Could someone please tell me why the saturn has such troubles with fmv? It's grainy, low res and choppy. The psx and sat came out at the same time so why is psx's fmv so superior? I always wondered since I bought a saturn...
Not necessarily true. It depends what type of footage you are compressing (i.e. CG vs "live" footage). You can also assign a higher or lower data rate to the video depending on how much space you are willing to give up for audio too.Quote: from Raijin Z on 4:03 pm on Mar. 10, 2002
Lemme break it down, as I see it.
ONE: Cinepak compression appears to leave more artifacts than MPEG would when compressing the same source.
Firstly, you negate the first sentance with the second. Of course the filesize will be larger with a more inefficient codec. Secondly, what 'more recent' codecs are you comparing to? The PSX and Saturn came out at around the same time, so the technology available was the same.TWO: Cinepak compression is inefficient compared to more recent codecs. For as crappy as the video is, the filesize should be smaller. Not Sega's fault though.
[/quote]THREE: Saturn doesn't have a great abundance of working RAM to play with. Streaming high quality video with a 2X drive to compensate for such little available memory would be iffy.
Actually, from what I've heard the format is proprietary, and is closer to MJPEG than MPEG.PSX has Mpeg encoding.
Are you sure about this? I've heard of specific regions getting a version of PSX that can play VCD, but AFAIK it was never part of the base console otherwise.The first PSX's could play VCDs.Too bad they didn't keep the feature.
