@shuba please read the above message again, this is the instructions. In your videos you are not doing any of these things that I have mentioned.
“Current Value” means the value that is there before you edit it.
In your video you can clearing this value and pasting (-1.3/2) into that value on every keyframe. (ie – you are shifting every keyframe back to -0.65) but you should be subtracting this value from the value that is already in the channel.
Now why can’t you copy and paste? That is because you don’t have any channels to paste to so Blender doesn’t know what you want to do. In the video I explain that I deleted all the keyframes EXCEPT the first frame so “it has channels that it can paste to”.
But when you copy and paste make sure you do it in the VIEWPORT not the Dope Sheet or Timeline.
Also my handle on this site is @waylow, you have been notifying another user that is called “wayne”.
I can imagine that they would be rather confused right now.
