Summary
A GitHub repository (upenn/web-scroll-video) provides a tool called Web Scroller that creates MP4 videos of web pages scrolling at a steady speed. It uses headless Chrome to capture viewport screenshots at fixed scroll offsets and streams them into ffmpeg to produce 1080p H.264 MP4 videos. The tool integrates with Codex AI to allow users to describe videos in plain English, generating cue sheets and rendering MP4s that are easy to revise.
Key quotes
· 4 pulledCreate an MP4 video of a web page scrolling at a steady speed.
The tool opens the URL in headless Chrome, captures viewport screenshots at fixed scroll offsets, and streams those frames into ffmpeg.
The default output is 1080p: 1920x1080, 30 fps, H.264 MP4.
Codex will create a cue sheet, render the MP4, and keep the cue sheet and video together so revisions are easy.
