People,

I am using Xmpeg 4.5 -> Videoserver 0.93 -> CCE 2.64 to create SVCDS. I have heard that if you crop the picture in Xmpeg and then letterbox it you can allocate more bitrate for the actual picture and instead of wasting it on the black bands.

The problem is that the only examples of which numbers to use that I have seen so far are for NTSC and I need the numbers for PAL (going from 720 x 576 DVD to 480 x 576 SVCD). Other things which may be useful - I have a 4:3 tv and am using a standalone player to watch the SVCD's on. I also read that this is only useful when converting widescreen movies, is this true (because there is no black bands on a 4:3 movie) ?

Kind Regards.

TheNSA...

The black bands are not a waste, they actually compress really well giving more bitrate to the picture section, however the resolution of the picture is reduced. It really depends on how it looks afterwards (i usually leave bands in for vcd and out for SVCD). Your right about only being for widescreen. I wish I could tell you the numbers but I don't use Xmpeg.
