Samurai Blade and 1D Mark IV
 

I'm thinking of getting these as a field monitor for my BMPCC so I can offload files more easily but would also like to use it with my 1D Mark IV. Atomos said it would be a higher quality video since it's not being compressed in-camera. Anybody know about this? I'm not quite understanding the technology behind it as much as I'd like so I'm reading. I was hoping someone here with more knowledge could give me a dummy version of how it works.
