Extract multiple PGCs

[kurbads]

I have DVD9 wich has one title set. The title set consists from 66 PGCs. The sound is PCM. I would like to batch extract 20 of PGCs, compress sound and recompress video to fit on DVD5. Then reauthor each PGC with IfoEdit and replace in original DVD with VOBEdit. Which program would you recommend?

Something like https://forum.videohelp.com/viewtopic.php?t=234240 , you can also demux with pgxdemux. And you can shrink mpv/mpg files with rejig. Or shrink the video after with dvd shrink, dvd rebuilder.

Hi-

I don't know about batch extract, but you can extract using PGCDemux, reencode the audio and video, remux (Muxman is better than IFOEdit), and then use VobBlanker to replace the PGCs you reencoded and blank the rest.

With PGCDemux you have to extract each PGC manualy. Secondly it does not auto numerate extracted PGCs and overwrites extracted material if not directed to new folder. Which is quite messy. If DGIndex had an option "split on new PGC"...

If you can find a batch extractor, then good for you. While it's certainly possible to overwrite previously extracted PGCs when using PGCDemux, it won't just automatically do it. It will warn you first. I extract up to 20 PGCs at a time every so often. If you're organized, it's no problem. Muxman's the one you have to watch out for. It'll happily overwrite a previously authored DVD, without saying it's about to do it.

Each file will have to be opened in DGIndex anyway. Is not there a way to find out starting and ending frame number of each PGC, to just write values in aviscript? The same numbers could be used to convert correspondig audio. Ah, but this leaves subpictures unextracted. Probably will have to go the hard way... I will name the folders with numbers of their PGCs!
