DVD Compression

[doria]

How do I go about compressing DVDs so that I can fit them on a disc? Every time I try to burn a DVD I get a message that says I need approx. 7G of free space and the only discs I can buy are 4.7G.

Not only am I new to Linux but I am also new to burning DVDs so I am a double newb.

I don't know if it matters but I am running Mandrake 10 kernel version 2.6 with KDE and attempting to use K3B for burning DVDs

you have to copy the data off the dvd, and make a new iso

look for tutorials on dvd+rw tools, and mkisofs

1) Rip the DVD title(s) to hard drive useing vobcopy:

vobcopy -l -t movie

2) You now have 1 VOB file. We need to demutliplex it and get the M2V and AC3 files out of there.

tcextract -i movie.vob -t vob -x mpeg2 > movie.m2v
and after that:
tcextract -i movie.vob -a 0 -x ac3 -t vob > movie.ac3

This will produce a movie.M2V and a movie.AC3 file.

3) To requantize (shrink ) your movie so it will fit on a single DVD-R (4.7) do as such:

tcrequant -i movie.m2v -o movie1.m2v -f 1.5

This will produce a file called "movie1.m2v"

4) Now we need to re multiplex those 2 files into a compliant DVDauthor file:

mplex -f 8 -o movie.mpg movie1.m2v movie.ac3

This will produce a file named: "movie.mpg".

5) Now create a dvd structure in a folder named newdvd

dvddirgen -o newdvd

6) Populate the filesystem like so:

dvdauthor -o newdvd movie.mpg

7) Create DVD information (IFO) files:

dvdauthor -o newdvd -T

8 ) Burn the Video_TS and Audio_TS created with K3B DVD Video mode.

9) Now what you need to do is find the options for your DVD player (read your manual) and set your tv as a 4:3 letterbox so the player will add black bars on the top and bottom of your screen when you play the movie.

Programs used.
1. vobcopy
2. mjpegtools
3. transcode
4. dvdauthor
5. k3b
And all deps.

In one of my pc magazines, there is an article showing you how to rip and compress a dvd movie to fit on a standard 4.5 gb dvd. I seem to remember that they used a single program to do the whole process. I can't go into detail, because I need to get the magazine, the problem is that it is somewhere in the murky depths of my room. When I find it, I'll post about it.

I have seen a few such programs but they always seem to end in errors this method can be applyed to any form of script just add a eject /dev/dvd here and there and all is good.
Dvd Menu's are very possable im still looking at a way to do them from console.
Subtitles are a bit more diffacult.
The point is if it can be done in windows linux can do it better.

This is just a quick hack.
