Question 4

Can Ray2 720p use an image as input?

Accepted Answer

Yes, Ray2 720p supports image-anchored generation. Creators can provide optional start and/or end frames to guide visual continuity throughout the generated video. This feature helps maintain consistent visual style and subject appearance across the clip.

Question 5

What aspect ratios does Ray2 720p support?

Accepted Answer

Ray2 720p supports multiple aspect ratios ranging from vertical 9:16 for mobile and social platforms to ultra-wide 21:9 for cinematic or widescreen delivery. This flexibility makes it suitable for platform-specific content creation across social media, presentations, and installations.

Question 6

What makes Ray2 720p different from other AI video models?

Accepted Answer

Ray2 720p stands out with 10x the compute scale of its predecessor, 35+ named camera controls, physics-based simulations for liquids and atmospheric effects, and photorealistic rendering. It also supports seamless looping output and both text-to-video and image-anchored generation modes.

Question 7

How do I access Ray2 720p on Craisee?

Accepted Answer

Ray2 720p is available on Craisee via the Replicate provider under the model ID luma/ray-2-720p. It is categorized under Text-to-Video and is the recommended model for creators needing professional-grade 720p video output with precise camera and physics control.

Question 8
