If I bought a PPC card and placed it on the trap door of the Amiga 1200 would I be able to run workbench OS 3.5 on it, run Riva on it and use the power of the PPC card to watch videos or I must own OS 4.0 and run Riva on OS 4.0?
RiVA does not run on PPC for that you use Frogger (NG?) or MPlayer DVPlayer (From the RiVA guy) or something. I don't know. I don't have PPC classic.
Piru is absolutely right to some extent. Trying to play modern videos 24FPS on your classic (even PPC ) hardware is going to not be anything other than frustration. Modern PCs have all sorts of stuff like color conversion and hardware motion compensation built into the video hardware. The amiga has to try to do all that stuff in software and in the case of AGA, convert it to HAM8 format... on a 50mhz CPU....
I almost forgot the best part. You cant SEEK or even PAUSE. Once you hit PLAY it just goes. I just break all my videos into 100MB parts
On the other hand, I have converted all of the video content from Amiga Forever, other Amiga and related Commodore stuff to MPEG1 (tuned for RIVA) on my 1200 where I have a video partition for that sort of stuff. Its pretty neat watching that stuff real time in HAM8 on the 1200 even if it is a bit choppy. Stuff with bright colors like sitcoms and animations look amazingly good. If you happen to find any old Video CDs it will play those. Star Trek Generations looked good video quality wise, but the movie was disappointing.
I think the application for $15 is probably worth it.
