I'm making a cross platform CD-ROM with several video files
in mpeg-1 format on it. It all works fine on the Mac, but windows
takes an age to pre load the video clips before it can play them
(works fine from the hard drive, but takes several seconds from
CD-ROM). Also when running from a CD-ROM on PC, the fast forward
and rewind functions don't work correctly from CD on PC (they
appear to pause until you release the button whereupon the video
suddenly jumps forward or backward)
Is this just down to the way that Windows deals with MPEG-1
or does anyone have any tips that could fix this?
Mpeg-1 has to be the format used, as no third party software
can be needed on the users machine (so windows media, real and
quicktime specific formats are out).
Are you using any Xtras? I've used MPEG-1 a lot on CDs for
the same reason as you -
an all purpose format that works on Macs, PCs and has little
for end users. i use the MPEG Advanced Xtra which is very
good, is cross platform
and doesn't require additional software when the Xtra is
bundled with the
I have run unto a few problems with MPEG not playing
smoothly. There are quite a
few technotes on the MPEG Xtra site that I've found helpful.
One issue I came
across was that there was an audio and/video problem that is
sometimes created with
Cleaner or other encoders. I use TMPGEnc for all my Windows
MPEG-! encoding as it
gives great resells.
Anyway, tell me more about your problem, if you are using an
Xtra and maybe can
help further if what I've said hasn't already.
I'm using MpegAdvance. The videos are supplied to use from a
production company. I'll ask them if they're using cleaner - I know
the use final cut and so mostly I think they use Compressor for
this stuff. But I'll check.
