Temporal denoiser for non EXR frames - using a "last 5 files" temporary buffer. Creating scenes with EXRs is just killing my hardrive space.

[JD3D_CGI]

So here's an idea:

I want to render as PNGs because I just want to keep file sizes down,. and sending 50gbs of frames around to clients is a pain in the arse (plus people get scared, confused and angry of EXRs for some reason!)

Is there any way we can do temporal de-noising in the frame-buffer... so say for example, we keep maybe 3 or 5 files cached to for the frame blending... but then they are deleted ad hoc and we just write down whatever file we need?

Not everyone does extensive post work - and I like to get things right "in render".

Also, bonus ideas:

1. Send denoising jobs to backburner easily.
2. PD Player should be able to run a denoising.
3. PD layer to export as frame sequences
