I have video of the craft and I don’t know how to share this with the correct agency

A white helicopter was flying around (a military helicopter from what I have researched) I looked up and I thought I saw two silver balloons in the sky but realised these were not balloons. The helicopter was flying under where they were and they were moving parallel to each other so I grabbed my phone and filmed them, after reviewing the footage (it’s only 14 seconds long as my roof was in the way) I slowed down the shot to find a 3rd craft. Blink and you miss it. It’s so fast it’s not visible unless you slow the video down. It’s moving as fast as the speed of light. I feel this video is a really important piece of footage. And I want to send it to any one who can either explain that what I have seen is “nothing” or tell me that these 3 craft are unexplainable. I have never seen anything like this in my 35 years of living. And I just want to send this to the relevant agency but looking online I can’t find it/them. I will upload the video from my phone. You need to scroll in to see them in the sky. I’ll upload the video original video and then one I have screen shot myself of my own video where the third one comes in and flys so fast. I have managed to slow it down to see. I would really appreciate if you could let me know what I’ve seen. Kind regards Phoebe
