vcd better quality than svcd ?

[bambam]

If i create a VCD with a mpg with a very high bitrate
and i create the same movie on a svcd with a lower bitrate

Is it possible that the vcd will be a movie with better quality that the svcd ?

I have found that if you create a VCD and a SVCD with the same bitrate, the VCD is better quality. Why ? Because VCD is using say 1500kbps on a 352x288 screen whereas SVCD has to cover 720x576. TV can blow up 352x288 very well and I guarantee it will result in a better picture.

It depends on several things like: What is the quality and resolution of the source? Exactly what sort of bitrates are we talking about?

A bit-starved SVCD (say 1400 Kbps or lower) is terrible and a VCD at that rate could be better looking. Now say you go up to 1900 or higher, an SVCD will be much better than a VCD at that rate. That assumes a good quality source with a resolution nearer to SVCD (480x480) than VCD (352x240).

This is a point many people get confused about. Here's the bottomline, SVCD is superior to VCD. HOWEVER, what most people are asking about is xVCD vs xSVCD (ie. non-standard).

At the same bitrate and resolution MPEG1 looks the same as MPEG2. So if you encode a 352x480 2000kbit/s video to MPEG1 and author as an xVCD, or to MPEG2 and author as an xSVCD/xCVD, the quaility will be the same.

It use to be that a lot of people would recommend making xVCDs as they were more supported by most standalones. These days it's a little more hit and miss, but still generally true.

Another thing to consider is that MPEG1 doesn't supported interlaced source material.
