Title:
  Video files from Canon DSLRs have artifacts

Status in OpenShot Video Editor:
  New

Bug description:
  I have video files shot with Canon EOS 60D. They display flawlessly
  when played back with MPlayer, Totem, etc. However in Openshot they
  have massive visual artifacts. These are visible both in the preview
  window as well as in the final exported video.

  I'll attach one small sample file to demonstrate the issue. To test,
  just create a new project, add the file to the timeline and play.

  Tested on Ubuntu 12/04 current beta.
