MKV to FLV Converter FAQs
This is a very specific conversion used almost exclusively for maintaining or updating legacy systems. FLV (Flash Video) is an outdated format for the discontinued Adobe Flash Player. You would only need to convert an MKV to FLV if you are required to upload a video to a very old website or application that was built with Flash technology and cannot be updated.
These advanced features will be completely lost during the conversion. The older FLV format does not have any support for multiple audio or subtitle streams. The converter will typically select only the default audio track from your MKV file and will have to discard all other audio tracks and any embedded subtitles.
Yes, there will be a noticeable loss of quality. The modern, high-efficiency video and audio streams inside your MKV file must be re-encoded into older, less efficient formats that the FLV container supports. This "lossy" re-compression process will permanently discard some of the original visual and audio detail.
No, absolutely not. FLV is considered a dead format for the web. Adobe has officially discontinued the Flash Player, which was required to play FLV files. As a result, no modern web browsers or mobile devices support the FLV format, and it will not work for a modern audience.
For any modern web use, you should convert your MKV file to the MP4 format. MP4 is the universal standard for all web video and is supported by every current browser, smartphone, and video-sharing platform like YouTube. It offers an excellent balance of high quality, efficient compression, and universal compatibility.
