MXF to FLV Converter
Processing entirely on your device — large files may take a moment.
Material Exchange Format and Flash Video exist for different jobs: MXF is the broadcast-industry media container — XDCAM, P2 cameras and TV stations hand off program material as MXF with embedded metadata. Rescuing FLV recordings means converting them to MP4 before Flash compatibility disappears completely.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the MXF format
MXF (Material Exchange Format) is the container broadcast television standardized on: XDCAM and P2 cameras record it, newsrooms hand off program material in it, and playout servers ingest it. Beyond the video and audio tracks it carries structured metadata — timecode, program markers, rights information — that plain MP4 cannot express.
For editing and review the container is the problem, not the content: converting MXF to MP4 or MKV keeps the H.264 video and PCM audio intact while making the file openable in any editor and shareable in chat. Broadcast cameras also interlace, so check the output for field order.
+ Strengths
- ✓Broadcast-grade metadata and timecode
- ✓Industry standard for program exchange
- ✓ffmpeg decodes XDCAM/IMX/D-10 variants
! Limitations
- −OP1a vs OP1b patterns differ by vendor
- −Metadata is dropped on conversion
- −Files are heavy (broadcast bitrates)
About the FLV format
FLV (Flash Video) was the video format of the early streaming web — YouTube's original delivery container from 2005 to ~2010, played by Adobe Flash Player. Later versions carried H.264/AAC, but the container lived and died with Flash, which reached end-of-life in 2020.
Modern browsers cannot play FLV at all, and only niche players (VLC) bother. If you have an FLV archive, converting to MP4 recovers the same H.264 video into a container every device accepts.
+ Strengths
- ✓Only relevant for early-web video archives
! Limitations
- −Dead ecosystem — Flash ended in 2020
- −No browser support at all

Converting makes sense where the strengths of FLV meet what MXF cannot give you. Only relevant for early-web video archives Meanwhile OP1a vs OP1b patterns differ by vendor One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MXF to FLV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MXF to FLV?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting MXF to FLV re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
