10-bit HEVC for HDR only?

Post by lone_tree » Thu Nov 23, 2017 12:57 am

Quick question (I hope). Is 10-bit HEVC primarily for HDR content?

Is there any reason I would encode my Blu-ray titles with 10-bit HEVC? (I assume no, since they're mostly AVC or MPEG2 on disc and probably don't support 10-bit color.)

Handbrake does not currently do HDR, so the answer is "no".

Well, 10-bit (be it HEVC or H.264) can help a bit with some types of artifacts at low bitrates, due to the higher internal precision of the encoder. That's the only advantage you'll get encoding 10-bit through HandBrake.

Thanks for the reply. I guess a similar answer would be in order for 12-bit. Are there any set top players (Roku, ATV, etc.) that handle anything above 8-bit? (I should note that I don't have any HDR titles so that's not my point in asking.)

10-bit is largely for epeen and testing.

Almost all devices with a HEVC hardware decoder out there supports 10bit, so probably your devices can already play it. Most H.264 hardware decoders can't decode 10bit.
