How to Turn a YouTube Video Into Shorts

To turn a YouTube video into Shorts, select strong moments, trim to under 60 seconds, reformat vertically, and add captions for engagement.

1. Identify the Best Moments

Start by watching your YouTube video and noting standout moments that work as self-contained clips. Look for jokes, tips, reactions, or story beats that can grab attention quickly. These are ideal for Shorts and other vertical platforms.

2. Trim to Under 60 Seconds

YouTube Shorts must be 60 seconds or less. Cut your selected segment so it’s concise and impactful. Remove pauses, filler, or anything that doesn’t support the main message of the clip.

3. Reframe to 9:16 Vertical Format

Shorts are viewed vertically on mobile, so reformat your clip to a 9:16 aspect ratio. Most editing apps let you crop or reposition footage. Focus on the subject or action to keep it centered and clear.

4. Add Captions and a Strong Hook

Start with an eye-catching first second - a question, reaction, or bold statement helps.
Add large, readable captions to improve engagement and accessibility. Highlight key words or phrases.

5. Use AI Tools to Speed Up the Process

Apps like Vidulk can automatically find highlight moments, trim them to Shorts length, and reformat for vertical video. Simply upload your YouTube link, let the AI generate suggested clips, and make final edits as needed. Vidulk is free to start, with paid options for higher volume or advanced processing.

Skip the manual editing - Vidulk's AI finds and cuts the best moments into ready-to-post clips. Free to start.
