Checked against the linked sources on September 3, 2026; no editor scores here ( how we rate ). ## How is reference-to-video different from image-to-video? In image-to-video the picture is the opening frame and the subject may drift as the camera moves. In reference-to-video the images act as an identity embedding: the model encodes the subject’s face, body or shape and conditions every frame on it while the prompt decides scene, camera and action. The same person can appear in a room that was in no input. Vidu’s API documentation states that the endpoint “accepts 1 to 7 images,” with image and text subjects capped at 7 in total. Kling calls the equivalent asset an Element — “a composite asset” built from multiple angles — and binds up to 3 elements to a start frame or start-and-end pair in the 3.0 model. ## Which models offer it? Vidu (Shengshu) exposes reference-to-video across its Q3, Q2, Q1 and 2.0 models; Q3 adds audio and 3–16-second clips at 540p to 1080p. Kling 3.0 supports up to 7 reference characters in video. Veo 3.1 calls the feature Ingredients to Video, uses 1–3 reference images and marks output with SynthID . Model entries: Vidu , Kling , Veo , Wan . ## Why is identity locking a consent issue? Image-to-video degrades a likeness over time; reference-to-video preserves it. That makes it valuable for film work and dangerous for intimate content: a few ordinary photos can place a real person into a scene they never took part in.
