It's good to remember that image sensor pixels only have one colour anyway (they are each either G, R or B). 67% of colour information is made up right from the start before your even encode anything. Another reason why 4:2:0 sampling may not be as bad as it sounds.
- Dylan16807 5y agoFor cameras outputting at their max megapixel rating, yes. If you're outputting at a lower resolution or not using a camera then it can be a notable loss of quality. Most web images are probably scaled down, and in other contexts I bet it's similar. If you're looking at a raw camera shot you're usually only dealing with one at a time, so while simplicity is nice the RAM impact of those will be limited.
