> TL;DR: Record one strong long video, then cut it three ways: the full edit in 16:9 for YouTube, two to five standalone 20 to 60 second moments reframed to 9:16 for Reels, Shorts and TikTok, and a square or landscape cut for LinkedIn and X. Recaption each version and write a separate post caption per network.

Repurposing is less about exporting the same file in four sizes and more about finding the parts of one recording that stand on their own. A 10-minute talk can hold several good shorts, but only if each one makes sense to someone who never saw the rest. Here is how to pick those moments, reshape them for each platform, write the posts and get each version out, in any editor and in Viditor.

## What is the best way to repurpose one video?

Start from the longest, most complete version and cut down, never the other way round. Edit the full video first, then pull standalone moments out of it for vertical platforms, then write a different post caption for each network. Each version gets its own shape, captions and copy, but the recording only happens once.

| Version | Where it goes | Shape | Length to aim for |
|---|---|---|---|
| Full edit | YouTube | 16:9 | As long as the content needs |
| Standalone moments | Reels, Shorts, TikTok | 9:16 | 20 to 60 seconds each |
| Short landscape or square cut | LinkedIn, X | 16:9 or 1:1 | Under 2 minutes |
| Quotes and key lines | Text posts on LinkedIn and X | Text | A few sentences |

YouTube treats any square or vertical upload of up to three minutes as a Short ([YouTube Help](https://support.google.com/youtube/answer/15424877)), so keep the full edit in 16:9 if you want it treated as a regular video.

## How do I find clips worth repurposing?

Look for moments that make one point, open on a line that works without context and pay off before they end. Read the transcript rather than scrubbing the video. Strong candidates often start with a claim, a number, a mistake or a question, and end on the answer.

Skip moments that point at things the viewer can't see ("as you saw earlier", "this chart here") unless you can bring the visual along. Skip moments where the payoff comes after a long setup. Mark the first and last words of each candidate so you can find them again.

## How do I turn a landscape video into vertical?

Reframe on the speaker instead of centre-cropping. A 9:16 crop of a 16:9 frame keeps roughly a third of the width, so anyone off-centre gets cut. Move the crop to keep the face in frame, and add a punch-in on key lines if the shot feels wide.

1. Duplicate the timeline or project and change the canvas to 9:16 (1080 × 1920).
2. Scale the footage to fill the height and move it so the face sits in the upper middle.
3. Rebuild any on-screen text for the narrow frame. Titles from the wide version usually overflow.
4. Recaption for vertical: shorter lines, larger type, placed above the bottom interface. Check placement with the [safe zone checker](https://viditor.app/tools/safe-zone-checker).
5. Trim the opening so the first line is the hook, not a greeting.

## What should change between platforms besides the shape?

The caption text, the title and the opening second change most. The same clip can work on Reels and LinkedIn, but the post around it shouldn't be identical.

- **YouTube:** a searchable title, a description with chapters for long videos, and a designed thumbnail.
- **Reels, Shorts, TikTok:** a first line that works with the sound off, burned-in captions, and text kept clear of the side buttons.
- **LinkedIn:** a caption that states the point in the first two lines, before the "see more" cut. LinkedIn accepts aspect ratios from 1:2.4 to 2.4:1 and videos up to 15 minutes ([LinkedIn Help](https://www.linkedin.com/help/linkedin/answer/a548372)).
- **X:** a short post with the hook as text. X's developer docs recommend 16:9 or 1:1 ([X docs](https://docs.x.com/x-api/media/quickstart/best-practices)).

## How do I repurpose a video in Viditor?

Ask the assistant to find the shorts, choose one, and it builds that cut; it lists the others with their source ranges so you can cut them next. Reframing, recaptioning and post captions happen in the same chat.

1. **Edit the long version first** and export it in 16:9. An export is a finished MP4 on your Mac, so changing the project afterwards doesn't touch the file you exported.
2. **Ask for clips:** "find the best three to five shorts in this". The assistant splits the transcript into ranges, scores them in parallel, and ranks standalone moments of 20 to 60 seconds by hook strength, then payoff. You get the top three to six with times and opening lines to choose from.
3. **Build the chosen one.** It removes everything outside the moment, keeps natural breaths, tightens the open, switches the project to 9:16 and reframes on the measured face.
4. **Keep the list.** The assistant's reply gives each other moment a title, the hook line and its exact source range. Copy it somewhere you'll find it, and cut each one in its own project later.
5. **Check the frame.** The assistant reviews composed frames, not just the transcript, and flags captions over faces or under the Reels, TikTok and Shorts interface.
6. **Write the posts.** Ask "write the post captions for Instagram, LinkedIn and X" and the assistant replies with one version per network, written from what the edit actually says. Copy them; nothing is saved or sent.

