There's still an Amiga VLabMotion & DraCo group on Yahoo:
http://groups.yahoo.com/group/amiga_vlabmotion/DraCo can run AmigaOS3.9:
http://www.cash-multimedia.com/ms5.htmlDraCo is the only Amiga device/clone/whatever that supports Firewire. It was available as an add-on board. I can use HD cameras with my DraCo. HD camera downconverts to SD, connect to DraCo via Firewire and get a very high quality image.
DraCo was expensive but so was the VideoToaster/Flyer once you added all the pieces to make it usable (Amiga box/accelerator card/TBCs/etc). DraCo & MovieShop offered much more than the Digital Broadcaster NLE. The MovieShop NLE has essentially unlimited tracks of video & audio, fx, titling, etc. MovieShop is Avid-ish. With the multi-play feature, I can play up to 6 synced clips in a window and click the ones I want as it plays in realtime, from there it creates a basic timeline with my edit decisions. It's like a virtual switcher. Great for multi-camera coverage of events.
Video partition size on DraCo isn't limited as it was on the little brother VLM. I have 180GB SCSI drives in my DraCo. Partition it large or small. I'm not sure if Toaster/Flyer had size limits.
DraCo works with USB cards & ethernet. It has a ZII bus. The other expansion bus is the custom DraCo bus, which is faster than Z3, but only supported by MacroSystems custom DraCo cards.
I have used multiple display cards on my DraCo with CyberGraphX. I can have MovieShop on one monitor and Monument Designer open on a 2nd monitor.
If I render something more complicated on my Mac, I can export a JPG stream of images to an ISO9660 DVD and then read that on my DraCo into MovieShop.
The DraCo Cube is slightly faster than the Tower version.
AmigaOS 4 is sadly missing video editing capabilities. Even a direct port of MovieShop to OS4, without any new features, would be a big improvement and enticement for running OS4. You'd have to work a way around the custom hardware though.
