Title: Extracting audio ONLY from MLV
Post by: saf34 on June 23, 2018, 03:07:11 PM

Hi all, I had a little look around the forum but can't see an immediate way to do this.

I'd like to quickly extract the wav audio from my session's MLV collection.

The reason? After I did my 24-hour batch MLV -> DNG using mlv_dump, I have audio missing from a bunch of files (but not all). So I need to investigate.

Is there a command-line tool for doing this? I half wondered if there might be an option on mlv_dump but I can't see any.

Any help really appreciated.

mlv_dump cannot handle this.
you could write into a raw file and delete that file afterwards, or use mlvfs (https://www.magiclantern.fm/forum/index.php?topic=13152.0) and just copy the .WAV files.
i use mlvfs for everything i do with MLV files and mlv_dump only for debugging purposes

MLV App can export also "Audio only" as wav. Import clips, mark all (Ctrl+A), set export codec to "WAV (Audio only)" and export.

Thanks to both. MLV App worked out well for me.
