How to Edit a Video with AI: From First Cut to Final Export

Every editor knows how quickly a simple brief turns into a long list of little jobs. Go through the recordings. Pull the takes. Build the sequence. Find the B-roll. Adjust the music. Then work through another round of changes. “Just a few tweaks” has a funny way of filling the afternoon.

Working with an AI editing assistant can take some of that grunt work off your plate. You explain what you’re making, give it a specific editing task, and build on the result one step at a time.

invideo Editor, with its built-in AI agent, works with your footage and instructions to build your edit step by step on an editable, professional-grade timeline. This guide walks you through that process, from briefing the base cut to adding visuals, refining sound and colour, and exporting the finished video.

If you prefer working in Claude or ChatGPT, you can also connect them to invideo Editor through its MCP server and direct edits on the same timeline. See how to connect your AI agent.

How does ai assist in video editing: A step-by-step guide

1. Explain the video you have in mind to your AI agent

Start by telling your AI agent what you’re making, who it’s for, and what you want the viewer to understand. Upload your footage, along with any script, screen recordings or other assets you’ll be working with.

For this guide, let’s use a product walkthrough as an example:

We’re building a two-minute walkthrough for people using this product for the first time. I want to introduce the problem it solves, walk through the setup, and show the main workflow. The tone should be clear and conversational, with enough time for viewers to follow each step. I’ve uploaded the presenter recordings and screen captures.

This establishes the concept. You don’t need to squeeze every editing instruction into this opening brief. You’ll give the agent more detailed direction as you work through the video.

If there are things you already know must stay, mention them now. That might be a particular demonstration, a required disclaimer or an exact line from the script.

2. Build the base cut first

Your first editing request should focus on getting the footage into a coherent sequence.

Your AI agent inside invideo Editor can watch the footage, select the strongest takes, remove retakes and fillers, and assemble a base cut. Give it clear instructions about the order, pacing and material you want to preserve.

For our walkthrough:

Start by assembling the presenter footage into a base cut. Put the problem first, followed by setup, the main workflow, and the closing summary. Select the strongest complete takes and remove failed starts, retakes, fillers and long pauses. Keep every setup instruction intact and leave natural breathing room between steps. Aim for around two minutes, but prioritise a complete explanation over hitting the duration exactly. Leave B-roll, music and effects for later.

The duration gives the agent a target. The instruction to preserve the setup steps explains what matters if reaching that target would mean cutting useful information.

Watch the assembled sequence before moving on. Does the explanation flow? Does anything repeat? Is a section taking too long to get to the point?

Then give the next instruction:

The opening spends too long explaining the problem. Keep the first explanation and move straight into setup. Leave the demonstration and closing summary unchanged.

You now have a sequence to build on. For a more detailed look at this stage, see our guide to creating a rough cut with AI.

3. Add B-roll where it supports the story

Once the base cut is in place, ask your AI agent to add supporting visuals where they help explain what’s being said.

In a walkthrough, viewers need to see the interface while the presenter explains what to do. In an interview, you might want footage of the place, person or process being discussed.

Tell the agent what to show and where it belongs:

During the setup explanation, add the matching screen captures from my uploads. Keep the presenter’s voice underneath and show each action as it’s explained. Return to the presenter for the closing summary.

Timing matters here. A shot can be relevant to the topic but still appear too early or disappear before the viewer has understood it.

If you need additional material, invideo Editor can also source stock or generate B-roll within the project. Specify your preference and whether the agent should use only your uploaded assets.

For an exact product demonstration, use recordings of the actual interface. For an introductory idea, an illustrative shot may be enough.

4. Add music and balance it around the dialogue

With the visual sequence established, tell the agent what role the music should play.

Our walkthrough needs a background track that supports the explanation without competing for attention. A launch promo or travel montage might put the music much more prominently in the edit.

A useful instruction could be:

Add a light instrumental background track. Keep it quiet beneath the presenter and bring it up slightly during the opening and closing shots. Fade it out at the end.

Listen through the transitions between speech and music. Pay attention to whether every word remains easy to hear and whether the soundtrack changes abruptly at a cut.

Give follow-up instructions around the moments that need work:

Lower the music during the setup section. The dialogue needs to be more prominent there. Keep the opening music level as it is.

You can keep refining the mix with the agent or use the manual audio controls to adjust individual levels yourself.

See audio tracks and fades on the timeline.

5. Bring the shots together with colour correction

Moving between recordings can reveal differences in exposure or white balance. Ask the agent to bring those shots closer together before applying a stronger creative look.

