A newbie here and just started making VCDs three weeks ago.

Your KVCD GOP settings is 1,12,3,1 while the standard VCD is 1,5,2,1 ( sorry if I got the figures wrong as I'm on the road right now and can't check the exact figures).

I saw that those settings stand for I, P, B, etc. Could you explain what those letters mean? Why did standard VCD choose those figures and why did you choose yours for the GOP settings?

I'm sure you've done comparisons between those settings, which settings are better? Or what's the advantage of your settings to the standard, and vice versa? Who has better quality? file size? encoding speed? etc.

I've used your template and I liked the results. But sometimes on longer films, I want the quality to be much better so I up the CQ and make it a 2-CD. I wondered, since I had room to spare, would it be better to return to the standard VCD GOP settings or just stay put at your settings?

A lot of questins, I hope you're up to it . Thanks.

Hi Timberwolf:

The figures were chosen to enable a higher compression with the CQ mode used in TMPEG. The standard GOP structure doesn't compress as much.

Take a look here for an explanation on I, B, P frames and MPEG-1 in general: http://bmrc.berkeley.edu/frame/resea..._overview.html

You may want to try the new templates released today. They generate even higher quality than the old template, while still maintaining about the same final mpeg size.
