Does anyone know which file (if any) that makes a video file on a video CD a video CD as opposed to just a ROM with a vid file on it?

Is it something like an ini file or is it a codec that the vid file is encapsulated in? Thanks in advance!

I believe the disc structure and MPEG file formatting is what makes a VCD compliant. Like the DVD disc structure (VIDEO_TS and AUDIO_TS) there is a specific structure that makes up a VideoCD.

Google 'vcd structure' and you should get some useful links to the structure and encoding of VCD compliant files.

I believe Philips is the owner of the format as well as the SVCD format. It comes down to how the disc is structured and I beleive it is MPEG-1 video as well as only 1 MPEG audio track. It's been a long time so I'd recommend visiting the Philips website and looking up the specification.

mpeg1 vcd compliant files are 1150kbps for video and 224kbps for audio. as to the structure, the mpeg file has a .dat extension to it.
The structure of the CD will contain the following directories and files:
CDI
CDI_IMAG.RTF
CDI_TEXT.FNT
CDI_VCD.APP
CDI_VCD.CFG
EXT
LOT_X.VCD
PSD_X.VCD
SCANDATA.DAT
MPEGAV
AVSEQ01.DAT this is the actual mpeg1 file
PICTURES
SEGMENT
VCD
ENTRIES.VCD
INFO.VCD
LOT.VCD
PSD.VCD


Hope that helps
