System Information
Operating system:
win10
Graphics card:
gtx1050ti

Blender Version
Broken: 2.92 stable, 2.93.0-c4ef90f5a0b1 master
Worked: 2.83 stable, 2.91 stable
Behavior changed in 0e85d701c6

Short description of error
there are 2 error from this issue.
1, the bake action handle bone's rotation as euler, then the bake result are not as expected, in frame 1 to 2 will have a large rotation.
2, change bone or armature's rotation mode from euler to quaternion then bake will cause error (this has still to be reproduced)

Exact steps for others to reproduce the error
1, open file, bones already selected
2,bake the action use visual keying, then the action will have a incorrect rotation in 1-2 frame.
3, change mode from euler to quaternion
4, bake again and will give an error " ValueError: Matrix.to_euler(): invalid euler order 'QUATERNION' ", but this has its own report in #88359

Based on the default startup or an attached .blend file (as simple as possible).
daz_test.blend

from #88378:

** Baking animation just dont work properly in blender 2.92, it give incorrect baking starting at frame 2 ( even if you clean curves and clear parents and constraint). baking works perfectly and smoothly in blender 2.91

#88378 was marked as duplicate of this issue

celpec changed title from ~~bake bone rotation error, and change euler to quaternion then Bake bone action error~~ to bake action result incorrect, and change euler to quaternion then Bake action error

It is always preferable to not have full rigs as example files.
These of course are more complex to debug, please always try to put together a minimal example file:

does this also happen without visual keying?
does it only happen with these kinds of constraints?
...

I can confirm a difference in the bake though:
2.92

2.91

4, bake again and will give an error " ValueError: Matrix.to_euler(): invalid euler order 'QUATERNION' "

havent been able to reproduce this one though

Will see which commit caused this.

So this changed in 0e85d701c6, not sure what is intended here, @dr.sybren would have to comment here.

The quaternion error might be related, but it has also been reported separately in #88359 (Bake of animation keyframes are fail when object is quaternion define but bones is Eular define), will clean up the report description here

Will raise prio, since this might be a regression (looks like one)

Looks like D11282: Fix #88359: Issue of object matrix order use in pose bake fixes this and the quaternion problem. Will let @dr.sybren handle the commit since we're in bcon4 and I'm not sure how all that stuff is handled.

Simple single bone repro file:
T86193_simple.blend

The object euler rotation mode doesn't match the bone's euler rotation mode. When you bake, the discontinuity occurs. If you change the object's rotation mode to match, it's fixed.
