About This Tool

This tool captures runtime video, audio, and screen activity for debugging, documentation, training, and QA. Primary users include developers, testers, educators, technical writers, and support engineers who require reproducible sessions. It records software interactions, user flows, or demonstrations to preserve exact steps and signals.
Conceptually, recording involves selecting capture sources, encoding streams, and exporting a synchronized video file. The system uses H.264 with AAC by default, with adjustable bitrate and resolution; it can operate offline, store locally, or export to cloud storage. A lightweight real-time preview ensures developers can confirm framing without heavy processing.
Unique value lies in simplicity, determinism, and compatibility across Windows, macOS, and Linux. By focusing on runtime capture rather than post-processing, teams can document workflows, reproduce failures, and train users with authentic recordings. Typical use cases include software tutorials, bug reproduction steps, technical demonstrations, and evidence for compliance.
Core features include multi-source capture, optional webcam overlay, format choices, and metadata tagging.

Frequently Asked Questions

Find Quick Answers

What platforms are supported?

The tool runs on Windows, macOS, and Linux with desktop capture permissions; it supports common GPUs and CPU-based encoding, and relies on local storage by default.

Can I record system audio and microphone simultaneously?

Yes. You can enable both audio_input and system_audio channels; if system_audio is unavailable, recording continues with microphone.

What file formats and codecs are used?

Outputs default to MP4 with H.264 video and AAC audio; other formats (WEBM, MOV) are supported if configured. Bitrate and keyframe interval can be adjusted.

How is privacy handled?

The tool captures only user-selected sources; permissions must be granted; recordings are stored locally or in chosen cloud storage if configured; no data leaves the device without user action.
