    I've already tried using GotSent, but it keeps crashing. And when I convert it with Xilisoft, it just says ''failed'' for some reason. Worked fine before, but some loss of quality though.

    Please help me, appreciate it!

    You might try using handbrake.

    Thank you for all the replies. I am trying the handbrake and it is taking long time. I searched for my self some time and found this ''HDConverterToX'' and it had a fine output but the video was going in slow motion while the audio was fine. This method took really long time. Thank you for quick answers!

    Handbrake does take a while, but has good results.

    But you are re-encoding with handbrake , and losing quality (unless you use lossless crf=0, but then you get huge filesize)

    If you re-wrap , you lose no quality and only it takes a minute or two. All you are doing is taking the video & audio and copying them into .mp4 container - much better than re-encoding

  7. I agree with poisondeathray. Use Yamb to take the video and audio streams out of an MKV container and put them into an MP4 container. It's fast and there's absolutely no change in quality.

    I haven't tried Yamb but AviDemux can also convert MKV to MP4. However, a true MP4 should really have the audio converted to AAC instead of AC3.

    avidemux2_cli.exe --load "%~n1.mkv" --output-format MP4 --save "%~n1.mp4"

  9. MP4 officially supports AC3. So it's just as "true" in MP4 as AAC. Granted, being new, it's less common and some programs/devices don't work with it.

    Not clear what OP is wanting to do.

    Is no recode the goal?

  11. Well, he did say "without losing quality".

    Then remux the container.

    That doesn't guarantee anything will play it.

    You could try ffmpeg:
    ffmpeg -i originalfile.mkv -vcodec copy -acodec copy newfile.mp4

    which will copy the streams without re-encoding.

    Yamb doesn't support .mkv extension. And Handbrake is working perfect! Great result, but takes a while!

    Maybe you need an update? Or maybe Haali mkv splitter?

    I have the newest version. I doesn't support .mkv. It looks like your one is a very old version by watching the screenshot you provided.

  17. I'm using the 2009-06-29 version (2.1.0.0 beta 2) which is the latest version, as far as I know.

    I suspect you didn't elect to include MkvExtract when you installed Yamb.

    Yeah, you had right, I didn't install the MKVextract, but now, when I add my files in there, it just gets an error and finishes...

    What does the error say? post the log file

    You can try using mkvextractgui , extract the raw streams, then import them into yamb
