Hey, First of all, I'm just curious about this. Slowly leaning as it happens but time is scarce, even to be here.
I was wondering if it's possible to have a video stream of 8bit constantly being written to chipram. Talking about realtime here, so it would have to be 640 x 480 x 8bits x 24frames /(8bitsx1024bytes) Kilobytes per second. This gives more or less 7.x MB/S. I've checked some benchmarks on the net but the very few ones I found have an average writte speed to chipram of about 6MB/s in high end Amigas. Actually some of them have more than 7 but that's probably not in 640x480. This mode probably slows dow things more so it's not possible. Well shame isn't it. I know some video progs work by just writting in the necessary info (just the different bits), but uncompressed would be more cooler.
I think if you try it... you will find this really isn't possible... From my own experience anyway.
I suggest you look at a GFX card for such activities...
