"6%" or "8%" mean nothing here
IF "6%" THEN USE "scene change based on SVP's motion vectors"
IF "8%" THEN USE "scene change based on NVOF's motion vectors"
ELSE USE "dumb frame comparison"
Thanks. I've tried various combinations including setting SC=100 (turn off?). 6% is a no go. The issues I saw initially with NVOF motion vectors are amplified by the intro to Hugo which is a torture test for SC. The dumb frame comparison is the only algorithm that works for Hugo and works the best all round.
Bottom line:
- 6% no go any algo.
- SC below 10% with the dumb algo fixes the vertical fast motion artefacts at the expense of smoothness.
- NVOF algo fixes vertical motion artefacts but causes problems elsewhere. Hugo just makes those problems more obvious.
- SVP algo doesn't seem to help much.
- Dumb algo works best overall. Smooth with Hugo and everything with exception of "some" vertical fast motion scenes.
I do used fixed 60 fps though, not "To Screen".
