Bit depth of the original video #12

Hi, I have a question. As you say，the dataset is extracted from the video of HDR10 standard (10-bit, Rec.2020, PQ) and stored in 16 bit PNG . However, when I read an HDR image with MATLAB, I found that the image contains more than 60000 pixel intensities instead of 1024. This means that this is a real 16 bit image. Is the original video really just 10 bits?

@gzsun1416 Yes, you can use ffmpeg or Mediainfo to check the bit depth of the video. FFmpeg can not extract images in 10-bit format.
