    Sure HandBrake can encode with x264's blu-ray specs, and sure you can simply remux the MP4/MKV into a M2TS or a BDMV\STREAM authored structure, or whatnot, and sure it can play.

    And even if you don't get all the blu-ray particulars in, even if you get the PAR slightly wrong, or even the rez wrong, it can STILL play. And blu-ray players over the years have gotten more forgiving, especially when many today can play DivX, Xvid, MP4, MKV, AVCHD, and other non-blu-ray formats as an option.

    I know you're not lying when you say HandBrake's output plays fine on your player. I'm not surprised.

    But that does not mean it's 100% true-to-the-spec blu-ray compatible, and it does not mean just because it plays on your player it will play in all of them.

    Since HandBrake doesn't output raw streams, only MP4/MKV, then you broke blu-ray compatibility. Muxing/demuxing a video stream through MP4/MKV will delete vital data such as IDK, delimiters, HRD, SPS, etc, necessary for 100% blu-ray compatibility, particularly any calculations/data pertinent at the container level.

    Yes, your content plays on blu-ray fine, and works beautifully for you, and it may play on most units, but in theory, sorry my friend, it's not 100% blu-ray compatible.

    But, if it works for you, then fine, go ahead. Who am I to question something that works for you?

    What you said doesn't make sense,if it's 1280x720 or 1920x1080 encoded with 5 r frames and less with a 4.1 profile or less with the proper vbuffs and such it's not blu-ray compliant?Sounds like you are just trying to justify your statement.

    Not at all.

    Blu-ray compatibility is not just at the stream level, but also at the container level - how you mux is also important.

    In short, what I'm saying is that once you put a blu-ray compliant stream into an MP4/MKV you break compatibility because you delete certain metadata vital to blu-ray compliance. MP4/MKV muxers do not manipulate such packets.

    Blu-ray compatible streams need to be encoded a certain way. Yes. But they need to be muxed a certain way too to not delete such info.

    Of course, this does not mean it will not work otherwise. I will bet it will 9/10 times. But I'm talking strictly theoretically here - it may be 90%, but it will not be 100% blu-ray compatible.

    And I don't need to justify my statement when Sonic Scenarist, an industry standard in professional blu-ray authoring, will confirm this by rejecting such streams.

    HandBrake will not produce streams that are blu-ray compliant. You can include all the right elements into HandBrake's "Advanced" tabs, but it will only output MP4/MKV, not something you can work with with blu-ray, like M2TS, or a BD structure, or even a raw stream to be properly muxed.

    This is because much of the blu-ray compatibility is at the container level. Once a video stream, blu-ray compliant or not, goes through MP4/MKV in any remuxing, you broke compatibility.

    HandBrake is still wonderful for lots of other stuff. And it would have been great for blu-ray output, BUT, until it - at the very least - can output raw streams, it will never acheive 100% blu-ray compatibility for its output.

    Having said that, carry on. I personally would use x264 at the command line and properly mux as my method, but I think you're on your way here too.

    UPDATE: Someone mentioned it in another post but I never picked up on it--you have to press "Queue" first in uncrop MKV, then start. That's what the problem is. UncropMKV is working now. Will update with results.

    Thanks.
