Kalmuri runs without installation and is suitable for USB use.

How do I record videos using Kalmuri?

To record video with Kalmuri, you choose the MP4 option from the output menu. In portable versions, you need to manually place an FFmpeg.exe file in Kalmuri's folder – once it's there, the program supports high-quality video recording as long as FFmpeg is recognized.
