Scripting and Reverse Engineering / Re: FF7 - Technical Discussion on Game Resolution and FMV

Well that was just rude and totally uncalled for. I went to the trouble of registering for this site and writing a post just to help you guys. I had a meaningful contribution about something which the original posts seem to have missed. And all I get is a rude response that I shouldn't have posted.

The "rules" I could find say that old posts are okay if it's relevant. It's easy enough to automatically close threads if you don't want anyone posting.

Why don't you just close the forum and move to a private mailing list if you don't want anyone else contributing?

It's probably overscan. Analog signals were designed to cut off a number of lines from the image. This is where analog TV signals could dump all their garbage. Thing is with computer generated video signals like on consoles there is no garbage to worry about. But because TV's would cut it off anyway you had to accommodate for it if you wanted your full frame to be displayed. Otherwise you'd just be wasting pixels.

Broadcasters gave out recommendations of 5% overscan. And 95% of the half-resolution of 240 is 228. Round down to the nearest multiple of 8 (common in many video codecs) and you get 224.

For the high-res renders I'm guessing they wanted to keep it at the same aspect ratio. Another hypothesis would be that their rendering engine didn't give satisfactory results for low resolutions and they decided to render high-res and do some smart downscaling.
