Does anybody know of a program that lets you correct motion-induced shearing that appears in video framegrabs? --You know how a moving object on video, gets sliced up due to interlacing? One field shows half the raster lines, and the next field (created 1/30th of a second later in NTSC, 1/25th in PAL) shows the subject moved over a little bit farther. The result looks like crud. Sometimes it looks blurry, other times it's all zippery. I know the AGA-Toaster had great software to deal with this but I don't have a Toaster so I need help in finding software to do this simple correction. I don't even know if the Toaster software would run (at all) without a Toaster being installed. I've seen such a prog on the older Macs. The Amiga, with it's raster coprocessor would be ideal for realtime preview of fine-tuning of such images (though most programmers don't seem to understand the Amiga's novel hardware). BTW the framegrabs are being done on a (ick) DraCo Casablanca. It's a castrated Amiga AFAIK. The Casablanca is, in this case, networked to a Wintel box, so I can use Wintel software if you have any de-shearers to suggest. If you can cc: a reply to me that would help a lot.
