[game_preservation] Game preservation videos?

[Andrew Armstrong]

Okay, but they'd be huge files. MPEG-2 isn't exactly very resourceful 
with its lossy quality (ie; with a high bitrate, it still can look dodgy 
with high motion, and problematically can chug old computers even though 
it uses low CPU, it'd be a lot of disk usage :-) ).

I only know about TV-related MPEG sizes, so good to know the format 
isn't set - however, didn't you say the aspect ratio was set on the 
Archive.org? Thus the entire point? I will need to research myself 
instead of blabbering on, sorry.

This means that a second MPEG-2 file could be available of the 
"original" which was the full aspect ratio + pixels + high bitrate + 
original FPS. This might be in fact *smaller* then a 4:3 aspect ratio 
standard TV sized MPEG file of course (handhelds for instance).

Hope that made sense, and that perhaps it would be something worthwhile 
in any video archive, one copy for "easy viewing" and one at the 
original, very high quality, original.
