A .mos file is a Leaf Camera Raw image — a single, uncompressed still photo from a Leaf or Mamiya medium-format digital back, not a video. This tool wraps that one raw frame into a short, silent DivX (.divx) clip that simply holds the image on screen for a set number of seconds. It does not animate the photo or add motion; it produces a playable video file showing your still.
Why Turn a MOS Still Into a DivX Clip?
Most media players, smart TVs, and set-top boxes cannot open a Leaf .mos raw, but almost all of them play a DivX/AVI video. Converting a still to a short clip lets you drop a high-resolution Leaf frame into a slideshow, a video timeline, or a DivX-certified player without first finding raw-aware software. Be aware of two trade-offs: the clip is silent (there is no audio track), and the raw's wide tonal latitude and 12–14-bit colour are baked down to standard 8-bit video. If you only want a viewable photo, convert MOS to JPG instead; if you want a shareable clip, convert MOS to MP4 — H.264/MP4 plays on more modern devices than DivX.

How to Convert MOS to DivX
- Upload Your MOS File: Drag and drop your
.mosfile or click "Add Files." You can queue several stills at once. - Set Image Duration: Open Advanced Options and use Duration to choose how long the still is shown (the default is 5 seconds per frame); this sets the length of the clip.
- Set Background Color and Resolution: Pick a Background Color (default Black) to fill any letterboxing, and use Video resolution to keep the original size or pick a preset — medium-format raws are very high resolution, so a preset usually shrinks the output a lot.
- Convert and Download: Click "Convert" and download your DivX file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.
Frequently Asked Questions
Will the DivX video animate or add motion to my MOS photo?
No. The output is a static clip: it shows your single Leaf raw frame for the duration you set, then ends. There is no panning, zooming, or movement — it is one still image held on screen as a playable video.
Does the DivX clip have any audio?
No. A .mos file is a photo with no sound, so the resulting DivX video is silent. The audio track is intentionally left out for image-to-video conversions; no soundtrack is added.
Will I lose image quality going from a Leaf raw to DivX?
Yes, some. Leaf raws hold 12–14 bits of colour per channel and uncompressed sensor data; DivX video is standard 8-bit and uses lossy MPEG-4 Part 2 compression. The clip looks fine for playback, but the wide editing latitude of the raw is not preserved. For an editable still, export to a high-quality format like JPEG or TIFF first.
Should I use DivX or MP4 for sharing my Leaf still?
For broad compatibility, MP4 (H.264) is the safer choice — it plays on phones, browsers, and modern TVs, while DivX/MPEG-4 Part 2 is an older codec aimed at DivX-certified players and AVI workflows. Use DivX only when your target device specifically expects it; otherwise convert MOS to MP4.
Why is my DivX file so much smaller in resolution than the original MOS?
Medium-format Leaf backs capture very high-megapixel images, far beyond typical video frame sizes. In our testing, leaving "Video resolution" on a preset (rather than "Keep original") downscales the frame to a standard size, which keeps the clip lightweight and playable; choose "Keep original" only if your player can handle the full pixel dimensions.
What software normally opens a .mos file without converting it?
Leaf .mos raws open in professional raw editors such as Phase One Capture One, Adobe Photoshop / Camera Raw, ACDSee, and the free RawTherapee. Converting to DivX (or to a still image) is only needed when you want the photo to play in a video player that does not read raw camera files.
Are my uploaded MOS files kept private?
Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. They are never shared, made public, or used for anything other than your conversion, and no account or sign-up is required.
How long will the DivX clip be, and can I change it?
As long as you set with the Duration control in Advanced Options, which defaults to 5 seconds per frame. Because the output is a single still held on screen, that duration is the whole length of the clip — raise it for a longer hold or lower it for a brief one. There is no motion to time against, so the number simply decides how many seconds your Leaf frame stays visible.
