Working with Video Files

Peak Pro 7 on the Mac allowed you to open a video file in a floating window alongside the audio editor.

You were able to edit the audio with the video playback (as reference) and save the audio to the video file WITHOUT needing to convert or re-export.

I haven’t found any audio editor that does this as standard and I am confused as to why audio editors don’t offer this.

I would love to see Audacity include this feature as many Audio Engineers are often working with video and need to make small audio changes ie. fixing a fade-out or making gain changes without the need to go back to their DAWS just to make these minor adjustments.

please please PLEASE include this. I’m sure I won’t be the only audio guy who appreciates this feature as a massive time saver.

Thanks kindly,


Audacity will be happy to open up the sound track of many different video formats—even more if you install the FFMpeg libraries, but you will need a video editor to put the corrected sound back into the video file.

I am confused as to why audio editors don’t offer this.

Because they’re audio editors. We can just barely keep up with sound and audio editing questions here on the help forum. Can you imagine the support problems if we had to start offering video help, too?

“My MPEG-4 video file got larger after editing the sound track in Audacity. Why is that and can you make it the same size?”

“My 3:2 pulldown film transfer to NTSC Video doesn’t cut on the video boundaries when I edit the sound in Audacity. Can you help?”

I didn’t just make those up. I’m a registered elf on the Final Cut Pro User Group.


You missed the obvious video cross. Audacity doesn’t have Mark-In and Mark-Out. I would kill to have those two video tools in the Audacity kit.


Forgot an important prodlem. One desperation method of preparing video when you’re running out of room is to send the sound as Dolby 2-Track. Dolby is a paid license. Audacity is free.


Peak Pro by Bias, was the major part of Peak Studio. It was expensive software (around $600 in 2012). There was a reason for it being so expensive - the development costs of such complex software is extremely high. The company (Bias) went bust in 2012.

Audacity was developed by enthusiast volunteers over a period of 20 years, until it was acquired by Muse Group in 2020. The creation of such a powerful audio editor by a group of unpaid volunteers was an incredible achievement, representing hundreds of thousands of hours of work.

The reason that Audacity does not support video, is that the developers have all been working to produce an “audio” editor. If someone wrote the necessary code to allow Audacity to play video alongside the audio editing, then I expect that it would be happily added to Audacity - but no-one has.
