I wrote a duplicate to this bug (sort of, mine differs as I'll explain)
because, as it stands, with OpenShot 1.2.2, OpenShot becomes completely
unusable after 2 or three tracks, especially when layered, have effects,
or have their time stretched (slow motion) or compressed (sped up). My
bug specifically deals with the PLAYBACK of OpenShot. If you're testing
an edit, I need to be able to see in _real time_ how it looks. When I do
playback on anything more than one track, it slows down and gets choppy.
The more tracks, the more choppy it gets.

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)
