Info on X265 codec

Good morning.

I am a bit confused with the new codecs and I would like to know if the new Bluray UHD use the HEVC or x265 codec, I did not understand the difference between the two formats.

Thanks for the explanations.

H265 is a codec spec. HEVC is another name for it. H265 and HEVC are the same thing.

x265 is the open source free implementation of H265 and is just one way to encode video into H265 for free. There are other H265 encoders. NVidia, for example, has an H265 encoder built into its GPU / drivers called HVENC which is another implementation of H265. Videos encoded by x265, HVENC, or any other H265 encoder are just H265 and any codec that can play back H265 should decode them the same.

UHD Bluray is H265/HEVC. It is encoded by some encoder which is probably not x265.

Video: JVC RS4500 135" screen in pure black room no light, htpc nvidia 1080ti.
Audio: Anthem mrx720 running 7.1.4, McIntosh MC-303, MC-152, B&W 802d3 LR, B&W HTM1D3 center, B&W 805d3 surround, B&W 702S2 rear, B&W 706s2 x 4 shelf mounted for atmos, Infinite Baffle Subs 4x15 fi audio running on behringer ep4000 + 2x12 fi audio mounted in main chair firing into back.

Thanks for the reply.
So the x265 encoding is also used by commercial UHD Blu-ray discs?
