Unable to use videos with express library

I had something simliar happen with some videos I was try to work with, videos that I took with my drone.  Turns out that the metadata associated with the videos was missing / garbled. I bought some image repair tool, and you do two things when using it.  It was  probably due to something silly I did with formating of thechip used in the drone, or the drone software on my phone

I think simliar issues are actually related to the metadata associated with the file in question: metadata is missing, or garbled- making no sense to the software trying to read the file.

You could always take a look at the video metadata and see if it's there, and if it all makes sense- is corrrect. 

To use the data repair utility, this is what I did:
1. You upload a simliar video, that has a correct metadata file. The program uses the information to commpare the broken file to.
2.  Load the "broken" video file.  The program didn't even take 30 seconds to repair the file.  The metadata it fixed was the correct info too, not justcloned from the sample file.  

This is what I purchased- they have a 1 month or a lifetime option, which is what I chose.  I paid $39 for it, but my drone video problem quickly disappeared.
