  1. Here's my issue:

    I'm trying to convert a video file (.mkv) with DTS audio to another .mkv file with AC3 audio. Of course, I can use a software such as MKV video converter, but it will only process the video file as a whole; which will take around 2 days for a 15 Go video file...

    Here's how I am progressing:

    1 - I used tsMuxeR to extract the DTS audio file from the video file...the extracted file is a .ts extension.
    2 - Then, I used xVid4PSP 5.0 to convert that audio file from the DTS format to the AC3 format...it created an audio file with a .ac3 extension.
    3 - Here's where I get stuck: How can I add that .ac3 audio file back into the original .mkv to kinda "overwrite" the old audio format (DTS)?

    Audio is a lot faster to process conversion-wise rather than converting the whole video including all the tracks...

    Does anyone have the required knowledge to help me out?

    Thanks!

    I tried that already, but it will create either a .ts file, a .m2ts file or a blu-ray file, but there's no option for a .mkv file....

    No you didn't try it already...

    It can only export mkv, not other formats

    mkvtoolnix = mkvmerge NOT tsmuxer


    another method

  5. So, should I choose the .ts format?

    I think you're confused with the programs

    there is no .ts format option in mkvtoolnix

    if you already did your conversion to ac3 (i.e you finished your steps 1 & 2 in your original post), follow the steps in post#2

    if you want to start all over again, try popcornhour mkv audio converter in the link above

    O use EZmkvDTStoAC3v1.1 to do that. Simple and fast.

    Awww Geez! Yeah I was a bit confused; I thought you were talking about tsMuxeR...I downloaded MKVtoolnix and am currently converting it; will get the results in a couple minutes...

  10. Thanks everyone! All of your options will be evaluated for sure. I didn't expect to have as much support as that.

    Thanks again to everyone on this post

    What I do is de-mux the mkv with MKVcleaver into it's streams. I insert the DTS stream into DAudioK and convert the DTS into AC3.

    Finally, I reinsert the streams I want back into mkv format with MMG (from MKVToolNix). Usually I also re-insert subtitles in the form of SRTs into it as well. To get the SRTs I use Suprip.
