A presenter stands at a lectern in a conference room, delivering a talk on the latest advancements in video generation techniques. A large screen behind him displays a tree diagram illustrating different categories and methods within the field of video generation. The diagram is divided into main branches such as 'Pioneering Works,' 'Open-Source Base Models,' 'Other Closed-Source Works,' 'Training-Efficient Techniques,' 'Storyboard,' and 'Long Video Generation.' Each category includes various methodologies and models with their respective references. Attendees are seated attentively, with one person in the foreground with their back to the camera, closely following the presentation. The setting suggests an academic or industry conference dedicated to advancements in artificial intelligence and video generation.
