I like Loilo featuresLoilo. Features that you might like include:
- Free
- No watermark unless you use the trial editing software. (In my case I plan to use Windows movie maker when the trial is over)
- You can record as long as you want I record pretty long videos.
- For me I found it seemed to use less resources then Fraps and Bandicam when recording. May depend on settings of all software)
I tried a few others and this was the only one that seemed to work well. The only caveat is that it comecomes bundled with a trial for video editing software.
