Help with LOTR extended discs!

[claudiobar]

Hello!
I've finished encoding LOTR II extended; I've have two separate mkv files with the same bitrate but different filesizes. I thought that would be the best way to achieve my goal; after compressing everything this way, just joining them with mkvmerge.

The problem is that audio does'nt match in the second dvd (It does if I play the file separatedly, but not when I join them)

I read in this forums that it has something to do with 15 frames of blackness at the end of DVD 1, or so... a delay of about 510 ms

But: now that I have the files already made; is there any way to join them adding a separate delay to the second disc only? Or a way to delete those frames without affecting the audio stream?

I think I can't do this with the tools I use: mkvmerge, megui's muxer and virtualdubmod (vdubmod can't even display the frames in its screen nor save the file to another one)

Thanks in advance!
Claudio

Are u using the original AC3 or transcoded into MP3/AAC?
If it is other than AC3, then u can set the delay on transcoding.
There are no MKV editors, VDub can open MKV but with prejudice.
Or u can load the file into MKVExtract, export the video as RAW, then use AVC2AVI to mux it into AVI container. Load this AVI into VDub and export the movie in Direct Stream Copy without the unwanted frames. Then reload the trimmed AVI into Yamb and save as MP4, load that MP4 into MKVmerge to export a final MKV.
Or u can encode it again using Trim() in your avs script.

I had the same problem and i used Matroska as well, then i appended the second audio and video from DVD#2 and the delay was exactly -680ms on ALL tracks including the .idx subs, which i used and AAC audio which i transcoded from the original AC3. But the real problem for me were the chapters, which weren't exact after the appending of the tracks, but i calculated the delay for ALL the chapters (78!!!!), which was REAL pain in the ass, but i was clever enough to save the MMG settings and corrected chapters if i decide to do another backup! By the way i have the PAL version so i don't know if it's the same with you.

here's a tip with chapters: pretend they're subs and feed them into a subresync style program. that way you only need the offset...

BTW, why going the hard way of adjusting all those tracks & tracks & other stuff? IIRC, simply trimming those black frames at the end of disk#1 worked quite well for me ... ;)

[Mc Onyx]

I tried trimming first, but i don't know why, it just didn't work, the audio wasn't in sync with delays inserted or without!

Hi!
Thanks all for your answers.
I'm opening the file with virtualdubmod, but.. do you know any way to cut out those black frames without affecting the audio or subtitles streams?
Guess I have to export all the streams out of the file, cut the frames out and import them back?
tnx :)

I've recently made an xvid copy of lotr1-2-3.
For 2, I kept the orinal ac3-5.1 - and the audio synch appeared for the 2nd disk.
I had to duplicate (8 times, for my delay) the the last frame from disk1, in .avs. And the audio problem was fixed.

p.s. I joined the 2 video parts only in the .avs; or you do it with DGindex
p.s.2: can you post which CQM you chose?
