I have a DVD movie, that needs to be edited: video and sound.
Thus the question is: what software i should use to unpack from its
format to the format that will be operable for the video audio
processing as the next step?
Finally, i want to compile it in DVD format again. So, it will be nice
to loose its quality minimally. Big thanks, for Your solutions!
Funny, it has been discussed a couple of times since your original post
but in different threads.
This was from a thread on copying a DVD.
Here is a script I use for shrinking DVDs. Needs some work but you
should get the idea. You will need to d'load vobcopy, tcextract etc.
Using the tools mentioned and Audacity and avidemux2 or similar
programs, you should be in business.
I have installed yumextender and this allows me to search through the
various packages that are on the reposotiries that I use. It makes it
easier to browse the various and numerious packages that are available.
Basically, you have to convert the DVD vob files to a format that you
can edit.
#! /bin/bash
cd /video
pwd
echo "Ripping DVD"
vobcopy -l /dev/hda -t movie
echo "Extracting Video"
tcextract -i movie*-1.vob -t vob -x mpeg2 > movie.m2v
echo "Extracting Audio"
tcextract -i movie*-1.vob -t vob -x ac3 -a 0 > movie.ac3
echo "Calculating Shrink Ratio"
rm movie*-1.vob
echo "Calculating Shrink Ratio"
M1=$(ls -l movie.m2v | awk '{ print $5 }')
M2=$(ls -l movie.ac3 | awk '{ print $5 }')
M3=$(echo 4600000000 - $M2 | bc)
M4=$(echo "scale = 2; $M1 / $M3 * 1.04" | bc)
echo "Movie size =" $M1
echo "Sound size =" $M2
echo "Blank - Sound size =" $M3
echo "Scale Factor =" $M4
echo "Shrinking For DVD-5"
tcrequant -i movie.m2v -o shrink.m2v -f $M4
echo "Deleting Video File"
rm movie.m2v
echo "Re-combining Video and Audio"
mplex -f 8 -o movie%d.mpg shrink.m2v movie.ac3
echo "Deleting Video File"
rm shrink.m2v
echo "Deleting Audio File"
rm movie.ac3
echo "Authoring DVD..."
dvdauthor -o output -x dvd.xml
Cool!
Where did you get the dvd.xml or what do you use to generate it ?
I got the script from another thread, "DVD Writing". I have bcc'd the
OP of the script and hopefully they can respond if they don't see the
thread.
