I just got done authoring The Stand onto two DVDs and I think it might be useful to commit what I did to the forum for future rippers.
First, its hard enough even finding anything on the forum about it because the word "Stand Alone" is so often used. But here's the only post I found on the matter and it delt with the audio sync
http://forum.doom9.org/showthread.php?s=&threadid=30181&highlight=audio+sync+stand
Now the Stand is difficult not only because is it a hybrid NTSC/FILM at 29.97FPS, but also because the audio on episodes 2+4 become out of sync after ripping. The NTSC/FILM mix is really weird. Its FILM everywhere except when it transitions between scenes, then its NTSC. Can anyone explain why that is?
I used DVDDecrypter, DVD2AVI, AVISynth, CCE 2.50, AC3 Delay Correcter, and DVD Maestro. I'm following doom's CCE guide except where i need to IVTC and correct the AC3 delay.
First, in DVDDecrypter, I rip in ifo mode PGCs 1+2 on both sides of the disc stripping the directors commentary and demuxing the M2V and 2ch AC3. Loaded the M2V into DVD2AVI and didn't forcefilm. Next, I used the following AVISynth script in CCE:
LoadPlugin("D:\mpeg2dec.dll")
LoadPlugin("d:\decomb.dll")
mpeg2source("D:\DVD\STAND\stand.d2v")
Telecide()
Decimate(mode=1,threshold=50)
resampleaudio(44100)
Load your M2V in bitrate viewer for the VIDEO settings and follow Doom's guide for the GOP and Quality settings.
I didn't check very much, i think just Add Seq. End Code, Lin Q. Scale, and DVD compliant -- but don't hold me to that cos I might also have done ZigZag.
...ENCODE... [I did a 2 pass] In advanced mode I set the avg bitrates to 3000 or 2900, giving the longer episodes the 2900 average.
If you are working with Episodes 1+3 your audio should be in sync and just import them into your authoring programs.
For Episodes 2+4 I (and the other guy in the SVCD forum) ran into bad audio sync problems. What I ended up doing after encoding the M2Vs is a long trial and error process of finding the appropriate delay in AC3 Delay Correcter.
Here's the link to the file: http://www.doom9.org/Soft21/Audio/ac3delay_all.zip
You just load your ripped AC3 and plug in the appropriate delay for each one. Here's the delays that worked for me:
Episode 2: -1300ms
Episode 4: -1500ms (-1300ms might work too, but i was in a hurry)
The resulting AC3 files should be in sync with your video. Fiddle with it if its not to your satisfaction.
I ended up putting two episodes to a disc. Quality is to be expected from a 4:3 made for TV 2CH audio DVD job... Basically, if you think it looks bad, then it was bad to begin with on the original DVD.
BTW, make sure to setup your playlists correctly in Maestro (or whatever) so that you don't spend hours making the movie only to cause a coaster due to some sloppy IFO work. (I speak from experience).
