FLV or Flash Video is a digital video format. It was originally developed by Macromedia and later acquired by Adobe Systems to deliver high-quality videos over the internet using Adobe Flash Player. FLV files were widely used for streaming on platforms like YouTube and Vimeo before HTML5 became the standard for online video playback.
MP4, short for MPEG-4 Part 14, is a popular digital video format developed by the Moving Picture Experts Group (MPEG). It's widely used for storing video, audio, subtitles, and images, compatible with almost all devices, making it ideal for video conversion, streaming, and sharing.
FLV and MP4 are both video formats. FLV (Flash Video) is an older format once popular for web streaming, especially on Flash-based sites. MP4 is a modern, widely supported format used for videos on almost all devices, from smartphones to PCs, and is compatible with streaming, editing, and social media platforms.
