Seedream 4 Features & Overview

Seedream 4 is an AI video creation system for teams that need control and repeatability. It converts text, images, or rough clips into coherent shots with stable motion, consistent subjects, and directable cameras. The workspace pairs diffusion and video transformers with depth, segmentation, and reference guidance. You direct motion and style, lock identities across shots, apply regional fixes with masks, and export passes that slide into standard editing and VFX flows.

Core Features

• Text to Video and Image to Video: Generate shots from prompts or animate a single photo into a full scene. The model respects layout and lighting, and stabilizes motion across frames so fast edits avoid shimmer and jitter.
• Camera Motion Controls: Pick dolly, orbit, crane, or handheld styles, then set speed and easing with keyframes. You land predictable starts and finishes, which makes beats easy to cut on a multi-shot timeline.
• Character ID and Consistency: Define a character once and reuse it across scenes. Identity locking preserves face, hair, and wardrobe while allowing new poses and locations, so campaigns keep continuity without manual touch-ups.
• Masking, Inpainting, and Object Swap: Paint regions to fix artifacts, replace items, or change apparel. The editor blends edges, matches grain, and preserves shadows, which keeps spot edits invisible during close review.
• Style and Look Controls: Apply preset looks or reference an image to steer palette, texture, and grain. Weight controls keep brand color and contrast aligned across shots while leaving room for tasteful variation.
• Depth and Matting Passes: Export depth and alpha along with the render. Compositors add 3D text, fog, or glows in an NLE or node graph, and keep clean subject boundaries during relights and overlays.
• Storyboard and Multi-shot Timeline: Outline scenes, set durations, and chain shots into a rough cut. You revise per-shot prompts and motion notes while preserving overall timing for explainers, ads, and trailers.
• Video to Video Refinement: Feed a rough take and request a cleaner version. The model maintains blocking and timing, improves lighting and texture, and reduces noise so the result feels closer to a final pass.
• Audio and Voice Options: Add scratch voiceover, auto-time captions, and review a side-by-side script. Quick lip-sync tools align speech with mouth shapes for social posts and fast localizations before the final mix.
• Batch Jobs and Credits: Queue many renders with per-shot parameters and estimated cost. Each job records seed, prompt, and settings, which makes successful looks repeatable across campaigns and teams.
• Safety and Rights Controls: Watermark outputs, restrict risky prompts, and keep a signed run log with thumbnails and hashes. Reviewers track usage and archive approved cuts to meet internal policy.
• Developer API: Trigger generations, poll status, and fetch files programmatically. Webhooks and signed URLs connect Seedream 4 to asset managers, CI pipelines, and custom production tools.
