Captail
What it is
Captail is a free Windows utility for saving recent gameplay with instant replay. It keeps a rolling capture buffer and monitors its capture pipeline for stalls; if modules stop or frames go missing, a watchdog attempts a controlled restart with retries and backoff. Desktop mode records a selected monitor and can use Game Capture when available, while Game Capture mode does not record the desktop. Depending on detected hardware encoders, Captail offers AV1, HEVC, and H.264 through NVIDIA NVENC, AMD AMF, or Intel Quick Sync. Audio can be mixed or split into separate or per-application tracks, with independent microphone routing. Replay duration can be set from 15 seconds to 15 minutes, with an optional RAM limit and requested capture rates from 30 to 240 FPS. The replay player provides seeking and playback-speed controls, and the multi-track editor supports trimming and merging audio tracks. Captures, settings, thumbnails, and logs stay on the PC. Captail supports Windows 10 version 2004 or later and Windows 11 on x64.
