What is FLV
FLV (Flash Video) was once the standard for online streaming via Adobe Flash Player. Now considered outdated, FLV files use older codecs like Sorenson Spark and lack mobile support. Modern websites have shifted to HTML5 video with MP4 or WebM formats. FLV remains relevant only for legacy content conversion.
What is MP4
MP4 (MPEG-4 Part 14) is the most popular video format for online sharing, streaming, and storage. It uses H.264 or H.265 video encoding with AAC audio, ensuring high compatibility across devices, social media platforms, and video players. MP4 files balance quality and compression, making them ideal for YouTube, Instagram, and professional video production. Its universal support makes it the go-to format for most users.
