Slow playback performance with multiple simultaneous 720p video clips

[pedroo]

Binary package hint: pitivi

I am trying to edit 720p mov video footage in Pitivi (1.13.5), and when I place 1 clip in the timeline it plays fine in realtime. The problem begins when I add another clip and try to edit. Besides the 1st clip (that continues to run in realtime), all the other clips or cuts are choppy. I currently have 3gigs of ram and an Intel duo core processor. And using Ubuntu 10.10. Is there something I can try?

Thank you very much!

This is a performance bug in Pitivi or gnonlin or gstreamer, but I wouldn't know exactly which one.

Of course, any help in investigating/solving these issues is welcome :)
