Help needed uncovering more information about video data

[vscav12345]

I have a video that I am trying to get more information about. I believe this video to have been shot on November 10th 2019, but the person in the video claims that the video was made roughly 4 years ago and only just SENT on that November 10th 2019 date by the other party. The file name includes November 10th/11th 2019 (I'm confused why both dates appear in the metadata). I have the EXIF data here below. Based on this information here (resolution etc) what do you believe to be true? Also, I see the date on this data as saying November 11th 2019, but is it possible that it was filmed on a camera in 2016 roughly, possibly edited, then uploaded to a computer and sent to recipients phone. In this case would the file name  change when sent to the recipients phone? Also, regarding the quality of the video, the other party says it was shot on a high quality camera and possibly uploaded and then sent to their phone. I also noticed Track1:HandlerDescription   ISO Media file produced by Google Inc. Does this refer to the producer of the video or the recipient. Please help. This is very important to me.

The filename indicates a date of 2019-11-10 21:46:47, November 10, 2020 at 9:46:47 PM (not sure where you get November 11th).  But that doesn't mean much, as it can be easily renamed from a variety of sources or if it's from a social media site, the date it was uploaded for example.

The System:FileModifyDate, System:FileAccessDate, and System:FileInodeChangeDate timestamps are file system timestamps, part of the underlying OS, and not reliable, especially if the video has been downloaded from the net or copied in some way from the original source.

There's nothing else in the file to indicate the original date.

[vscav12345]

Is there any data to infer what kind of device the video was filmed on ? A phone camera or a regular video camera? Also, the video was not uploaded from a social media site, that I am fairly certain of. If anything it was uploaded to a pc and then sent to the recipient's phone (a Google pixel 3). What about that ISO media Google bit? What is that in reference to? Finally, if it was sent filmed on that November 10th date why isn't the "filmed on" date referenced anywhere in the exif? I appreciate your feedback

The metadata has been basically stripped from this video.  All that is left are the tags necessary to actually play the video.  No additional information at all.  Even the necessary date/time tags are set to zero.  If the video wasn't recoded, there may be some date/time information embedded in the video stream, but ExifTool won't extract this.

If anything it was uploaded to a pc and then sent to the recipient's phone (a Google pixel 3).

Depending how it was sent, that might strip away any personal data.  A lot of apps do this and any app that would have re-compressed it in some way would do so as well

What about that ISO media Google bit? What is that in reference to?

Seems likely that some google related program/app has processed it in some way.

Finally, if it was sent filmed on that November 10th date why isn't the "filmed on" date referenced anywhere in the exif?

(Minor nitpick, EXIF is only one type of metadata.  All EXIF data is metadata but not all metadata is EXIF data.  Video data spec is Quicktime)

It may never have been in the video.  There's no way of knowing.  Programs which make videos are not forced to add timestamps or anything identifiable at all to a video.  And the lazier a programmer is, the less likely it will have any useful data.

Phil, How would I go about capturing the embedded date and time from the video if it wasn't recoded?  Does the fact that all the information was stripped tell you anything as to the nature of the video i.e. if it is a secondary copy uploaded from a pc and then sent?[size=78%] [/size]

Try FFProbe (part of FFMpeg) or MediaInfo.

It says something about the software that (re?)coded the video (ie. apparently Google software), but it is unlikely that you would be able to tell the original source.
