Be sure to check out our store by clicking on a category above like the 4K video downloads for awesome relaxing screensavers for TVs and computers. Our aquarium videos are some of the best in the world if you want your own “virtual fish tanks” and “nature windows” in your home.

Please note: You must right click on the MP4 videos, then left click on Save Link As (or similar). A single left click is all that is required for the screensavers below.

The below button is for our old 4K H.264 codec videos. If your TV (or computer) cannot play the 4K MP4 above which uses the modern HEVC H.265 codec; it may be able to play the version below instead. This is because H.264 is a more common codec compatible with older devices.

If you need the H.264 version of a 4K video please contact us first to check if we have it. If so we will be happy to email you a direct link to download the alternative version.  Please note that this only applies for small numbers of videos, we couldn’t provide different versions for many videos such as in a download bundle like the Mega Deal.

The file size is 2- 3 times larger for the H.264 videos. We are leaving all Full HD videos in the H.264 format as it is more compatible with older HD devices (which were often made before H.265 was created).

All computer screensavers are currently made from the H.264 files; again for compatibility reasons. If your computer has trouble handling a 4K Ultra HD video, it may be able to play a 4K screensaver instead.

Update August 2017: We are stopping making H.264 now for the 4K UHD videos because it seems that all 4K Ultra HD TVs can handle H.265 videos. However, some people (especially on older computers who haven’t updated their operating system) still need H.264. Our best sellers like Coral Garden, The Ocean Tank and Jellyfish Aquarium are all available in H.264.

    Hi Athanasios.

    Please add the MP4 video to a USB stick and plug that into your TV. Then play the video using the in-built media player. Select Repeat so that it plays continuously.

    If you have a new UHD SMART TV the H.265 MP4 file will work. If you have an older one then you may need to use the H.264. We give out the H.264 ones on request (only need to do that about 1% of the time).
