Extract – DVDDecryptor.
It extracts by film/chapter/cell
Then
Video
1. You need Canopus ProCoder and convert your PAL to NTSC 23.98 (set option “get first nearest frame”)
You must encode new MPEG2 file WITHOUT change number of frames, ONLY chabge speed of playing
2. You need pulldown.exe – utility to convert 23.976 progressive source to 29.97 interlaced
OR
You can encode with procoder by setting “23.976->29.97 pulldown”
Note. You can change speed of video by using VirtualDubMod. VDM can save AVI files from MPEG2 sources, and change it’s speed without change number of frames
Audio
1. you need to decode audio to wave files and change speed to 25/23.976 – Samplitude Studio, Sound Forge, Wave Lab, Nuendo and many other
2. encode to AC3 by Sonic Foundry Soft Encode, Scenarist AC3 Encoder, Surrcore AC3 encoder etc.
If your PAL video interlaced, then you must transcode your video by
a) Software – Canous Procoder (slow and low quality result)
b) Hardware – you can find many transcoders with Google 🙂
if you have subtitles you must extract it by SubRip, then (like a sound) change speed.
After all you can author a new DVD-ViDEO disk 🙂
