If you have stumbled upon an NSV media, and are looking for an NSV file player to see the contents it has, you are at the right place. Here you will learn how to watch an NSV video, and some of the most entrusted methods to convert such a file to a more common and widely compatible format such as MP4, AVI, MOV, etc.

Part 1. What is an *.nsv file

NSV stands for Nullsoft Streaming Video, and the audio and video information that are packed in this format use the NSV file extension. As it is with MP4 or other similar media types, even NSV is a container that holds both visual and acoustic details, and therefore can be viewed only on the media players that have the compatible codecs.

As the name suggests, NSV clips are generally used for streaming due to the popularity and ease of accessibility the format comes with. However, because Radionomy bought Nullsoft in 2014, the NSV files are no longer supported by many platforms and players now.

Part 2. How to open *.nsv files with NSV converter and player

An all-in-one media converter that still supports *.nsv format is UniConverter by Wondershare. Wondershare UniConverter has its own previewer that allows you to view the contents of an imported file before you can make any changes to it, or convert it to a different extension. This previewer can be switched to the full screen mode while working with the NSV files, thus enabling you to use the program as a full-fledged NSV file player.

Furthermore, Wondershare UniConverter is capable of recognizing other 1000+ formats, and has a built-in video editor and media compressor to make your post-production and transcoding experiences smooth and flawless.
