1. Smoothness Improvement
Is By Blocks the leasts accurate smoothness option which causes the most artifact and is the least CPU intensive?
Yes. It is easier to CPU to compose new frames by blocks. It is true only without GPU-acceleration. Block artefacts is different. I can't say that they are better or worse. It must be decide personally.
Which of the three offers the best picture quality and gives the least artifacts if configured correctly and CPU is fast enough?
My Opinion: for movies Normal+Shader 13, for anime Normal+Shader 2+Bad Areas Artifacts Mask.
gaunt: By blocks+Shader 11b (It is unreachable from SVP 3.0.6 GUI)
With the smoothness normal option, what are the differences between the selectable SVP-shaders Standard, Simple and Simple Bidirectional. And what are the artifacts of each of those three that can become visible?
SVP-shaders are our know-how. They are based and grown from MFlowFps (MBlockFps) and MFlow functions (see MVTools).
Simple and Simple Bidirectional have maximal sharp frames but less smoothness.
With the smoothness advanced option, what are the differences between the selectable SVP-shaders Original and Complex. And what are the artifacts of each of those three that can become visible?
I don't use advanced smoothness improvement now. But I can say that Complex shader is more complicated than Original. It can give more smoothness in simple scenes and more artifacts in difficult scenes.
About artifacts classification. It is difficult to me to explain it in English. I divide them into 5 categories:
- block artifacts (all SVP-shaders by block). It is like blocking artifact when decoding video with low bitrate.
- waved artifacts (all normal and advanced SVP-shaders). They are best noticeable at objects contours thus are called contour artifacts.
- structure artifacts. They appears on repeated similar objects in screen with wrong motion vectors detected.
- fading and flashes artifacts. It is related to wrong motion vectors detected too. Fixed in SVP 3.1. Coming soon.
- frame-margin artifacts. It is related to wrong motion vectors at the margins. Fixed in SVP 3.1. Coming soon.
- Halo artefacts and flicker (tremor) artifacts are the kinds of waved and block artifacts.
It is only First question and it takes much more than 15 minutes.
