How to Choose an Image to Video API

First and last frame control

Wan 3.0 takes a required first frame with an optional last frame, while Seedance 2.5, Gemini Omni 1.1 Flash, Kling V3 and MiniMax Hailuo also accept start and end frames to control how a shot begins and ends.

Multiple reference images

Seedance 2.5 accepts up to 50 multimodal references, FLUX 3 Video uses 1–10 ordered keyframes, Grok Imagine Video takes up to 7 images and Kling Video O1 up to 2 for style and character control.

Subject and character consistency

Kling V3, Seedance and Wan models animate a reference image while keeping the subject recognizable, a good fit for product shots, avatars and e-commerce clips.

Image to video with native audio

Veo 3.1, HappyHorse 1.0 and SkyReels V4 add synchronized sound to the animated image, so one request returns a clip ready for social or ads.
