I want to do an animation of the motion of an horse. Now i moved single keyframes because i had some in wrong order. But now they arent evenly spaced, and it shows :)

If somone knows how i could achieve this automatically I would be extremely happy

enter image description here

Helper Script

For each fcurve in the context object's action, space keyframes evenly based on start, end frame and how many keyframes.

import bpy
context = bpy.context
ob = context.object
ad = ob.animation_data
action = ad.action if ad else None

if action:

    fs, fend = action.frame_range
    flength = fend - fs            
    for fc in action.fcurves:            
        N = len(fc.keyframe_points) 
        if N < 2:
            continue
        df = flength / (N - 1)

        for i, kfp in enumerate(fc.keyframe_points):
            kfp.co.x = fs + i * df
