AI long video to Shorts

Turn long videos into Shorts that stand on their own.

Q: How do I turn a long video into multiple Shorts?

Add the long recording to a Captionate project and ask the AI editor to create distinct Shorts. Review each proposed story, then refine its opening, ending, framing, captions, and pacing.

Q: How does AI decide where each Short should start and end?

Captionate considers the surrounding context so a Short can begin with a useful hook and retain the explanation, reaction, or payoff that completes the idea.

Q: Can I change the hook or edit an individual Short?

Yes. Each result remains editable. You can change its source ranges directly or give the AI editor a follow-up instruction that targets one Short.

Find distinct stories in one recording and shape each one into a focused vertical video with a strong opening, complete context, captions, and an editable cut.

Interactive example

A vertical crop is not the whole edit.

Each result needs its own idea, opening, composition, caption rhythm, and ending. The example below makes those four editorial decisions visible.

01 / 04

Separate the stories

Separate complete ideas before cutting

The editor identifies material that can support its own opening, context, and ending instead of returning arbitrary time ranges.

Build the opening

Rebuild the opening around the hook

A useful line can move forward without spoiling the ending. In this example, the obstacle becomes the first beat while the reveal stays last.

They told me the view was worth the climb.

Compose for vertical

Keep the active subject in frame

Drag the comparison. The crop can follow a speaker, then move to the object or action that becomes important instead of remaining fixed at the center.

Finish the Short

Give each result an editorial finish

Compare the raw crop with a finished draft. Pacing, captions, emphasis, and sound cues support the meaning of the selected material instead of merely decorating it.

The product outcome

One long recording can become several Shorts that work independently.

SourceLong-formThe full recording stays available

ResultsMultipleFocused, vertical, editable drafts

Openings rebuilt: Each result begins with the reason to keep watching.
9:16 framing applied: The crop follows the speaker, subject, and reveal.
Captions shaped to the story: Timing and emphasis change with each Short instead of using one generic template.

One source, separate results

Keep each Short focused without losing the original recording.

The source remains available while each result gets its own opening, context, ending, framing, and caption treatment.

Edit with direction

Change one Short without starting the whole job again.

Ask for multiple drafts, review what was built, then give a follow-up that changes the actual timeline.

Ask for complete ideas. Define how many Shorts you need and what each result should accomplish.
Protect a reveal. Tell the editor what must stay out of the opening.
Keep editing control. Review the changed ranges and adjust the draft yourself.

Short-form decisions

The edit changes with the story.

Good short-form editing is not a fixed crop and a preset pasted onto every clip.

Start with a hook

Move the clearest obstacle, claim, or question to the opening without breaking context.

Protect the payoff

Keep a reveal out of the first frames when the anticipation is what makes it work.

Frame what matters

Move the vertical crop between the speaker and the detail the viewer needs to see.

Set caption rhythm

Break speech into readable beats and emphasize only the words carrying the point.

Match the pacing

Let the content determine the cut density, emphasis, and breathing room instead of repeating one edit pattern.

AI video to Shorts workflow

Turn a long video into Shorts, not disconnected clips.

Create multiple Shorts from one video

A long recording may contain several useful stories. Captionate can separate those ideas into individual drafts, so a reaction, explanation, discovery, or payoff does not have to share one generic highlight reel.

Give every Short a clear beginning and ending

A useful start time is not always the start of the original scene. Rebuild the opening around the detail that earns attention, retain the context needed to understand it, and let the result reach a conclusion.

Convert horizontal footage for vertical viewing

Reframing a 16:9 source means more than cutting away the sides. The vertical composition can follow the person speaking, move to an object during a demonstration, and make room for readable captions.

Refine the result instead of accepting a locked export

Each Short stays in an editable project. Change source ranges, rewrite or restyle captions, adjust framing, or ask for a different hook without rebuilding every other result.

How it works

From a long recording to editable Shorts in three steps.

Add the long video
Start with the recording you want to repurpose, such as a vlog, stream, podcast, interview, or event video.
Describe the Shorts you need
Ask for distinct stories and add direction about hooks, context, pacing, reveals, or the intended audience.
Review, style, and export
Inspect each vertical draft, adjust its edit and captions, then render the finished results when they are ready.
