It seems Homebrew installation scripts are outdated and some sources don't compiled as they should. Hybrid combines a lot of video tools inside but it don't contains pre-installed VapourSynth. It also may require external Script files. It also can be used as a plugin inside other video editing apps, video players and UI wrappers. Users browsing this forum: MSN and 14 guests. So that the good values of the white parameter are not allīunched up at the very high end of the scale.Sun Mar 15, am. V1.14 0 - Make the PQ white parameter somewhat more relative (like HLG), The PQ white level was being limited to 2000 when it should have been 4000. 0 - Slipstreamed a fix into DGHDRtoSDR 1.15. V1.15 3 - Changed to match recent changes to DGIndexNV (see here for more info). Do it beforeĬalling dghdrtosdr() for best performance. Following is a typical script:ĭgsource("hdr sample.dgi",crop_t=276,crop_b=276,resize_w=1920,resize_h=804)Īlternatively, the cropping and resizing can be done in Avisynth. Often the goal is to convert to HD bluray with a size of 1920 x 1080.Īnd sometimes one wants to crop as well. mode="hlg" - Source stream is HDR Hybrid Log Gamma (HLG).mode="pq" - Source stream is HDR Perceptual Quantizer (PQ).impl="0" - Use CUDA on device 0 (use desired device number).impl="255" - Use CUDA, device is chosen automatically.Use fulldepth=true if you intend to a 10-bit encoding. When set to true, 10-bit stored in YUV420P16 is output. This parameter also affects overall brightness so you may have to adjust the light parameter as needed when changing the rolloff. The default value of 0.7 is effective at retaining saturation and contrast. Increase this towards 1.0 to soften and desaturate the result. This value controls a LERP between Reinhard tonemapping and no tonemapping. Reduce this towards 0.0 to smoothly transition to blowout (clipping) of highlights. Values below 1.0 reduce saturation and values above 1.0 increase saturation. Do not overdo it 0.5 to 1.5 is probably the most you can get away with without ruining colors. Saturation adjustment used to desaturate or resaturate blue in the output. Saturation adjustment used to desaturate or resaturate green in the output. Saturation adjustment used to desaturate or resaturate red in the output. Hue adjustment used to correct hue shift.

The default is 0.42, standard for Rec.709. The valid range is 0-1000.įinal gamma for the output. This parameter is relevant only for mode="hlg". Higher values increase the resulting black level. This is an integer (with arbitrary scale) that controls the black level of the output. For mode="hlg", the valid range is 1-10000. Higher values increase the resulting output brightness.įor mode="pq", the valid range for white is 1-2000.

AVISYNTH VAPOURSYNTH SOFTWARE
Use the parameter impl="sw" to run in software mode.
AVISYNTH VAPOURSYNTH DRIVER
If you try to run in CUDA mode without an nVidia card and driver installed, you will get an error. This filter runs on both CUDA and in software mode. The input must be YUV420P16, e.g., from DGSource() with a HDR10 source stream. This AviSynth+/VapourSynth filter converts HDR10 PQ or HLG from UHD blurays to 8-bit SDR YV12 or 10-bit SDR stored in YUV420P16.
