What Is SkyReels-V4 Multi-modal Video Foundation Model?
SkyReels-V4 is the next-generation multi-modal video foundation model for joint video audio generation, inpainting, and editing within a unified dual-stream MMDiT architecture. The model processes text, images, video clips, masks, and audio references as inputs, producing 1080p video at 32 FPS for up to 15 seconds with synchronized audio. A channel concatenation formulation enables native inpainting tasks within the generation pipeline, making this ai video generator far more versatile than SkyReels V3 and competing tools. Every skyreel output benefits from cross-modal attention between visual and auditory streams.
SkyReels-V4 Text-to-Video and Audio Generation
This ai video generator transforms text prompts into cinematic videos with synchronized audio in a single forward pass. The dual-stream MMDiT jointly models visual and auditory tokens, producing output that is temporally aligned at the frame level. Each skyreel clip renders at 1080p and 32 FPS with accurate motion and matching soundscapes.
SkyReels-V4 Image-to-Video with Audio Sync
Upload a reference image and the model transforms it into dynamic video with realistic motion and synchronized audio. The multi-modal input encoder conditions generation on visual references, producing smoother transitions than any previous skyreel model while generating matching soundscapes through the dual-stream pathway.
SkyReels-V4 Multimodal Input Support
Accepts text, reference images, video clips, binary masks for video inpainting, and audio references to guide generation. The channel concatenation formulation blends all input modalities within the dual-stream MMDiT, giving this skyreel model far more context than text-only systems for producing unified video and audio output.
SkyReels-V4 Native Audio Synchronization
Native audio synchronization is powered by the dual-stream MMDiT that jointly generates video and audio tokens. This approach ensures lip movements match speech, environmental sounds align with visual events, and musical scores follow the emotional arc. The result makes every skyreel output ideal for talking-head content and narrative films.
Why Choose SkyReels-V4 Over SkyReels V3 and Other AI Video Generators
SkyReels-V4 provides a unified foundation model for video audio generation, inpainting, and editing — surpassing SkyReels V3 with dual-stream MMDiT, 1080p at 32 FPS, and native audio sync.
