Using the recommended script to dump all metadata:
exiftool -a -u -g1 -ee -api RequestAll=3 360_00HD.mp4 >> Metadata_from_Exiftool.txt
I was not able to get:
Color space : YUV
Chroma subsampling : 4:2:0
Which was gotten from the video player print properties feature.
I attach the two text files showing the metadata.
Where is this information stored in the MP4?

Phil,
Sorry what I sent as TXT attachements is all I know. My knowledge of Exif file structure is zero.

Hi James,
All I can say is that ExifTool should be extracting all available metadata, but does not decode the video stream. My guess is that this information may be in the video.

Hi Phil,
You are wise, yes the YUV data is in the video pipeline according to Wikapedia.
I was able to read it as follows:
REM Probe video pipeline to read YUV
ffprobe -show_streams -i 360_00HD.mp4 >> out_video_pipeleine.txt
Much thanks for your help.
