Encoding HDR

Post by db1964 » Fri Jun 01, 2018 12:33 pm

Alright this may be a dumb question but , I going to take a risk and ask it anyway.

It's impossible to read a review of 4K TV's these days without also reading about HDR and all the different flavour variants thereof ( HDR10, 10+, HLG etc ). If I were to encode a 4K Bluray which included these details ( is that the right way of putting it ? ) would they be included in the mkv file ??

No, HandBrake doesn't do HDR at this point, sorry.

Is Handbrake handling of greater than 8 bits on the horizon or a long way off? Now that ripping of 4K Blu-ray discs is possible, it will become a much more requested feature!

It's at least some way off, I'd say. No idea how long though, if I'm being honest.

Hello there, just for clarifying the situation!
I am trying to compress (in mp4 or mkv container) a 4K video with HDR10 h.265 profile standard.

Is HandBrake able to do that?
I tested the simple h.265 profile with INFUSE software on iOS and it is not able to play it.
VLC on PC or Mac has no issue.
Will I have to use "h.265 10bit" video settings in order to maintain the HDR10 profile?

Thanks! 8)

You can't maintain HDR with HandBrake.

Understand! Is there a technical reason?
Will HB support this profile in your opinion?

Thanks!

Yes, no one has done the work to support it.

Yes, many of our filters don't support working on HDR, so everything is converted to standard dynamic range 8-bit 4:2:0 internally -- there is no way to recover the lost information then.

Ok,
I finished my test!
I bought an original blue-ray 4k HDR. I transcoded it with h.265 10bit profile 16k mbps.
Original mkv was 52GB and after HandBrake it's 11GB mp4.

The result is great, fully compatible with INFUSE & PLEX apps & VLC (Win10, Mac, Ubuntu, iOS, tvOS & Android).
Also macOS quick time can play it!

Really hope that HDR will be supported soon! :wink:

I can find the answer, but 6 months old!
So is there any updates?! This is what I mean!
