Changing the volume of selected audio strips in Blender VSE

To set the desired volume for multiple audio strips at once in Blender VSE, select them, then in the Properties panel, in the Strip tab, in the Sound section, type the desired number in the Volume field, hold down the Alt key, and press Enter. Holding the Alt key changes the volume for all selected strips; if we don’t hold it down, the volume will only change for the currently active strip. We can also change the volume for all selected audio strips at once using the Blender Python API.

Automatically muting strips added to Blender VSE

When creating videos in Blender VSE, it’s often necessary to separately create a silent video sequence and only then overlay separately prepared audio tracks onto the edited video stream. However, when adding a video strip to VSE, it is added along with its audio track, with the audio also connected to the video. Separating the audio and video tracks is not difficult, but it takes time. Let’s write a small script that will automatically detach the audio from the video in a strip added to VSE and completely delete the original audio track.
