Do you mean something that will link a specific coordinate to a specific frame in the video? I don't believe that there's ever been any data point to do that.
"It didn't work" isn't helpful. What was the exact command used and the output.
Read FAQ #3 and use that cmd
Please use the Code button for exiftool output

Please include your OS/Exiftool version/filetype

You would have to use some timestamp to associate the metadata with a specific video frame.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Hi,
I look at frame id because, my software uses opencv to get image from mp4 and in this case the only ID I can have is frame ID, there is no way t get a timestamp coming form underlying API.

It seems as if I'm stating the obvious here, but if you know the frame ID and the frame rate, then you know the time since the start of the video.

I can't be more specific without knowing what device we're talking about.
