Start & End Frame
Define the first and last frame.
Drop in two images and King AI generates the motion in between. Perfect for transitions, morphs, music videos, and any time you need precise control over how a clip starts and ends.
Highlights
Total control over the in-between.
You set the endpoints; King AI invents a natural path between them.
Photo-to-photo morph
Smoothly morph between two photos with natural motion.
Time-lapse transitions
Show a sunrise, a build, or a transformation in one shot.
Music-video cuts
Generate a single seamless transition between two scenes.
Extend further
Chain with the extender for longer sequences.
How it works
Start & end frame in four steps.
Upload two images
Pick a start frame and an end frame — photos, generations, or video stills.
Add a transition prompt
Optional — describe the motion, or let King AI invent it.
Generate
King AI plans the in-between motion and renders the result.
Refine and export
Tweak duration, model, or seed until the transition is right.
Models
Frame-capable video models.
Switch models per generation, run several at once, and compare results side by side. New models ship the day the labs release them.
FAQ
Start & end frame, answered.
Do I need to write a prompt?
No. Start & End Frame works with just two images. You can add a prompt to guide the motion, but it's optional.
How long can the transition be?
Up to 10 seconds per transition. Use the AI Video Extender to continue the motion if you need more time.
What can I use it for?
Photo-to-photo morphs, time-lapse transitions, seamless music-video cuts, and any moment where you need precise control over how a clip starts and ends.
Which models support start and end frames?
King AI routes to frame-capable engines such as Veo 3.1, Sora 2 Pro, Kling V3 Pro, Hailuo 2.3 Pro, and WAN 2.7.
