"Idiot's Guide" to convert videos for streaming them on the 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!
