FLV Video Format

FLV Converter

FLV stands for Flash Video file, and is a file format developed by Macromedia (now owned by Adobe Systems) for streaming video over the web using Adobe Flash Player. It’s a container format, consisting of a header and packets of metadata, as well as the synchronised video and audio data streams.

In the early days of YouTube and online video sharing, FLV became the de facto file type for most video players. Over time, and with the move to HTML5 as the Apple standard for streaming video, popularity of the FLV format waned. Since 2020, the format has no longer been supported by Adobe and web browsers, and Adobe advises uninstalling the Adobe Flash Player due to security concerns. However, you should still be able to open FLV files with VLC, Nullsoft Winamp, Windows Media Player Classic, and Adobe Animate.

MP4 Video Format

MP4 Converter

MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.

MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.
