Using DGMPGDec and Vapoursynth - automatically detect episode cuts for .d2v

[pat1432]

Hello, I'm using DGIndex to create .d2v files of DVDs of animated shows with 6 episodes per disk. I can manually identify the cut for each episode by scrolling through the DGIndex screen, but I'm wondering if I can automate this and eventually script it to encode all 6 episodes? MakeMKV seems to be able to identify each episode automatically but I was hoping to combine DGIndex with Vapoursynth. Thanks!

Not with DGIndex, no. You can separate out the episodes when decrypting.

When you say decrypt, do you mean with MakeMKV? The discs are already decrypted into VIDEO_TS folders, but I can use MakeMKV with them to create individual MKV files. I intended on using DGIndex as my understanding was that MakeMKV doesn't preserve everything VapourSynth needs. Thanks.

No, I mean with a real decrypter, one such as DVDDecrypter.

Thank you, I found the PGC option which creates correct .VOB files per episode. Do you happen to know of any software that will do the same with a VIDEO_TS folder directly? DVDDecrypter insists on a disc. Command line options would be a bonus.

Thanks for the help!

Check out PGC Demux. It's a tool for grabbing individual episodes or titles directly from a folder without needing the actual disc. It won't re-encode, but it gives clean, demuxed streams you can them feed into DGIdex or Vapoursynth workflows.

Thank you! I looked at that and might go that direction, but the lack of command line input is a bummer. I'm thinking my final workflow will be a python script to first convert all my video_ts folders back to individual ISOs, and then a second script to mount each one and rip the episodes with dvddecrypter. dvddecrypter is a little finicky with the command line but I think I'll get it working.

***EDIT*** so it seems like I was mistaken about PGCDemux and command line support, I'll look more closely at that as an option as well.

Thanks you all!

I was going to suggest creating an ISO followed by mounting it, but you already know that way. I know nothing about command line, though. I guess the PGC method suggested by Wenny will do what you want.
