FAL Model Selector

Quick decision guide for choosing fal.ai models. Read references/ for full parameters.

Key Concepts

Image-to-Video vs Reference-to-Video

Image-to-Video = "animate this exact image"

• Product photo → animate it rotating
• Portrait → make the person smile/blink

Reference-to-Video = "generate video featuring this subject"

• 3 photos of mascot → video of mascot in new scene
• Product from different angles → consistent commercial
