How do I extract audio from a video and turn it into an audio file?

I’m making an animatic, and want to know how to extract audio from a video and turn it into a file I can insert into a movie making program.

With ffmpeg installed, you can extract just the audio. Here is a sample command usage:

ffmpeg -i video_file.mp4 audio_file.mp3

You may want to pass through the audio so it's not reencoded. The top answer on this stack overflow article has an example. https://stackoverflow.com/questions/9913032/how-can-i-extract-audio-from-video-with-ffmpeg

And a copy/paste:

ffmpeg -i input-video.avi -vn -acodec copy output-audio.aac

Certainly. ffprobe is also a good command to check what audio codec is in the video

For those not comfortable with a terminal, I suggest VLC. I'm 95% sure it is just using ffmpeg under the hood as well.

I’m trying to download it, but my Chromebook is making the file register as “read only.” How do I fix that?

I don't think ffmpeg works on Chromebooks.

This online converter worked for me.I don't know if there's a size limit; if there is you may have to trim the video first.

If you search "extract audio from video" online you can find other similar options.

What movie making program are you using? You should be able to just put in the video and disable or delete the video track, only leaving the audio.

Use handbrake command line. References available on the web. Ffmpeg would also work

The most user friendly way is to download Shutter Encoder and drag / drop your file into it and select MP3 / Wav from the drop down menu.

If you're comfortable with the command line, you could use a tool like ffmpeg to do this on your own computer. You might need to know the format of the video file and the format that you want to make the audio file, though.
