FAQPage Schema

How do I record a Chrome tab to video from the command line?▼

Record a Chrome tab via CLI by running node record.js start --tab 1 --out demo.mp4. A WebSocket bridge and Chrome extension capture frames at 5 FPS, encoding the output to MP4 or WebM.

Does screen recording with ffmpeg work for browser automation workflows?▼

Screen recording with ffmpeg supports browser automation by capturing Chrome tab frames in real-time and encoding them to video. This enables end-to-end capture workflows for documentation, demonstrations, and debugging in development and QA contexts.

Can I add captions to a screen recording via CLI?▼

You can add captions to a screen recording via CLI using the on-demand captions feature. When you start a recording, the tool outputs an MP4 or WebM video file accompanied by a separate captions file.

Do I need a Chrome extension to capture browser tabs to video?▼

You need a Chrome extension to capture browser tabs to video because it provides the real-time frame capture mechanism. The extension communicates through a WebSocket bridge to the CLI, which uses ffmpeg-static to encode the 5 FPS frames into MP4 or WebM.

What is the best way to automate screen capture for QA debugging?▼

The best way to automate screen capture for QA debugging is using a CLI tool that records Chrome tabs to video, lists available tabs, and queries recording status. This approach integrates into automated testing pipelines to capture end-to-end workflows as MP4 or WebM files.
