Rip plays as if its in fastforward ?

[Ghidorah]

Hi folks...new member here so please be gentle!
Ive been using MakeMKV to rip my BDs onto my external drive to play using the Mede8er 1000x3d. Ive had problems when i ripped a couple of the Criterion Collection discs in that the play back is constantly running too fast. The whole thing runs as if its on fastforward. Some of the other Rips ive done are fine. Any help?
Thanks

Does it work ok on your computer? with for example vlc, mpchc.

[Ghidorah]

Yes, thanks..its fine on Media Player and VLC

[Baldrick]

Post the full details from a mkv that works ok on your Mede8er and from a mkv that plays fast. Use mediainfo, view->text and copy everything.

Here's the info on the faulty one...

[Ghidorah]

Anyone able to help with this?

[hello_hello]

Given it's an issue relating to your hardware player it might pay to ask the question here:
http://www.mede8erforum.com/index.php?PHPSESSID=7p32h41d763tru373mcc0kosp3&board=112.0

Are you using the latest firmware?

[Baldrick]

You could also try remux(no video reconversion) to a mp4(reconvert the audio also) with mkvtomp4 and see how it works.

Yep, thanks. Firmware is the latest. Tried the Mede8er forum but im not getting a lot of answers. The weird thing is the 2 faulty rips are both Criterion Collection discs. Is there something about them thats different from others? I know they're Region locked but ive done a Region locked disc before without a problm

Cheers i might try that..id really like to know whats causing the problem though.

[hello_hello]

I recall years ago having a similar problem playing some AVIs using MPC. If I removed the audio they'd play normally, but with the audio they'd play at double speed. I think it was something to do with the sampling rate of the audio being read incorrectly, or maybe the audio was muxed into the AVIs incorrectly...... I can't remember. I do recall MPC displayed the wrong duration..... probably double what it was supposed to be.

You could try using MKVMergeGUI to open a problem MKV and resave it with just the video or just the audio etc to see if you can determine if a particular stream is causing the problem.

Along the lines of Baldrick's suggestion, you could also try extracting the individual streams with MKVCleaver and using those to make a new MKV with MKVMergeGUI to see what happens.

My money's on it being something to do with the audio. Do all the other "problem" MKVs have the same type of audio?
I'm not sure I have any MKVs with PCM audio so I made a multichannel wave file and muxed it into an MKV. When I opened it with MediaInfo it looked like this:

Format : PCM
Codec ID : A_PCM/INT/LIT
Duration : 6mn 19s
Bit rate mode : Constant
Channel(s) : 6 channels
Sampling rate : 48.0 KHz
Bit depth : 16 bits
Default : Yes
Forced : No

Not much different to the MediaInfo info from your files, except your "problem" MKV doesn't have any mention of the number of audio channels. The rest do.
I Googled a little and while I didn't find a problem the same as yours, the stuff I read here would have me looking at the PCM audio first, although I'm just guessing. http://www.makemkv.com/forum2/viewtopic.php?f=8&t=2530
You could try converting the audio to another format to see what happens.

If you work it out can you post back to let us know what it was?

[Ghidorah]

Thanks very much for your help.I'll try a few audio things and post back. Cheers

[Ghidorah]

hi just wanted to say that i disabled the audio track and re-muxed it and you were absolutely right...It played at the right speed! At least i know what the problem is now. I guess what i need to do is figure out where to go from here. I want the quality to be as good as possible so i guess i need to somehow convert the audio and get it back onto the original video track.
BIG thanks for the help.

[hello_hello]

If you don't have a preferred audio conversion program, give TAudioConverter a spin. It might pay to check you end up with the correct number of audio channels (ie the same number as the audio on the disc) as if MakeMKV has done something odd when muxing it could confuse a conversion program too.
If you convert from wave file to wave file you shouldn't loose any quality. Or convert to a lossless format.

You could even try simply extracting the audio with MKVCleaver and adding the extracted version back to the MKV with MKVMergeGUI. That might fix any problems caused by muxing originally.
