    Hi all,

    I am looking for a way to make some HEVC video by my Mac. The target video is like the following example.

    http://demo-uhd3d.com/fiche.php?cat=uhd&id=116

    What I need is 4K HEVC, and in the format of TS. I've tried few different encoding software, but all of them can only export HEVC video in mp4, not TS.

    Is there anyone know how can I produce a video that has exactly the same format as the sample video in the above link?

    I am totally OK if only Windows software can do that. Anyone can help? Million thanks in advance.

    Any particular reason why you need transport stream file? TS is usually used for broadcast transmission systems

    It's because my TV's (LG 84LA9800) build in player can play 4K HEVC file, but only in TS format.

    I have few 4K video's now, and would like to take the benefit of using HEVC. Therefore, I am now looking for a way to do that.

    I've already test my system. The linked video from my original post is HEVC, and it play flawlessly on my TV.

    And I've tried many HEVC MP4 (e.g. Encoded by handbrake), the TV cannot play any of them (simply tell me unsupported).

    Adobe Media Encoder 2015 already supports HEVC (H265) directly. Just choose HEVC from the format dropdown menu. Premiere CC 2015 so one of the few apps/players that can play it back

    That blog says: "this should produce a video file with the file format of .m2t – if you need a .ts/.mts file just rename the suffix" Compressor and probably FCPX can export as a MPEG-2 transport stream (m2t). Perhaps the same method of renaming the .m2t to .ts suffix could be used, dunno about quality, but if you just wanted to watch the video.

    I ran into this problem before and the best solution was to trade in that TV on a better one that can accept H265 in a number of different wrappers. TVs that only support .ts are an example of the rush to the market commercial environment.

    I think, at the moment, you can encode FCP X projects to H265 by first sharing them to a master ProRes file and then bringing that into Adobe's Media Encoder and encoding them to H265. As was noted, Handbrake can do H265 but not currently in the .TS wrapper. They made some improvements in February. You may find AME dog slow on a Mac as H265 really needs a hardware accelerator to provide any kind of performance (not in the chip set Apple uses except for iPhone). Otherwise its CPU intensive and slow. Your TV has a H265 accelerator chip.

    There are numerous technical and licensing problems with H265 and its one of the reasons why H265 isn't that widely available yet.

    If anyone reading this is not a current CC subscriber, note the evaluation version of Premiere and AME do not support HEVC, so there is no way for potential users to test this feature. Once you subscribe for the monthly payment, you get the full-featured version which supports HEVC.

    Thanks for all the info. I will do a bit more reading and pay for it (if I can't test it before I pay).

    Handbrake can do H265, but only in MP4, I need TS, that's the problem.

    Yes, my current plan is exactly export ProRes, and then further encode to H265 TS file by other software.

    Compressor can export TS, but I want H265, not MEPG-2, that's the problem. My TV can play H264 MP4, however, for 4K, I need much higher bandwidth to maintain the quality. And sometimes which cause choppy playback. That's why I want to find out how to make HEVC TS, which can maintain the quality I want at 4K with much lower bandwidth requirement.

    When I ran into this issue a few months ago, the best solution I found was to trade in the TV on a better one, one that could accept H265 in a number of wrappers to push it through the narrow pipe I was using at the time.

    I would like to, but that may cause me an extra $10000 (my current TV is 84", I don't want to go lower). If new hardware is the best solution, I may made a mini high performance PC, so that I can use it for gaming, and playing H265 movies.

    Also, if I upgrade the TV now. I want to go OLED, but it seems the biggest one is just 77" at this moment. And I don't like curve TV.

    But anyway, thanks for the suggestion. Will serious consider if go for new hardware is the best solution.

    In fact, LG have an upgrade kit for the TV. However, the kit only avail in US, Aus, etc, not in Hong Kong. Otherwise I only have to pay few hundreds, then I can have a new build in player that support different format's H265 video. LG keep their promise to provide upgrade path for early 4K adopter, but not in my city. :(

    Googled firmware and found this:

    Not sure if it's any help or if you've already given it a try.

    Cheers

    Thanks for the link. The TV firmware is up to date. However, the upgrade kit I mentioned is a hardware upgrade, which including the HDMI 2.0 update, and the hardware to handle 4K 60Hz single. That's another reason why I want the upgrade kit.

    Of course, LG can release a firmware to let the TV has better support on HEVC, the hardware decoder is there, just how they allow us to use it. If it can decode the HEVC TS file, I am sure it can decode the HEVC MP4 file as well, just the firmware (build in player) not allow me to to that.
