Absolute VCD STANDARD

[djsqueak]

I have a question regarding the absolute VCD 2.0 STANDARD - In attempts to get VCD's to play properly in my ragtag POS player, I want to get it right before I start tweaking.

I've seen both 1152 and 1150 for the bitrates. Which is it?

Which is better: NTSC 29.97 or NTSC 23.976?

Does the bitrate ABSOLUTELY have to be 224 for audio?

Thanks for all your help.

See the "What Is" section to your left

I am aware of that section, I read through everything. The only reason I asked is because I was running into playback problems on a player that I'm guessing is only capable of the ABSOLUTE standards. Additionally, the VCD standard supports two different framerates, and I wondered which was better (per se, hoping that might be where the problem lies.)

The point of this was to get a human response rather than reading a faq. Gawd.

Basic questions get basic responses, The problem is not in your framerate provided your player outputs NTSC & your TV is of NTSC variety. In theory, 23.97 has a high bit per pixel ratio which is prefered, and thus leads some to believe it has a better image quality.

Thanks. Also, if I'm not mistaken, actually finding a tv-show, movie, cartoon, or anything else (short of soap operas) that actually runs at 30fps is going to be a kind of weird occurance anyways, correct?

In this case it'd probably be a better idea to run at 24 since most nothing I'd probably end up wanting to burn would use all thirty?

Thanks again!

In general, only film sources run at 23.976 (24 technically). Most broadcast video and personal camcorder footage is at 29.97 fps native (NTSC regions, anyway).

For standard VCD, the audio bitrate can only be 224. 1150 is the standard video bitrate.

djsqueak,

For VCD 2.0 specs look here:

Almost every MPEG encoder can create a VCD spec MPEG-1 file, but most don't multiplex the file precisely to the VCD 2.0 spec. The only multiplexers I know of that will are bbMPEG and VCDMUX.