For the walkthrough:

Match the presenter shots for brightness and white balance. Keep skin tones natural and leave the screen recordings unchanged.

The last instruction gives the colour work a boundary. Interface recordings serve a different purpose from camera footage, so they may not need the same treatment.

Review adjacent shots together. A correction can look fine on one clip but feel noticeably warmer or brighter when the next shot plays.

If a shot still stands out, identify it in your follow-up instructions. You can also refine the result using the editor’s colour wheels, curves and scopes.

See a colour-correction follow-up and controls.

6. Add movement and transitions with a purpose

Once the structure, visuals and sound are working, consider where movement would help direct attention. Explain that purpose when asking the agent to add it.

For our walkthrough, that might mean a closer view of a small interface detail:

Add a gentle zoom into the settings panel during this explanation. Keep the relevant controls visible and return to the full interface before the next step.

Be specific about the intended effect. “Make it more dynamic” could mean faster cuts, more movement or additional graphics. Explaining what the viewer needs to notice gives the change a clearer purpose.

Use transitions to support the sequence too. A section change may benefit from one; a continuous demonstration may read more clearly with a simple cut.

You can refine movement and timing directly with keyframes when you want more precise control over how an animation starts, moves and settles.

7. Add graphics, captions and animated titles

With the main edit in place, give the agent instructions for the text and graphics that help viewers follow along. For our walkthrough, that could include an opening title, labels for each setup step, and captions for the presenter’s dialogue.

Start with a specific task:

Add an opening title that reads “Setting up your first project.” Keep it simple and readable, with a short entrance animation. Clear it before the setup demonstration begins.

Then build on it:

Add step labels during the setup: “1. Create a project,” “2. Upload your files,” and “3. Build your first sequence.” Position them so they don’t cover the interface controls being demonstrated.

Once those are in place, add captions:

Add captions for the presenter’s dialogue. Use a consistent, readable style and keep them clear of the step labels and important interface details.

Each element should have a job. Titles introduce a section, labels explain a step, and captions make the spoken content easier to follow. Keep animations brief enough that viewers have time to read the text once it settles.

Check caption wording, especially product names and technical terms, and adjust any text that disappears too quickly or competes with the demonstration.

See editable captions in the project.

8. Review the complete edit and make focused revisions

Now watch the video from beginning to end. Turn anything that needs changing into a focused instruction for the agent, or make the adjustment directly on the timeline.

For the walkthrough, check whether a first-time viewer could follow the setup without guessing what happened between steps. Then look at the details: complete sentences, readable screen captures, consistent sound and enough time to absorb each action.

Repeated ideas are worth checking. The agent can remove retakes, but an explanation phrased differently may still repeat a point already made.

Keep your revisions specific:

Remove the second explanation of the setup requirement. Keep the demonstration that follows it.

Or:

Hold the final result on screen for two more seconds so viewers have time to see it. Leave the closing voiceover unchanged.

Work with the agent for the changes you want to delegate, and use manual controls whenever that is the quicker way to get the result you have in mind.

9. Export the finished video

Once you’re happy with the edit, export the finished video from invideo Editor.

If you prefer to finish in Premiere Pro, Final Cut Pro or DaVinci Resolve, you can export an editable project with your timeline and media properly linked, then continue with your usual finishing workflow. See supported export options.

Working this way is useful when you want help carrying out the many tasks between a brief and a finished video. You develop the edit in stages, giving the agent a clear job at each step and building on the result.

AI video editing FAQs

1. Do I need to describe the entire edit in one prompt?

No. Start with the concept, then give detailed instructions for the base cut. Add further direction as you move into supporting visuals, sound, colour and finishing.

2. Do I need a script to edit with AI?

No. You can explain the sequence and outcome you have in mind. If you have a script, include it to give the agent a more specific reference for the assembly.

3. Can I manually change the AI’s edits?

Yes. The clips remain on an editable timeline, so you can trim, rearrange and refine the work yourself. You can move between prompting and manual editing throughout the project.

4. Will the AI remove every repeated take correctly?

It can identify and remove repeated takes, though it may sometimes miss an idea repeated in different words. If that happens, point out the duplication and tell it which version to keep.

5. Can I use my own footage and music?

Yes. Include your recordings and assets in the project, and explain how you want them used. State clearly when you want the edit to use only the material you’ve supplied.

6. How can I learn AI video editing?

Start with a short video and learn one task at a time. Upload your footage, explain the video you want to make, and ask the AI to assemble a first cut. Then practise adding B-roll, balancing music, correcting colour and creating captions. Review each result, give specific follow-up instructions, and use manual controls to refine the edit.
