Millions vs Trillions in 8 bpc
I rendered out a frame of my composition twice for comparison: One as PNG, 8bit and Millions of Colors selected. The other one as PNG, 8bit and Trillions of Colors selected. When i compared the two results, i couldn’t see any visual difference. But Trillions of Colors version is 2 times larger than the other one (in terms of file size). So what is the point of rendering out with 8bits+Trillions of Colors if there will be no difference in visual quality? Why use Trillons of Colors with 8 bit?
The example images i am talking about can be downloaded from below:

There is no point to outputting Trillions of Colors for an 8b project.
Output Trillions of Colors when you want to preserve the color depth in an a 16b project. Output Floating Point when you want to preserve the depth in a 32b project.
If you output at a lower depth than you are working (for example, working 32b float but outputting Millions of Colors), Ae will apply some dithering for you for smooth-looking results. You will preserve the same appearance you had on your monitor, but of course the output depth is lower and overbrights and superblacks are clamped.
