RE: 'Best' format for ripped DVDs?

Sam,

I have MTR 3.14 if you want it, I haven't had it fail yet:-)

I spent quite a while playing with this.  I decided I wanted to repackage

the VIDEO_TS folders partly because I find the whole VIDEO_TS thing a bit

untidy but mostly because I decided I wanted to keep my collection on a 1Tb

drive, with some room for expansion, with raw that wasn't an option, and

funding is low for a larger array :-)



My main priorities were no loss in quality of video or audio, keep multiple

audio/subtitle languages  (SWMBO is italian, and my son will hopefully be

bilingual).  I was actually keen on losing the dvd menu, as I find them all

rather annoying, and I've ditched all extras as well - I never watch them,

and I always have the original disk should I get an irresistible urge.



In the end I chose matroska (mkv) as the container, h264 as the video

compression, the audio is left in its original format mostly for simplicity

but also because any compression is negligble compared to video size.  Mkv

supports multiple languages nicely.



The process is this :  I use MacTheRipper to extract the VIDEO_TS folder

into a queue folder.  This takes about 30 minutes.  Then I have grabs a

VIDEO_TS from the queue, extracts the audio(mplayer), subtitles(mencoder),

transcodes(HandBrake) and repackages the result into an mkv file. This
takes

about 8 hours per disk on my mini.  And then it grabs the next VIDEO_TS

folder.  The script runs in the background and I can watch movies at the

same time



I'm not complete yet - about half way through my collection (300 disks is

going to take me 3 months!).  but every now and then the system mails me

that it is low on VIDEO_TS folders and I sit there and feed the disks into

MacTheRipper whilst watching telly, and fill the queue folder up.  This

means it doesn't require much intervention from me, so I don't really care

how long it takes.



The MTR stage is a bit fiddly, as I have to keep selecting "Main
Feature

extraction" and click go, ideally I would automate this more, I
believe it

would be possible with some applescript, but I've not had the time yet. Or

if anyone has any better ideas I would like to know.  Also some disks fail

completely in MTR, I believe MTR3 may solve this, but I've failed to find

the magic newsgroup where you donate money and



The resulting MKV is 2~4Gb depending on the movie so about 50% of the size,

I can see absolutely no degradation in quality on my 32" LCD, but I
did have

to do quite a lot of experimenting with the handbrake settings before I

achieved that (none of the fiddling increased the file size particularly,
it

just vastly increased the transcode time - and presumably CPU required to

playback).



As for playback, VLC plays nicely including grabbing he various subtitle
and

language files.  FrontRow plays just fine with Perian and Sapphire

installed, but doesn't easily allow subititle switching.  I will most
likely

use OSXBMC when it is more stable, or maybe I will try to contribute to the

Sapphire project, as that is really the interface I like best at the
moment.
