Practical Scenario

Hello everyone,

I am currently having some problems with the DNG files taken with my Mavic Air: every file I try to import in Premiere/lightroom (Still photos, not videos – those work fine) gets marked as damaged/corrupted and doesn’t let me import it. Photoshop and Preview (MacOS) seems to open the file without any problem.

I have all my software up to date but I still can’t use my DNGs (wanted to make a dronelapse with premiere). The problem is both on Windows and MacOS.

Any suggestion to fix the problem?
