Hi,
I have some Video Cassettes which I wish to add their soundtracks to the DVDs of the same movies.
(They're very old and rare and because of the mullahs ruling in my country they've never been digitized and you know Iran's dubbing art(In Persian and French: doubler) was the best in the whole world before the English-Islamic revolution and it died out when "the Ayatollahs(Arabic Word, means: The signs of GOD) ripped the soul out of our beautiful country"!)
I know it's not an easy job and it surely needs lots of time to spend on.
The VHS movies are PAL, so when I capture their soundtracks, the framerate of audio streams will be 25fps.
My DVDs are NTSC and the video streams have a framerate of 23.976 with 2:3 pulldown(which makes them 29.97) so the AC3 framerate should be 29.97 as well.
Therefore I will:
1. Demux all the assets of DVD,
2. Capture the audio stream and optimize the sound quality,
3. Encode it to AC3.
4. Change the audio framerate.
4. The problems begin!
Could you please help/guide me on these:
How do I synch the captured audio stream with video?
I know changing the framerate with BeSweet may not be enough because the length of captured audio is not the same as video's and it usually has a different time.
should I import the video and audio streams in an editor like Ulead MSP(if so it's the worst and most time consuming part) and edit the audio to make it have a good condition? Will the resultant audio be in synch when imported in Scenarist to do the re-authoring part? Is there any other way better than this?
5. Make a scenarist script with ReAuthorist.
6. Import the assets in scenarist.
7. Add the new audio stream and do some edits(Scenaris Project).
8. Create DVD-Video!
9. Update the ifos.
10. Burn the ISO image with DVDDec.
Done?! Any other step?
P.S.
Do you know how big film companies convert old magnetic movie soundtracks to the digital formats?
I thank you all in advance for whatever information and ideas you can provide. Any help and guidance is greatly appreciated.
