Compare an original video with a transferred video?
I want to compare an original video with the same video but transferred through a device. How can I do that? I want to compare them to improve the transferred video quality.The video is transferred through a device that controls video cameras in operation rooms. It's connected to the monitor through HDMI and so whenever a surgent is doing an endoscopy surgery it'll be shown on the monitor but first transfered from this device.We want to improve the quality of the video if it's not at it's highest quality. To know that, we should compare it with the original video that is directly connected to the monitor.I have some parameters in mind like brightness, contrast, frame rate, blurriness,... and many other parameters that can affect the video quality.How can I measure this?
