While recording a crt monitor displaying pal material (50 hz) with a shutter speed other than 50 these kind of distortions will appear. Shutter speed 100.
 
Correct shutter speed = 50. For NTSC it would be 60.  
 
The Shoot – Setting up the equipment

Shutter speed
In low light situations use 50 as shutter speed for SD (standard definition) PAL. Lower than that will smear the image unnecessarily. In the worst case scenario and when the camera is not moving too much it can be worth trying 25, but avoid this if possible. Also avoid fast shutter speeds as they look strange and create a strobe effect.

A problem one might encounter while documenting video installations with monitors is the discrepancy between PAL and NTSC. As the former is 50 Hz and the latter is 60, or 59.94 to be exact, and trying to film a NTSC on a PAL camera will give a flickering and striped image. The best solution is to change the source discs to PAL versions if possible. Otherwise one has to experiment with the shutter speeds to try to get rid of the problem.
