Does KillAudio() just mute the audio or does it remove the audio layer entirely?

[Katie Boundary]

This distinction is kind of important for projects that require the existence of an audio layer, but don't require it to contain any actual audio.

Remove the audio layer, like if you open only the video with xVideoSource().

If you want only mute it use Amplify(0)

When I render through a script which includes Killaudio() and then import the resulting file into my NLE, there is no audio layer. Mediainfo confirms this.

I think you should be able to do this test yourself doing the same thing I describe.

If you need a null audio layer, I think something like MergeAudio should be able to do that, although others who have actually done that should chime in to confirm that this will work.
