Action! is Windows software for recording gameplay and streaming live, rather than a game itself. It captures games as well as the full desktop, a selected desktop region, application windows and web-player video, bringing several kinds of recording into one tool.
For gameplay, Action! supports DirectX, OpenGL, Vulkan and UWP titles, with video recorded directly to MP4 using H.264/AVC or H.265/HEVC. Hardware acceleration options include Intel Quick Sync Video, NVIDIA NVENC and AMD AMF. A multi-layer on-screen display can show recording or stream status and place a chat overlay over streamed games; users can also add a webcam, microphone commentary and custom graphics.
The tool combines capture with practical production and diagnostic features: it can display and benchmark frame rates, save benchmark results, mix microphone and system audio into separate tracks, and provide a live preview of the video composition. Its distinctive focus is an integrated recording and streaming workflow, with a built-in player and export options alongside capture controls.
