MKV stands for Matroska Multimedia Container. It is a video container similar to MOVs and AVIs. The main difference is that an MKV format can hold unlimited amounts of audio, picture, and subtitle tracks (srt as an example). The MKV video format has the ability to store lots of useful information inside the container, like descriptions, ratings, cover art, and chapters. This is why MKV is the chosen format for DivX Plus software and DVDs since it was easy to display cover art and chapter information. MKV was initially released December 6 2002.
FLV format is designed for Flash Video. Flash Video is a container file format used over the internet for Adobe Flash Player version 6 and newer. There are two Flash Video formats, one is FLV and the other is F4V. Adobe flash support both FLV/F4V and was developed by Adobe Systems. FLV was originally developed by Macromedia. In the early 2000s FLV was the standard video format for streaming over the internet. FLV based videos are typically encoded with Sorenson Spark or VP6 video compression formats. Apple iOS devices do not support the Flash Player plugin -- thanks Steve Jobs. So FLV is probably not the ideal format for using on social media sites that are primarily mobile optimizied.
Simply drag and drop your mkv file within the upload zone above. Alternatively you can click the big blue button that says "Upload File". If your file is not of mkv type, then the system will automatically detect the file for you.
Once your mkv video is uploaded (it doesn't have to be mkv, we will automatically detect the format if it's different), you will see a progress bar.
In a matter of seconds (typically) you will see the video, with it's metadata on the right. At the top of the metadata you will see a format dropdown button. The default will be flv, but you can change the format on the fly, once you're happy, you can click the convert button.
Give it a few minutes to convert your mkv file into flv (or which ever formats you have defined). Depending on your settings and the output format it could take a moment.
Be patient on this step, you can enter your email if you would like to get a downloadable link when it is ready. This is nice if you need to leave and get a link while on the go.

The pefect example is social media, typically the best format is MP4 (with H.264 or H.265 codecs) for sites like Instagram, Tik Tok, Twitter, YouTube, etc. So if you are converting your mkv file for social media, we recommend MP4but you are free to convert it to flv if you know what you are doing.
