MP4 to MKV

[hardy]

I have been using MKVToolNix but the file will not play afterwards. Is there a program like MKVCleaver where I can basically extract the video and audio. Then I can load everything into mkvmerge and go from there.

Or, if there is a more easier way to accomplish this... No re-encoding, just a simple container switch

Any other alternatives?

You can use MY MP4BoxGUI to de-mux.

[hardy]

I just want to strip the video & audio from the mp4 container.

[videobruger]

That what de-mux does. Unless I misunderstand.

[hardy]

is it better than avidemux?

Can you post the video details from mp4. Use mediainfo, view and text. Maybe some strange format that mkv does not support...

I can't see why it wont work with mkvtoolnix.

But try avidemux. Just choose video and audio copy, format mkv and save.

[hardy]

I'm pretty good with command prompt, maybe I can work some magic with cmd, for a simple container change
Kind of like how I use CMD & eac3to for stripping certain audio

[videobruger]

CMD:

ffmpeg -i yourfile.mp4 -codec copy yourfile.mkv

[hardy]

CMD:

ffmpeg -i yourfile.mp4 -codec copy yourfile.mkv

so basically rename the file with that technique
Would I have to put the MP4 file in the same folder as ffmpeg?

[videobruger]

What you do with the command ir re-mux the video/audio content without re-encode.

Would I have to put the MP4 file in the same folder as ffmpeg?

Yes - unless you place ffmpeg.exe in your path.

There is a way to change the container using the Video To Video Convertor without re-encoding. Describing how to do so takes a bit of time.

You drop the file into Video To Video. You chose Direct Stream Copy. Go over to the side panel and notice where it says Output Container click on where it reads "Same As Source" notice a little down arrow with a bunch of container options comes up. Chose the one you want and press Ok. Click on "Convert" and you will notice almost instantly it has completed the task. Check the output folder for the file and test it to see if it is to your liking. I do this with success for when I want to play .flv files to .mp4 files which my LG Blu Ray player plays. I find if a file is a .flv I can't fast forward or pause, but if I change the container to .mp4 it usually lets me; I referring to the Blu Ray player.

Something else that is useful is that you can do it in batches if you have a whole bunch of files that need to be done. I would keep the originals though until you test all the output files just in case. It is better be cautious.

thanks videobruger
ffmpeg worked like a charm

ffmpeg -i input.mp4 -vcodec copy -acodec copy output.mkv
