Script-to-Slide Grounding: Grounding Script Sentences to Slide Objects for Automatic Instructional Video Generation
A new AI system turns slides and scripts into polished instructional videos, achieving a 0.924 F1-score for text grounding.
A team of researchers has taken a major step toward automating the tedious process of creating educational and presentation videos. They have formalized a new AI task called Script-to-Slide Grounding (S2SG), which involves automatically linking each sentence in a spoken script to the specific text box, image, or diagram it describes on a slide. This is the critical first step for a system that could eventually take a PowerPoint deck and a voiceover script and generate a fully-produced video complete with synchronized animations and visual effects.
As a proof of concept, the team developed 'Text-S2SG,' a method that uses a large language model (LLM) to perform this grounding task specifically for text objects on slides. In their experiments, the AI achieved a high performance score of 0.924 F1, demonstrating the feasibility of the approach. While this initial work focuses on text, the formalization of the S2SG task lays the groundwork for future models that can also ground script sentences to images, charts, and shapes, moving us closer to one-click video generation for educators, trainers, and content creators.
- Formalizes the new AI task of Script-to-Slide Grounding (S2SG) to link script sentences to slide objects.
- Proposes 'Text-S2SG,' an LLM-based method that achieved a high 0.924 F1-score for grounding text objects.
- Paves the way for fully automatic systems that generate animated instructional videos from slides and a script.
Why It Matters
This could save educators and professionals countless hours by automating the most labor-intensive part of creating polished instructional video content.
