To convert other file formats to the "RAW Video Container" file type, you need software like MLV-App or a similar tool.
About MLV files
The .MLV file extension is primarily a Magic Lantern Video file. It is a specialized container format created by the Magic Lantern open-source firmware for Canon DSLR cameras. Videographers use it to capture uncompressed 14-bit raw video sensor data alongside synchronized 16-bit 48kHz audio.
To view or process these raw files locally, professionals typically rely on dedicated open-source tools like MLV-App, Fast CinemaDNG Processor, or MLVFS (Magic Lantern Video File System) to mount the raw data. In rare instances, an .MLV file might instead be a Multi-Layer Video XML project file used by the Media Lovin' Toolkit.
Working with .MLV files presents major workflow bottlenecks. The raw sensor data creates massive files that consume gigabytes of storage in minutes. Furthermore, they are essentially unplayable; standard media players will only display a black screen or fail to open them entirely. Mainstream non-linear editors (NLEs) like Premiere Pro or Final Cut Pro cannot natively import them without an intermediate processing step.
For professional editing and color grading, you should convert .MLV to a CinemaDNG image sequence or Apple ProRes. If you just need to preview the footage or share it on the web, convert it to a highly compressed MP4 or MOV. Drag and drop your file here to analyze and convert it - free, online, and without installing complex camera utility software.

The MLV Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MLV converter.
