colour.models.oetf_BlackmagicFilmGeneration5(x: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1], constants: Structure | None = None) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 1]

Apply the Blackmagic Film Generation 5 opto-electronic transfer function (OETF).

Parameters:

• x (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – Linear light value \(x\).

• constants (Structure | None) – Blackmagic Film Generation 5 constants.

Returns:

Encoded value \(y\).

Return type:

numpy.ndarray
