Psy-RDOQ is typically measured on a scale (default is often 1.0 in x265) and interacts heavily with other settings: psy-rdoq
: Adjusts the selection of encoding modes to favor detail. Where: Psy-RDOQ is typically measured on a scale
While powerful, Psy-RDOq is not a "free lunch." It comes with specific trade-offs that encoders must manage. : If set too high, it can introduce
For movies with heavy grain or dark, textured environments, you may want to push this to psy-rdoq=2.0 to ensure details don't disappear into "black mush".
: If set too high, it can introduce "fake grain," ringing artifacts, or unnecessary noise that doesn't exist in the original source. Recommended Usage Patterns
By retaining high-frequency information (fine details), the overall image feels sharper to the viewer, even if the mathematical error rate is technically higher. Recommended Settings for PSY-RDOQ
