Hi Omar, get yourself one of these, there are a few Brands around it doesn't need to be this Brand, B+W make them as do others, I use this one on my 24-70 to control light/movement.
Lee Filters also make something similar but in a Rectangular design that fits into a Filter Holder, but for Video the Circular ND Filter will work better, I think, I'm not much into Video.
Wow, look at that price, haha. But yeah, ND is the only way you'll be able to get wider open on the aperture. I do understand that the shutter speed needs to be at 1/50th sec for 24p You probably won't get the aperture to 1.8 though outside in broad daylight. I'd use it on a different time of day where the sun is at an angle for better control.
