How to turn a long video into YouTube Shorts

To turn a long video into a Short, pick one complete idea, cut it to a self-contained moment, crop it to vertical 9:16, add accurate captions, then upload it to YouTube. Do this by hand in an editor, or let a tool like Fresta handle the steps.

The five steps

1. Pick one complete idea. Choose a moment that makes sense without the rest of the video. Keep the setup, because a payoff means little if viewers miss why it matters.
2. Choose the audio. Keep the original speech if the delivery carries the moment. Write a narrated recap if the footage needs explaining, and check every claim against the source.
3. Crop to vertical. Export at 1080 by 1920. Watch the whole clip, because a crop that works in the first frame can lose the action later.
4. Check the captions. Correct names and specialist terms, and keep captions clear of faces and on-screen detail.
5. Title and schedule it. Describe what actually happens in the clip, then watch the final export once more before it goes out.

Doing it by hand or with Fresta

A manual edit gives you frame-level control, which suits montages and complex effects. Fresta suits repeat work: it handles the script, neural voice, word-by-word captions and music, then schedules the finished Short to your YouTube channel.
