Common questions.

What kind of videos is Motionlark for?

YouTube explainers, tutorials, reviews and solo video podcasts. The first version works with one speaker and one camera.

What can Motionlark edit for me?

It suggests cuts for long pauses and possible filler words. You can add word-timed captions and automatic gentle zooms, then review the result. Your original recording stays untouched.

Can I use my own B-roll?

Yes. Add your video clips and describe what each one shows. Motionlark finds spoken moments that match those descriptions. See a clip's first frame, preview the spoken moment, then choose whether to place it.

Does my footage have to be uploaded?

No. Your recordings stay on your Mac. You choose whether to share text with optional online AI.

Can one recording become YouTube Shorts?

Yes. Choose a moment from your recording, adjust the vertical frame, add captions and export it as a separate clip. Your main edit stays unchanged.

Where can I download it?

The Mac installer isn’t available yet. Check the download page for availability and system requirements.
