Flux 3 First Last Frame to Video is a specialized video model that takes two images—a first frame and a last frame—and generates the in-between motion to create a seamless short video. It is ideal for creators, educators, and marketers who need quick animated transitions or visual stories without frame-by-frame editing.
Use this model when you have a clear beginning and end in mind and want the model to fill in the motion. It works well for product reveals, scene transitions, simple character movements, and illustrative storytelling where the endpoints are already defined.
What makes Flux 3 distinctive is its focus on coherence between two fixed points. Rather than generating video from text alone, it respects the visual content of both input frames and produces motion that feels intentional and grounded in the provided imagery.
- Animating product reveal transitions
- Creating scene-to-scene storyboards
- Generating character entrance and exit clips
- Building simple educational motion graphics
- Designing social media transition effects
The generated video stays visually consistent with both input frames.
Produces short clips quickly, ideal for rapid iteration.
Only requires two images to create a complete video sequence.
- Keep the first and last frames visually related for smoother results.
- Use high-resolution input images for clearer output video.
- Avoid drastic lighting or perspective changes between frames.
- Set a fixed seed if you want to reproduce a specific result.
- Limited to short video durations (typically a few seconds).
- Motion quality depends heavily on how similar the two input frames are.
- Fine details or fast motion may appear blurry or inconsistent.
First frame: a bright city skyline during the day. Last frame: the same skyline at night with lights on. Generate a cinematic day-to-night transition.
First frame: scattered product parts on a table. Last frame: the fully assembled product. Generate a short clip showing the parts coming together.
First frame: a closed flower bud. Last frame: a fully bloomed flower. Generate a gentle time-lapse-style blooming animation.
A number that makes results reproducible if you want to generate the same video again.
Number of processing steps used during generation; more steps can improve quality but take longer.
Limits which motion patterns are considered; lower values focus on the most likely transitions.
Controls how long the generated video clip is, in seconds.
Controls randomness in motion; lower values produce more predictable results.
Sets the width-to-height ratio of the output video, matching your input frames.
Determines how closely the video follows the input frames; higher values mean stronger adherence.

What inputs does Flux 3 require?
It requires two images: a first frame and a last frame to interpolate between.
How long is the generated video?
The output is a short clip, typically a few seconds long.
Can I control the motion style?
Motion is largely determined by the input frames, though parameters like duration and guidance can influence the result.
