What this does
Triggers automated AI video editing by sending plain English prompts to the Cubix AI Agent.
Start with pacing and captions — 'tighten the pacing and add captions' — because those two change how a video feels more than anything else. Add the look and the motion once the cut is right.
How to do it
Follow these step-by-step instructions in Cubix.
Open the Cubix AI Chat Box
In your project workspace, click the AI Agent chat box at the bottom of your screen and start typing.
Enter an editing prompt
Type a descriptive request telling Cubix what edits you want to apply to your video.
Enter prompt interface in Cubix AI Agent.
Read what it says it did
Cubix reports the actual changes — how much it removed, how many cuts it made, which caption style it applied, and the timestamps of anything substantial it took out. Read that before playing back; it tells you where to look.
Watch it back
Play the section it changed. The first result is a draft, and judging it as a draft rather than a final edit is what makes the next step quick.
Correct anything that missed
Describe what was wrong rather than repeating your original request. A correction is understood against the edit that already exists, so everything you liked stays exactly as it is.
Pro Tips for Best Results
- Everything Cubix does in one reply undoes together, so one Ctrl+Z (Cmd+Z) takes back the whole change rather than unpicking it piece by piece.
- Ask for two or three related things at once. Asking for ten makes the result harder to review and more expensive to undo.
- If you want a restrained result, say so. 'No shake, no flashes' is a faster route to a professional finish than any positive instruction.
- Point at a moment by quoting yourself — 'where I say let me show you' — rather than by timestamp. It is more precise and it survives the video being re-cut.
- In a hurry? Quick Build in the Extras panel does a one-tap trim plus captions, with options for the caption sequence, its look, and how much of the opening to skip.
You do not have to use the chat at all. The same passes are available as one-press buttons on the quick edit rail, and anything the agent does can also be done by hand on the timeline.
