I am about to start shooting a project that requires me to use a strobe [a standard canon flash] whilst shooting video.
The strobe will will be the only source of light in the scene.
I am shooting this with a canon dslr.
I have tried this before and have noticed that for some reason the strobe causes an issue with the image where the screen gets divided into 2, I know that this has something to do with the shutter speed /flash frequency I am setting on my camera/flash but I do not know how to solve this.
Is there any "correct" shutter speed I can use that will allow me to use the strobe without causing such problems.
