The Cavern

The Cavern is the closest video we have to a scuba diving video screensaver. The cavernous setting reveals an underwater world which you would expect was filmed by a scuba diver- it wasn’t. Instead we found this amazing fish tank at one of the world’s best aquariums. You can view the full promo clip below and we recommend selecting 2160 4K from the cog icon after pressing play, then the full screen button next to it. The promo clip doesn’t have surround sound, but the downloadable MP4 videos are mastered with 5.1 surround sound.

If you are looking for a 4K underwater video with beautiful fish for your TV or computer screen, The Cavern is a great choice. This underwater setting is filled with marine fish in a wonderful range of colors. The scene is quite mysterious with light at the end of a tunnel, perhaps made by falling rocks or large bricks from a bridge?

Every now and then you will spot a strange mist at the end of the tunnel. This is an ingenious way of adding oxygen to the big tank. Usually this is done in a more subtle way with a line of bubbles often hidden in a corner. However in The Cavern the aquarium designers have added to the feeling that we are in some kind of ruins by blasting air in to mimic the effect of a bomb blast or an explosion.

As with all our latest 4K aquarium TV wallpapers, the audio is 5.1 surround sound. In this case we have used a very relaxing underwater soundtrack with gentle bubbles. This allows you to use The Cavern as a relaxing background video, just glancing at the screen occasionally to watch the many fish. There must be over a hundred fish in this impressive fish tank. It is very watchable for longer periods of time compared to our smaller fish tanks- there is just so much going on and the fish are enchantingly colorful.

Besides the 20 minute 4K UHD video, you can also choose a Full HD version. This more affordable option is for non UHD TV screens and is the same video. It is simply compressed 4 times smaller to 1080p Full HD resolution. You can also choose a Windows screensaver version in both resolutions. These loop by themselves every 3 minutes.
