Image-to-Video and Frame Control
- →Treat the reference still as the dominant input to an image-to-video shot, and prep it accordingly
- →Use last_frame_uri to direct a shot by its endpoints, and explain why it is a genuine reason to be on LTX-2.3
- →Design a start and end frame whose difference implies exactly one motion, and diagnose pairs that will morph instead
- →Use duration as a speed control on a fixed frame pair, and price the comparison
In image-to-video, the dominant variable is not the prompt. It is the frame you hand over.
Everything the shot inherits — the grade, the lens character, the noise floor, the shape of the light, the wardrobe, the set dressing — comes from that still. You are not describing a look. You are supplying one. Which is why this endpoint is usually the right one for professional work: it is the only place where you get to make the most important decision in a paint package, at your own pace, with your own eyes.
