FAQ
Frequently asked questions
Quick answers about track limits, stereo panning, ducking compatibility, and non-destructive editing.
How many audio tracks can be added to a KineMaster project?
Every KineMaster project supports (nearly) unlimited audio layers, including voiceover, music, and effect tracks.
What is the difference between Mute and Auto Volume?
Mute silences an audio track. Auto Volume balances the overall volume of the track to match other audio tracks' volumes on the Timeline.
Can I pan audio to the left or right channel?
Yes. The Mixer tool includes a pan control for the left and right channels to position audio anywhere in the stereo field.
Is the mix applied non-destructively?
Yes. All Mixer settings are non-destructive and can be adjusted at any time before saving a project as a video.
