Source format

What is FLV?

Flash Video (.flv). FLV was the video format of Adobe Flash and of early YouTube. Flash Player was retired at the end of 2020, so FLV files survive mainly in old downloads and archives, and modern players often cannot open them.

Common use: Archived Flash-era web video

Output format

What is MXF?

Material Exchange Format (.mxf). MXF is the SMPTE-standard container of broadcast and professional cameras, such as Sony XDCAM and Canon cinema cameras. It carries professional codecs and timecode metadata; consumer players rarely open it, so MXF is converted for review copies.

Common use: Broadcast and professional camera footage

Questions about FLV to MXF

Is converting FLV to MXF free?
Yes, one file at a time: the converter on this page runs in your browser, files up to 200 MB, no sign-up. The Filoshi desktop app ($29 once, for Windows) converts many files at once and has no size limit.
Does converting FLV to MXF lose quality?
Yes, a little. MXF is a lossy format, so some detail is thrown away when the file is saved. Filoshi re-encodes the video at a high-quality setting, so the difference is usually hard to see. FLV is lossy too, so this is a second round of compression; convert from the original, not from earlier conversions.
Is my FLV file uploaded anywhere?
No. The converter on this page runs in your browser with FFmpeg compiled to WebAssembly; your FLV file is read and converted on your device and never sent to a server. The desktop app works the same way, offline.
Has FLV to MXF been tested?
Yes. FLV to MXF is one of the 1,841 conversions that passed Filoshi's automated test matrix on Windows 11.
Can I convert many FLV files at once?
Yes, in the desktop app. Drop as many FLV files as you like on the window, pick MXF once for all of them, and each file shows its own progress. The new files appear next to the originals, which are never changed.
