Behind every video is a file extension that determines how it is handled by different programs. To date, hundreds of these file extensions exist and many are becoming obsolete because of the advances in technology. FLV video is a good example, which uses Adobe Flash Player or Adobe Air to transmit video or audio over the internet. For many years, it has been the standard video format used by nearly all video websites, including YouTube, Vimeo and more but many streaming sites are now dropping it because of its weakness in terms of security. Besides that, not many native operating systems or applications support this file extension in the present day and a good example is Apple’s iOS. It is a good idea to convert the FLV videos, and AVI video can be very suitable in this case. AVI stands for Audio Video Interleave, and this video file extension was developed by Microsoft. It has several advantages, and the biggest one is its ease of use and universality. It can use less compression as compared to other formats and at the same time preserving good video quality. We will introduce software tools that you can use to convert FLV video to AVI video.
