Inverting Pose Bone Matrix (reset), then assigning matrix back with new position, rotation, etc.

AN Node to keyframe every pose bone, you will need this one day, I guarantee...

INPUT boolean "record" object "armature"

Ensure your bone armature is "clear parent" so they can move and also you need to use Euler Rotation (it depends).

import bpy

if record:
    for p_bone in object.pose.bones:
        p_bone.keyframe_insert("rotation_euler", frame = bpy.context.scene.frame_current)
        p_bone.keyframe_insert("location", frame = bpy.context.scene.frame_current)

Ensure you clear parent armature and also set rotate euler... there might be case when bone might wiggle because of gimbal (?)
