Another reason why Camera manufacturers such as Pany will be forced to adopt and release new cameras faster than ever before with the advent of mobiles being able to utilise 4K hvec.

The ITU has approved a new video format that could bring 4k video to future broadband networks, while also making streaming HD video available even on bandwidth-constrained mobile networks. The H.265 standard, also informally known as High Efficiency Video Coding (HEVC), is designed to provide high-quality streaming video, even on low-bandwidth networks

At least I will stop complaining about 4:2:0 :)

@cbrandin Thanks. That really makes sense.

I wonder if 2x anamorphic can work nicely with 4:2:2 subsampling by squeezing more horizontal data.

Interesting. Thanks for the info! I wonder how this all fits with recording media such as SD cards. Re-spec'd, possibly denser, higher cost cards will be required I suppose.

I already posted above, that first it'll be adapted by satellite TV and DVB-C. More by first one. As they have limited resources and always seems to be wanting to put loads of crap on them :-)

4k 4:2:0 would suck...

LOL :-)

@stonebat Right, and regardless of hardware acceleration, more intensive compression produces smaller files at the expense of image quality. H.264 already has 4:2:2 and 4:4:4 profiles that can preserve more color information than AVCHD, but that inevitably requires more data storage. What H.265 offers is the opposite - less data and smaller file sizes without "perceptible" degradation in image quality. But as we've seen with the GH2, what's imperceptible to consumers is far from adequate for even semi-pro purposes.

I don't care about smaller file size. I want same file size with more accurate color information.

Hardware acceleration will catch up. Not this year. Nevertheless this is a good news. One day we'd get GH or something affordable capturing at 4:2:2. Technology advancement going only fast and faster.

H.265, 4:2:2 chroma, DSLM. I'll be a happier camper.

4:2:2 subsampling bandwidth is 2 x 4:2:0 bandwidth. That'd be instant gratification.

Thanks, VK. Do I see references to interlaced frames in the spec? OMG! Do we still need this to be supported?

H.264 isn't being taken full advantage of in the recording space... you can do 4:4:4 intra in H.264. Seeing as hardware support for decoding H.265 will probably come before encoding support, I can see a case where cameras still record H.264 (H.265 is 1/2 to 3 times slower) and H.265 begins to emerge as a delivery codec.

As our world becomes more mobile, it won't matter much if H.265 can be played on a PC... when smartphones, tablets, and TV media players support it, that's when its adoption as a delivery codec will begin to spread.

Right now there is a lot of angst as the major TV piracy groups switch from XviD/AVI (which a lot of people have DVD or media players with support for) to x264/MP4 (which, although technically superior, has less widespread support.)

@karl we definitely need more efficient lossy video coding for streaming purpose.

Users needs and numbers grow faster than network bandwidth, which is not infinite.

@danyyyel Codecs the likes of H.265 are not created "so that manufacturers can continue to sell us something". We (videographers) are not the only users of video codecs. We are even probably very small and minor compared to broadcasters and content delivery services.
