Hello,

 

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.

 

 

 

 

Thanks

In a word, no. To solve this properly you need either a camera with a global, rather than rolling, shutter, or a strobe that can be synchronised to the camera. Unfortunately, there is no camera setting which will always avoid torn frames - you might get lucky, but then you might not.

Is this "project" a school assignment?  From what I read in Phil's posting, anyone who reports success on the bit of homework would have cheated.
