I have previously used avidemux to tag the commercials and crunch
the video. It's been a painstaking process, but have a scripty that
pretty much does it automatically given a list. Something like this:
FILTFILE=filters
VIDCONF="2pass=658"
VIDOPTS="--filters $FILTFILE --video-process --halfd1-res --video-codec \
DVD --video-conf $VIDCONF"
avidemux2 --load $i $VIDOPTS --save-raw-audio $base.m2a --save $base.m2v --quit
mplex -O 3003mpt -o $base.mpg -f 8 $base.m2v $base.m2a
Where filters contains the xml on my filter choice from avidemux:
<?xml version="1.0"?>
<filters FilterNumber="1">
<Filter Tag="39" Conf=" MPlayer HQ Denoise 3D (4.0 - 3.0 - 6.0)'">
<Parameters Number="3">
<param1>4.000000</param1>
<param2>3.000000</param2>
<param3>6.000000</param3>
</Parameters>
</Filter>
</filters>
i.e. Mplayer HQ Denoise 3D (default parameters)
The resulting process takes about 4hours/hour on a 2.4Ghz P4 or
Athlon 2400. I've got 2 SMP boxes, so I can run it 4 times and get 1
hour/hour aggregate.
