Tips for Better Videos

Hook (first 3 seconds): Open with movement, a bold statement, or a visual pattern interrupt

Thumbnail: Use high contrast, large text, and expressive faces for maximum CTR

Visual Pacing: Cut every 2-5 seconds for short-form; use B-roll to maintain interest in long-form

Text Overlays: Highlight key points with on-screen text for viewers watching without sound

Lighting & Composition: Natural light or ring lights work best; rule of thirds for framing
