What CamStudio is
CamStudio is a free Windows screen recorder that captures computer activity and creates MP4 videos for tutorials, demos, and presentations. It can record the full screen, one window, or a selected region. CamStudio 3 supports H.264, H.265/HEVC, and AV1 video codecs, with controls for recording limits by time or file size, resolution, and frame rate. It captures system audio or audio from a designated application, with AAC and FLAC among the supported output formats. Microphone recording is temporarily disabled. CamStudio V3 runs without an installation wizard or setup, but requires 64-bit Windows 10 or 11, at least 4 GB RAM, DirectX 11-compatible graphics, 1 GB of free disk space, and administrator access at first launch. The maker says V3 is distributed exclusively from camstudio.org and is not bundled with third-party software. CamStudio was originally released as open source by RenderSoft in 2001; the current maintainer later developed V3. The listed CamStudio plan is free, with no subscription costs or paywalled premium features.
