View Full Version : Maestro and NTSC movie: subtitles out of sync !?

I read bunch of posts about this problem and nothing helps in my case...

I have NTSC M2V and AC3 source with subs that I rip with SubRip.
Resulting subs file have wrong timestamps - no matter what I do, they starts correctly and progressively goes out of sync and at the end of the movie, they are 9 sec. "in the future" !
Timestreching of subs for 9 secs ("minus") looks like a solution but subs are still out of sync occasionally - they are good at the beginning and at the end - but in the middle, there are again out of sync ...

It is obvious that Subrip didn't do job well - so Maestro can't make propper sync either.

What to do to rip subtitles correctly? I tried all ASCII formats incl. picture formats but timestamps are constantly wrong :(((


Please, anybody have solution ? I am going slightly mad ... 8-(

It was discussed before. I have same problem and it's problem that DVDMaestro have. I couldn't find any other solution than just use SubRip to make necessary corrections and than import in Maestro.

I used Pulldown 0.99d to remove drop frame flags which helped a bit and time stretching in SubRip to fix more and I have acceptable result ... But it is spartan solution :(

Can't believe that there is no some simple way to work around this ?

Don't use pulldown 'couse DVD have to be at 29.976(30.000)FPS for NTSC. There is option in SubRip when converting to .stl subtitle to use pulldown but didn't help. I'm to still looking for right solution.

I didn't make pulldown - I only removed drop frame flags according to tips in pulldown manual. So, video stream is still 29.97

OK. Sorry. My bad.
If you find solution please report here. I'll look in to that too.

Removing drop frame flags is solution but not a complete one. Someone posted it here, at subtitles forum, but it doesn't work in my case. I still need to do stretching and little manual position changes to have subs forced in sync (they are stil not perfectly synched but almost - I think it can't be better than that with this method inspite all efforts I made :( )...

It is obvious that subititle rippers can't deal with NTSC source. I tried to rip subs with Subrip and VobSub but problem was the same ...
Resulting subtitle file already has wrong timestamps (beggining was fine but then progressively goes out of sync - at end for more than 9 sec.)

Would be nice if anybody can explain why there is problem to extract correct timestamps? I assume because of inserted frames that are present in NTSC (to achieve 30fps) ... but there must be some way to include/exclude/whatever that in calculation during ripping ?

How you guys from NTSC countries solve this problem ?

We from PAL countries (like FFROMS and me :) ) has no such problems ... unless we must deal with NTSC source ... :(
