[HELP] Audio/video out of sync in output

none of them did anything for the halo/ring effect

naturally since, none of them is a dehalo or deringing filter and both are not ghosting.

Also, what is the difference between halo and ring?

Halo: additional outline
Ringing: additional 'specs'

I also tried different combinations of DeHalo and DeRing from the DeHalo/-Ring tab to no avail.

Both dehalo and deringing often does require for the filter to be adjusted to the source, so simply switching between filter combinations might not have much of an effect.
-> can't give any recommendations without a sample that shows the problem

Thank you for your response. I have PM'd you the sample. It's worth noting the halo effect is present in the original lossless footage to begin with.
