Luma Ray 3.2

Ray 3.2 supports text-to-video and image-guided generation through one keyframe workflow. Choose resolution, duration, and aspect ratio, place up to 64 anchors on the exact 24 fps grid, optionally enable HDR for compatible 5-second output, or request a seamless SDR text-only loop.

How to use this model

  1. 1

    Describe subject motion, camera movement, lighting, and pacing in the prompt.

  2. 2

    Add keyframes when the shot must follow supplied imagery, then position each anchor independently on the timeline.

  3. 3

    Move any keyframe on the timeline; every timestamp snaps to an exact 24 fps frame.

  4. 4

    Enable HDR only for 5-second 720p or 1080p output; it preserves the provider's HDR MP4 and costs more than SDR.

  5. 5

    Enable looping only for 5-second SDR generation without keyframes.
