About the rule of 180 degrees and achieve film look in the videos?

I'm an amateur and want to learn cinematography.To achieve the film look for a video, a very well known and widely used phenomenon is the rule of 180 degrees. I have found this over and over and across the numerous websites, blogs articles and books.
So taking this as basic rule to be followed, I started shooting videos in 25 fps and 50 shutter speed settings. But one day I was shooting some video outdoors in bright day sunlight. So due to excessive light, using the above settings, the video was extremely over exposed and every thing was looking bright. To correct the exposure, I had to increase the shutter speed up to around 1000th of a second and then the video got correctly exposed.(my ISO was 200 and aperture 3.5 using Nikon D3200)
So now my question is that following such changes in shutter speed, will it affect my video to achieve the film look? This is the breach of 180 degree rule too. What should one do in such circumstances?

Wow.

This 180 degree rule is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene and has NOTHING to do with the shutter speed, lens aperture or frame rate.

When you get overexposed video, you need to stop the lens down to f/11 or f/16. If you had just a basic understanding of the fundamentals of photography, you would have solved that problem in seconds.

If you want to learn the traditional terms used when shooting film or video, I suggest you buy a book called, "The 5 C's of Cinematography"

The shutter speed is determined by the frame rate you pick, so that is fixed, the one reason you need to add a whole lot of light when shooting indoors.

Part of the film look is the shutter speed of 50th, a little motion blur in each frame.
Next time compensate for changes in lighting with your aperture, leaving the shutter speed constant.

Exposure is one aspect of cinematography.

But consider these other aspects…
Lighting - train your eyes to see and recreate good lighting
Composition - study favorite films and art
Coverage - how to use the camera to tell the story
Editing - study editing - good editors often make good directors
