Using Kalmuri portable for video recording

Kalmuri’s portable version doesn’t include FFmpeg, which is required for video recording. Without it, you’ll get an “error FFmpeg.exe not found” message. To fix this, download FFmpeg from the provided link, extract it, and place FFmpeg.exe in Kalmuri’s folder. Kalmuri will then recognize it automatically, allowing you to start recording in high quality instantly.
