MXF to MP4 Converter
Convert MXF files from broadcast and professional cameras — Sony XDCAM, Panasonic P2, Canon XF, Avid exports — to MP4 that plays on any phone, computer or TV. Multi-track audio is combined into stereo, interlaced video is deinterlaced, and you keep full control over quality, bitrate, resolution and audio.

Frequently asked questions
What is an MXF file?
MXF (Material Exchange Format) is a professional container used by broadcast and cinema cameras and editing systems, including Sony XDCAM, Panasonic P2, Canon XF and Avid. It usually holds MPEG-2, DNxHD or DNxHR, ProRes, DV or AVC-Intra video with uncompressed audio. Phones, browsers and consumer players cannot open it, so it is converted to MP4 for sharing and review.
Why does my MXF have so many audio tracks?
Broadcast files store each audio channel as its own mono track, often four or eight of them, so track 1 alone is only the left channel. The tool detects this and combines tracks 1 and 2 into a normal stereo track. To use a different channel, choose a single track in the Audio box.
My MXF file is several gigabytes — will it work?
MXF files are very large because their video is barely compressed. The finished MP4 has to fit in browser memory, roughly 1 to 2 GB, which is easy because MP4 is far smaller than MXF; the original is read directly from disk. Re-encoding runs on one CPU thread, so a long HD clip can take several times its length — use Start and End to convert only the part you need, or run the generated ffmpeg command on your own computer.
Can it open a P2 or XDCAM folder?
The tool converts one MXF file at a time. Choose the video MXF from the folder (for example Contents/Clip on XDCAM, or Contents/Video on P2). On P2 cards the audio is stored in separate MXF files in Contents/Audio, and this tool cannot join them to the picture, so a P2 video file converts without sound.
Why does my footage look combed on motion?
Broadcast video is often interlaced. Deinterlace is switched on automatically when the tool detects interlaced video and you re-encode, which gives clean progressive frames.
Is my video uploaded anywhere?
No. The conversion runs entirely in your browser using ffmpeg compiled to WebAssembly. Your video never leaves your device. Only the converter engine itself (about 32 MB) is downloaded, once, and cached by your browser.
What is Fast remux and when should I use it?
A MXF file is just a container. If the video inside is H.264 (or another format MP4 supports) and the audio is AAC, MP3 or AC-3, those streams can be moved into an MP4 container as they are. That takes seconds and loses no quality at all. The tool checks your file and picks this automatically when it is possible.
What do CRF and bitrate mean?
CRF (constant quality) lets the encoder spend as many bits as each scene needs: lower numbers mean better quality and bigger files, around 18 looks near-lossless, 23 is the default and 28 is noticeably smaller. A target bitrate instead aims for a fixed number of kilobits per second, which gives a predictable file size but variable quality.
Why is re-encoding slow, and is there a size limit?
Re-encoding runs on a single CPU thread inside the browser (H.264 only), so it is usually near real-time speed or slower for HD. The finished MP4 also has to fit in browser memory, which in practice limits output to roughly 1 to 2 GB. For a long movie, use Fast remux, trim it, or copy the generated command and run it with ffmpeg on your own computer.
What happens to subtitles?
MP4 supports text subtitles only. SRT, ASS/SSA and WebVTT tracks are converted to the MP4 text format, and you can also save a track as a separate .srt file. Picture-based subtitles from Blu-ray or DVD (PGS, VobSub) cannot be converted.
