Well for now I decided to continue with this great format since is
compatible with a lot of platforms for "Atari ST to Sega Dreamcast"
including PC's "unix to mac".
So I just found a way to get a lot of people to view my anymations without
problems of compatiblity isues or speed isues but what I whould like to know is
what type of quality are these bit rate settings?
Data rate:
----------
Profile nmae : Byte rate : Bit rate :
--------------:------------:-----------:
MPEG-1 : 140 kbytes : 1125 kbits:
--------------:------------:-----------:
28Kbits modem : 3 kbytes : 28 kbits:
--------------:------------:-----------:
300Kbytes CDx2: 300 kbytes : 2400 kbits:
----------------------------------------
600Kbytes CDx4: 600 kbytes : 4800 kbits:
----------------------------------------
now I need to have an idea of quality so tell me what bit rate is near vhs, dvd.
I hope some understands what I'm asking.
