OmniRec
What OmniRec is
OmniRec is a free, MIT-licensed open-source screen recorder for Linux, Windows, and macOS. It captures a single window, an entire display, or a custom region, and records system audio, microphone audio, or both with dual-source mixing and echo cancellation. Automatic speech transcription creates a timestamped Markdown transcript beside the video. Transcription uses whisper.cpp through vtx-engine and downloads the default ggml-medium.en model, about 1.5 GB, on first use. Export formats include MP4, WebM, MKV, QuickTime, GIF, APNG, and WebP. The project describes local processing, with recordings staying on the user's machine. Its README covers recording Zoom, Teams, or Google Meet calls using system audio and a microphone. A command-line interface supports headless recording and automation. The free plan is listed as free, with no subscriptions, accounts, or limits. The project is in active development and not yet available for general use.
