how they make commercial VCD's

[clickit]

hi to all,
i have a very simple question to ask

my napa dav311 play my home-made vcd's with hickups, cuts in playback,
but it plays commercial vcd's fine !
i'm using vdub(latest version) frameserver to tmpeg(latest version), or to panasonic mpeg1 v2.51 but the results are the same (shitty...)

and the question is : how the commercial vcd's are created ???

thanks in advance

they are stamped from a mother disk and the alum substrate is sandwiched between some plastic. ...

ok -- software wise ... a tape (ussually d-beta or beta sp or sx or any of the new digital formats) is made up of the the whole program and encoded by a hardware encoder OR it is made from a bootleg screener/dvd/ts/tc same as everyone else ... depending on where its from OR a DLT or exabyte tape is sent out and frame encoded either by software or hardware.

if the film doesnt exist yet in digital form (nowdays rare) it (the negitive) is scanned (if its gong to be a good job - but expensive) or telisync dub is made of the film (pretty cheap, but expensive equipment still - different from TS you download) - that scan or TS is put on tape (TS) or frames on DLT (scanning) ..

If your VCD's are cutting out in playback, or they're jerky, then I might suggest that you are not making compliant VCD's. Jerky playback, audio problems, colored macroblocks, etc, can all be symptoms of an xVCD.

Are you using the standard VCD template in TMPGenc?

Search the forums on the NAPA. This little unit has been plagued with a number of problems and some people have seem to have found some solutions.

From memory, I recall it being written that encoding the video at a slightly reduced bitrate (e.g., 1120 kbit/s) may improve the playback...

Try using the Panasonic MPEG1 encoder instead of TMPGenc for your VCD's. I have a portable player too and it would hiccup every second on any MPEG1 file that wasn't created by either DVDx (shite quality) or the Panasonic encoder.
