Cutting commercials without expensive transcoding
|
|
Hi,
I'm no video expert, so maybe I misunderstand the problem. Or maybe I'm
missing a simple answer that's already there.
I have a PVR250, so my .nuv files are mpeg2 with video and audio
multiplexed in them. After I've marked the commercials (i.e., started
with myth's guesses and tweaked them using the built-in cut editor), I'd
like to do two things:
1. Remove the dreaded commercials in order to shrink the file.
and optionally
2. convert to a plain mpeg2 for use in burning a DVD. (The issue here
may be my poor DVD authoring s/w. mplayer plays the unmolested .nuv
files. OTOH, mplayer will play almost anything.)
I've tried using various methods to accomplish #1: the built-in
transcoding (press 'x'), nuvexport, etc. The problem with all of them
is that they do time-consuming transcoding.
I don't want to change the bit rate or the format, I just want to lift
the parts that have the actual program, leaving behind the ads. It
seems that that should take, in theory, about as much time as it takes
to read the parts of the original file that I care about and write them
out. No serious computation, though maybe a bit of knitting around the
edges.
So,
a. Am I missing something that this makes this far more computationally
intensive than I think?
b. Am I missing an existing tool that does what I want?
Thanks,
Len
