Convert AVI to FLV

About AVI

AVI (Audio Video Interleave) is one of the oldest video formats, developed by Microsoft in 1992. As a container format, it can use a wide variety of codecs for video and audio. While it was once extremely popular, it has been largely superseded by more modern formats like MP4. It lacks modern features like native support for streaming or subtitles and can result in very large file sizes.

About FLV

FLV (Flash Video) is a container format that was used to deliver video over the Internet using the Adobe Flash Player. For many years, it was the de facto standard for web video, used by sites like YouTube and Hulu. However, with the decline of Flash due to security issues and the rise of HTML5 video, FLV is now a deprecated and obsolete format.

Frequently Asked Questions

Is AVI still a useful format?

For new video projects, AVI is not recommended. Its main use today is for compatibility with older systems or legacy content. Modern formats like MP4 offer better compression, more features, and wider compatibility.

Why do some AVI files not play audio?

This is a common issue with AVI files and is due to its reliance on codecs. The AVI file itself is just a container. If your system does not have the specific audio or video codec installed that was used to create the file, it will not be able to play correctly.

Is Flash completely dead?

Yes, Adobe officially ended support for Flash Player at the end of 2020, and all major browsers have removed it. While FLV files can still be played in some media players like VLC, the technology is considered obsolete and should not be used for new content.

Why was Flash replaced by HTML5?

Flash was replaced because it was a proprietary plugin that suffered from poor performance, security vulnerabilities, and a lack of support on mobile devices. HTML5 video is a web standard that is built directly into browsers, making it more secure, efficient, and universally compatible.
