Media Backup

By Tom Ratcliff

Backup Media From DVD to Filesystem

  1. Get sector size and count of the DVD
sudo isosize -x /dev/sr0
  1. Write the contents of the DVD to an ISO
sudo dd if=/dev/sr0 of=dvd.iso bs=2048 count=2131422 status=progress

  1. Mount the ISO and inspect the contents
sudo mount -o loop dvd.iso /mnt/iso
ls /mnt/iso/VIDEO_TS/

  1. Use FFmpeg to convert VOB to preferred format

For lossless

ffmpeg -i VTS_01_1.VOB -c:a copy -c:v libx265 -preset ultrafast -x265-params lossless=1 ~/mycoolvid.mkv

For compressed choose a suitable crf (higher the more compressed, lower closer to lossless)

ffmpeg -i VTS_01_1.VOB -c:a copy -c:v libx265 -preset ultrafast -crf 21 ~/mycoolvid.mkv

If there’s multiple .VOBs, you can concat them with a shell script and then use ffmpeg (ie: shows to movie)

ls -1 *VOB | tr '\n' '|'
ffmpeg -i concat:"VTS_01_1.VOB|VTS_02_1.VOB|VTS_03_1.VOB|VTS_04_1.VOB|VTS_05_1.VOB|VTS_06_1.VOB|VTS_07_1.VOB|VTS_08_1.VOB|VTS_09_1.VOB|VTS_10_1.VOB|VTS_11_1.VOB|VTS_12_1.VOB|VTS_13_1.VOB|VTS_14_1.VOB|VTS_15_1.VOB|VTS_16_1.VOB|VTS_17_1.VOB" -c:a copy -c:v libx265 -preset ultrafast -crf 21 ~/mycoolvid.mkv

Script to bulk process

⚠️ this will remove the original content (copy of mkv)

#!/bin/bash
IFS=$'\n'
for i in $(find . -iname '*mkv'); do
  ffmpeg -i $i -target ntsc-dvd movie.mp4
  dvdauthor --title --video=ntsc -o dvd -f movie.mp4
  dvdauthor -o dvd -T
  mkisofs -dvd-video -o "${i%.mkv}.iso" dvd/
  rm -r dvd
  rm $i
  rm movie.mp4
done
