What is MP4?
MP4, or MPEG-4 Part 14, is a widely used digital multimedia container format designed to store video, audio, subtitles, and still images. It supports high-quality video compression using codecs like H.264 or H.265 and audio formats such as AAC or MP3. MP4 files are compatible with nearly all devices and platforms, including smartphones, computers, web browsers, and media players, making it one of the most versatile and accessible video formats available. Unlike M4V, MP4 typically does not include DRM protection, allowing for broader sharing and playback flexibility.
What is FLV?
FLV (Flash Video) is a container file format used to deliver digital video content over the internet using Adobe Flash Player. It was widely used in the early days of online video streaming, especially on platforms like YouTube and Twitch. However, FLV is less compatible with modern devices and browsers compared to MP4, which is why converting MP4 to FLV is sometimes needed for legacy systems or specific use cases.
