Screen captures are useful for all sorts for reasons form building tutorials to illustrating software like we do at Softonic. However, there are not many capture utilities out there that also allow you to take shots of video but Capture Solution does. Captures are made in AVI, MOV, RM or WMV video formats with different configuration options: ratio of frames per second, colour depth, width etc.
You can capture a whole lot more than that too. If you wish, you can also capture the cursor, the sound recording and even include a logo in the capture. Alternatively, you can capture from a device connected to your hardware such as a TV Tuner or Webcam. I also like the fact that you can see immediately what you've captured during a session via the integrated video viewer because it gives you a good overview of a selection of shots you've chosen for a game.
Screen capturing is not rocket science but the fact that this also takes video means that it's definitely up there with my first choice capture tool.
