DGPQtoHLG() converts HDR10 PQ to HDR10 HLG. The input and output color spaces are BT.2020 YUV420P16. This filter is intended for use case where full HDR10 HLG is required.

Requirements

• AviSynth+ (x86 and x64)
• Supported color formats: YUV420P16

Syntax and Parameters

DGPQtoHLG (clip, float "light", string "impl")

clip   =

Input clip; must be YUV420P16 colospace.

float  light = 1000.0

Mastering light level (or MaxCLL) of the input PQ stream. If metadata is not available set light as needed for acceptable output.

string  impl = "255"

• impl="sw" - Software mode (slow).
• impl="255" - Use CUDA, device is chosen automatically.
• impl="0" - Use CUDA on device 0 (use desired device number).

Examples

Here is a typical AviSynth+ script:
