I just noticed that an image I downloaded from the internet cannot be edited as my other photos on my phone (applying filters, adjusting brightness, etc.). I'm thinking this might be because the way the downloaded image is encoded doesn't support channel separation like the example above...(Or maybe a problem with permission? Idk :)

Is there a reason why we choose the "blue-yellow" deviation and the "red-cyan" deviation from grey in this color model? IIRC, human eyes are more sensitive to the light frequencies around the green color, so why not give more space to green in this color model?

This is new to me. At first glance I thought it was similar to CMYK in printing industry but it's entirely different. Any particular reason why videos require different color schemes than pictures?
