When I rip DV AVIs from my camcorder and then process with AVC encoder to make MP4s, I get really bad camera shake jitter, far more visible than in the original AVI. This happens whether I deinterlace or I process interlaced.
I think it might be a motion estimation and compression problem. Are there h264 settings?
I've seen in my MP4s that it does a good job (too good a job) of freezing the background frame and only encoding things that are strongly moving. For instance stepping forward or backward frame by frame, a kid's arm will move, but the scene doesn't shift a single pixel even though it's a handheld. Even a balloon which has been batted might be frozen for two fields in a row if it's moving slow enough, even though it's clearly moving 'in real life'.
I think this is what is causing the exaggerated jitter due to camera shake. The frame will be frozen for multiple fields and then jump.
Is this fixed by dialing a number in motion estimation, or by lowering max GOP?
Thanks for any insight!
