I have a null object as a camera controller and as I set keyframes for the z-position, the position movement jerks back and forth without any additional keyframes added. I had to insert this image because it sounds crazy, and I desperately tried looking for this answer almost everywhere - to no avail.
This has never happened before so is it a setting that I'm unaware of?
Thank you in advance.
the position movement jerks back and forth without any additional keyframes added.
This is probably because you got bezier handles in space and this creates this back and forth movement. we call this "The Boomerang Effect".
Solution: click on the two offending keyframes between the movment that is supposed to not change so much and change the spatial interpolation to linear (Ctrl+Alt+K)
BTW it is better for us to see full screenshots and not cropped ones. there are clues that we are missing this way. you have cropped important information.
Thank you Roei for the help and the suggestion of using full screen shots - I was trying to cut down on the size of the attachment.
The video was extremely helpful as well.
