batch Processor.
I can imagine that there is also a slowing down with high res movies but I can't test this because my camere can only handle 640 x 480 movies.
But I still hope that this problem can be solved within Openshot.

Title:
  OpenShot gets slower as you add more clips to the timeline

Status in OpenShot Video Editor:
  Fix Committed

Bug description:
  When I have about 100 JPG photo files (about 10MP) Openshot get's
  REALLY slow. Up to 10 seconds just to change the position in the
  timeline (programme gets grayed out in this time). CPU: 100%, RAM: 33%
  - so RAM is not the problem. The CPU is a Dual Core 2GHz (Intel core 2
  duo CPU T5870 @ 2GHz). Is that too slow??? I wonder because everything
  is fine with only a few files.

  Thx,
  k_s

  P.S.:
  Ubuntu karmic koala 9.10
  Openshot 1.0.0 (ppa)
