I am using metadata (attached) along with some aerial drone video. The speed I am using is in mph and the altitude is in meters. I am not sure if I should change speed to km/h to keep the SI units consistent. This is probably not the reason for my issue though. If I had to wager, I would guess that maybe some of my values in the metadata are not conforming to MISB standards, but I have looked through multiple times and can't find any discrepancies. Also, it is not a software problem since I have been able to successfully get a video footprint with the FMV tutorial video and metadata. The lat and lon of the video is correct but there is no footprint (see image below). I have tried multiplexing other videos with similar metadata set ups and have been unsuccessful thus far. I would appreciate any assistance. Thank you.
