ScriptViz - An AI-powered script visualization tool developed by Stanford University

What is ScriptViz?

ScriptViz, developed by researchers at Stanford University, is a script visualization tool based on the large film database MovieNet. It retrieves matching movie scenes from script text and dialogue, transforming the screenwriter's written descriptions into concrete visual images. The tool offers precise control over visual elements, allowing screenwriters to set fixed and variable attributes to generate visual references closely aligned with the script descriptions. Screenwriters can intuitively see the visual effects of scenes during the writing process, more accurately expressing the story's emotions and atmosphere, thus enhancing the creative experience. The ScriptViz interface includes a script editor and visualization panels, allowing users to input script details and preview movie scenes in real time. It aims to help screenwriters and film industry professionals improve the visual quality and narrative coherence of their scripts.

ScriptViz's main features

• Visual material retrievalBased on the script, relevant movie footage is retrieved from the MovieNet database.
• Script and visual matchingMatching dialogue and scenes in the script with retrieved visual materials provides screenwriters with intuitive visual references.
• control PanelIt supports users to generate visual representations by specifying specific lines, character traits, locations, etc. in the script based on SQL statements.
• Story AnalysisIt provides advanced visualization of the script, helping to analyze plot development and identify inconsistencies in the story.

ScriptViz Technical Principles

• Database preprocessing: Perform frame-level annotations on movies in the MovieNet database, including attributes such as scene, character identity, gender, and age.
• Visual text similarity calculationThe CLIP model is used to calculate the similarity between script text and visual frames, and to evaluate the degree of matching between frames and script descriptions.
• Identifiability scoreCalculate a location and time identifiability score for each frame to ensure that the retrieved frames clearly show the locations and times specified in the script.
• Dialogue alignment visualizationMatch each line of dialogue in the script to the corresponding visual frame to ensure that the characters mentioned in the dialogue are visible in the frame.
• User interface interactionBased on the user interface, screenwriters input and modify the script in real time, and ScriptViz generates new visual outputs based on the input.

Application scenarios of ScriptViz

• script developmentWhen screenwriters are initially brainstorming a script, they use ScriptViz to transform the scenes, dialogues, and characters in the script into visual images, which allows them to more clearly imagine and plan the visual effects of the story.
• Mood and Atmosphere SettingProviding specific visual references, ScriptViz helps screenwriters capture and enhance specific emotions and atmospheres in a script, such as suspense, romance, or tension.
• Scene refinementThe screenwriter used ScriptViz to explore the visual possibilities of different scenes, such as choosing different locations, times, and character configurations, to refine and optimize the script.
• Character DevelopmentScreenwriters use tools to visualize characters' appearances and behaviors, gaining a deeper understanding of their personalities and motivations.
• Storyboard and Pre-visualizationIn the early stages of film production, ScriptViz assists in creating storyboards and pre-visualization materials, providing directors and production teams with a visual representation of the script.
