Good question. With all the money we spend on high tech sensing systems it looks like the Navy is using a cheap Chinese drone with a crappy video feed.
Or somebody ran the video through the make it look like VHS filter on their video creation and editing workstation.
The video doesn't break up like compressed digital video does. The artifacts look more like loss of line sync errors.
I would hope our defense industry would provide our sailors with better quality sensing systems than what is shown in the videos.
Try recording a video from MILES AWAY sitting on a vibrating helo. Let us know how it looks.
