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 losing the explanation around it. Here, the counterintuitive conclusion becomes the opening, then the question restores its context.

Compose for vertical
Keep the active subject in frame
Watch the 9:16 frame follow the active speaker and settle naturally as the subject changes position.
04 / 04
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.

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.
FAQ
Long video to Shorts questions.
How do I turn a long video into multiple Shorts?
Add the 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.
How does AI decide where each Short should start and end?
Captionate considers surrounding context so a Short can begin with a useful hook and retain the explanation, reaction, or payoff that completes the idea.
Can I change the hook or edit an individual Short?
Yes. Each result remains editable. Change its source ranges directly or give the AI editor a follow-up instruction that targets one Short.
Can Captionate reframe horizontal video for vertical platforms?
Captionate can compose a vertical draft from horizontal footage and move the crop to keep the speaker, subject, or important detail in frame. You can review and adjust the result.
Are captions included in the generated Short drafts?
Yes. Caption timing and treatment can be included in a Short draft, while the caption track and style remain editable before export.
