Luma Ray Flash 2 Reframe
Luma Ray Flash 2 Reframe is a Luma route built for visual reframing. It turns an existing visual asset and target canvas into a recomposed result for a different aspect ratio, giving creators a focused endpoint instead of forcing one generic workflow across materially different production tasks. The route belongs to a family known for natural motion, strong prompt interpretation, and cinematic camera behavior, so it is best evaluated as a creative system for intentional shots and assets rather than as a one-click novelty generator.
Use this endpoint when the input contract and deliverable match that job exactly. Its documented controls include aspect_ratio choices (21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16). Together, these controls help teams plan predictable iterations, compare outputs under stable settings, and connect generation to concept films, campaign visuals, and rapid shot exploration without hiding the operational choices that shape the result.
Highlights
- Luma Ray Flash 2 Reframe: dedicated canvas reframing. This exact route centers on canvas reframing; it uses
prompt,imageto separate its job from neighboring endpoints in the same family. imagecontrol. Optional URL of the first frame image for reframing; this setting provides a concrete lever for route-specific output planning.videocontrol. URL of the input video to reframe; use it to build controlled comparisons without changing the rest of the request.aspect_ratiocontrol. options21:9,16:9,3:2,4:3,5:4,1:1,4:5,3:4,2:3,9:16; together with the other documented fields, it supports repeatable review of this model path.

When to Use
| Scenario | Why this model fits |
|---|---|
| Create the exact route output | Choose it when you need visual reframing and already have an existing visual asset and target canvas. |
| Develop controlled variations | Keep the main brief fixed while changing one documented setting at a time to compare motion, framing, quality, or asset behavior. |
| Build repeatable batches | Use a consistent request shape for catalog, campaign, storyboard, game-asset, or social-content production. |
| Preserve source intent | Prefer this route when the supplied reference material must remain the foundation of a recomposed result for a different aspect ratio. |
| Connect a media pipeline | Use asynchronous results in an automated review, approval, post-production, or asset-management workflow. |
Prompt Guide
Start with the desired result, then describe the source relationship, subject action, composition or camera behavior, lighting, style, and timing. For visual reframing, state what must remain stable as clearly as what should change. Use only fields exposed by the schema; the example below is structurally valid for this route.
{
"prompt": "A cinematic product shot with deliberate camera movement, natural light, and clearly described timing.",
"image": "https://example.com/reference.jpg",
"video": "https://static.sandbase.ai/examples/luma/ray-flash-2/reframe/output_url_0.mp4",
"aspect_ratio": "21:9"
