First-frame motion
Give the still model one clear path
The frame owns train, rails, carriage count and handmade material; the prompt adds departure, travel and tracking.
Kling V1.5
Turn an established visual direction into a controlled short clip with one or two boundary images.
Start and end frames
Decide whether the constraint sits at the start, end or both
Kling V1.5 does not expose text-to-video in Flux Art. First frame describes what follows, last frame works backward to the arrival, and boundary frames fill motion between two known states.
Image-to-video onlyStandard and Pro first framePro last framePro boundary framesAdherence control
Last-frame arrival
Work backward from the finish
The last frame fixes runner, arch and pose; the prompt explains approach, crossing, slowdown and raised arms.
Boundary-frame path
Solve only the motion between known ends
Boat folds and channel stay fixed while the prompt owns current, rotation, tracking and stop.
Boundary inputs
Decide which input owns the information
The input route defines existing visual facts. The prompt should supply motion and change instead of competing with the source.
First frame
Describe motion after the image in Standard or Pro.
Pro last frame
Work backward from a target ending.
Pro start and end
Generate the transition between two known states.
Transition control
Where Kling V1.5 fits
Use it when a reliable still needs foundational single-subject motion, a simple camera move or a clearly defined arrival state.
Motion after a first frame
The image owns person, composition, material and light while the prompt describes subsequent action and camera.
Arrival at a last frame
Work backward from the target ending, explaining how subject and camera enter it and align at the finish.
Boundary-frame path
Boundary images fix the states while the prompt owns path, speed, force and continuity.
Adherence and exclusions
Use adherence to control prompt strength and negative prompts to exclude new people, structural change or style drift.
Path scripts
Kling V1.5 image-to-video briefs
Each brief solves one boundary relationship so image and text do not compete.
Miniature train departure
The first frame owns green toy train, alpine miniature and warm light. Wheels begin slowly; train moves front-right and chimney releases a little white steam by the cabin. Camera tracks at model height. Preserve carriage count, rails, building scale and handmade material.
Forest finish arrival
The last frame owns runner under red arch, raised arms and morning mist. Begin farther behind as he runs steadily, crosses, slows and raises arms; camera pushes slightly and arrives exactly at the frame. Preserve one runner, arch shape and mist light.
Paper-boat boundary path
The first frame places the paper boat at channel start; the last has it before the bright drain. Water carries it along the curved stone path, it rotates slightly around one leaf and continues; low tracking stops at the final frame. Preserve folds, orientation, channel and wet reflection.

How to use Kling V1.5 in Flux Art
Public official capability detail for Kling 1.5 is limited; Kuaishou's 2025 material records Kling 1.5 Pro among leading third-party image-to-video rankings. To avoid extrapolation, this page follows current Flux Art configuration: first frame supports Standard and Pro, last and boundary frames are Pro only, with adherence and negative prompts.
Create with Kling V1.5- Choose boundary positionUse first frame, Pro last frame or Pro boundary frames; add a second image only when the ending truly matters.
- Write missing temporal informationOrder action, camera, speed, force and stop, then list protected details from the image.
- Choose mode and reviewCheck subject structure and motion first, followed by camera path, style and end-frame alignment.

Kling V1.5 FAQ
What is Kling V1.5 in Flux Art?
Kling V1.5 is an image-to-video-only workflow in the current Flux Art integration, supporting first-frame, last-frame and start-and-end-frame control.
Does Kling V1.5 support text-to-video?
No. The current configuration does not expose text-to-video for Kling V1.5.
Which modes support first-frame video?
First-frame image-to-video supports Standard and Pro modes.
Which modes support last frame and boundary frames?
Last-frame and start-and-end-frame routes are Pro only.
Does Kling V1.5 provide adherence and negative prompts?
Yes. Current image-to-video workflows expose prompt-adherence and negative-prompt controls.
How should a first-frame prompt be written?
Describe only what happens after the image: chronological action, camera, force and protected details.
How should a last-frame prompt be written?
Work backward from the target image, describing how subject and camera arrive and stop in exact alignment.
How should start and end frames be used?
Let the two images own the boundary states, while the prompt owns path, speed, physics and continuity between them.
Can results be used commercially?
Commercial use depends on current Flux Art and model-provider terms and your rights to prompts and reference media. Check the latest terms before client work.
