Join Richard Harrington for an in-depth discussion in this video Bit depth for video, part of Motion Graphics for Video Editors: Terms and Technology (2014).
- Bit depth is essentially how much information…is described by the color data inside of an image.…You might have heard of the expression 8-bit or 16-bit.…Well, this is easy to misunderstand.…Many early video games were 8-bits of detail, total.…And the same can be said for GIFs…that are often used on the web.…However, when we're talking about video graphics…and we say 8-bit graphics, we're referring…to 8 bits per channel.…Essentially, 8 bits is 2 to the 8th power.…
So if you took 2 and multiplied it by itself 8 times,…you get a value of 256, let me show you.…I'm going to open up an 8-bit image here…and if I take a look at the levels adjustments…for just a second, Image, Adjustments, Levels,…you'll see that it ranges from 0 to 255.…Well, that's 256 levels of detail, or 2 to the 8th power.…And that level of detail exists in the Red Channel,…the Green Channel and the Blue Channel.…
If you take 256 possible values for the red channel…and combine them with 256 possible values…for both the green and the blue,…you get a high value of over 16 million colors.…
