I wrote this scripts to help me rip educational DVDs into the cleanest possible format. I dunno if others will find them handy, but I see these as notes to Future Ron. If you find this useful, enjoy!
Note that at least some of the folder names I use are important for steps to work!
This script assumes you have the rough set of tools that I do:
ffmpeglsdvdmediainfofr.handbrake.ghbinstalled inflatpak
It's worthwhile ripping an ISO to a file, since I often find myself experimenting, and my DVD reader is slow (probably they all are :) ).
To find your DVD device, use blkid:
$ blkid | grep 'udf'
/dev/sr0: UUID="32b76f7000000000" LABEL="VERNON_REVELATIONS_1_2" BLOCK_SIZE="2048" TYPE="udf"
I suggest working from the working/ directory, which should be in
.gitignore To rip a DVD, I like to put them all into a folder called
working/originals/:
mkdir -p working/originals/
sudo dd if=/dev/sr0 of="working/originals/VERNON_REVELATIONS_1_2.iso"
That'll take awhile (~10 minutes for my drive). :)
I use lsdvd to get titles:
$ lsdvd originals/Dai\ Vernon\ Revalations\ -\ Volumes\ 1+2.iso
libdvdread: Encrypted DVD support unavailable.
libdvdread: Zero check failed in src/ifo_read.c:567 for vmgi_mat->zero_3 : 0x00000000010000000000000000000000000000
Disc Title: VERNON_REVELATIONS_1_2
Title: 01, Length: 01:52:34.500 Chapters: 36, Cells: 36, Audio streams: 01, Subpictures: 01
Title: 02, Length: 00:03:06.567 Chapters: 05, Cells: 05, Audio streams: 01, Subpictures: 01

It seems to vary whether they use chapters or titles. Decide what you want to rip!
Still working in working/, run ../roncoder.sh and start figuring out
settings! All settings are passed via environmental variables and have fairly
good defaults (I hope!):
Source:
* DVD = /dev/sr0
* Mount dir (MOUNT) = /mnt/dvd
* Directory to rip from (RIP_DIR) = /mnt/dvd/VIDEO_TS
* Detected that you're using a real DVD device! If it should be loopback, use LOOP='-o loop'
(Will attempt to create the mount dir, if needed, then mount the disc)
Press <enter> to confirm...
You will likely want to set DVD to your disk:
Source:
* DVD = originals/VERNON_REVELATIONS_1_2.iso
* Mount dir (MOUNT) = /mnt/dvd
* Directory to rip from (RIP_DIR) = /mnt/dvd/VIDEO_TS
* Detected that you're using a loopback file! If it should be a device, use LOOP=''
(Will attempt to create the mount dir, if needed, then mount the disc)
Press <enter> to confirm...
The rest of the settings should be fine, so hit enter:
Video settings (RIP_VIDEO=true / RIP_VIDEO=false to toggle):
* Rip the DVD = ENABLED
* Result file (RESULT_FILE) = ./output.txt
* Presets file (PRESETS_FILE) = /home/ron/projects/magic/roncoding/presets.json
* Video output directory: /home/ron/projects/magic/roncoding/working/videos
* Quality (QUALITY) = 19
* Crop (CROP_TOP:CROP_BOTTOM:CROP_LEFT:CROP_RIGHT) = 0:0:0:0
* Split chapters (SPLIT_CHAPTERS) = true
* Titles (TITLES) = 01 02 03
Preview settings (toggle with PREVIEW=true / PREVIEW=false)
* Preview = ENABLED
* Preview frames (PREVIEW_START + PREVIEW_END) = 0 - 2000
Thumbnail settings (toggle with RIP_THUMBNAIL=true / RIP_THUMBNAIL=false)
* Rip the thumbnail = ENABLED
* Output dir (THUMBNAIL_DIR) = /home/ron/projects/magic/roncoding/working/thumbnails
* Offset in seconds (THUMBNAIL_OFFSET) = 3
(Press <enter> if that looks right)
By default, you'll get:
- A preview (first 2000 frames) of the video in the
./videosdirectory - All titles
- All chapters
- A thumbnail (@ 3seconds) in the
./thumbnailsdirectory - No cropping
- Quality 19 (a decent default)
- My presets file, which I copied from a site I respect
- Output information to
./output.txt
If you want chapters to be split, you won't be able to preview - you'll just
have to set PREVIEW=FALSE SPLIT_CHAPTERS=true and wait longer. Limitation of
the tools, unfortunately!
Make sure the title/chapters are correct, then go ahead and hit enter! You can change basically everything with the environmental variables listed in the information block.
It'll print a lot of information, and will hopefully eventually finish.
Once you have the previews, open up one or more, and determine:
- Which titles + chapters you actually want to rip
- Check the edges for black or blurry and set the
CROP_*variables accordingly - Check the
output.txtfile - you want bitrates between roughly 1500 and 2500 - Make sure the thumbnails are correct. You may have to do a custom thumbnail for each video, or even generate them by hand - nothing we can do there, unfortunately
There's no easy way to change single files in the rip, so you want things to be
correct on-average. If there are substantially different settings required,
you'll have to run this twice settings TITLES accordingly.
Once you get it all the way you want it, set PREVIEW=false and let 'er rip!
Be sure to check output.txt again, as the whole files might be different.
You'll need to make sure that the titles/chapters are in the order you want, as well, which is kind of a pain.
You'll have to do titles the hard way, unfortunately. Create a folder called
titles/ and files named in the same way as videos/ and thumbnails/,
except with .txt extensions. Put the titles in those files.
It'll look something like this:
$ ls *
thumbnails:
10.jpg 12.jpg 14.jpg 16.jpg 18.jpg 1.jpg 21.jpg 2.jpg 4.jpg 6.jpg 8.jpg
11.jpg 13.jpg 15.jpg 17.jpg 19.jpg 20.jpg 22.jpg 3.jpg 5.jpg 7.jpg 9.jpg
titles:
10.txt 12.txt 14.txt 16.txt 18.txt 1.txt 21.txt 2.txt 4.txt 6.txt 8.txt
11.txt 13.txt 15.txt 17.txt 19.txt 20.txt 22.txt 3.txt 5.txt 7.txt 9.txt
videos:
10.mp4 12.mp4 14.mp4 16.mp4 18.mp4 1.mp4 21.mp4 2.mp4 4.mp4 6.mp4 8.mp4
11.mp4 13.mp4 15.mp4 17.mp4 19.mp4 20.mp4 22.mp4 3.mp4 5.mp4 7.mp4 9.mp4
Copy the metadata.nfo file from this project into the base folder. Fill out
everything except for NN and Title, those are filled in automatically based
on the titles/ directory.
Once that's all done, just run ../finalize.sh. That should put everything
together!
Random thoughts:
- Ripping thumbnails without videos is fine, provided the video files are already ripped
