AI Keyframe Video Generator Free — First & Last Frame
Upload two images — a start frame and an end frame — and AI generates a stunning video that transitions between them. Morphing, transformations, time-lapses, and reveals. Free to start, 1080p, no video watermarks.
Two Images. One Video. Zero Effort.
No credit card required. Define your start and end, AI creates everything in between.

AI keyframe video generation lets you define two key moments — a starting image and an ending image — and the AI automatically generates all the frames in between. This creates a smooth video transition from your first frame to your last frame, with realistic motion, morphing, and visual transformation.
This is fundamentally different from a crossfade. A crossfade blends opacity. AI keyframe generation creates entirely new visual content — a construction site gradually becoming a finished building, a landscape transitioning from summer to winter with falling leaves and accumulating snow, a face aging naturally across decades. The AI generates the journey, not just the blending.
Other platforms call this "Keyframe Control" (Runway), "Start/End Frame" (Kling), or "Keyframes" (Luma). On ZSky AI, we call it First Frame Last Frame (FFLF) — because you define the first frame and the last frame, and AI fills in everything else.
How It Works
Step 1: Upload your first image. This is where your video starts — a before photo, a starting scene, or an initial state.
Step 2: Upload your last image. This is where your video ends — the after photo, the destination scene, or the final state.
Step 3: Add a motion prompt (optional). Guide the transition style: "slow cinematic morph," "rapid transformation with particles," "natural time-lapse progression."
Step 4: Generate. The AI processes your images on dedicated RTX 5090 GPUs in 30-90 seconds. No queue, no shared cloud.
Step 5: Download. Get your 1080p MP4 with audio. watermark-free video, commercially licensed, ready for any use.
