• The model supports four input modalities (text, image, audio, video) and offers extensive multi-modal content reference and editing capabilities.
• Native output durations range from 4 to 15 seconds at 480p and 720p resolutions.
• A 'Fast' version is available for low-latency scenarios, boosting generation speed.

Research Evidence

Aim: To develop and evaluate a novel multi-modal audio-video generation model that integrates diverse input modalities and offers advanced editing features for enhanced creative output.

Method: Model Development and Evaluation

Procedure: A new unified, large-scale architecture was developed for multi-modal audio-video joint generation, supporting text, image, audio, and video inputs. The model was integrated with comprehensive multi-modal content reference and editing capabilities. Performance was assessed through expert evaluations and public user tests, comparing it against existing leading models. Specific versions were developed for standard and low-latency generation, with defined output durations and resolutions.
