Hi Gareth Thomas @AMD, and thanks for your reply. It's a refreshing change to have actual contact to an AMD dev! :) I wish I had this luxury for other...

Thank you. Supporting 8bit would be a nice improvement for my users.

fansubbers need perfect color matching for some of their effects to work properly. There's no standard for HDR to SDR conversion. So after tone mapping, every video renderer and CE...

I'm never opposed to increasing color precision, but how would it help in this specific case? As I said, everybody does HDR to SDR conversion differently. It's not an issue...

@astiob, thanks for the nice welcome! Let me try to explain the color matching problem. Probably most of what I'll explain you already know. But it doesn't harm to recapture...

Just to clarify: If you say "sRGB subtitles", do you mean subtitles that the subtitle author originally created for an SDR video? Or do you also mean subtitles that were...

Ah yes, you're right. Ok, let me think through a couple possible scenarios that come to my mind: Content options: A) BT.2020 HDR UHD Blu-Ray. B) BT.709 SDR Blu-Ray. C)...

Good points. You're right that due to the difference between relative and absolute transfer function, we can't ever get mixed HDR/SDR combinations perfect. However, it's not that hard to produce...

P.S: Just to clarify: I believe most pixels in a subtitle are either totally opaque or totally transparent. For both of these it doesn't matter if we blend in linear...

@rcombs, fully agreed! @astiob, fair enough. I've never even thought about blending in linear vs compressed RGB making a noticeable difference. I'm not completely sure what we could do about...
