how many MB does it take to put Subtitles on a VCD or a SVCD

[Beautiful Alone]

just wondering..

Compliant VCD is CBR, 1150kbps, so an hour or black screen and an hour of action scene, it's all the same file size. SVCD (if VBR) will vary a bit.

VCD's only support hard encoded subs, basically the subs are physically a part of the picture so it doesnt take up any additional space on the disk.

The same applies to SVCD's if you use hard encoded subs as well. But SVCDS also support up to 4 soft encoded subtitle streams. The size that each stream takes up on the disk depends on how many individual subtitles there are in the stream. You can use FitCD to calculate how much space your sub streams will take up.

Soft encoded subtitles hardly take up any room at all. With four streams it adds 2, maybe 3 MB's onto the mpg's filesize.

One thing that you need to pay attention to is your max bitrate because the subtitles are included in this. I'm not sure exactly how much bitrate these add but I have read its around 500kbits, though that seems high to me. The total max bitrate allowed in the SVCD standard is 2778kbits, and that includes Video, Audio, Subs, and multiplexing overhead, so always take this into account when making SVCDS.
