-graphic board with CyberGraphX (eg. CyberVision64, Picasso II, Retina, etc)
or AGA chipset
-2MB of FastRAM, 512K of ChipRAM
software requirements
-CyberGraphX 2.21 or higher (if used with a graphic board)
-asyncio.library V39 (included)
-garbagecollector.library V3 (included)
recommended hardware requirements:

Changes since V1.2:
- again some fixes for elst data. Who invented this bullshit? :(
- fixed bug introduced in V1.2 that caused CyberQT to play some animations
with maximum speed instead of normal speed. Thanks to Thomas Wenzel for
reporting this.
- IMA stereo decoder was completely broken and caused immediate crashes.
This is fixed now.
- dithering is now available for all truecolor encodings and looks much
better than before
- implemented automatic resampling of audio data, if frequency is >27kHz and
no double scanned video mode is available
- optimizied skipping detection. CyberQT now skips less often than before and
produces more smooth playback.
- audio-only QTs are now played correctly
- skipping is now (hopefully) perfect and never activated if there is no need
to skip
- some more optimizations for skipping detection
- complete reworte timing calculation. garbagecollector.library is required
now.
- added support for stereo audio splitted into two mono streams
- displaying colormapped animations (8bit or less) on public truecolor
screens is now possible with CyberGraphX 3 (rev 41.9 and up). Much thanks
to Frank Mariak to implement this function for me :)
- hopefully last chnages on elst-chunk calculations. All my "problem-movies"
are now played 99.99% in time.
- added very simple support for edits to be played multiple times. Currently
only one frame is supported.
- very small audio frames are now merged to larger ones if possible to avoid
unnecessary overhead on audio.device
- finally managed to implement JPEG decoding. I can't explain why it didn't
work before. But be warned: it is DAMN slow. You need at least an
MC68060/50 for nearly smooth playback!
- fixed problems with elst data for audio tracks. Only elst data for video
tracks where handled before.
- very much thanks to Thomas Wenzel for burning a CD for me. Unfortunately he
renamed the ".resource" directory to "resource", so this is now possible
for resource forks, too :)
- some small optimizations
