Comment 15 for bug 517451

I too have the "single frame flashing bug" at the beginning of transitions. I've tried making the transition longer by starting the transition sooner thinking that it just wasn't positioned right. I added up to 2 seconds as an experiment, the flash continues to stay at the beginning of transition even though the next video doesn't start for another second or two. It seams random. All the types of transitions that I use are affected, circle in to out, Big spiral, clock left to right. The flashing doesn't seam to happen in the first 20-30 min of the video. I have about 80 clips in a 2 hour video. I haven't tried the "move clips to the new track" workaround.

My input video is at 29.97 fps, 1080p AVCHD mpeg4, 24Mbps. Audio is AC3 256 kbps. It comes from a Canon Vixia hf20.

I've tried Openshot on Ubuntu 10.10, 11.10 and 12.04 beta. Flashing bug exists on all. I've recreated the project multiple times. I've tried converting the video to raw format with avconv, then creating a new project using raw video. Bug still appears. Also tried from mpeg 2.
