Just for the record, at 6 the "worms" will be no more than light
edges on vertical lines, there will be no trailing effects.
If the source has bad ringing, the light edges may be preferred
to carrying nasty ringing over into the encode. At 5 no light
edge should be produced. You can of course use 6:6:5 safely.

Please experiment on your own. It should take you only a few
minutes to find good values.
