Why animating anchor point leads to curve camera movement?

Why animating anchor point leads to curve camera movement? The same movement animated using position is fine.

Check if the spacial interpolation is set to linear:

It's set to linear.

Your Anchor Point parameter at the very top appears to be in the bottom-right of your frame. If you want it to be in the center then it should be set to [960,540], which is half the width and half the height of the frame. If that is what you want then you need to delete your keyframes, reset the Anchor Point parameter and try again. If it's not what you're looking to do, then please post a screen recording of what the actual movement looks like and describe what you're looking to do instead.

My Anchor point 1920*1080 is in the center of the frame 3840*2160. Look at the video to which I put the link above. The first part: camera moves in a straight line, the second part - along the curve of the line.

Ah, I didn't see the link to the clip, just the image. Now that I click on the link though, it's not loading for me, and I tried in a couple browsers with all extensions and blockers disabled.

It is absolutely free web disk without any ads or viruses. 100% working.

I don't doubt that, I'm just saying that it's not loading for me. My company is likely blocking the site.

Try Tor or Opera with builtin free VPN.

Are all Anchorpoint keyframes set to spatial interpolation > linear. Just select all keyframes.

[Jupers]

All position and anchor point keyframes were set to linear temporal and linear spatial interpolation. Select all doesn't work: there is no spatial for scale.