Viditor projects come in three shapes: 16:9 (1920 × 1080), 9:16 (1080 × 1920) and 1:1 (1080 × 1080). There is no 4:5 option, so a 4:5 feed post needs the square version or a crop elsewhere.

## How do I post or schedule each version?

Export each version as its own file, then upload it where it goes: Instagram, TikTok or YouTube Shorts for the vertical cuts, YouTube Studio for the full edit, LinkedIn or X for the square or landscape cut. Use the platform's own app or whatever scheduling tool you already use, and paste the caption you wrote for that network.

In Viditor, every export is listed in the **Exports** tab on the home view, newest first. Play one to check it, or click **Show in Finder** to grab the file. Viditor doesn't post or schedule anything, and your finished videos stay on your Mac until you upload them yourself. Ask for an export review and it listens to the finished file, checking loudness against the -14 LUFS target, peaks, black or frozen frames and long silences, so you upload a file that's already been checked. The [export docs](https://viditor.app/docs/export) cover the details.

A few habits make posting a week of pieces easier, whichever tool you post with:

- **Name files by platform and hook**, for example "launch-short-02-reels.mp4", so you never upload the 16:9 version to Reels.
- **Keep the caption next to the file.** Paste each network's caption into a note with the file name, so posting is copy, upload, paste.
- **Space the shorts out.** Post the full edit first, then one short every day or two, so each one gets its own moment in the feed.

## How do I keep captions right across every version?

Recaption each version rather than reusing the long video's caption file. Line length, size and position depend on the frame: a two-line caption that fits a 16:9 frame wraps into four lines in 9:16 and covers the face. Generate captions after the cut is final, then check the first and last line of each clip.

If you publish the long version on YouTube with closed captions, keep an SRT for it. For shorts, burn the captions in so the clip still works with the sound off. The difference is covered in [burned-in vs closed captions](https://viditor.app/blog/burned-in-vs-closed-captions). In Viditor, captions are anchored to the spoken words, so when the assistant trims a clip out of the long edit, the captions follow the words that stay instead of drifting.

## How many pieces can one video realistically become?

As many as it has standalone moments, and no more. A focused 10-minute video with a clear argument might give you several good shorts. A meandering one might give you one. Forcing weak clips out to hit a number trains your audience to scroll past you.

A practical target for one long video: the full edit, two to five shorts, one LinkedIn cut and a couple of text posts built from the best lines. If you film every week, the pieces from one recording fill most of a posting week, and [batching](https://viditor.app/blog/batch-a-week-of-short-form-content) covers the rest.

## Honest limits

- Viditor projects export in 16:9, 9:16 or 1:1 only, at 1080p/30.
- One project holds one timeline, so each short is cut in its own project.
- Timelines max out at 5 minutes, and a project takes up to 30 minutes of imported footage.

## Frequently asked questions

### What makes a good clip to repurpose from a long video?

A moment that makes one point, opens on a line that works without context, and pays off before it ends. If it needs the previous two minutes to make sense, it won't work as a short.

### Can I just crop a landscape video to vertical?

Only if the subject stays in the middle third of the frame. A centre crop of a 16:9 frame keeps about a third of its width, so reframe on the speaker's face and check any on-screen text, which usually gets cut off.

### Can Viditor find the best clips in a long video?

Yes. Ask it to find shorts and it scores the transcript in parallel, ranks standalone moments by hook and payoff, and shows you the top three to six with times and opening lines. It builds the one you choose and lists the others in its reply with titles, hook lines and exact source ranges, so you can cut each in its own project.

### Can Viditor post or schedule the versions for me?

No. Viditor edits and exports MP4s on your Mac, and every export is listed in the Exports tab. You upload each version yourself in the platform's app or the scheduler you already use. The assistant can write the post captions in chat for you to paste.

### Does Viditor export 4:5?

No. Viditor projects are 16:9, 9:16 or 1:1, at 1080p and 30 fps. For a 4:5 feed post, use the 1:1 or 9:16 version, or crop in another tool.
