The default is 1.0, passing through the original signal. -pre-gamma-N applies an exponential gamma curve to the input after scaling.Brighter colors will be retained if using tone-mapping. -pre-levels-max sets 1.0 point for input luminance, in either absolute units or as a percentile 0%.-pre-levels-min sets the 0 point for input luminance, in either absolute units or as a percentile 0%.The default is 0, passing through the original signal. -exposure=N adjusts the input signal by the desired number of f-stops up or down.Default is 0.5, which passes through input unchanged. -auto-exposure=N percentile of input signal to average to re-scale input to neutral mid-tone.
#XVID4PSP 7 HDR TO SDR SIMULATOR#
for instance, C:\Users\\Videos\Microsoft Flight Simulator.copy hdrfix.exe and (optionally) watch.bat into a desired directory.oklab for perceptual color modifications.jpegxr for the JPEG XR C libray (and through it, bindgen and cc).time for speed checks in the CLI utility.license: MIT (wrapper and conversion code), BSD (jpegxr library).JPEG XR conversion is done with the jpegxr crate, which wraps Microsoft's BSD-licensed JPEG XR codec.Īlso works with 16-bit float input as saved from the Windows Game Bar now, however this is less tested. There are a few parameters for adjusting the conversion. Outputs files as regular SDR (standard dynamic range) PNGs in bog-standard sRGB colorspace.
This is a tool I wrote for my personal usage dealing with HDR (high dynamic range) screenshots of Microsoft Flight Simulator, as taken with Nvidia's GeForce Experience game overlay capture utility which saves a JPEG XR in 32-bit float precision scRGB, and an 8-bit-per-channel PNG with lower resolution information, but encoded with BT.2100 color space and transfer function.
