VideoStudio :: Getting AVCHD Transition (blips)?

solving the problem of brief "blips" or "jerks" following transitions in video generated by VS X2 from AVCHD clips.

Last November, I reported to Corel the problem of brief "jerks" or "blips" in AVCHD video files or hybrid discs generated by VS Pro X2 from clips created by my Sony SR11. There was a long thread here in which several Canon users stated that they had the same problem. [URL]

In addition to transitions, I also get the same blips in the video at the end of titles placed over the top of video. I am not sure whether Canon users have that problem.

Since the problem still has not been fixed, I followed up last week with Corel asking for the status of the fix for this problem. In their reply, they asked for more sample clips and asked that I post their ftp site URL where you can upload clips that will demonstrate the problem. They want clips from the various AVCHD camcorder models which are having this problem. They didn't say whether they want raw clips or VS-generated clips that contain the blip, but I suspect they want raw clips so they can try to re-create the problem on their systems.

When selecting a clip to upload, what appears to cause the problem is that at the end of a transition or title, the video jumps back one frame and then proceeds forward again. Thus two frames are repeated, which causes the "blip". You can see this by viewing the generated file frame-by-frame.

So the blip is most apparent when there is obvious, but smooth, movement in the original clip. The raw clip I sent them when I reported the problem in November was of a truck driving down a highway, moving across the screen from left to right, and was shot on a tripod to eliminate any camcorder movement. In the VS-generated video, at the end of the transition, the truck jumped backwards slightly then went forward again.

A clip containing little or no movement, or a clip that is already jerky and unsteady, will not illustrate the problem well. So please select your clip accordingly. A single object moving across the screen against a non-moving background would be ideal.

Following is the ftp site where you can upload clips.
