Hello Selur,
It seems that to convert Dolby Vision to SDR in Hybrid there is available only the Vapoursynth filter "ToneMap (Placebo)"
I noted that this filter is very slow, especially in "preview" and in the initial encoding,
This filter should support the GPU, but in input I don't see any option to enable the GPU for this filter.
Do you know if this filter is able to use the GPU ?
As additional observation, if one as defined in "Video Usability Information" to propagate the matrix, transfer, primes from input to output.
In case of conversion these values will be wrong and this option should be disabled.
