Tonemapping & Videoskalierungsmethode

Hi, i answer in english since this should be your native language.
Tone mappingThe algorithm method used for enhancing UHD high dynamic range (HDR) video to UHD standard dynamic range (SDR) video. Passthrough is not available using Kodi VideoPlayer. Currently Reinhard is the only option until other methods are introduced. This expands the tone curve producing a brighter picture.Tone mapping parameterRaises and lowers luminance based on your display capabilities (NIT Value). Displayed by scale and not actual NIT values. 1.00 is default. Higher or lower value may improve perceived image based on viewing environment and display capabilities.

woran liegt das?

Kodi 19 Alpha - Alpha Versions are dev Versions. That means the have some errors.

welche Methode ist am besten?

Lancos 3 optimiert is the most sharpen. you can use it.

Video scaling methodChanges the size of a video frame in order to match the resolution of the display device. All methods here are non-adaptive so they may produce different amount of aliasing, blurring and edge halos. There are no best methods it’s up to personal taste what method you should use. The methods are:

• Auto - If supported uses Lanczos3 Optimized when video resolution is lower than 720p (1280x720) and video FPS is lower than 30, otherwise it uses Bilinear.
• Bilinear - fairly simple and fast method (video resized with this method may appear slightly smoothed/blurred but with no edge halos also called ringing artifacts).
• Bicubic - more sophisticated method than Bilinear (more precise and slightly sharper video than Bilinear, but can introduce some ringing artifacts).
• Lanczos2 - 4-tap filter that uses a 2-lobe Lanczos windowed sinc function (sharper than Bicubic with less aliasing).
• Spline36 Optimized - 4-tap + 3-lobe filter, more precise than Lanczos2, which tries to produce the sharpest image with slightly less ringing artifacts then Lanczos3 Optimized (differences only noticeable with high resizing factors or when downsizing).
• Lanczos3 Optimized - 4-tap filter that uses a 3-lobe Lanczos windowed sinc function (comparable results to Spline36 Optimized, with less aliasing and more sharpness, but more ringing artifacts).
• Spline36, Lanczos3¹ - 6-tap filters that are more precise variants of above "Optimized" versions (they are sharper but might produce more ringing artifacts in some situations).

Characteristics of different methods:

• Sharpness - Bilinear < Bicubic < Lanczos2 < Spline36 Optim < Lanczos3 Optim < Spline36 < Lanczos3
• Aliasing artifacts - Lanczos3 < Spline36 < Lanczos3 Optim < Spline36 Optim < Lanczos2 < Bicubic < Bilinear
• Ringing artifacts - Bilinear (no ringing) - Bicubic < Lanczos2 < Spline36 Optim < Lanczos3 Optim < Spline36 < Lanczos

Schöne Antwort, aber ich glaub du schreibst über den de-interlacer.
Gefragt wurde nach Tonemapping. Kann ich auch nicht speichern, fällt mir gerade auf.
Beim Tonemapping geht es darum, aus HDR-Inhalten etwas zu machen, dass auch an einem nicht-HDR-Gerät gut aussieht.
