I made some keyframes for this null object's position. Later on, I had to increase the composition length. Now, I want to split all the keyframes I made for the null object's position so that they're divided equally on the timeline. I don't want to manually do it, please help
I don't know what you mean by "split". Do you mean that you want to expand or stretch the keyframes so that the same number of keyframes fills a longer duration? If so, see this section of After Effects Help.
Yeah, I wanted to expand them along the timeline. Didn't mean split lol
