This probably affects frame type decision, at least that's what I observed when using four lookahead slices compared to just one.

--pmode can have a negative impact in CRF mode, so be warned. I just experienced that.. it produced a lower bitrate than without --pmode at the same settings at CRF 18, and I happened to check a scene with a heavily noisy picture. The dancing of the noise was much uglier than in a test encode without --pmode.

Oh, good tip! That isn't supposed to happen in theory. You should provide a bug report and repro to MultiCoreWare so they can look at this deeper.

It's probably due to the encoder doing deeper analysis as some performance related early skips are avoided. Nevertheless, I got a clip of the scene for my testing toolkit and I can definitely create a ticket for the issue. Maybe there is something there to fix.
