Will CBR of 2,000 will give you...

[Treebeard]

the same file size for both a mpeg1 & mpeg2?

Using the bitrate calculators it seams that if you use a cbr of 2000 for vcd you can get approx 50 min of video, now using a cbr of 2000 for svcd you can get approx 50 min of video. Is this correct or am i missing something.
If its true why would you ever want to make vcd? when same amount of minutes can be used for Svcd.

I guess im actually talking about xvcd & xsvcd but my question still applies? svcd is by far superior so why not use it if the same amount of minutes fits on the cd as vcd

You are correct. Bitrate is just that...rate of bits. The same rate for the same period of time give the samte total of bits, provided audio is the same bitrate. The reason many people prefer mpeg1 like vcd is compatibility. It is compatible with a majority of home DVD players and mpeg1 is compatible with Windows Media Player without any additional codecs. SVCD is far less compatible with home players, but I agree the quality is far superior.

Same bitrate spec for MPG-1 and MPG-2 WILL give the same size file, and equivalent quality if all other parameters are the same.

HOWEVER, this may not be true for VCD and SVCD, which while being MPG1 and MPG2, constitute SPECIFIC RESOLUTIONS within those MPG types.

A CBR of 2000 is probably more than enough for a 352x240 file, and especially if you use VBR encoding the average would probably fall below that as such a bitrate may not be necessary. For a 480x480 file, a 2000 average or CBR bitrate may NOT be sufficient to ensure an absence of pixelation, and a higher bitrate, and therefore larger filesize and fewer minutes per disk, could be necessary.
