I want to shoot videos for my blog. Nature, landscapes, fitness. Which color space to use in camera while shooting video? RGB or YCbCr?
The question is impossible to answer in a general way.
If a camera offers to record in RGB, it is likely using a completely different codec that could be better or worse. Very few cameras will actually record video in RGB, so if you see the option in a menu, it may be referring to something very particular about the color handling of video on that specific model of camera.
What camera? And what is the exact context of the option?
The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors.
YCbCr is a family of color spaces used as a part of the color image pipeline in video and digital photography systems. Y is the luma component and CB and CR are the blue-difference and red-difference chroma components. YCbCr color spaces are defined by a mathematical coordinate transformation from an associated RGB color space.
So, in my opinion, will better to use the RGB color model. Our eyes do not see the difference between those color systems, but we will save a lot of traffic and space on storage media.
