When I put a keyframe, my focal length changes by 45 mm. And then when I try to change it, it does not change. I attach the video.

Go to Scene Settings
Press the Color Picker icon under the Ambient Color indicator bar.
Hi.
When you activate "Pro Cam" you are wearing fixed lenses (as is done in the cinema). It makes no sense to create an animation for the change of a fixed lens because in reality you cannot change the lens in the middle of a movement. What you can do is disable Pro Cam and animate the Zoom which is as if you had a Zoom lens. If you have not updated the program, I recommend you upgrade to version 4.6.13
Thanks!!!!
