Part 4. FLV vs MP4

What is FLV?

FLV is simply defined as the Flash video file format. It was created by Macromedia for the exclusive use of the Adobe Flash Player. These videos are commonly embedded in SWF files. Flash video is very popular over the internet. As a matter of fact, it is the format of choice by many video sharing sites such as YouTube, VEVO, Hulu, MetaCafe, and Yahoo! Video. It is also the video format adapted by the news agency Reuters.com for their news website.

What is MP4?

MP4 is the standard video format created by Moving Pictures Experts Group and is certified by ISO. It is the format widely used in streaming media, DVD's, videophones, and even broadcast television. MP4 is also the same as MPEG-4, which is the latest variation of this file format. MP4 is still being improved and tweaked up to this day.

FLV vs MP4

For the longest time, MP4 and FLV are battling it out head-to-head as far as video file format popularity over the internet is concerned. Online videos became the turf of the FLV before, since the Flash plug-in for browsers are highly available and easily downloadable. FLV makes it easier for web owners to display videos and their visitors to watch them. But now, the MP4 format is functioning almost in the same way. Modern browsers can now support the playback of MP4 videos in the same way they can work with FLV. As a result, many of today's HTML5-based web pages are opting for the more easily created MP4 video files for their websites.
