Hi! Just switched from a small NUC as a server to using the emby docker in unRAID. Im using SW tone mapping for some users, the CPU can handle this no problem. I think the bt.2390 is the best option for color accuracy, but noticed that whites (where HDR peaks above 400nits) is VERY blown out. This does not occur with the other options, but they have other flaws, mostly in color saturation or black levels. Is this a common issue for those few using SW tone mapping? @softworkz ffmpeg-transcode-e2c37e90-841f-45fb-a3b5-df5bc9f54967_1.txt

So a question for @softworkz most likely. I've been playing around with ffmpeg with the TM filters trying to get Tone Mapped chapter thumbnails created in the .bif's. I can't seem to use the TM filter in the image extractor in ffmpeg - ffmpeg is reporting that this function cannot use the filter. I have got it 'working' if I simply do a TM conversion to a thumbnail resolution video (to rapidly increase it's conversion speed) and then re-run the thumbnail extract on that to produce the 'SDR/tone mapped' images. Then delete the TM video file. I was hoping to do it all in a single ffmpeg command. It's obviously not urgent - but the 'washed out' thumbnail images on an SDR display are nagging me .. Any thoughts ?
