  2. input is HDR, output is SDR, but you missed doing an HDR to SDR conversion. Usually one would do an HDR->SDR conversion using some tone mapping method.

    Thank You Im using DVDfab, I select an MKV SDR fro output and it will take as HDRtoSDR and the colors are just like the bdremux 1080, my question still there, which one of them you like to keep?

  6. HDR changes the way the luminance and colors of videos and images are represented in the signal, and allows brighter and more detailed highlight representation, darker and more-detailed shadows, and a wider array of more intense colors. read: https://en.wikipedia.org/wiki/High-dynamic-range_television

    So, a movie with HDR is better than SDR?

    Only if you have a system that can play it back well.
    Many budget TV's don't do such a great job and in that case the SDR may well be better

    If the PC's or laptop's display isn't capable of processing HDR10, you can try using various software players that do tone-mapping. If you have Windows 11, its Windows Media Player and Movies and TV App can tone-map HDR10. Recent versions of PotPlayer, VLC, and MPC-BE can also tone-map HDR10. (These are just the ones that I have tried. There may be more.)

    Since I descover MPC BE for years I use it, I dont know uderstand why people still using VLC if MPC BE is so simply

    That is too broad of a statement to confirm or deny.
    Just because a movie is HDR or SDR doesn't say anything about its visual quality being better.
    That is as wrong as saying that any movie with a higher bit rate must look better than the same movie with a lower bit rate.
    Neither bit rate nor color space is a definitive quality indicator.
    (Same goes for resolution, some DVDs of movies look better than their Blu-ray releases.)

    Since the MPC-BE has a few bugs - it cannot recognize the default audio track, it has trouble distinguishing Full Range video from Limited Range.

    HDR is basically just a wider color and brightness standard for video (and pictures). SDR is standardized by Rec. 709 and HDR is standardized by Rec. 2020.

    The difference comes through in a wider color gamut for HDR than for SDR. For brightness/luminance, the difference is in their "transfer function", which is difficult to explain and is basically just math.

    Your TV or monitor's ability to display these different colors and brightness levels will depend on the manufacturer, even if it's listed as supporting HDR. You can think of it like a set of speakers - the speakers might be advertised as putting out 20Hz to 20KHz, but do they really?

  16. HDR defines a wider range of colors and brightness than any current TV can display. It then becomes the TV's job to reduce the range to something that it can display, in a way that's best for that TV. So different TVs will look different when displaying HDR video, even when "perfectly" calibrated.

    Try to find the so called pipet function, where you "pick" the white and black points in the footage otherwise you need pro software..
    Davinci Resolve .

    Rec. 2020 is SDR color space
    HDR is Rec 2100, based on Rec 2020

    not sure why people with HD displays go for HDR content then complain.

    Correct, my mistake. 2100 is the HDR addendum to 2020.
