    H265 would half that time with same quality.

    It is wrong statement. Check our H.265 topic, Netflix tests showed that 50% advantage is true only if you use extreme very slow modes. And they tested it almost only for 24fps content (prediction accuracy and ability to use different larger and smaller blocks are much more important). For 60fps content and fast encoding difference is more like 10-25%.

    Well my content is 25p (Australia) so it would still be a much smaller file for same quality. I don't have NBN yet, if so it would be non-issue. I'm sure a nice Muti-core machine (yes, no GPU) could easily spit out good H265 fast.

    @alcomposer

    Just understand that you need. If you are using youtube and have good channel, must smarter is to use hardware encode and higher bitrate. Saves time and electricity bills. As I understand youtube won't accept HEVC soon as otherwise they need to obtain huge number of licenses.

    Yes YouTube is waiting for new 'less expensive' patent HEVC replacement... or maybe force HEVC to reduce cost of licences.

    You must have nice fast internet @Vitaliy_Kiselev! :-)

    President Kazuo Ushida, Nikon's biggest camera celebrating its 100th anniversary in July, responded to the interview of the Asahi Newspaper and showed a policy of shifting its pedestrian position with the health care business as a new growth field. While the sale of core digital cameras has been dropped by smartphones, we began cutting down on our hands with the US-based companies in the ophthalmology camera business. Digital cameras are developing a product that supports high-definition "8K", a strategy to differentiate them from smartphones.

    On the other hand, digital cameras focus on high-end models, narrowing down models, and planning to differentiate themselves from smartphones by "absolutely enhancing image quality" (President Ushida). We are aiming to commercialize a camera with resolving power that can withstand 8K compatible large screen televisions, which electric machinery manufacturers rush to develop. It is said to develop high performance lenses and sensors corresponding to 8K.

    Sharp and Samsung lead the pack

    Sharp has been a strong advocate of 8K LCD TVs, and claimed recently that its worldwide sales of 8K models so far in 2018 have exceeded its target. They want to begin to deliver 8K video programs in December 2018, said the sources, adding that the advent of the Tokyo Olympics 2020 should also help boost sentiment for 8K TVs.

    Foxconn's 10.5G line in Guangzhou is expected to kick off volume production of 8K TV panels in 2019, which will help Sharp bring down 8K TV production cost and ramp up sales in China.

    Samsung will begin marketing its 8K QLED TVs at the end of August when it unveils its 8K line up at IFA 2018 to be held in Berlin from August 31-September 5, according to a Korea-based ET News report.
