IDX/SUB Out Of Sync

[EvilRyu]

Hi, in some movies the extracted original subtitles from the DVD in idx/sub format are out of sync when i play them back with directvobsub or with the use of AVISynth and the "VobSub" command.

I tried several tools like VobSub Configure, VobSub Ripper and the Vobsubber option in MeGUI all with the same result with the exception of MeGUI which extracted a blank idx/sub file.

As i said it doesn't happen on all DVD movies. It happens for example in the movie "Vantage Point" and the idx/sub are out of sync ~1 min. late.

Hi,

Does it occur for NTSC DVDs or PAL DVDs or both?
Is the delay fixed (an offset) or progressing during the movie (more like a drift)?

It's for PAL only because i use Region 2 always. The delay it's fixed.

yes i know your problem. the exact subtitle delay is -68200ms

i have muxed to mkv and there you can type the delay at the subs. after muxing its all ok.

Thanks, but do you know why this is happening? Just out of curiosity.

And also isn't another way to change the timing in idx/sub? Because i want to hardsub them.

I think you can directly edit the idx with notepad and type the delay in here if i am correct, just i don't know the command.

Edit - Now i am really confused, it seems the timing is completely wrong, it's not fixed not drift either. In some parts of the movie the timing is correct, in some others subs appear too early or too late, it's really messed up.

Hi,

How to add a delay is explained in the idx files:

# To repair desyncronization, you can insert gaps this way:
# (it usually happens after vob id changes)
#
# delay: [sign]hh:mm:ss:ms
#
# Where:
# [sign]: +, - (optional)
# hh: hours (0 <= hh)
# mm/ss: minutes/seconds (0 <= mm/ss <= 59)
# ms: milliseconds (0 <= ms <= 999)

Thanks i found with a little searching how to do that but read my above post, the edited part in bold in particular.

Edit - Never mind, i solve it. I forgot to put the "-" in the delay command in the idx and that confuse me and i thought the subs timing was completely wrong, which wasn't. After i put the "-" and the correct delay of course the subs displaying perfectly from the start of the movie to the finish. Still, i am curious why some movies cause this and others don't need any timing correction, and i always use the same tools.
