All animation systems STILL broken on Speed-Ramped clips (2024, and 2023 and earlier)

[bmartin219]

This is happening in 2023 (23.1.0) and 2024 (24.1.0 and 24.5.0). I have a M1 Max Macbook Pro 16" 2021.

Step 1: Select any clip that has time remapping on it (keyframes that animate a speed ramp).

Step 2: Go to the clip's motion settings, animate scale from 100 to 50. Or position to move in any direction.

Result: The clip will either go black (2023), or it will remain static at the final keyframes value, instead of doing the animation to end on it.

What should happen: The clip animates scale and position normally.

This has been a problem in Premiere for years and years - and it sill hasn't been fixed?

I have all three working, speed-ramp, position, scale.

The easiest way is to animate speed ramp on the timeline instead of the ECP.

Nest between Position keyframes and time remapping keyframes.

So, I do realize you can nest between these to get them to work right. I guess my question is, is why is it necessery? That is still a workaround, and this problem has persisted for over 6 years.

There's two processing chains of complex calculations involved there. Nesting prevents mixups.

Which is why it is useful anytime you do multiple complex operations on a clip.
