Cutaway can make new media for your video from a short description:
The AI voiceover window with ElevenLabs, fal.ai and This Mac (free) to choose from, the words to say, a voice, and a preview player

Before you start: add your key

ElevenLabs and fal.ai are AI services you sign up for yourself. Cutaway uses your own account, so you pay them directly for what you make. (Your Mac’s own voices are free and need no account.)
1

Get a key

  • ElevenLabs: in ElevenLabs, open Developers → API keys and create a key. Give it access to Text to Speech, Sound Effects, Music and Voices (read).
  • fal.ai: in fal.ai, open the dashboard → Keys and create a key.
2

Add it to Cutaway

Open Settings → AI generation, paste the key, and press Save. Press Test to check it works. This doesn’t use any credits.
Settings, AI generation tab, with ElevenLabs and fal.ai keys saved and connected
Your key is kept in your Mac’s keychain. It is never put in a project or an export. Only what you type for a generation is sent, to the service you chose.

Make a voiceover

1

Put the playhead where the voice should start

The voiceover is added there.
2

Press + on the audio row and choose AI voiceover…

3

Choose who makes it

ElevenLabs, fal.ai, or This Mac (free).
4

Type what it should say and pick a voice

Press Generate, then listen to it in the window.
5

Keep it

Not quite right? Change the words or the voice and press Make another. Happy? Press Add to timeline.
Want to use your own voice instead? See Record a voiceover.

Make music or a sound effect

  1. Put the playhead where it should start.
  2. Press + on the audio row and choose Generate music… or Generate a sound effect….
  3. Describe it, for example “calm lo-fi beat” or “a soft whoosh”.
  4. Set the Length. For music from ElevenLabs, leave Instrumental on so there’s no singing over your voice.
  5. Press Generate, listen, and press Add to timeline.
Generated music is added like any other music: quieter, and lowered while you talk. See Voice, music and sound to change it.

Make a picture or a short video

  1. Press + on the video row to add it as its own clip, or on the text & effects row to put it over your footage (like B-roll).
  2. Choose Generate an image… or Generate a video….
  3. Describe it, and choose a Shape: Wide, Tall or Square. Videos can be 5 s or 8 s long.
  4. Press Generate, look at it, and press Add to timeline.
Nothing is added until you press Add to timeline, so you can try a few versions first. Each try uses credits from your account.

Choose the fal.ai models

Settings → AI generation → fal.ai models lets you pick which fal.ai model makes each kind of media. The defaults are inexpensive. You can paste any model id from fal.ai’s model list that takes a text prompt, or leave a field empty to go back to the default.
