Time Displacement by texture...

Hi amazing Blender Community. I have an idea and I found this beautiful video to explain it. youtube.com/watch

This artist uses Time Displacement effect in AE. I have Tried to figure something like this by geometry nodes.

I have imported an image sequence and exported its color as an attribute, to control material shader. as you see i have used a grid as display and used higher number for vertices for better picture resolution.

It is works until I used Scene/Time for controlling image texture frame socket. but when I tried to controlling frame parameters by some ting like index, it turned to red and made error.

If user be able to control frame by random value, noise texture, index or some thing else, then we can make animation time displacement by Geometry Nodes.

Thanks and regards.
