This article will give you insights about how to open NSV files on Mac and PC, along with the best NSV player.

The NSV format is not very common. Although someone said it's compatible with QuickTime and Windows Media Player that comes with your operating system, I did fail to play NSV files on them (QuickTime 10.4 and Win 7). What if you receive an NSV file but don’t know how to open it? Read on to get the solution.

What is NSV File?

NSV file, developed by Nullsoft, is a media container that can hold multiple audio tracks, subtitles, and other data. It aims squarely at streaming video clips over the Internet. Format NSV is not frequently present on many devices, but it seems popular on Windows 10 in the United States.

Extension .nsv
Full Name Nullsoft Streaming Video File

Don't confuse the spelling of NSV with other file formats, such as SV (SystemVerilog File), BSV (BSAVE Image), GSV (Gameshark SP Save File), NSD (BLAST Nucleotide Database), CSV (Comma-separated values), etc.

# Winamp

OS Platform: Mac OS X 10.6 and above; Windows 10, 8.1, 8, 7, Vista, XP, etc.

The reason why we recommend Winamp is that it was made by Nullsoft, the same developer as NSV. It has been around for a long time, which is a multimedia player enabling you to play 70 audio and video formats.

However, I think Winamp is more effective for Windows users. On the one hand, there is only a Windows version to be downloaded on its official website. If you desire to download Winamp for Mac, you have to search for the download sites that offering a Mac version. On the other hand, when I tried to open NSV file using Winamp Ver0.8.1.13, it always said “Some of the audio files are not supported by Winamp for Mac”. Even if I imported MP4 files, I still obtain the same error message. Therefore, the Mac version and the Windows version may be different.

Steps to Open NSV File on PC via Winamp:

Step 1. Download and install the program from https://www.winamp.com/. After installation, initiate it.

Step 2. Drag the NSV file to the main screen.

Step 3. From the left pane, select the “Video” category under the “Playlist” tree.

Step 4. Click the NSV video you added, and it will start to play.

How to Open NSV File Using Online NSV Player?

FILExt is a free online provider designed for viewing a wide variety of file types, including NSV, MP4, MKV, MP3, PowerPoint, text, subtitles, zip, image, PDF, etc. But it’s not friendly to open NSV file. Because no matter how long your NSV video is, it can only play the first 30 seconds. For people with unstable network, online NSV player is not a good choice either.

  1. Visit https://filext.com/file-extension/NSV in your browser.
  2. Click the “Choose your .nsv file to play” button. A pop-window appears, and then you can add NSV from your computer. Or drag and drop the NSV file to the specified area.online nsv player 01
  3. Once the data is loaded, the NSV file will be played automatically.online nsv player 02

Convert NSV File to the Common-used Formats like MP4

If you feel disinclined for downloading extra media player on your devices, you can convert NSV to the formats supported by your player, and then open the converted NSV file.

Using an Online NSV Converter

There are not many online converters that support importing NSV video, and files-conversion.com is one of them. It lets you convert NSV file to 18 formats, like MP4, AVI, FLV, SWF, MOV, DV, DVD, MP3, WMA, and more. Another great feature of this online NSV converter is that it gives you options to change the video quality and video size. But it can’t convert multiple NSV files in batch and the maximum video size should be 300M.

  1. Go to https://www.files-conversion.com/.
  2. Click “Select a File” to upload NSV video from your local device.convert nsv online 01
  3. Choose MP4, MOV, WMV, or other media formats as output.
  4. If needed, configure the video quality (4 levels, from low to very high) and video size (or just keep the same size).
  5. Click "Convert" to process the file. When finished, download the converted video.convert nsv online 02
  6. Open NSV file on Mac or Windows with your own media player.
