Summary: Atlas Cloud is integrating SkyReels-V4, the world’s #2 video foundation model, bringing native audio-visual synchronization to mainstream workflows. Beyond text-to-video, it offers pixel-level control via image and mask references. The SkyReels-V4 API on Atlas Cloud ensures high-fidelity 1080p output with optimized inference costs for creators and agencies.
Introduction
Atlas Cloud is dedicated to empowering creators with the world’s most advanced generative AI capabilities. We are thrilled to announce that the highly anticipated video foundation model, SkyReels-V4, will soon be officially integrated into our platform.
Developed by Kunlun, SkyReels-V4 recently secured the #2 spot on the prestigious Artificial Analysis Global Text-to-Video (with Audio) Leaderboard. It shatters the traditional, fragmented workflow of "generating visuals first, adding sound later." By utilizing full-modality referencing and unified generation, it offers creators unprecedented creative freedom.
- Core Strengths: Precision multimodal control, high-fidelity audio-visual synchronization, and pixel-level video restoration/editing.
- Target Audience: Film post-production houses, marketing agencies, and short-form content creators.
- Status: Launching Soon.
Core Features
While most existing models are limited to text-to-video prompts, SkyReels-V4 represents a generational leap across three key dimensions:
Native Audio-Visual Co-Generation
Forget the tedious process of manual post-production layering. SkyReels-V4 processes video and audio simultaneously within a single architecture. Whether it is frame-perfect lip-syncing or SFX (sound effects) aligned precisely with footsteps and movements, everything is synchronized at the microsecond level. This significantly reduces the time and cost spent on sound design and manual dubbing.
Multi-Dimensional Multimodal Control & Editing
SkyReels-V4 doesn’t just "read" text; it "understands" images, video clips, masks, and audio references. This allows for incredibly complex local modifications. Creators can now edit video with the precision of a photo editor—no more "re-rolling" the entire prompt for a minor change.
Cinematic Quality & Long-Sequence Stability
Through innovative engineering solutions, the model delivers stable, 1080p resolution at 32 FPS for sequences up to 15 seconds. It achieves cinematic high-definition visuals while maintaining highly efficient compute consumption.
Application Scenarios
Film & Narrative Storytelling
- Scenario: Character replacement or style transfer in post-production where camera movement, lighting, and action must remain identical to the original plate.
- Prompt Example: "Replace the dancing woman on the left of the reference video with the dog from Reference Image 1. Replace the dancing man in the suit on the right with the cat from Reference Image 2. Ensure all movements remain perfectly synchronized."
- Result: The model flawlessly transfers the textures and anatomy of the animals, even ensuring their "dance steps" hit the beats of the original background music.

Marketing & Social Media Operations
- Scenario: Rapidly iterating on existing assets to add commercial products or "clean" a scene of unwanted elements.
- Prompt Example: "Remove the young man with short blonde hair holding a flashlight on the far right, and the woman with long curly blonde hair in the deep purple top."
- Result: The model achieves natural, seamless object removal and integration. Whether it’s adding a hat that moves realistically with a dancer’s physics or clearing a cluttered background, it transforms how commercial content is repurposed.
四、 Why Use SkyReels-V4 on Atlas Cloud?
