Streaming Video on Your A8

Video streaming done via A8


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!
