Subtitles missing when played on DVD Player

[bmwr51]

The problem that i have is that when i insert one subtitles file to a dvd movie and play it on my computer all seems ok with all the subtitles displayed as they should do.

But when i burn it to a dvd disc and try to watch it on my DVD player i found that some subtitles missing. I read somewhere that the problem probable is that the time interval between two subtitles should not be less than 300ms (if someone knows something else please tell me).

I wanted to ask if there is a program that automatically can check the time between subtitles and change it to an amount that you want.

Thank you in advance for your help.

If you're working with text subtitle files, like SRT, use Subtitle Workshop.

Tools/Information and errors will show any subtitles that overlap in time.

You can manually correct the times or let it do it automatically, though I'd want to check the result carefully.

Sometimes all you need to do is reduce the time of all subs by 1 ms.
Edit/Timings/Time Expander-Reducer

Or it has tools for estimating the correct duration.

AlanHK Thank you for your answer, but my problem is not overlapping Subs, but i think is that the time needed between two subtitles should be more than 300ms.

Do you know if there is a setting in the Subtitle Workshop to show as an error any subtitles that have between them less than say 300ms gap between them.

I know that in Subtitle Workshop the default space between subtitles is 1ms. Do you know a way to increase this time limit?

You don't have to have a 300ms or greater time between subs. I regularly make mine with a 2ms gap when the talking is fast. If you're losing subs it's for another reason. I don't use Subtitle Workshop so I don't know if the problem is with it or something else.

What process/software are you using to "insert one subtitles file to a dvd movie"?

How are you authoring the DVD?

Does your standalone DVD player have settings for subtitle? (Have you toggled it on)?

[bmwr51]

The programes that i use are

PGCDemux for demuxing
Muxman for putting everything together

I also use Subtitle Workshop to convert subtitles to .sup

My dvd player can play DVDs with Subs without a problem (DVDs from a DVD store)

Do you see your moves on your computer or on a stand alone Dvd player?

I watch in my standalone and all my subs show up. But I don't use Subtitle Workshop so I don't know if it's causing the problem or something else is.

I take it you use Subtitle Workshop to convert SRT to SUP, or are you using something else to do that part for Muxman? I usually create SSA subs and then use MaestroSBT to create subs in SST format which Muxman also accepts. I'm not saying SW is responsible, although it's beginning to sound like it since the rest of your workflow is solid. And I'm not claiming my way is necessarily any better, but it does produce nice-looking subs for DVD.

Do you have SubtitleCreator installed? Can you check the SUP file in there? Hit Tools->Manipulate SUP and VobSub (at the top), and then Open Sub (open the SUP file). See if you can read the dialog and the timestamps and that everything looks OK. I think that's what it says, but I'm not at the other computer at the moment to confirm. Being able to read the SUP file should be able to tell you if it was created OK.

Ok thanks I have SubtitleCreator installed and later today I will follow your suggestions. (at the moment i can't, i am at work)

Do you think that all this could be the fault of my standalone Dvd player and that somehow it has not have the ability to read Subs with short time limit between them?

Hi-

Do you think that all this could be the fault of my standalone Dvd player and that somehow it has not have the ability to read Subs with short time limit between them?

I really don't know. My instinct is to say "no", it's not the player's fault, but since I don't know what I'm talking about, I won't say that. My suggestions are to, 1) check out the SUP file and see if any of the subs are missing in that, and if they're all there, 2), try out the DVD in other players at friends or relatives houses and see if the players could somehow be involved.

In addition to using SubtitleCreater to view the SUP file, you can also read SUP files using SupViewer. And you can check the subs in the authored DVD to see if any are missing using DVDSubEdit.

If I had to guess, I'd say the missing lines are already missing from the SUP file you created, but it's just a guess.

I am 100% sure that the problem is with my dvd player (lg dv8800)

I first played the movie in my standalone dvd player up to a point that a subtitle is missing, looking it over and over again to make sure that indeed does not appeared and after that i took the same move to my computer, i watch it and i show the subtitle that missed without any lack or problem.

Its probable time to change my standalone dvd player with a newer one.

Anyway thank you for the help.

Anyone knows a program with such a function?

Not sure what you mean by that... If you mean the subtitle duration, DVDSubEdit can do that...
About your problem: It's actually quite unlikely that a player would have a bug in the code that shows the subs. It's well known that soft players are usually less stringent about standard, so it's not uncommon to see subs play in a soft player, but not on a standalone. That does not mean your standalone is bad. It usually means your subs are bad, but the soft players are able to ignore the problem.
Usually, it's quite hard to figure out what exactly is wrong with a sub that does not show...

P.S. This being said, there are players that are very touchy when it comes to subs. I remember r0lZ having problems with one of his player, even for subs that appeared to be quite legit...
