Here's the original video source (2m27s) https://www.youtube.com/watch?v=GdYc03L_gZ8
I chopped the video up myself only to the good parts

The channel's owner recorded the video themselves. They posted an edited version of this video with music added before this one, and in the description they said: "filmed black triangle ufo hovering over san diego neighborhood on June 13, 2010. used sony trv-99 camcorder... sorry, no tripod. ufo hovered for 5 minutes, in complete silence, then disappeared. they're here." and in the comments they said they watched it silently hover for a couple of minutes before getting the camera.

The footage is also discussed in this forum https://www.abovetopsecret.com/forum/thread602439/pg1

also, i just realized that the first edited video they posted is higher quality, which would be this one (I don't understand why they had to add that stupid music) https://www.youtube.com/watch?v=YpcTT0XbUDA
