TeX2Vid converts LaTeX research papers into narrated source-grounded videos. With four video formats: Teasers, Shorts, Highlights, and Video Abstracts, every claim, result, figure, table, are sourced from the paper. Teasers and Shorts are suitable for social media and Highlights and Video Abstracts can be submitted to conferences and journals. The users can edit slides, swap figures, record their own voice or use default AI voice.
