ixel value accordingly. For example: if the input still is 2048 x 1536, use 3 pixel value in the filter because 1536/576=2.7). The idea is to cut down on vertical resolution (excess of which causes interlace flicker on an interlaced TV) without compromising horizontal resolution. -- Matti Haveri <

Steven M. Schultz: you can use this checklist when preparing a video bit budget: Total Size of a DVD disk = 47 subtract 5% as a reserve (DVD .ifo,.bup, UDF info,) subtract audio. With 192Kb/s this works out to 144 bytes/minute. subtract the still menus, guidline is 10 bytes/m

Which XSVCD resolutions do you prefer? My current favorite is PAL/NTSC 352x576/480 with 48 kHz audio. As a legal DVD resolution and audio it _should_ be easily transferred and concatenated to DVDs later. 720x576/480 is also a legal DVD resolution but at 2500 kb/s it tends easily get blocky in

The default for vcd/svcd presets is equivalent to -S 700 -B 230 Thanks for the info. I've been wondering what the -4/5 default for mpeg2enc -B is. Some old post on the list indicated that it was 224 but it is 230 for mplex overhead, right? And the -f 4/5 default for mpeg2enc -S is 730, right?

Re: [Mjpeg-users] mplex question

mpeg2enc always introduces breaks for SVCD, you can only change the size to a very large value. So does mpeg2enc -S 650 insert break points to _both_ 650 and 730 MB points? Anyway, the only situation where one would like to use a lower setting than 730 would be if s/he wanted to burn the MPEG o
