I have been having this issue with my Mavic 2 Pro where I download the videos to my pc to put in my video editor ( DaVinci Resolve 17) and when I add them to DaVinci it says video offline. It has happened twice and the first time it happened I went into the camera settings on my M2P and reset to default then made my changes I use for shooting. After I did that the videos worked fine. Now it has happened a second time. Just wondering if anyone else has experienced this.
