From the youtube comments: Two different cameras at two different frame rates, both at 180* shutter angle. The main camera was at 24fps and the "high speed" was only 120fps. You've got a very long exposure with the slower camera, less chance to miss the muzzle flash and it's bled over one big frame. The muzzle flash was simply between frames on the high speed. You can find the same thing happening on videos all over, including our other testing videos on ballistic clay and gelatin Raw straight out of the camera in 4K with no cuts: https://www.youtube.com/watch?v=-bShWhdzEZ8 https://www.youtube.com/watch?v=-bShWhdzEZ8 The damage: https://youtu.be/f_Y8rXMb1qs https://youtu.be/f_Y8rXMb1qs Brighter and slower slow-mo here: https://www.youtube.com/watch?v=JkpWJuSvd7A https://www.youtube.com/watch?v=JkpWJuSvd7A Show less
