Understanding YouTube Shorts in 2025

Before diving into the repurposing process, it’s important to understand what makes YouTube Shorts unique and why they’re worth your attention. YouTube Shorts are vertical videos catered primarily to mobile users with specific technical requirements:

  • Duration: Up to 60 seconds (with 15-30 seconds considered the optimal length for engagement)
  • Aspect ratio: 9:16 vertical format
  • Resolution: 1920 x 1080 pixels
  • File format: MP4 or MOV
  • Codec: H.264
  • Frame rate: 24-60 fps
  • Bit rate: 1-6 Mbps
  • Audio format: AAC or MP3

The platform continues to prioritize Shorts in its algorithm, giving creators who utilize this format increased visibility. In 2025, YouTube has enhanced its Shorts monetization program, offering creators a share of ad revenue from the Shorts feed. To qualify for monetization, you need at least 500 subscribers, three public uploads in the last 90 days, and either 3,000 watch hours or 10 million valid public Shorts views in the past 90 days.

Step 4: Using AI to Extract High-Value Clips

This is where the magic of AI-powered video clipping happens. Each tool works slightly differently, but the general process involves:

  • Upload or link to your long-form YouTube video
  • Allow the AI to analyze the content (this may take several minutes)
  • Review the AI-suggested clips (most tools will identify emotional peaks, key phrases, or visual interest points)
  • Select the clips that best serve your Shorts strategy
  • Make minor adjustments to clip boundaries if needed

The best AI tools for YouTube content repurposing will identify not just any random segments, but moments that have natural beginnings and endings, emotional impact, or complete thoughts that stand alone.

Step 5: Optimizing Shorts for the 9:16 Format

Once you’ve extracted your clips, it’s time to transform long-form video into bite-sized content by optimizing for the vertical format:

  • Reframe the composition: Use AI tools to automatically center the most important visual elements
  • Apply the 9:16 aspect ratio: Most AI tools will automatically convert your horizontal video to the vertical Shorts format
  • Add padding if necessary: Some tools add blurred backgrounds to fill empty space around horizontal footage
  • Adjust text positioning: Ensure any on-screen text is visible in the vertical format
  • Optimize for mobile viewing: Test your video on a smartphone before publishing

Advanced AI tools for YouTube Shorts creation using AI can intelligently track subjects and keep them centered even as they move throughout the frame, making the vertical adaptation look natural rather than cropped.

Step 6: Enhancing Shorts with AI-Powered Features

To make your repurposed Shorts stand out, leverage these AI enhancement capabilities:

  • Automatic captions: AI can generate and synchronize captions for better accessibility and engagement
  • Voice-to-text optimization: Some tools clean up speech automatically for clearer communication
  • Background removal: Isolate subjects against new backgrounds for visual variety
  • Music recommendation: AI can suggest trending background tracks that match your content’s mood
  • Highlight detection: Emphasize key moments with automatic zoom or visual effects
  • Tempo adjustment: Speed up or slow down segments to fit the Shorts format better
  • Auto transitions: Create smooth flow between different clips

Step 7: Adding Shorts-Specific Elements

When using AI tools for YouTube Shorts, you can set parameters to extract clips within this ideal duration range.

Can I monetize repurposed YouTube Shorts in 2025?

Yes, YouTube offers monetization for Shorts creators meeting specific requirements: 500 subscribers, three public uploads in the last 90 days, and either 3,000 watch hours or 10 million valid public Shorts views in the past 90 days. Repurposed content is eligible as long as it meets YouTube’s content guidelines.
