FLUX 3 First / Last Frame Guide
Create controlled FLUX 3 transitions between a defined start image and end image with coherent motion and preserved visual identity.
How this workflow works
The first/last-frame endpoint defines both ends of the shot. Your prompt should focus on the physical and camera path that makes the transition believable.
FLUX 3 Video
Use compatible endpoints
The more the first and last images agree on identity, lighting and scene geometry, the less corrective invention is required.
Explain intermediate motion
Describe how pose, camera and environmental elements evolve over time. Avoid sudden unmotivated state changes.
Protect high-value details
For products, faces and logos, explicitly state what must remain unchanged throughout the interpolation.
