What is an AI video editing agent?
An AI video editing agent goes beyond suggesting edits or generating a finished render. It can understand your footage and instructions, decide which editing steps are needed, apply those changes to the video, and respond to follow-up requests. In Cubix, those changes remain editable on the timeline.
From intent to timeline.
- 01
You describe the outcome
“Make this tighter and add some energy without over-editing it.”
- 02
Cubix understands the footage
- Speech
- Scenes
- Pacing
- Important moments
- Existing edits
- 03
Cubix builds the plan
- Remove 4 long pauses
- Tighten intro
- Add 3 punch-ins
- Caption key section
- Add B-roll to explanation
- 04
Cubix applies it
Cuts, captions, punch-ins and B-roll land on the timeline as ordinary edits.
Every AI action becomes a normal edit you can inspect, change, undo, or refine.
What the AI editing agent actually does
- 01
Understands the footage
Analyzes speech, scenes, pacing, structure, and important moments before deciding what to change.
- 02
Plans the editing steps
Turns your request into a sequence of real editing operations rather than applying one opaque effect.
- 03
Applies edits to the timeline
Cuts footage, adjusts pacing, adds captions, reframes, places B-roll, and uses other Cubix editing tools where needed.
- 04
Keeps working with your feedback
Ask for another change, make the edit subtler, undo part of it, or give the agent a completely new direction.
How to edit a video with an AI agent
- 1
Upload your footage
Add the video or clips you want Cubix to work with.
- 2
Describe what you want
Ask for an outcome in normal language. You can be specific or simply explain what feels wrong.
- “The intro feels slow. Tighten it.”
- “Turn this into three vertical clips.”
- “Remove the awkward pauses and add clean captions.”
- “Make this feel more energetic, but keep it natural.”
- 3
Review the plan and edit
Cubix works out the editing steps, applies them to the timeline, and shows you what changed.
- 4
Keep refining
Ask for another change or adjust anything manually before exporting.
Ask for the result. Not the tool.

- Remove silence
- Ripple delete

- Reframe 9:16
- Add captions
- Search B-roll

With Cubix
You say:
“This feels slow. Make it tighter and easier to watch.”
Cubix works out which tools are needed.
Traditional editing
You need to do:
- Find highlight
- Cut clip
- Reframe
- Caption
- Adjust framing
With Cubix
You say:
“Find the three best moments and turn them into vertical clips.”
One instruction, several editing operations.
The agent edits. You stay in control.
Cubix can make the first pass and handle repetitive editing work, but it never turns the result into a locked black box.
Scope
How much of the project the agent is allowed to change.
Pacing
How aggressively it tightens the edit.
Style
How far the finish should go.
Steer these in conversation. They are directions you give the agent, not a locked preset.
Specific instructions
- “Keep this section untouched.”
- “Use fewer zooms.”
- “Don’t remove pauses after questions.”
- Change any cut
- Undo an AI edit
- Restyle captions
- Move or replace B-roll
- Adjust pacing
- Continue manually on the timeline
What can you ask Cubix to edit?
Clean up a recording
Remove pauses, retakes, dead sections, and distractions.
Polish a creator video
Tighten pacing, add captions, and punch in on the lines that carry the point.
One edit becomes a conversation.
You do not need to restart the project every time your direction changes. Keep talking to Cubix and refine the same edit.

AI video editing agent FAQs
An AI video editing agent understands footage and editing instructions, plans the steps needed to achieve the requested result, applies those edits, and can continue refining the video through follow-up requests.
Many AI video tools automate individual tasks or generate a finished output. An editing agent can coordinate multiple editing actions from one instruction and continue responding to feedback as the edit evolves.
Yes. You can give Cubix instructions in normal language, from specific requests like removing pauses to broader directions such as making an intro tighter or turning footage into shorter clips.
No. Cubix can analyze the footage and use the context of your request to determine where an edit should be applied. You can still provide timestamps when you want precise control.
No. You can describe the result you want instead of naming the editing tool or technique. Cubix works out which editing operations are needed.
Cubix can plan and apply edits directly to the project timeline, where you can inspect and adjust the changes before exporting.
Depending on the footage and request, Cubix can use capabilities such as cutting and pacing, captions, clipping, reframing, B-roll, audio cleanup, zooms, transitions, and other editing tools available in Cubix.
Yes. You can continue the conversation and ask for an edit to be stronger, subtler, different, removed, or replaced.
Yes. AI changes remain on the same editable timeline, so you can continue editing manually at any point.
Cubix can work with different kinds of recorded footage, including creator videos, podcasts, interviews, YouTube videos, screen recordings, and short-form content.
Cubix is primarily built to edit footage you already have. The AI editing agent analyzes and transforms your recorded media rather than replacing it with an AI-generated presenter or avatar.
