VCD NTSC 352x240
    PAL 352x288

Audio: MP2, 44100 Hz, 224 kBits/s, stereo
Video: MPEG-1, 1152 kBits/s CBR


SVCD NTSC 480x480		should be when fps 29..
     PAL 480x576		should be when fps 23..

NTSC FPS = 29.970, 23.976       30 also ?

PAL FPS = 25.000

Audio: MP2, 44100 Hz, 32-384 kBits/s, stereo
Video: MPEG-2, up to 2600 kBits/s VBR

(audio rate to use 224 or 160 ?)


From transcode docs:

- For NTSC material, transcode currently generates film mode, i.e., 23.976 fps
(progressive) for most NTSC DVD sources. For generating NTSC MPEG video, the
final result should be played at 29.97 fps. Therefore the encoder must set the
appropriate flags to force a decoder/player to generate a 3:2 pulldown
(telecine) on demand. Transcode offers a long option "--pulldown" to encode to
MPEG video with the appropriate flags set and switching the display rate from
23.976 to 29.97 fps.

(VCD)
- Replace "-Z 352x288" by "-B" if you prefer the fast resizing mode by
transcode. Example: reduce 720x576 to 352x288 with "-B 18,23,16".
