Interesting read about Amiga & video etc:
http://tech-head.com/amiga2.htmbounties and news about getting Amiga video editing going again:
http://www.discreetfx.com/press.htmland for example:
Chicago, Illinois – November 30th, 2007
Now that Amiga OS 4.0 is available for Classic Amiga, Visual FX company DiscreetFX LLC Inc., is willing to work with select members of the Amiga OS 4.0 development team to insure future compatibility with the Video Toaster 4000 card. This includes free Video Toaster 4000 cards to members of the team that have Amiga 4000/T computers running Amiga OS 4.0 and have an available video slot.
DiscreetFX's CEO stated:
"It's great news that Amiga OS 4.0 is now available for Classic Amiga's with PPC cards. What would be even more exciting is if the Amiga Video Toaster 4000 also worked on OS 4.0." The time is at hand for the Amiga to reemerge as a video editing/desktop video platform. The release of the Amiga Video Toaster source code was step one. Amiga OS 4.0 for Classic Amiga was step two. Now lets go on to step three."
and I think there has been digital video editor under development for MOS, but I did not spot any link to that now ...
