Hi guys, in recent months I got back into actually doing something with my Amiga again. First, I ripped out this old green battery and after I had assembled the whole thing again, I got into a conversation with a friend about the capabilities of the Amiga. So I came up with the idea having the Amiga show a video of about 3-4 mins on an HD flat screen in exactly the same way as a PC does in full screen mode (in 16:9 format); in principle, that should be possible (I guessed
Looking around on youtube I found some converted videos playing on an Amiga, but all with lots of conversion artifacts, or just very short.
My goal became to create a HAM8 video where each frame has its own color palette and a *very* small (if at all) number of artifacts. Finally I found one tool, released in 2015, that gives excellent HAM8 results whereas other tools have some disadvantages:
* ppmtoilbm: generates a fixed grey palette. The result is to get several conversion artefacts.
* avi4hv doesn't generate separate palettes either. The player is well done (and fast), but the converted frames have lots of artifacts (didn't try avi4aga yet, but I guess it doesn't create different color palettes either?).
The best HAM8 converter I found is png2ilbm. It was released 2014/15 and generates really good HAM8 pictures:

My procedure was to decode it with ffmpeg into separate frames (=files), convert each frame to HAM8, and use the Amiga tool animconvert to put it into one anim file again.
Finally, I came up with a 3min video playing at 25 FPS (320x251) with a very small number of artifacts. Even text (black on an almost white wall) displays well in the presence of other colors.
The final video (with added original music) can be seen here:

PS: I havent't tried AnimFX and Wavetracer yet (just learned about them some days ago). I'd be interested if anybody knows if they generate separate color palettes and what the HAM8 quality is (in comparison to the original video).
