Looks like old cheap camera exhibiting massive smear from cmos overload (verticle lines) as well as a very slow frame rate, and slow electronic “shutter”. I think the mysterious horizontal flying bars are fire flies. But its shot in January, so I dunno...
The project has been filming virtually continuously for two years so if it’s fireflies they should have seen them almost every night in season. Also, some of the bars disappear behind the distant ridge so they can’t be close. I don’t know what these are but my nighttime surveillance cameras don’t show anything similar. My cameras do show close “orbs” but those are obviously insects reflecting out of focus IR back.
The only time I have ever seen fireflies in person was when visiting my grandparents in Iowa almost 60 years ago; we don’t have them here in the PNW.
