So I'm finding a weird thing iwth the latest version of Premiere Pro 2020 on Windows.  Encoding:

 

HEVC (H.265)

Match Source

Software Encoding

Profile: Main 10

Level: 6.2

Tier: High

Check Rec 2020 Color Primaries

Check High Dynamic Range

Check Include HDR10 Metadata

Color primaries: Rec2020

Luminance Min: 0.005

Liminance Max: 4000

Constant Light Levels Maximum: 4000

Constant Light Levels Average: 1166

CBR encoded

 

OK so that's the settings for both encodes.  One is the full hour and a half movie that returns in MediaInfo:

Go back to Media Encoder and use the same settings just reset the project and encode a brief duration.  This returns in MediaInfo:

 So you will see on the short one there is HDR_Format info where the other there isn't.  Also the short one has all the light level and liminance info but the long one doesn't.  Identical encodes.  Even the same source, just the duration encoded is different.  Anyone know what's going on?

As none of us are engineers, I doubt it.

 

@franciscrossman-J6rJng or @TrentHappel  ... either of you available?

What's interesting to note is if I do:

 

Z:\ffmpeg>bin\ffprobe.exe -hide_banner -loglevel warning -select_streams v -print_format json -show_frames -read_intervals "%+#1" -show_entries "frame=color_space,color_primaries,color_transfer,side_data_list,pix_fmt" -i movie.mp4 I get:

{
    "frames": [
        {
            "pix_fmt": "yuv420p10le",
            "color_space": "bt2020nc",
            "color_primaries": "bt2020",
            "color_transfer": "smpte2084",
            "side_data_list": [
                {
                    "side_data_type": "Mastering display metadata",
                    "red_x": "35400/50000",
                    "red_y": "14599/50000",
                    "green_x": "8500/50000",
                    "green_y": "39849/50000",
                    "blue_x": "6549/50000",
                    "blue_y": "2300/50000",
                    "white_point_x": "15635/50000",
                    "white_point_y": "16449/50000",
                    "min_luminance": "50/10000",
                    "max_luminance": "40000000/10000"
                },
                {
                    "side_data_type": "Content light level metadata",
                    "max_content": 4000,
                    "max_average": 1166
                }
            ]
        }
    ]
}

So oddly it's there, but for some reason on the bigger mp4 file it doesn't show thru MediaInfo.  Not sure If I'm the only one with this issue.
