How do you load DVD video to synch?

[Like the Cure]

Okay, heres the sitch: Ive got a DVD with horrible English subs (Battle Royale), and I'm trying to replace them with a correct translation I found. I'm then going to reauthor the DVD so it'll be the same as when I started, jsut with correct subs.

Here's where the problem begins. I followed this guide (http://forum.doom9.org/showthread.php?s=&threadid=83566) using my found subs, and upon mounting and watching my new dvd image, i find that the subs are totally out of synch. This is not suprising, so I began searching for ways to synch the subs.

Nowhere at Doom9 did I find anything on how to load the dvd video in the subtitle programs to synch the subs. Subtitle Workshop and any other program I tried wouldn't load the m2v file that DVD Decrypter produced (or the subsequent renamings, ie mpeg, mpg, mpv, etc). I converted that to avi to find that it added 30 minutes to the length--poor encode, i guess. I even used DVD Decrypter to make 1 VOB file for the movie, and in loading that into Subtitle Workshop and adding subs (the bad subs ripped directly from the dvd, so they should synch up) and they didnt synch up, they were off. Yeah, I could change it to synch up, but then it would synch up to the VOB file in Sub Workshop, and whos to say if itll synch after authoring the dvd (because the VOB file was about a minute longer than what PowerDVD said the length of the DVD was).

I also tried encoding to AVI using DGDecode (indexing, writing an avisynth script, and converting with virtualdub) and the AVI was also about a minute longer than PowerDVD's clock.


I understand that my problem above isnt very organized, but I thought I should get it all out on the table. If anyone can help me at all, I'd be much appreciative. I did search through every page of the Doom9 Subtitle forums for an answer to my problem, but unless its subject header was misleading, I dont think theres and answer out there. Im afraid I might be missing something thats like common knowledge, so If anyone has any input, that'd be great. Thanks!

Okay, I'm not totally sure this is gonna work, but heres hoping: I made a very low quality AVI from the single VOB I made with DVD Decrypter, and since it matched the length of that VOB exactly, and didnt have any skips or stutters, I thought I'd synch my SRT subs to it in Subtitle Workshop. Well, its strange, because the subs were spot on at the beginning, and the subs were spot on at the end, but the subs were not spot on, however, in the middle. Thats actually a bit of a generalization, as it seemed like random lines were off (only by a bit, mind you, but enough to bug the hell out of me).

So right now, I'm about halfway through manually synching the subs, line by line, and I guess theres one question thats really bothering me: Should I be concerned about the length differences between the VOB file and what PowerDVD says the movie length is? Is there some rational explanation, like that PowerDVD isnt very accurate, or somehting like that?

In fact you didn't need to encode. There is a SW called Vfapi that can frameserve from avisynth script. Just load your script in Vfapi and "Convert" to avi. This will save a fake avi file that you can load in Subtitle Workshop.

As for subs, this happens often. Probably you found subtitles ripped from a different release of the movie, from differnt contry or director's cut or similar.

this is my way for getting subs into sync
- extract ac3 from vobs
- convert ac3 to mp2
- load mp2 in subtitlecreator or any other sunc program
- and look for matching srt
