Well, the first mistake was that I have bought idiotic action camera recorder Tachyon XC HD. This buggy and very low-quality camera makes .MOV files with some strange streams, that almost no software is able to edit. I have lost maybe 30 hours of research how to convert the .MOV files from the camera to something editable.
I am able to convert the .MOV file video track to .MP4 file via VLC player ("keep-original-video-track" option in "video codec" window). I am able to get the audio track from the .MOV file. But I am not able to join video and audio file together. I have maybe 40 of recording so I would like to use command-line.

Can someone advise me how to split original .MOV file to separate video and audio stream, transcode audio (leave video as is) and join it again to different container (MP4). I thing it should be possible to do it in one command line.

The following command is able to change a container to .MP4, but the resulting file kills VLC player and other software is not able to play it:

Code: Select all

"c:\Program Files\VLC\vlc.exe" f:\DCIM\100XCVID\VID_0024.MOV --sout="#standard{access=file,mux=mp4,dst="e:\scratch\vid24.mp4"}"

The following command takes only video track and works fine, but the resulting file is without audio ofcourse:

Code: Select all

"c:\Program Files\VLC\vlc.exe" f:\DCIM\100XCVID\VID_0024.MOV --no-sout-audio --sout="#standard{access=file,mux=mp4,dst="e:\scratch\vid24.mp4"}"

I am using Windows XP with all patches to the date of this submission with VLC player 2.0.7.

Try to transcode the audio, not discard it.

The following command will make a movie file thats kill VLC player when trying to playback:

Code: Select all

"c:\Program Files\VLC\vlc.exe" f:\DCIM\100XCVID\VID_0024.MOV --sout="#transcode{acodec=mp3,ab=128,channels=1,samplerate=44100}:standard{access=file,mux=mp4,dst="e:\scratch\vid24a.mp4"}"

When leaving out "samplerate=44100' it will make correct file even with audio, but Adobe Premiere imports it only without sound. I think that the reason for it is that MP4 container cannot feature MP3 audio.

When I use MP4 AVC audio codec instead of MP3, the VLC Player writes "VLC could not open the encoder".

Code: Select all

"c:\Program Files\VLC\vlc.exe" f:\DCIM\100XCVID\VID_0024.MOV --sout="#transcode{acodec=mp4a,ab=128,channels=1,samplerate=44100}:standard{access=file,mux=mp4,dst="e:\scratch\vid24a.mp4"}"

Do you have idea how to make proper MP4 movie file?

Try acodec=mpga

Posted: **17 Jun 2013 21:19**

When using

Code: Select all

"c:\Program Files\VLC\vlc.exe" f:\DCIM\100XCVID\VID_0024.MOV --verbose=2 --file-logging --logfile=vlc-log.txt --sout="#transcode{acodec=mpga,ab=128,channels=1,samplerate=44100}:standard{access=file,mux=mp4,dst="e:\scratch\vid24a.mp4"}"

the VLC Player starts and die immediately producing no file at all. I tried to change the bitrate, number of channels or delete samplerate parameter with no result.

Here is log file generated with verbosity=1

Hey, I am not even able to compress any audio file to MP4A. What's wrong with this command?

I do faintly remember from some old times that VLC player wasn't able to compress AVC audio (is it same as MP4A?) due to some compilation reasons (licence?). I hope that this case is not that sort of problem...

Posted: **24 Jun 2013 13:41**

OK. After a couple of tests on another computer I am closing this topic with result, that VLC Player is NOT ABLE to encode MP4A (AAC). I didn't find a reason why.

Posted: **25 Jun 2013 21:55**

I got it to work.
