Why Text to Video AI Works on YouTube Shorts

YouTube Shorts prioritizes:

• Average view duration
• Rewatches
• Engagement signals (likes, comments, subs)

• Produce content at scale
• Test multiple hooks quickly
• Stay consistent without burnout
• Focus on ideas instead of editing

In Shorts, ideas and hooks matter more than visuals.

What Makes a High‑Retention YouTube Short?

1. A Hook in the First 1–2 Seconds

Your opening line determines whether viewers stay or swipe.

2. Vertical Format (9:16)

Shorts must feel native to mobile.

3. Clear On‑Screen Text

Many viewers watch without sound.

4. Simple Visual Flow

Avoid complex scene changes that distract from the message.
