Apple phone movies .mov not accepted

Adding to Bob's and John's posts is another suggestion.   "Not compatible" means Premiere Elements can't find what it needs to edit your phone footage. 

The coding and decoding systems (or "CODECS") at the consumer and phone level are labeled "H.264" and the newer "H.265".   Apple likes to use H.265 and calls it "HEVC".   Most Apple computers have it built in and most Windows systems do not.    The H.265 codec is not included with Premiere Elements because it is assumed it should be part of the host system.   John's suggestion to use Mediainfo will show which codec was used by your phone.  

If you use a newer iPhone it comes with HEVC set as a default.  It can be changed to the more common H.264 in the settings system.  The choice will be labeled something like "Most compatible". 

Existing footage can be fixed in at least two ways if changing the file name does not work.  One is to install the "H.265" codec.  It is purchased from the Microsoft Windows store for a dollar.  It is not always easy to install but works once you do.   The other is to convert your existing footage to H.264 using software like the free Handbrake program.   

MOV is a wrapper, what is inside YOUR wrapper - Exactly what is INSIDE the video you are editing?

Does your video use a Variable Frame Rate? See https://community.adobe.com/t5/Premiere-Pro/Variable-frame-rate-video-with-Premiere-Pro/td-p/4601935
If yes, use https://handbrake.fr/ open source transcoder/converter to convert to Constant Frame Rate

Also... is your video h264 or h265?

 Someone said to change all the .mov to .mp4 (Youtube) and it worked for him.  I do not want to do that as I do not know what the ultimate damage, if any, will be.

Make a copy of the mov, change the extension of the copy to mp4, and see if it works.

No harm done.
