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	Reference-to-Video
Input	1 image (starting frame)	Multiple images (1-5 references)
Purpose	Animate that exact image	Maintain subject consistency in new scenes
The image becomes...	The first frame of the video	A "template" for what subject looks like
Camera/scene	Starts from that exact view	Can be completely different scenes

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
