| + Frame with size 438
| + Reference block: -42.000ms

What you're looking for are lines similar to these but with "track number 3" (I'm guessing that track number 3 is the subtitle track, if not search for "track number n" where n is your subtitle track number). If there are such lines with the timecodes that match the ones on your .srt file (entries 63-67) then the subtitles are muxed correctly.

You can also compress report.txt and send the compressed file to me (moritz@bunkus.org) so that I can take a look at it.

IT WORKS!!

BUT, actually MPC shows only the Language name given by LCID code, not the "name"-tag containing individual data like "comment by Ridley Scott", shouldn't the (any) player show this one as well in the stream-select-dialog?? Otherwise I see only "English" 2 times, quite useless.

Which name? Could you send me your .idx file, please? (moritz@bunkus.org)

Thanks.

Wow, MKVToolnix / Matroska continues to become more and more versatile. Kudos to Mosu, Gabest, and the rest of the team.

Is there any guideline for what kind of compression ratio can be achieved with zlib compressed vobsub's ?

[Human_USB]

E-Mail sent..... hope you get it.

Mosu, why the IDX file?

I'm talking about the "name"-tag of audio-streams. Sorry that I didn't write this in my last post clearly.

Your GUI for mkvmerge shos a tooltip over the name-tag that it an be used for things like "director's comment" so I did so, but no players shows this at all.

Thanks
Raist

P.S. Do you still want my IDX-file?
P.P.S. Just tried to convert several OGM + IDX into MKV, noticed that it doesn't work with one movie where there is only one sub inside the .SUB, under stream 8.

You will usually get a reduction to 40-50% of the original size:

10338304 2003-10-29 18:09 vs/ally1.sub
 6740374 2003-11-10 19:15 nocomp.mkv
 4576954 2003-11-10 19:15 zlibcomp.mkv

Explanation: VobSubs, when extracted with VSRip, still contain a complete MPEG PS (or was it TS?). Additionally this stream uses padding up to 2kb block boundaries wasting a lot of space (well on a DVD it doesn't matter, but for us it does). We only need the SPU packets so we discard the MPEG PS. The resulting SPU packets are put into a Matroska file either uncompressed (nocomp.mkv) or compressed with zlib at its best compression setting (zlibcomp.mkv).

So just by discarding the SPU packets we gain approx. 35%. The SPU packets themselves can be compressed further down to ~66% of their original size.

I haven't done extensive checking but other streams should result in similar numbers. This VobSub contains of eight streams for a 42minutes episode of Ally McBeal.

Uuups. I though there was some obscure "name" tag in the .idx for the VobSub file which mkvmerge did not convert to a Matroska track name.

No, I don't need the .idx then

Sorry, I don't know enough about Windows, DirectShow etc. in order to place blame. It's either the splitter's or the player's fault, obviously.

Is this .idx+.sub small? If so, can you send it to me please? moritz@bunkus.org

Thanks.

Hi Mosu,
using mkvtoolnix 0.7.5, I got the following error while muxing a XviD video, a vorbis audio and a VobSub file:

Any idea of what's going on ?
BTW, thanks for your great tools !

Pasqui.

EDIT: the failure seems related to the zlib compression because the multiplexing was successful without compression.

EDIT2: the error appears randomly: after several tries and failures at different percentage done, I successfully muxed the file with subtitles compressed.

@Mosu


Did you get the file?

Unfortunately mkvmerge does not print any error at all, it just exits with a strange exit code. The last line is from mmg which just tells you that mkvmerge died. So I have no idea what's going wrong.

Ah, that's interesting. Could you please send me those vobsubs so that I can try to recreate this problem? moritz@bunkus.org

Thanks.

Yes. Your Matroska file contains a VobSub subtitle track, but the stuff you posted above is from a .srt file. I assume that the .srt was made from the same VobSubs so that the timecodes match.

Anyway, the report.txt you sent me DOES contain the entries for the timecodes you haven't seen, so I'd say that mkvmerge has done its job correctly and that it's a playback problem.

why Virtual Dub Mod don't open mkv file created with mkvmerge of mkvtoolnix 0.7.5?

(i haven't tried with previous version)

[tiki4]

I think this was posted in the beginning of this thread:

VirtualDubMod was compiled against a version of libmatroska that doesn't yet support the new lacing scheme mkvmerge 0.75 uses. VirtualDubMod has to be updated.

Exactly, but I think Cyrius did release a new version yesterday. Anyway, VDubMod will probably never handle VobSubs.

Exactly.

I also said that it won't be able to edit matroska files using encryption/compression.
And I think it won't edit files with vobsub tracks either.

Really ? Where ?
There is no released version IIRC. Changes up to VirtualDub(-MPEG2) 1.5.9 are in the CVS, but we still need to update a few VirtualDubMod specific things.

Concerning the Vobsub tracks I don't know if it will ever be supported.

@Mosu

Could you please look at those threads http://forum.doom9.org/showthread.php?s=&threadid=64649 and to http://neuron2.net/ipw-web/bulletin/...hp?p=2510#2510

and decide if you're willing to add timecodes import option in mmg GUI since it is real pain to experiment with VFR and having to type everything so many times?

After parsing Telecide decision log on the basis of some parameters vfrparser produces timecodes as per your specs.

First example of TNG clip

# timecode format v1

assume 29.97

#Consecutive frames threshold 2

0,293,29.97
294,296,29.97
297,1138,23.976

second example of TNG clip

# timecode format v1

assume 29.97

#Consecutive frames threshold 1

0,0,23.976
1,293,29.97
294,294,23.976
295,296,29.97
297,1138,23.976

I also do hope that syntax 294,294,23.976 is correct. If not I will limit simillar-type consecutilve threshold to minimum of 2 (like it is in first example).

You mean a simple file selection entry for the --timecodes command line switch? Sure, no problem.

This is correct - this would mean that there's exactly one frame with a duration of 1/23.976 seconds.

where can i read about "variable frame rate" and for what can be use it?

It has something to do with changing the frame rate of the movie when changing the audio stream (from 23.976 fps audio stream to 25 fps audio stream)? (is this possible?)

Thanks

i couldnt find the first thread where 120fps videos were discussed but here are some threads:
