Flux 3 Start-End to Video: animate between two frames with precision
A tradução deste card ainda não está disponível; parte do conteúdo aparece em inglês.
Flux 3 Start-End to Video is part of the Flux model family and focuses on a specific creative task: generating video that connects two user-provided frames. You supply a starting image and an ending image, and the model produces a short video that smoothly transitions between them, filling in the intermediate motion.
This makes the model especially useful when you already know exactly how a clip should begin and end — such as a character pose, a product angle, or a scene composition — and want believable movement in between. Compared to text-only video generation, start-and-end conditioning gives users far more directorial control over the final result.
Flux 3 Start-End to Video stands out for its strong adherence to both endpoint frames, natural-looking interpolation, and clean handling of subjects like people, objects, and environments. It's a great choice when consistency between two reference points matters more than open exploration.
- Animating a character from one pose to another
- Product rotation between two camera angles
- Cinematic scene-to-scene transitions
- Before-and-after reveal sequences
- Social media motion clips from still photos
Stays faithful to both the supplied start and end images without drifting.
Produces smooth, believable transitions rather than abrupt jumps.
Works well with people, products, environments, and stylized artwork.
- Choose start and end frames with similar lighting and perspective for smoother results.
- Keep the subject placement consistent across both images to avoid sudden shifts.
- Use high-resolution, clear images so the model can track details accurately.
- Experiment with subtle pose or camera changes for the most natural motion.
- Short clip duration only — not suitable for long-form video.
- Motion is constrained to what fits between the two endpoint frames.
- Complex multi-character scenes may show minor inconsistencies in detail.
Start: skateboarder mid-air above a ramp. End: skateboarder landing cleanly on the ramp, dynamic angle.
Start: closed flower bud in a glass vase. End: same flower fully bloomed, soft focus background.
Start: quiet city street at dawn, muted colors. End: same street at night with glowing neon signs.
Frames per second, controlling how smooth the motion appears.
A number that locks the randomness so you can reproduce the same result later.
The amount of computation used to generate each frame; more steps can mean smoother results.
How long the output video should be, usually measured in seconds.
The final frame the video should reach.
The first frame the video begins from.
The width-to-height shape of the generated video, such as 16:9 or 9:16.
How strongly the model should follow the start and end images versus adding its own interpretation.

What inputs does Flux 3 Start-End to Video need?
It requires a starting image and an ending image that define the two endpoints of the animation.
How long are the generated videos?
Clips are short, designed for brief transitions, social posts, and looping animations.
Can I use it for full scenes from scratch?
It's best when you already have the beginning and end frames; for purely text-driven video, a different model is more suitable.
