CamStudio is a free screen recording software that allows you to capture screen activity on your computer and create MP4 video files. It"s perfect for creating video tutorials, demos, and presentations. With CamStudio, you can record all screen and audio activity on your computer and create industry-standard MP4 video files with two different codecs.
CamStudio 3.1 Beta is back after a long break, offering a fully modernized screen recording experience. The software has been rebuilt on the Windows Graphics Capture API, supporting the latest Windows 10 and 11 features. With GPU hardware acceleration, it provides smooth recordings while using minimal CPU, making it a lightweight alternative to larger suites for simple captures.
This update focuses on control and reliability. Users can now pause and resume recordings with a hotkey, see a countdown overlay for delayed starts, and use a command-line interface for automation. The audio system has been updated to separate microphone and system audio, allowing recordings of just your voice, just application sounds, or a mix of both. Modern codecs like AV1 and HEVC help keep file sizes small without sacrificing quality.
Stability has also improved. The new fragmented MP4 format reduces the risk of corrupted files if a recording is interrupted. CamStudio 3.1 features a clean, minimalist interface and avoids unnecessary extras, making it a practical choice for users who need reliable screen recording with straightforward controls.
What do you think—with this massive performance boost and modern feature set, is the new CamStudio still relevant in 2026?
