Anyone know how to edit position keyframe speed from remains the same to increase or decrease (from A to B postion).
For example: in this video, at 11:54, how to do this in Final Cut Pro X? Thanks a lot. ,

Afaik (but I'd be glad to be corrected) there is no way to make bezier keyframe paths with the transform tools. If the purpose is an ease-out, you may use Ken Burns instead of crop - I think the behavior is built in there - at least it looks quite organic.
Before the absence of a precision keyframe editor bugs you, try Ken Burns. At least it's easier.

The last resort would be Motion. Though there is still no send to Motion command, and the free online XML-converter that spat out a .motn-project seemed to stop working recently, you could still manually import the source clips there. A hassle? I agree.

All of this is possible in FCPX. As for ease in/out, in FCPX it's called Smooth.

First, I want to point out that this is why my crew always shoots 4K. We edit in 1080 Project timelines, but I can take one camera in an interview with three people, one wide shot, and make it look like three or four different cameras were used. But if you are shooting 1080, depending on the clarity and quality of your video, you should be able to zoom in 130-140 (I've gotten away with 150 on occasion) and I'd never use those black bars to fake anything.

So, how do you ease in/out keyframes in FCPX? Turn on the Viewer OSC so you see the movement overlays when you keyframe. To do this click the control in the bottom left of the Viewer pane.

Then right-click a keyframe diamond/position to change that point from Linear to Smooth (Bezier). Then you will see the handle to control the ease. You can curve it by pulling the handle up/down or increase/decrease the speed of the ease in/out by pulling the handle closer or further from the keyframe diamond.

Below I've keyframed the X position to pan the image across the screen. The original is a wide shot of two people at a table. I want to pan a CU from the person on the right to the person on the left. Original clip is 4K placed in 1080 Project, Spacial Conform = 0, Scale = 100%.

I've keyframed the pan and added an ease-out of the pan, and a slight dip in the pan. I did it all inside the Viewer and never had to touch the Inspector or any other controls. Very fast, very easy, very intuitive (once you know the control is there).

I love how the guy in the tutorial calls letterboxng "cinematic bars". Please. Just no.

Anyway you can bezier or smooth many things in FCP but not everything. For Rotation, smoothing cannot be turned off. For Scaling, smoothing cannot be turned on. You can get around the scaling issue by using the Ken Burns cropping effect, right clicking and choosing one of the Ease options. Just know that "Ease Out" is for the beginning of the movement and "Ease In" is for the end of the movement.
