Model overview longcat-multi-avatar/image-audio-to-video generates realistic, lip-synchronized videos from images and audio input. Built by fal-ai, this model excels at creating long-form video content with natural facial dynamics and consistent identity preservation. Unlike single-character alternatives, this model handles multiple avatars in a single generation, making it distinct from longcat-single-avatar/image-audio-to-video. For simpler use cases or audio-only inputs without images, the longcat-single-avatar/audio-to-video variant offers a streamlined alternative. longcat-multi-avatar/image-audio-to-video fal-ai longcat-single-avatar/image-audio-to-video longcat-single-avatar/audio-to-video Capabilities The model synthesizes video content by taking an image of a character and audio narration, then generating synchronized video output where the character's mouth movements match the speech. It maintains consistent facial identity throughout long video sequences while producing natural head movements and expressions that correspond to the audio tone. The system handles multiple characters simultaneously, allowing for scenes with dialogue between different avatars without losing coherence or identity consistency across extended video lengths. What can I use it for? Content creators can use this for producing talking head videos, educational content, and digital presentations without requiring actors or filming equipment. Marketing teams can generate personalized video messages at scale by creating avatars that speak directly to audiences. Virtual streaming and gaming applications benefit from the ability to generate character animations driven by live or recorded audio. Organizations can build interactive AI avatars for customer service, training modules, and entertainment content. The multi-avatar capability enables the creation of conversation scenes and narrative-driven video content with multiple characters. Things to try Experiment with dialogue scenes featuring multiple characters having conversations to test the model's ability to maintain separate identities and coordinate timing. Try using different audio tones and emotional content to see how natural expressions adapt accordingly. Test the boundaries of video length to understand where the model maintains consistency best. Create educational videos with a primary instructor avatar and supporting character avatars for interaction. Generate multilingual content to see how well lip synchronization performs across different languages and speech patterns.
