kling-2-1/standard/image-to-video
Animate a single image into a smooth video with Kling 2.1 Standard.
Happy Horse 1.1 Image to Video reads one source photo plus a short prompt and returns a coherent clip, keeping the subject's identity, color, and framing close to the original frame while adding believable motion.
This release sharpens the weak spots of the 1.0 generation. Action that used to feel sluggish now carries more pace and weight, and a wider range of faces — including Asian faces — holds a steadier likeness across the shot.
Output format: resolution 720P or 1080P / fps 24 / duration 3-15s / input a single still image / aspect ratio follows the source image (no separate ratio control).

Happy Horse 1.1 Image to Video animates a single still photo into a short clip with natural, physically grounded motion while keeping the subject's identity, color, and composition close to the original frame. It suits portrait animation, product reveal clips, and cinematic ad teasers where you want to bring a specific image to life rather than generate a scene from scratch.
Happy Horse 1.1 Image to Video refines known pain points from the 1.0 generation, with livelier motion pacing instead of sluggish action and steadier handling of diverse subjects, including improved Asian-face fidelity. Based on publicly available information, these changes make it a more dependable choice for character-driven and product-driven clips.
Yes. Happy Horse 1.1 Image to Video uses your uploaded photo as the first frame, then adds motion from your text prompt. If you want prompt-only generation without a source image, use the Happy Horse 1.1 text-to-video template instead.
Happy Horse 1.1 Image to Video outputs 720P or 1080P at 24 fps, with clip lengths from 3 to 15 seconds. The output aspect ratio follows your source image, so there is no separate ratio control — choose your photo's proportions to control the final shape.
Lead with motion verbs like drift, orbit, or push in so the model knows what should move, then state what must stay fixed, such as identity, packaging, or background. Because Happy Horse 1.1 Image to Video animates your exact photo, describing one clear visual beat per clip gives the most reliable results.
The model takes one first-frame image (JPEG, JPG, PNG, or WEBP; min 300px per side; aspect between 1:2.5 and 2.5:1; max 10MB) plus a prompt up to 5000 non-Chinese or 2500 Chinese characters. Check the current RunComfy parameter panel for the exact limits, since some options may vary by provider settings.
