Hello!
Specifications:
Vegas pro ver 22 - 2026
Metainfo v26.05
Voukoder pro (Experiments)
PS! I have AMD Ryzen 7 7840U RAM 64GB / Radeon 780M Graphic 16GB, Windows11 Home 25H2, AMD drivers latest
I use Osmo Bocket 3 10bit HLG (HVEC) video files in Vegas.
Color range : Limited
Color primaries : BT.2020
Transfer characteristics : HLG
Matrix coefficients : BT.2020 non-constant
I want to render a video file from Vegas that would have the same metadata as the original. It would be nice if the final rendering was of the same quality as the original material. For archiving but also for viewing.
At the moment I'm trying an AMD/amf (GPU) HEVC encoder.
No matter how I try, "Transfer characteristics: HLG" is replaced by PQ.
"Matrix coefficients: BT.2020 non-constant" is missing from the metadata at all.
I tried to change the Scene - Video Input params ...
Colors Range - limited,
Color space: Matrix - BT.2020nc, Primaries - BT.2020, Trasfer - ARIB STD B67.
But that didn't change anything. It still turns out that "Transfer characteristics:" are PQ and "Matrix coefficients:" are missing.
In video players, the colors are therefore incorrect.
If I select the same video file in Voukoder Pro Transcoder and render it with the same "Scene", then everything is in place as it should be.
Here's my Scene profile ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::)
