0.91.8发布
No bug fixes, just a "quick" algorithm update.
In older versions, NGU Sharp was optimized for movies that were downscaled using gamma light. A studio insider told me that some studios use gamma light and some linear light for downscaling. So starting with v0.91.8, all NGU algorithms now try to hit middle ground between linear and gamma light. Which means we won't ever get "perfect" results, but with the old version the interpolation error was sometimes big and sometimes non-existant. With the new version there will always be an error, but it will always be relatively small.
In all older madVR versions, "direct quadrupling" was identical for "low" and "medium" settings. So there were really only 3 different performance vs quality settings. I've now rectified that: The previous low+medium settings are now low. The previous high setting is now medium. And the previous very high settings is now high. Finally, I added a true (and slower) new "very high" setting. This is all for direct quadrupling. Doubling is unchanged.
Now I need your FEEDBACK, once again:
1) Do you like the new "NGU Standard" and "NGU Soft" variants? Personally, I like "NGU Standard" a lot. But I think "NGU Soft" is too soft to be useful, and I'd like to remove it again. But since I spent a lot of time creating it, I thought I'd let you test it, at least.
2) Does "NGU Standard" work better for (non-aliased) low quality content now? Or do we still have to use NGU AA for that? Ideally I hope that we can now use "NGU Sharp" for high quality soures, "NGU Standard" for low quality (but aliasing free) sources, and "NGU AntiAlias" only for aliased sources. Is that reasonable? Or is "NGU AA" still the best option for any low quality sources, aliasing free or not?
3) I want to remove the "Soften Edges" option, because "NGU Standard" was made to replace it. Any objections?
4) With all the changes in this build, I feel that "double twice" is no longer needed. "direct quadrupling" should now always be identical or superior in quality and much faster. So I would like to remove "double twice". Any objections?
