From the Settings Sticky

Quality_prec
Also known as Image quality Priority in CCE 2.5 and Quantizer characteristics in CCE 2.66 +. This setting ranges from 0-64, but is scaled for CCE 2.5 which uses a 0-100 scale.
This setting controls whether CCE gives priority to the fine details of the image, or evenly colored flat areas. A low setting will give priority to details, but could result in blockiness or color banding. A high setting will favor flat areas, but could result in edge artifacts.

So you don't have to worry about converting it for 2.5.
I find the default setting is good for most movies. Of course it depends on the type of video, the bitrate, and who's watching it. If your bitrate is high enough you shouldn't have to worry about it. When it get's too low for a perticular source it really becomes a choice of which type of artifact do you hate most: mostquito noise or blocking/banding? Before it get's to that point I usually try light filtering though.
