Filter suggestion

[dave_scream]

This is why most folks typically at least use some mild degrain, deblocking, artifact removal filters during re-compression unless one is encoding lossless.

Can you please share some basic settings for Hybrid's (Vapoursync?)  universal(light) DeGrain+Denoise+Deband(for reencoding) filter settings?

Maybe share profile?

There is too many different filters and for newbie it is very hard to find light and still fast solution

Since I think it's a bad way to revive a 4 year old thread and send it into another direction I split your post into a new thread.

About your question:

Since:
a. sources are different (different type of grain, amount of detail, etc.)
b. quality perception is different
it does not make any sense to suggest any filtering.
A filter with setting X which might be good for user A with source B might be bad for user A with source C or user D with source E.

If your main goal is for better compression while keeping details you should probably only look at some DeGrain filters and deblockers.
Some folks like Deblock_QED and SMDeGrain, but like I wrote depending on the source using them might be a mistake.

A general suggestion I can give you when trying to understand what filters are best for you goal is to:
a. enabled 'Filtering->Filter view'
b. enable 'Filtering->Vapoursynth->Misc->Split View' and especially look at the 'FilterView Plaement' 'interleaved' and 'difference'. Those help to spot the effect of filtering.
