What Momento is

Momento is a free, open-source game recorder for 64-bit Windows 10 version 1903 or newer and Windows 11. It watches a configurable list of games and starts recording when a matching game window appears. Capture uses Windows Graphics Capture and can include microphone and system audio. Recordings stay on the computer in MKV format; the built-in editor can browse, search, preview, repair, and trim clips, then export them as MP4 without re-encoding. A configurable bookmark hotkey defaults to F8.

The standard public build has no account, telemetry, analytics, advertising, automatic uploads, or cloud library. Optional YouTube uploads require users to create a Google Cloud Desktop OAuth client and import its JSON file. The imported client details and account token are stored separately in DPAPI-encrypted files. Installed builds check GitHub Releases at startup and verify signed release metadata, installer size, and SHA-256 before accepting updates. The app uses about 300 MB of installed disk space, with additional room needed for recordings. At default settings of 60 fps and 16,000 kbit/s, recordings use about 7.2 GB per hour before audio and container overhead. Momento does not provide replay buffering, streaming, webcam capture, or HDR recording.
