Re-encode UHD
Good day,
my first post, although I follow this thread for a long time now, so first things first:
I'd like to thank you for your work. It's amazing how much effort you put into such a great and free ! solution. Really appriciated!
I'd like to re-encode some UHD material but while I found quite a bit about Quality Tuning, I'm lost when it comes to just re-encoding it, using less bandwidth, but keeping everything else the same.
In particular the HDR Parameters.
Examples:
Color range : Limited
Color primaries : BT.2020
Transfer characteristics : SMPTE ST 2084
Matrix coefficients : BT.2020 non-constant
Mastering display color primaries : R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312680 y=0.329000
Mastering display luminance : min: 0.0050 cd/m2, max: 1000.0000 cd/m2
Maximum Content Light Level : 1000 cd/m2
Maximum Frame-Average Light Level : 96 cd/m2
Color range : Limited
Color primaries : BT.2020
Transfer characteristics : SMPTE ST 2084
Matrix coefficients : BT.2020 non-constant
Mastering display color primaries : R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312700 y=0.329000
Mastering display luminance : min: 0.0000 cd/m2, max: 1000.0000 cd/m2
Color range : Limited
Color primaries : BT.2020
Transfer characteristics : SMPTE ST 2084
Matrix coefficients : BT.2020 non-constant
Mastering display color primaries : R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312680 y=0.329000
Mastering display luminance : min: 0.0050 cd/m2, max: 1000.0000 cd/m2
they all have a bit different Parameters.
How would I re-encode those, while preserving all those values for each file?
I guess there is no "take those Parameters from the source file and re-use them in the target file" Option and I have to provide them manually for every file?
Can you provide an example on how to re-encode an mkv (I use ffmpeg and pipe), maybe with some good tunning tips included?
thanks!!
