Full named as Nullsoft Streaming Video, NSV is a media container file designed for streaming video content over the internet. It is seldom for us to find NSV video file in the market. If you have NSV in hand and want to convert it to other video formats, you can give MOV output as a try. Here I will introduce 4 methods for you to convert NSV to MOV. Previously, we have discussed how to convert NSV videos.

Part 1: About NSV and MOV

NSV is the first media container file to break the restrictive internet video broadcast barrier. It has allowed anyone to produce and distribute live or recorded video content over the internet, which was not possible before its introduction. Its special features include – supports any combination of audio and video formats; is most suitable for streaming because of its ability synchronize accurately at any point of the stream; is a bitstream format, which means it does not require a whole file or the beginning of a file to begin playing; and supports auxiliary data chunks for sending multiple audio tracks, subtitles, or other data. The NSV file has a simple structure. It consists of a header (containing information such as file length, a table of contents, and other general metadata), and the bitstream (consisting of a sequence of NSV frames). Although NSV was released in 2003 and began to be used almost immediately with Nullsoft’s Winamp, its real popularity began only after the release of Winamp version 5. This is because Winamp v.5 came with a Media Library which offered integrated listings of all audio and video streams. The earlier versions only had a Library.

MOV is a popular video format file originally developed by Apple. It was intended to support its QuickTime movie player and often used to save videos, movies, etc. It uses an advanced algorithm especially developed by Apple and is compatible across different versions of Mac and Windows operating systems. It uses the concept of tracks to store data. A track, which stores a particular type of data, is stored in a multimedia container file. There are many such tracks present in the container. There are different tracks meant for holding different types of data like text, audio, video, etc. Such tracks maintain a hierarchy consisting of atoms as an object. In addition, it uses a specific format to contain a digitally encoded media stream. If the digitally encoded media stream is present in some other file, it makes a data reference to the media stream. There are various advantages associated with MOV format, which makes it much more popular and usable format for videos. However, it has some proprietary issues.
