What is unique about the FLV file format?

The FLV file format is distinctive primarily because it is designed specifically as a Flash video format, which facilitates the streaming of video content over the internet. This format was widely used during the era when Adobe Flash was a dominant web technology. Its encoding allows for the efficient delivery of video content in a way that minimizes bandwidth usage while still maintaining decent quality, making it a popular choice for online video platforms.

The focus on online video delivery means that it is optimized for fast streaming and can be played back in web browsers and on various devices that support Adobe Flash Player. While the other options refer to formats used for audio, image storage, or video editing, none capture the specific purpose and functionality of the FLV format in the context of online video streaming.
