System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2070 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2020-10-27 22:14, hash: 024b65b5e5

Short description of error
When using Bake Action with step of 1 (2, 3 etc) if a curve has a part that isnt moving (where the value holds in say 1 for 10 frames), then it only gets a key on the first one and last keyframe instead of every frame

Exact steps for others to reproduce the error

Insert a key in the default cube.

Create a curve like this (with at least 1 flat area where the value doesnt change)

In the 3d view, go to object > animation > bake action

Result obtained:

Result expected:

Thank you guys!, I understand if it was "intended" as a feature but that breaks the baking and we have the cleanup operators after all if we actually need this.

Let me guess it's running the clean channels operator after baking, should we just make this explicit and have a checkbox to "clean curves" ?
Explicit is better than implicit :)

Yes.

Also yes. but it's not bug technically.

I guess I can confirm if this have negative impact on your workflow and let module decide. It is easy to implement after all.

This is indeed not a bug, but nevertheless it's something that ought to be fixed (see yesterday's meeting notes ).
