Stock animation
This is a slick and modern motion graphics animation. A tunnel forms from circle particles then explodes to a calmness in the middle before forming back into a tunnel again then the camera travels in as the tunnel then implodes.
Available in 4K UHD with full alpha channel, so you can change the background to whatever you want, add affects such as nice glows and simply import into your editing software and overlay on anything
This is the Blue/Grey colour version but a hi tech glow pre added on a black background, other colours are available with Alpha channel transparent backgrounds, many thanks
