Silly Beginner question...
Yes, some software pre-****yses mpeg files, others dive right
in. If the file is too large for the software it probably won't
know, you'd have to wait for it to go thru what it thinks the
file size is before finding out!!! One program I use for video
has a 4 gig limitation, but displays the incorrect file size so
that it's obvious. However, it attempts to operate, if asked.
The H-250 capture card/software which I'm using can produce DVD
compliant MPEG2/MP2 files. With these I could just run them
thru DVD Lab for authoring (I don't use Ulead, tho its crippled
version did come with some gizmo I once bought) or I could play
them without authoring on the LiteOn 2001 stand-alone player.
In the latter case I'd need to split up any file larger than 2
gig, as that's the only DVD format the LiteOn will deal with.
The Hauppauge software includes nanoPEG Editor, a very simple
and fast cutter. It checks for the presence of the capture card
as a piracy measure. Alternatively, TMPGEnc has a set of MPEG
tools which includes a cut/merge program. This is by no means a
fast program, as it passes the entire file up to the cut point
for each video cut, again for each audio cut, and again when
"remuxing"
The programs which handle these large video files really need
several disk drives available to perform well. At the very
least, an authoring program has to wrap the a/v into a VOB
shell, effectively duplicating the file and adding to it. The
disc head action for this, while also attending to regular OS
demands and any other thing the user might feel inclined to ask
of the system, is extraordinary. Personally, I keep video off
of the OS drive and edit onto other non-OS drives. You can hear
the difference and the result is faster processing.
So, once again, if you intend to make a DVD, you're going to
have to pass the mpeg file thru Ulead. I'd suggest that you
make a small file, 5 minutes of video or less, and test the
whole procedure before diving in with your large file. If your
capture card allows you to select bit rates, experiment to what
different settings produce for you. And by all means see if
your DVD player will play MPEG directly without authoring.
Once you know what quality settings and file sizes work for you,
don't be afraid to hit the stop or pause button on the VCR so
that you can make smaller files. At the settings I'm using, I
get slightly more than 2 gig of MPEG2 every 30 minutes.
