Agentic Extend:
Your Footage Ends, Your Scene Doesn't Have To

Need a longer ending, a lead-in, or a line of dialogue that finishes? Ask the agent in invideo Editor to generate it right on your timeline, up to 30 seconds at a time.

Open timeline→Attach clip→Plan→Generate→Review→Refine

Part 1 · What you can extend

Agentic Extend lets you generate the missing part of a shot at the beginning, at the end, or in a gap in the middle, by up to 30 seconds of new footage for each extension.

The end of a shot

Let a moment breathe, hold on a reaction, or let the action finish.

The start of a shot

Add a few seconds of lead-in before the action begins.

A gap in the middle

Fill a hole between two clips with a new take that joins both sides.

Dialogue

Let a line finish, or add a short new line to a shot.

Part 2 · Step by step

  1. 1

    Open your timeline

    Open your project in the Edit workspace and open the timeline that holds your clip. Find the clip you want to extend, then play it in the Monitor and decide what's missing: a lead-in, a longer ending, or footage to fill a gap.

    Attach your clip and tell the agent what to extend

    Open the agent panel with the agent button in the top left corner of the Editor. Add the clip you want to extend to the chat, then tell the agent where (before, after, or in a gap), how long (up to 30 seconds), and to put the result on your timeline.

    Variation 1: extend before the clip starts

    "Extend this clip by 10 seconds before the clip starts and put it in my timeline."
    Variation 1"Extend this clip by 10 seconds before the clip starts and put it in my timeline."

    Variation 2: extend after the clip ends

    "Extend this clip by 15 seconds after the clip ends."
    Variation 2"Extend this clip by 15 seconds after the clip ends."

    Variation 3: extend both ends

    "Extend this clip by 30 seconds before and after."
    Variation 3"Extend this clip by 30 seconds before and after."

    Let the agent analyze and plan

    Once you send your request, the agent works out a plan and tells you what it's doing in plain language:

    • 1. Plans the jobs. It splits the work into separate jobs, one per extension, each matched to its own clip, and brings the clips into the project first.
    • 2. Generates the new footage. It creates each extension and keeps your originals intact, joining each one to its new footage on the timeline.
    • 3. Reports progress and checks your edit. It tells you when each extension is done and checks what's already on your timeline so it builds on your edit instead of over it.
    • 4. Explains the result. For example, a clean 10 second lead-in with its last frame landing exactly on your clip's first frame. It also flags caveats, like new footage rendering at a lower resolution, and offers to upscale it.
    The agent's replies: the plan, generating, progress, and the finished lead-in with a resolution caveat.

    The agent generates, checks, then edits

    The agent doesn't just drop the first result into your edit. It leaves your timeline as it is until it has checked that the framing, lighting and action match your clip, and that the join lands cleanly. If a take doesn't match, it can generate another one before anything goes onto your timeline.

  5. 5

    Review the result on your timeline

    The new footage sits on your timeline like any other clip. Play through it in the Monitor and check that the action, motion and sound carry smoothly into your original clip. If the agent flagged a lower resolution, ask it to upscale before you export.

  6. 6

    Refine with follow-ups

    Keep the conversation going until it's right. The agent may ask whether to add new sound effects or keep only the existing audio. You can also ask for a different take, a shorter or longer extension, different action, or different audio.

Part 3 · Prompt ideas to try

Adapt these to your own footage.

Extend the end (with direction)

"Extend the end of this shot by 5 seconds. He finishes writing, leans back in his chair and looks at the screen."

Extend the start

"Extend this clip by 10 seconds before the clip starts and put it in my timeline."

Extend both ends

"Extend this clip by 30 seconds before and after."

Fill a gap

"Fill the gap in the middle with a new take that matches the framing and lighting on both sides."

Finish the dialogue

"The line gets cut off. Extend the shot so the sentence finishes, then hold for a beat."

Tips for better extensions

  • Point to the exact spot. Name the clip, the gap, or what happens right before and after.
  • Describe the action, not just the length. "He walks in, sits down and starts writing" works better than "add 10 seconds".
  • Clean up the edges first. Stray frames at a cut can throw off the join. The agent may catch them, but check.
  • Say what to leave alone. For example: "keep the existing audio" or "don't add new sound effects".
  • Always watch the joins. The agent checks its work, but AI agents can make mistakes, so review the cut before you export.
  • Stay within 30 seconds. Per extension. For longer additions, extend in stages.
