I'm not going to show you how to capture smooth and fluid screencasts with sixteen open Firefox browsers and a 3D calculator running in background. No, here are simple hints that may help some users improve the quality of their contents.

1. Close the main running applications before recording to gain fluidity.
2. Avoid fullscreen recordings for video recapture and complex 3D images.
3. Avoid to move your mouse too fast during the recording.
4. Avoid to use your mouse scroll wheel. Prefer the Page Down / Page Up arrows.
5. Avoid to move the windows of your navigator.
6. Avoid to use the scrollbar on your navigator.
7. Avoid to capture ads with lots of animations.
