%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%Generates the cropped down version of a video following registration.
%Useful for getting multiple different registrations from the same video
%into the same reference frame
% Inputs:
%     - folder: str of the folder the video is located in
%     - vidname: name of the video
%     - it: iteration of the registration to crop to

% Output:
%     - blank: MxN image displaying which pixels in the original image size
%     the current video was cropped down to
%     - totalmove: Vector of the total pixels cropped for the iteration
%     - video: The cropped video (including the current iteration, which is not typically cropped out)
