Viewerframe Mode Extra Quality -

| Setting | Behavior | |---------|----------| | Viewerframe Mode ON, Extra Quality OFF | Fast, blocky, lower-accuracy preview – good for layout or blocking. | | Viewerframe Mode ON, Extra Quality ON | Slower but pixel-accurate preview of the final look – great for material fine-tuning or before a final render. | | Viewerframe Mode OFF, Extra Quality ON | Full-scene, high-quality but potentially too slow for interactive work. |

| Feature | "Extra Quality" Mode | Standard/Low Quality Mode | |---------|----------------------|----------------------------| | Deblocking filter | On (strong) | Off or weak | | Chroma subsampling | 4:4:4 (full) | 4:2:0 (compressed) | | Scaling algorithm | Lanczos or Spline36 | Bilinear or Nearest Neighbor | | Dithering | Enabled | Disabled | | Frame dropping | Never | Allowed to keep sync | | Render latency | Higher (2-3 frames) | Low (0-1 frame) |

Colorists live and die by viewerframe quality. If your viewerframe crushes blacks or clips whites due to a "Preview" rendering path, you will make bad artistic decisions. Extra Quality mode provides true scoping accuracy.

"Extra Quality" is a beast. It is not for casual use on a laptop from five years ago.

The Rule of Thumb: Use Extra Quality only for scrutinizing specific frames (stop-motion analysis, color grading checkpoints). For general editing or timeline assembly, use a lower mode and toggle Extra Quality on occasionally for verification.
