How to Automatically copy keyframe from one object to other with one step

Question

I am struggling about a week figuring out how to do this. For example i have 5 objects, for the object1 I put visibility on 1 frame and invisible on 2 frame. then i need all other objects to have the same keyframes but with the 1 framestep from previous 1-frame we see object 1, 2-frame we see object 2 and further.

ok, here is a python solution:

what you have to do:

Create a collection with the name "Automatic_frame_visibility" and put all your objects in there. After running the script and starting your animation, each object will be visible in the order of the collection with one frame visibility.

python script:

import bpy


def frame_handler(scene, depsgraph):
    counter = 0
 
    for eachObject in list:
        if scene.frame_current - 1 == counter:
            eachObject.hide_render = False
            eachObject.hide_viewport = False
        else:
            eachObject.hide_render = True
            eachObject.hide_viewport = True  
        counter += 1
        
print ("-------- Script started")

bpy.app.handlers.frame_change_pre.clear()
bpy.app.handlers.frame_change_pre.append(frame_handler)


list = []

for eachObject in bpy.data.collections['Automatic_frame_visibility'].objects:
   list.append(eachObject)
