Subs Way Out Of Sync... Need Help

[Master Yoda]

Just backed up fun with dick and jane (R2) Its a arccos disc, so first i ran ripit4me along with FixVTS. With this new files i created a iso then demux as normal. I used demux by vobid like have have done before on a arccos disc. In scenaid i then unticked the first vobid again like i done on a arccos in the past. Compiled.... ran batchifoupdate and then tested plays fine audio in sync but the subs are way off. The speech will come then about 1 minute later the subs for that speech then come up.... any ideas ???

[D3s7]

does fixvts and the like update the sub timestamps?

I could see that being a problem depending on how the arccos disk is layed out....

[Master Yoda]

Im dont know if it does update the timestamps to be honest. The ripped files that was created using dvd decrypter in conjuction with ripit4me and using fixvts after work fine, subs in sync it's only after demuxing, re-encoding, re-compiling ... etc that the subs go out of sync.

[D3s7]

hmmm.. interesting...

how big is the .sub packet? Might be worth looking at to see where the problem is

[Master Yoda]

if you mean the .sub file then it is 16.3MB although i have 2 VTS_03_VSUB_V002.sub and VTS_03_VSUB_P1A1.sub. Now like the last time i did a vobid demux(think it was avp) in the subs folder i had two sets of subs the same. Names like above, where i had to delete the P1A1 etc.... subs and keep the ones that ended V001,V002 and V003. So i have done the same here by deleteing the, well moving somewhere else on the drive the P!A! subs. But i thought only the srt files and the bmp's was used did'nt think the .sub files which are just in the VTS03 folder and not the subs folder was used.

i have been more partial to psl2 plugin wizard in pgcedit but i use vobblanker ( i had problems the first time i tried fixvts ) .. then reiso and i just do regular pgc demux

[Master Yoda]

I see, to be honest i wanted to really try and fix this without starting from scratch so i dont have to re-encode again. If i cant get it sort then i will try again but instead of a vobid demux i'll do a pgc demux. It just seems strange that the audio stays in sync but the subs dont

If is only one suggestion and could apply for your problem.

I would use that psl2 plugin, because it makes available more helpful tools. If the Wizard was successful, call under Tools -> Display PGC starting time (SCR) for your problematic PGC. There is the chance that a delay exists. If a delay exists, you can use DVDSubEdit and 'Re-time selected subpics'.

If they are out by a fixed amount throughout, then my method posted in this thread will work without having to rip anything again

I have found that the Davinci Code R2 suffers the same issue as was mentioned at the start of this thread. Any ideas would be very welcome!

[Trahald]

i just started using ripit4me/fixvts instead of psl2plugin/vobedit i'll see how Clicks subs come out.

Hi!I have found that the Davinci Code R2 suffers the same issueFrom everything I've read, "The Da Vinci Code" has not yet been released anywhere in the world.

Where can I purchase a copy today?

[BruceyMc]

It came out last Monday here in the UK!

[bonehead66]

I'll second that I bought it today, and to my disgust the latest AnyDVD 6.0.8.0 will not remove the copy protection I had to resort to RipIt4Me.

[setarip_old]

@BruceyMCIt came out last Monday here in the UK!Thanks for the info ;>}

Since it's a Columbia/Sony Entertainment release of an Imagine Entertainment release, using "RipIt4Me" (including the "FiXVTS" stage) should give you a good rip...

[BruceyMc]

I have managed to get a successful rip which plays fine using ifoedit and other software players but when it comes to re-encoding the audio is fine but the subtitles are over a minute late in appearing. I have done a few arccos titles before but never had problems like this little swine!

[jeanl]

In Ripit4me, if you re-encode, you want to select the option "movie-only" because that's the only option that does remove all the tiny cells at the start of the movie, which are responsible for the mis-synchronization between audio/video and subtitles.

@jeanlIn Ripit4me, if you re-encode, you want to select the option "movie-only" because that's the only option that does remove all the tiny cells at the start of the movieAre you saying this is only a problem when re-encoding, but not when transcoding?

I ask because I've never encountered this problem when making Full DVD backups, whether using DVD Shrink, DVD95Copy, or DVD2One...

