Rip and splice DVD

[Patrick Neame]

Dear all,

I want to rip a few DVDs to my hard drive using RipIt and then edit them together. Does anyone know if this is possible?

The films in question are Schlindler's List on two DVDs and the Back to the Future trilogy which obviously comes on three!

Thanks

Patrick

Hi Patrick

Toast has a facility for burning multiple VIDEP_TS folders onto the same disk. Or you could RIP the disks, use MPEGStreamclip to convert to DV, edit the DV files(iPhoto will do) and then burn. If you are trying to squeeze 3 DVD's onto a single one, you will have to compress the DV stream quite heavily and the quality is going to suffer. You really need to use Compressor(Final Cut Pro) to do a good job on that. But if you want it for an iPad/iPhone I'd suggest editing the full DVD streams together and then using Handbrake to compress it for you.

You are going to need lots of disk space - 1 hour of DV is 13GB from memory

Hope this helps

Rick

Hi Patrick
Firstly, I won't address the legal issues here as I'm not a lawyer but
I would assume that these are only for your own personal use and that
you own the DVDs in question.

The issue you have is that you'll likely run out of space on a DVD to
fit all these films you want. You can probably burn a data DVD without
issues if you ripped the films into an MP4 video format. Each film
would be about 1.5Gb at a good quality.
I've not used RipIt before but does it seems to do two things.
1. Makes a full copy of the dvd's contents, I.e, copies the VOB files
In the video_ts folder
2. Converts those into single files that iTunes/QuickTime likes.

Part 1 won't help you as the end result will be the same size as it is
on the DVD, 7.8Gb or there about. So trying to combine 2 or 3 of those
into a single DVD is impossible.
Your only chance would be to do part 2 and then use something like
Roxio Toast to try and burn a new Video DVD. However when those DVDs
are burned, the video files are decompressed and it's likely that it
would still want one DVD per film. Hard to tell without trying.

That probably doesn't help but maybe explains a few things.

I don't think this is at all legal unless you are making extracts for 'fair use, parody or educational analysis' etc. I suspect you may know better than me since you work in a theatre :^)

It is entirely possible to do though, your choices depend on if you have DVD Studio Pro installed (& the Quicktime MPEG2 codec).

A.

Use an older copy of MacTheRipper (version 2.6.6 or earlier) because it supports export to VideoTS (without the copy protection). Then use MPEGStreamClip to convert the VOB's to DVPAL or your desired editing format. MPEGSteamClip requires the MPEG2 plugin to demux the video.

B. 

Use a recent copy of Handbrake to rip to H264 or something that iMovie/ your editor likes. Just be sure the quality is OK since there are a bewildering array of presets and aspect ratios.

I suspect A is slower since you rip & then convert but you can have more control over the initial format. You will need to convert back to MPEG2 when it is time to burn to DVD if that is what you are planning to do. DVDSP or iDVD will do it for you. I don't think you can skip all the transcoding - editing raw MPEG2 steams is a royal pain (FCP chokes & DVDSP won't let you cut between i-frames). Maybe FCP X can save you here?

Both methods should be cost free (aside from DVDSP & your editor).

If you are trying to make a single DVD apps like Toast or DVD2OneX will re-compress an unprotected VideoTS to try to cram them onto one disk, but you have less control over the joins.

You may find you need to use a Dual Layer DVD (~8GB) to keep the quality for long films, but DVD players can be finicky about playing burned DL disks.

Personally I think you would be better off not cramming 6 hours of Marty McFly onto one disk otherwise it may look like minecraft in a blizzard.

Re-reading the original message and the replies(including mne) makes it clear that none of us are too clear about what you want to do with the video after you've RIPped it. That's the easy bit - whichever tool you use(Ripit or MTR) will give you 3 VIDEO_TS folders containing MPGEG2 video. You should be able to get rid of all the DVD overhead whichever tool you use(so just RIP the main movie).

What do you want to do with these 3 folders when you've got them?

Compress )a lot) to burn them back onto a DVD?

Something else(iPAD/iPhone, AppleTV...)

Good point Rick,
Patrick, if you are planning to use them on a computer just the ripping is enough, DVDPlayer on the Mac will open VideoTS folders (in the File menu).
It is usually safest to export to a DVD disk image instead of burning a DVD, so you can check the quality in DVDPlayer then burn that from Disk Utility (iDVD used to bork many disks unless you went via disk image).

Sorry evrybody I should have ben clearer. Schindler's List provides a good example; it's so long that it goes onto two DVDs. When you rip it (with RipIt) you get two files on your hard drive which play through DVD player (File>Open) quite happily. What I'd like to do is play the film without closing down the first file and opening the second, i.e. splice the two together.

Similarly with Back to the Future I'd like to splice all three together and remove the repeat sequences at the start of BttF 2 as well as the credits (I could do the same for the BBC's Pride and Prejudice) so that I have BttF as one seamless film.

The copyright point is probably somewhat murky in the BttF example not so, I submit, in the former.

Amended version, please ignore the previous one.

Clearer now!

You classy way is to use MPEG Streamclip to do this, but you may need the QuickTime MPEG2 plugin to use this. Inside the VIDEO_TS folders you'll see a load of VOB files that hold the MPEG2 video content of the DVD. Depending on how you ripped them, there may be more than one, but the big files are the movie. The others are the 'extras' and other rubbish that they stick on the DVDs. 

What you need to do is convert the DVD video files to DVPAL, which will give you the highest quality to start with. You can then edit these(iMovie is more than adequate) as you wish(you're just going to be trimming the movies,so little expertise is required). You then need to compress the result to save some space. DVPAL files are big!  I'd use Handbrake to do this and use the AppleTV preset which should give good quality

If you have the QuickTime component then just download MPEG Streamclip:

http://www.squared5.com/

Use the 'Make DV' option

If you can't do this, it's a bit more fiddly. Possibles:

I think you can use Handbrake to RIP the original DVDs as it will use the VLC copy protection busting library.  You may even be able to rip your VIDEO_TS folders directly(try it). I'd tell it to use the AppleTV preset. You can then edit the M4v files in iMovie.

If you have QuickTime Pro you can trim the clips using that. 

Remember when you've finished to trash all of the intermediate files to free up space. Depending on how fast your Mac is, it will take some multiplier of the run length of the movies to extract, edit, export and recompress the videos

Hope this helps. If you want more info contact me off list. I'm sure others will have input too as I've probably missed something out from this quick post

Good luck
