We are in the process of uploading a lot of video content to Datocms. We love the video editor, but we really need the ability to remove the audio track so our videos can play silently even when umuted. A feature to remove audio would be very useful in the video editor.
Thanks for the suggestion, @TD_Travel! Please remember to vote on it in the upper left.
In the meantime, you can easily do this (prior to uploading) with the free command-line tool ffmpeg:
ffmpeg -i input.mp4 -an -c:v copy output.mp4
That will remove the audio track from a file for you in less than a second, and as a bonus, will make the video quicker to upload since it no longer has audio data.
