Answers.Text: As it is stated in the question the aperture is set to max and the iso also. Shutter and FPS are set to these values to achive the effect.

Comments.Text: Yes. 'The only solution to put more light', so 1/1000 of a sec collects enough to create an image from it. You can put more light by strobes or flashes, or just switch another lamp on, but _you need more light_

Comments.Text: Maybe use a faster lens?  If you're using a compatible lens mount, you could try a metabones speedbooster.  Aperture, shutter, ISO, ND, actual light.  Those are the 5 things you can change.

Comments.Text: "Is the only solution to put more light?" - you can get a more sensitive camera like the Sony a7s. As an a side, 25 fps at 1/1000 would be hard to watch.

  I'm trying to film guitar strings moving. So, I'm putting high shutters peed (1/1000) and slow frame rate (25). This is working. But the problem is when I'm doing it in the evening. The image is to dark. I'm putting iso up to the limit and open the lens to the maximum.
  
  Is the only solution to put more light??
