First Last Frame to Video Generator — Turn Two Keyframes Into a Smooth AI Clip

Every other first last frame to video tool funnels you into a single model and a single style of in-between motion. GenMix's first last frame to video generator lets you upload your two keyframes once and try Wan 2.7, Wan 2.2, Veo 3.1, and Seedance 2.0 side by side without re-uploading anything. Compare three or four motion interpretations of the same start-and-end frame combination in 5 minutes — see which engine reads your specific keyframe pair best, then keep the winner. No separate logins, no separate billing, no re-uploading the keyframe pair every time you switch engines, no per-model paywalls. The first last frame to video generator routes your keyframe pair, prompt, and credit balance through one unified interface.

A simple crossfade dissolves between your first frame and last frame and looks cheap — a glorified Premiere transition that destroys subject identity. Real frame interpolation ai video is different. The model in the first last frame to video generator understands what the subject is doing, what the camera is doing, and what the scene logic implies between the two keyframes. It generates physically plausible motion frame by frame: a character walks rather than morphs, a sky shifts hue rather than fades, a product rotates rather than wipes, a face turns naturally rather than crossfades through ghosting. The first last frame to video generator preserves anatomical continuity, lighting direction, and color grading across every intermediate frame.

Generate both keyframes with Midjourney, Nano Banana, GPT Image, Seedream, or Flux Kontext, then bring them straight into the first last frame to video generator. The pipeline preserves the original style, color grading, and composition of both keyframes — so the AI-filled motion in between looks like it belongs to the same shot, not stitched together from two different stylistic worlds. This image to video with end frame workflow is one of GenMix's most-used setups: creators generate a 'before' state and an 'after' state with their favorite image model, then let the first last frame to video generator handle the transition. The result is a complete AI-native pipeline from concept to motion clip without leaving GenMix.
