VirtualDub Deshaker

I ran a 30 minute clip (old film and jerky) using the default settings suggested by Johnmeyer and it did work much better than my last experimental job. The only bad thing I noticed was the sometimes movement of different objects in the scene in relationship to the other objects like it was being shaken in a container. I thought about it for a while and used it anyway after viewing the color special on PBS of WWII which did the same thing so I figured they used Deshaker on that one too. What settings would ensure that this does not happen?

Are you using this on movies captured from TV? You need to Inverse Telecine (IVTC) those first, if you are going to do any sort of frame-by-frame processing, you must ALWAYS IVTC the video first.

All bets are off if you try to process telecined film without first doing IVTC.

If you are NOT working on film that has been telecined onto videotape, than you might try reducing the block size (down to 15). You can also try the Ignore Image Area (as strongly suggested in the guide) to ignore motion NOT caused by camera movement. Finally, you can try changing the "Discard motion of blocks that have a match value <" setting. The default is 300. Try doubling it. If that doesn't help, try cutting it in half. Select short clips (10-15 seconds in length) so you can do these tests quickly.

Thanks, I mispelled your name and I will correct that. The stuff that I
had the real trouble with was the the stuff I got back from the pro lab.
