Timeline problem with keyframes.

[Asuki]

I'm reposting this as nobody reached out (this post got buried and skipped?), maybe I'm doing something wrong, or maybe it's an actual problem.

Copy pasting keyframes doesn't work properly, or like before.
As an example If I set keyframes on the timeline at 30 and then I paste the same keyframes on 40 to make the animation not move between 30 and 40, the animation still moves because of micro changes in the "Origin" or "Angle" that shouldn't happen.
Here's a video to understand what I'm trying to say : https://youtu.be/YVmOJoZeETU
Edit -1-
The problem persists with expressions (ofc).
Edit -2-
Another problem, with the expression, shows up only when I apply the wallpaper on the desktop: https://youtu.be/-s64HFnfaC4
The "blink" (created with the "Expressions" new feature) is causing the whole screen to glitch like that, but only when applied on the desktop, it works perfectly fine in the editor.

Hey, sorry, I indeed missed your other thread in the heat of the moment. I will check this out and get back to you.

I assume the published version of the wallpaper does not have the blink expression? Could you share the project file with the glitch visible?

[Asuki]

I left it in the published version with an user properties

[Tim]

Ah, I see, thanks, could you still send me the files though? That would make it much easier to take a look at the root cause. You can mail them to [e-mail].

The problem that I had with the timeline it appears to be the interpolation which by default is different from before:
This is what it used to be: Old default [ibb.co]
New Default[ibb.co]
Is there a way to revert this specific change?

[Tim]

Yeah, like you said, the new default automatic bezier mode is intended to improve "organic" animations and will overshoot values a bit on purpose. We just improved this behavior a bit so maybe you could check it out in the new build we will release today (2.4.79 or newer). You can switch over to the old bezier modes by using the bezier mode button in the timeline editor before copy-pasting, this will apply the bezier mode of the keyframes you copied.

The problem we want to solve is that often -- without adjusting the bezier control points - animations tend to look really robotic. That's why we added this new mode, since it will make it easier for most users to create less robotic movement without manually adjusting the bezier control points.

The oddities with the origin value aren't causing the issue you describe, the values are negligible. It would be better if it wouldn't happen so we will look into it, but it looks like it's just a precision issue when converting from the UI to the real values and back.

Ok thanks for the infos :)
