Hi KH!
I have a question. And no, it's not a shrink type rhetorical, to which
I already know the answer, thingie. :-)
Just what is Mpeg4?
It seems that MS has at lease one version of it, and so does Apple. I
read somewhere that DivX, and it's clones, are also Mpeg4 variants.
Am I wrong, or am I just confused?
Or, am I wrong AND confused? :-/
Of course, if we really want to get into confusionizing, we can try to
discuss the "H" series HD codecs that I have only seen in my software
settings and haven't a clue about. :-(
When it comes to codecs and players, Windows has the advantage over the
Mac. Apple wants it's codecs to be cross-platform, and MS doesn't.
Also, video has always been part of the Mac OS, since that capability
was introduced, which limits what third party players can do, whereas
on the PC, video has always been an add-on, and other players aren't
limited by the OS.
While the Mac is the small computing platform of choice for video
production, because of the combination of OS and great software from
Apple, it still has problems with playing any videos that aren't
perfect, and that use odd "foreign" codecs.
A note about "Adrian":
Mac users may have some difficulty in joining the parts. We can't use
JAS, and Mac file joiners may not see the parts in the same order as
they are seen in Windows, because Apple places ASCII characters in a
different priority order than does the PC.
This is why, when I post large movies, I use larger split sizes, so I
won't go over 999 parts. Or bottles of beer on the wall? :-)
Take care,
