Animate a Mixamo-rigged character in Blender without keyframes

Moveset recognises the Mixamo skeleton on its own. Import your character, create it as a Moveset character, pick animations and states, and bake them to Actions

Blender viewport with a wooden mannequin and the Moveset sidebar panel — 3D View › Sidebar › Moveset

Step by step

STEP 1Import the character
File › Import › FBX and pick the Mixamo file. The skeleton comes in with the mixamorig: bone names
STEP 2Open the panel
Select the armature, press N in the 3D View and open the Moveset tab. The panel shows Rig: mixamo
STEP 3Create the character
One click. Arm and leg lengths are measured from the rig, so hands land on this model's face, chest and hips
STEP 4Add animations
Open the library and add Walk, Idle and any actions, a pack or a whole character kit. Pick a state: Normal, Brisk, Weary, Cold, Drunk and more
STEP 5Play, tune, bake
Press Play, move the sliders, then Bake. You get ordinary Actions such as walk_weary and wave_cold
