Yes. it's true. thanks to nezgar flashjazzcat ndary and (Phaeron Wrathchild Stephen and a8isa1 at AAge), I've finally got some video streaming done via A8.
Some things to consider:
■ 1920x1080 - always used your best quality source video
■ 160x192 - output video will be limited to Atari capabilities
■ 15KHz - audio sampling rate
■ audio volume is fairly quiet - this can be boosted in your initial video editing program. I've experimented and found that +6dB is the max should should increase the volume by - at this stage. Now re-save you original video, before proceeding to the instructions below.
■ audio can then be boosted a second time in VirtualDub - limit i have found is a a further increase of +6dB (208.9%) - above this will cause clipping and distortion.
I've cobbled together my own "Idiot's Guide" and it works well - every time now. It's not a long process. After your first subsequent runs will take about 20 mins beginning to end (for a 20 min video)
These are extremely simplified (for my own benefit) and the source info was taken from written guides by Avery and Nir, with added input/help from Jon ( flashjazzcat ) and Ryan ( nezgar).
Usual disclaimer: you do this AT YOUR OWN RISK. It's important that you proceed with caution in HxD/Win32 - ALWAYS double-check before writing to any disk!
