NVIDIA Virtual Reality Capture and Replay (VCR) enables developers and users to accurately capture and replay virtual reality (VR) sessions for performance testing, scene troubleshooting, and more.

Attempting to precisely recreate a user’s VR experience—e.g., for QA or debugging—is time consuming, and sometimes may not even be possible. VCR makes replaying VR sessions both accurate and painless. The tool records time-stamped head-mounted display (HMD) and controller inputs during an immersive VR session. Playback is 1-click as well and can be viewed on the desktop without having to use the VR HMD. In addition to supporting recording and playback, VCR also comes with a C++ API, so developers can read, edit, and write VCR session files. With just a few lines of code, you can re-time a session, slowing down or speeding up different parts of the action; you can edit controller inputs; and you can even filter controller and HMD tracking data to remove noisy motion. VCR streamlines the recording, playback, and editing of VR sessions.
