All the functions are explained. What’s not in there are workflows. That’s why there’s a heavy reliance on outside tutorials.
Example of some of the terse information. This is from Conforming Frame Rates
• Floor: The default setting. Final Cut Pro truncates down to the nearest integer during its calculation to match the clip’s frame rate to the project’s frame rate.
• Nearest Neighbor: Final Cut Pro rounds to the nearest integer during its calculation to match the clip’s frame rate to the project’s frame rate. The Nearest Neighbor option reduces artifacts at the expense of visual stuttering. Rendering is required.
There’s no example and only the briefest explanation of what Nearest Neighbor does. Everything is in there though.
