Our Review:

Krut in particular works well though it can only output video files in .mov and audio in .wav formats. However, the output files can readily be converted to other formats using free conversion sites like Zamzar and YouConvertIt. There are some traps with Krut, particularly with video card and sound card settings.

In comparison to other streaming media recorders in this category, Krut delivers almost the same good quality as Jing and further shines at recording streams, almost without interruptions, which usually come in the form of short time delays measured in milliseconds.
