Converting Mkv results in out of sync streams.

[house3272]

I bought Adobe Encore recently because I got tired of using pre-made menus from various programs.
Everything's fine until I tried using an mkv video because I wanted to play around with multiple audio streams.

Realizing how little I know it seems, I tried to just figure it out.
According to mediainfo....

...the original mkv is 23:46 long, as well as each individual stream.

When I used mkvcleaver, since Adobe hates mkv, the 4 streams came out.....well,
the avi is 19:30, the two stereo aac's 3:21:14, and the 6 channel one @ 5:40:41.....
I assumed it was because of the multichannel for the audio, but that's more than 8 times the length of the original.
Totally lost.

Upon importing it into Premiere, the audio tracks were reading 23min again. But the video was still at 19.
It's all there, just playing at a greater fps or something.

Similar problem happened when I used AVStoDVD, both just getting the streams and muxing into a m2v.


Thus I conclude I just don't know what the hell I'm doing anymore (and I felt so good working avi's and mp4's a day ago)
Any Help explaining what I seem to be missing is appreciated.

Why don't you use AVStoDVD to convert the mkv to DVD elementary streams (1 m2v and 3 ac3) and the import them into Adobe?

Check you original mkv again, I think it's frame rate mode isn't constant.
Try Handbrake program, it can convert VFR to CFR(constant frame rate), I change CLI program of my GUI program because of this problem too.

I tried that of course, and the video is fine (seemingly), but then the audio lags.
1~3 seconds at the beginning and end, but like a whole minute in the middle.
Yea, no idea.

Ah yea, as far the video, I think that was the problem. Thanks! Totally forgot about Handbrake.
As far as audio goes, what format is less...problematic? Flac?

Do you still have the AVStoDVD project log file? Could you please post it here?
