Atari 800XL video playback

[ Show youtube player ]

From what i could find out about this (some copy&paste) :

The "trick" is that this movie is pre-converted to an atari 8bit graphics format. It is called the GTIA mode. The GTIA mode is a cool and fast mode, allowing you to show 16 shades at one scanline. It takes not that much KB's to show one pic. With a modern HD connected (that is necessary!) & the right tool, it is possible to load and show all the pictures.The whole thing is streamed from the ide.



C64 video playback

Not to be confused with famous 1988 Digitize Design fully digital demo. This one is actually a combination of digitized animation and SID chip generated music. Frames are being streamed realtime from 1541 disk drive, and as you can see, the playback is perfect.




Spectrum video playback

From what i could find out about this (some copy&paste) :

It is a work in progress. it's not compressed video at the moment, but to get the 1200 screen$ files for the short video was step one. Still I think this is already very cool! And for you to be able to do the same I included comments so you know how I did it. Oh, one step was to create a video with the correct resolution. I used Adobe Premiere Elements for that, but it should also be possible with Virtual Dub. Anyway, now I will start programming to get the algoritms I created for compressed video working. Have fun!


PS: Sorry, this is just for the fun of it
