Witnessed surreal UFO in Encino, CA. Massive object spinning with vibrant lights. Video evidence available for further investigation.

A few nights ago in Encino, California, I was outside at 4 am, smoking and FaceTiming my friend who lives in the UK. I couldn't help but notice a peculiarly flickering streetlight about two houses away. As I continued to watch it for a couple of minutes, the flickering intensified, and suddenly, it was as if a separate light that was growing stronger and stronger emerged from the original light, as if it had been camouflaged within the flickering itself. The light grew incredibly fast, and I screamed to my friend that it was a UFO. In the blink of an eye, it was right in front of me, only two houses away, either facing me with its top or bottom side. The enormous object appeared to rotate, emitting vibrant flashes of green, red, blue, white, and other colors. It looked surreal, as though it had been plucked straight from a sci-fi movie.
If not for what happened next, I might have doubted my own sanity. Panicking, I tried to record the UFO with my phone, only to realize I couldn't do so while on a FaceTime call. I urgently instructed my friend to check his phone and record the phenomenon. As I aimed my camera at the UFO, he screamed, "What the fuck is that?" and started to frantically ask me what the hell it was. I urged him to record the FaceTime call, and he managed to capture it on video, which I've attached to this post.
As I mentioned earlier, the UFO seemed to spin while emitting a mesmerizing array of colorful lights. It didn't move particularly fast, and it definitely made a relatively loud humming sound, but only when it was really close to me. When it was further away, I couldn't hear it. The experience has left me deeply shaken, and I have so many questions. I firmly believe it merits further investigation by professionals.
Both my friend and I can confirm the events of that night, and we are willing to provide the original recording to any serious organization or journalist interested in examining the footage. The only edit I've made to the video is blurring my name and cutting the part after the UFO disappeared; otherwise, it remains unaltered.
