I need help figuring out how to use FMV 1.3.1 with ArcMap 10.4.1 and a DJI Phantom 4 drone. The .mp4 and .mov video files I've created from the drone aren't recognized by the "Add an Archived Video" option. Could this be because they are not MISB compliant and don't contain the required metadata? If so, I'm also having trouble locating the necessary metadata information to use with the Mutiplexer tool. I've read about .srt files with the Phantom 3 that contain such metadata, but I can't find any such files with the Phantom 4 video files. Anyone have insight on this process? Thanks.
