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 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 delivers better quality than FLV, with higher resolution, modern codecs, wider device support, and efficient compression. FLV is outdated and was mainly for streaming. Today, MP4 is the go-to format for playback, editing, and versatile video conversion.
