Abstract: Academic presentation videos have become an essential medium for research
communication, yet producing them remains highly labor-intensive, often
requiring hours of slide design, recording, and editing for a short 2 to 10
minutes video. Unlike natural video, presentation video generation involves
distinctive challenges: inputs from research papers, dense multi-modal
information (text, figures, tables), and the need to coordinate multiple
aligned channels such as slides, subtitles, speech, and human talker. To
address these challenges, we introduce PaperTalker, the first benchmark of 101
research papers paired with author-created presentation videos, slides, and
speaker metadata. We further design four tailored evaluation metrics--Meta
Similarity, PresentArena, PresentQuiz, and IP Memory--to measure how videos
convey the paper's information to the audience. Building on this foundation, we
propose PaperTalker, the first multi-agent framework for academic presentation
video generation. It integrates slide generation with effective layout
refinement by a novel effective tree search visual choice, cursor grounding,
subtitling, speech synthesis, and talking-head rendering, while parallelizing
slide-wise generation for efficiency. Experiments on Paper2Video demonstrate
that the presentation videos produced by our approach are more faithful and
informative than existing baselines, establishing a practical step toward
automated and ready-to-use academic video generation. Our dataset, agent, and
code are available at https://github.com/showlab/Paper2Video.
