Screen recorder, records nothing ( empty video

[Lokoso]

Hi everyone, when i try to record my screen with a screen recorder it just records a empty video with a black screen, the videos has its full length its just black..

Tryed quite a few recorders now and they all record nothing but black, have any of you experienced this?

EDIT: It records audio and the curser.. !?

Have you actually selected an area to record before recording? Because the screenshot states the video's dimensions as 0 x 0 pixel.

I never had a problem with ScreenFlow recoding anything.

Jep just tryed with a Fullscreen record, says the same thing Decoder, 0 pixels x 0 Pixels, 0-bit colors.
