How to avoid screen flickering while screen recording

i'm using a video screen recorder and I want to know how to avoid the flickering of the cursor or the slight pauses at every frame record, is it possible?

If you're using CamStudio, It's well worth the time to read the Help files.

Options>Video allows you to change the frame rate.

Options > Cursor Options will control the cursor.

I used to use camstudio and every time I prepare to record an area of my screen (where is located with a green frame), my screen becomes flicking. I can do nothing but restart my computer.

Now I use demo creator instead. I got it for free by writing a review for its trial version.
