Use and converting an asset's frame rates
- A key concept when we're talking about encoding video is frame rate, and frame rate means exactly what it sounds like. It is the rate that frames occur over time in your video. Often this is expressed in frames per second, which is abbreviated as fps. That is the count of how many frames exist in a second of video. Native frame rates include 24 frames per second and 29.97 frames per second. 24 is what is traditionally film, and 29.97 is what runs a lot of American television, so these are some of the standard frame rates that you'll see and where they come from. Now often today we're using these for web videos, but you still see that these traditional frame rates often occur in our list of choices. Keep in mind that reducing frame rates is one way to compress video. If you think about it, if you move down to 20 frames per second or even 15 frames per second from these native frame rates, you're reducing a lot of data in that signal. Now this used to be very common for web video, and…
