I'm testing that right now. --rd 5 is "better" than 4, but it's so slow. And on my current live action test sample, it looks like Medium + --rd 5 is more susceptible to reference frames than Slow + --rd 4.
3,4 frames it is more detailed than Slow + 4, but there's more blocking/artifacts. I changed the frames to 4,4 and that helped, though Slow + 4 is still more consistent even at 3,4 frames. (but Medium + rd5 still has more detail).
And now I increased frames to 5,7. I didn't notice that helping Slow + rd4, but it sure looks to have helped the artifacts/blocking of Medium + rd5. Slow + rd4 is still better in that regard, though.
This is with using most of the common(?) settings for more detail. Maybe those detail settings are too much for Medium and rd5 and 23-24 CRF.
Are there differences between presets that can't be changed? Right now, I think I'm basically changing Sub-Pixel Precision to be able to run --rd 5 at a decent speed. Medium, rd 5, Sub-Pixel Precision 2 vs. Slow, rd 4, Sub-Pixel Precision 3.
