Understanding MXF files

What is a MXF file?

Broadcast-grade video format for professional production

MXF files were designed by the Society of Motion Picture and Television Engineers. These MXF files, also known as Material Exchange Format files, are the digital equivalent of video tape. These files contain both audio and video data (and can contain other data in parallel bitstreams). You’ll usually encounter MXF files created by cameras, camcorders, video recorders, and on computers. Special codecs are typically required to decode MXF files, as they aren’t as common as other file formats.

Impressed at how seamless Sonix makes editing transcripts. This is so much easier and more enjoyable than manually writing an entire transcript myself.
