How to achieve feedback loops?

I would like to achieve a video feedback loop type effect and was wondering what’s the most efficient way of doing so?

So far I’ve tried the Frame Feedback, Feedback Blur, and Frame Loop nodes but haven’t been able to achieve the effect I’m looking for.

My goal: https://www.youtube.com/watch?v=dyLRwHvnQBs

Also, see attached image to see the effect I’m trying to create for real-time IMAG.

Any advice on how to create this effect would be much appreciated!
