None of the videos are lossless.
The later ones (labeled HQ) have a 2x upscaling with nearest neighbour. It make things look much crisper. But it's still H.264 encoding.
Lots of the dumps from Hatari I have in lossless (PNG) format. There are however no hardware acceleration for PNG. There is also no web-player for PNG encoded movies. And last, the files often have five times higher bitrate than the 2.5 Mbit/s H.264 used now. And I don't have the space to store yet another version of the files. I really can't ask more from Untergrund.net, who already hosts some 30-40 GB of files for me.
Perhaps I'll add lossless as download in the future when space/bandwidth isn't an issue.
Oh and one thing more; even my 2.4 GHz SandyBridge Core i7 Quad-core CPU struggles to depack PNG 800x544 at 50 FPS. It works for the most time, but certain parts can cause framedrops.
