FLV to MP4 converter

FLV stands for Flash Video, and is a container file format used for delivering online video content in the Adobe Flash Player software. FLV files usually contain video data encoded with the Adobe Flash Video (FLV) codec and audio data encoded with either the MP3 or AAC codec.

The FLV file format is widely used for streaming online video content, and can contain metadata such as title, author, copyright, description, video creation date, and so on. Although FLV files are considered a legacy file format, they're still widely supported by many multimedia players, web browsers, and mobile devices.

MP4 is a popular digital multimedia container format standardized by the Moving Picture Experts Group (MPEG). It stores both audio and video streams in compressed form, including subtitles, images, and other data. An MP4 file is typically composed of different data types, such as H.264 and AAC compressed audio/video streams, text (e.g., subtitles), metadata, and additional data describing the media content.

MP4 files are widely used for streaming over the Internet, due to their good compression ratio and compatibility with most major video platforms, including YouTube and Vimeo. They are also now commonly used as the container format for HDTV broadcasts and Blu-ray discs.