Also, doesn't the "Remove tiny cells" checkbox in "the "RipIt4Me" structure (Step 3B) take care of this?

[Trahald]

i can see the issue.. basically as d3s7 stated earlier. the sst is based of the scr values in the sub packets which are way off cause of the accros. with click the audio delay is 80000 (about a 1:20) which is corrected , but the subtitles are not adjusted so they are 1:20 late. im gonna try to make a program that will fix the sub (sst) times by a certain given delay. the delay can be taken from the ac3 file name as it will be the same. then scenaid can be run from there.

gimmie a day or 2.. as far as fixing vsrip to permanantly handle it we'll see. d3s7 is more familiar with it. i have the source for vsrip/vsconv but im i havent dived into it and dont wanna break anything in it. . but there is enough stuff in the temp vob file that the closed captions and subs get demuxed from to automatically adjust for the delay.

the delay caused by the arccos is the issue. (vsrip never expected 0 duration cells at the beginning of hte movie. even if the cells are removed, the SCR still keeps ticking. vsrip uses the SCR (or the PTS - i havent checked) and doesnt figure in delay since delay is normally so minimal). Since the subs are copied whole with dvdshrink it would not effect it

[Trahald]

and i apologize to mpucoder for calling it 'delay'. just lack of a better term. ;)

Only a problem with re-encoding, not in Shrink or Recode. I know it's a major problem for audio/video sync, I'm not sure about subpics, and the problem arises from a limitation in DGIndex which does not expect useless tiny cells at the start of the movie, which can have a bit of video and no audio at all (that throws the re-encoding off).
As far as I know, Remove tiny cells removes all the tiny cells in movie only, but not all of them in other modes (it's discussed in the history IIRC). That's why movie only is the recommended mode for re-encoding...

Ok.. on the batchccews page https://sourceforge.net/projects/batchccews/ on sourceforge i put up subtitle delay fixer. it will accept scenarist style .sst files and update them with the delay give. it overwrites the file but creates a .backup file if you need to go back. to figure out the delay you need, use the delay from the audio file (its listed in brackets) for guidance. generally its gonna be a huge number like 40000 - 80000 or more depending on how many crap cells there were in the beginning of the movie vts.

here is a audio file name after processing with dif4u 'VTS__01_P01-80-448K-[80166]ms(fixed)-ch6English.AC3' use the 80166 for the Delay for the subs.

[Zeul]

Works on my test sst :)
Perhaps adding an additional label stating when to use [-] and when not to. Caught me out first time.

[Trahald]

Easy enough... i'll update shortly..

for the time being.. here is the rule as far as structure protection causing desync

will generally need a positive delay (no minus sign) .. use the audio delay as guidance.. a positive delay will delay the start of the subs by x milliseconds. this will effectively lower the times.

a negative delay will move the virtual START time backwards by x milliseconds , this will have the effect of raising all the times.
i chose this behavior to mimic audio delay correctors like delay cut.

[Trahald]

ok 0002 is up.. just cosmetic changes. advises delay is in Milliseconds and explains what effect the delay will have on the timecodes.

[Master Yoda]

Sweet i'll give this new tool a bash. Completly forgot about fun with dick and jane. Cannot remember though, after running through ripit4me and fixvts do i need to demux by vobid in dif4u ?

[Trahald]

i heavily recommend vobid demux on bad sector protection disks. that will hopefully elliminate the need to fix the delay on the subs. i did click by pgc demux and the subs were late and the audio was early. hopefully code can be added to default dif4u to vobid demux on sector protected disks, or any vts with short cells to start off the pgc. disks like "The Stand" also end up with sync issues due to stills at the beginning of the disk.

[Master Yoda]

Well when i originally done fun with dick and jane i done a vobid demux and the audio was fine but the subs was out.

[Trahald]

yeah.. im trying click with vobid demux to see.

well.. either way with the tool you can fix the delay.. im gonna take a look at vsrip after this is done

[Trahald]

... got the same issue you did.. the audio is fine now.. but subs out of sync (correctable with subtitle delay fixer)

time to look at vsrip.. if the audio demuxes ok.. then the subs should too.

[Master Yoda]

Cool, so i just vobid demux then use the delay fixer to correct the subs. Will give it a bash in the next couple of days.
