How to turn long videos into TikToks, Reels and Shorts
Last updated 17 July 2026
Turning a long video into shorts means cutting a recording down to its strongest moment, formatting it vertical, and captioning it so it holds attention. With YouClip you import the full recording, it finds and trims the clip worth posting, adds word-synced captions, and exports at 1080x1920 ready for TikTok, Reels and Shorts.
Step by step
Import the long recording
Open YouClip and add the full video: a podcast, stream, webinar, or a long talking-head take. You don't need to pre-trim it.
Let YouClip find the moment worth posting
YouClip cuts the recording down to the segment most likely to work as a short, so you skip scrubbing a timeline looking for the good bit.
Add captions
The clip is transcribed and captioned automatically, with each word lighting up as it's spoken. Pick the font and highlight colour that match your channel.
Frame it vertical
Set the caption size and position for a 9:16 frame and check the text sits clear of the platform's on-screen buttons.
Export and upload
Render at 1080x1920 and upload the file directly to TikTok, Reels or Shorts. The same export works on all three.
Why repurpose long video into shorts?
One long recording is a week of short-form content waiting to happen. A single podcast, stream or webinar usually holds several standalone moments that each work as a clip. Repurposing them is the fastest way to stay consistent on TikTok, Reels and Shorts without filming something new every day, and captioned vertical clips are exactly what those feeds reward.
What makes a clip work
- One idea: a clip should make a single point, land a single laugh, or answer a single question.
- A strong first second: lead with the hook, not the setup, so viewers stop scrolling.
- Captions on by default: assume the sound is off, because for most viewers it is.
- Vertical framing: fill the 9:16 frame and keep captions clear of the platform's buttons.
Turn one recording into many
Instead of posting a long video once, pull three or four moments out of it and schedule them across the week. Save your caption font, colour and position as a preset so every clip looks like it came from the same channel, and you have a repeatable system rather than a one-off edit. When you have several clips lined up, you can caption the whole folder at once instead of editing them one by one.

Frequently asked questions
What length should a TikTok, Reel or Short be?
Most short-form clips land between 15 and 60 seconds. Cut to the single strongest moment rather than stretching to fill time; a tight 20-second clip usually outperforms a loose 60-second one.
Do I have to find the best moment myself?
No. YouClip trims the long recording down to the segment worth posting for you, so you don't have to watch the whole thing back and drag clips around a timeline.
What size do TikTok, Reels and Shorts use?
All three are vertical 9:16. YouClip exports 1080x1920, so one render is ready to upload to every platform without resizing.
Can I make several clips from one recording?
Yes. Run the recording through YouClip for each moment you want to post, so a single long video can become a week of shorts.
Do I need editing experience?
No. YouClip handles the cut, the transcription and the captions, so you only choose the style and hit render. There's no timeline to learn.
