Why Convert MOS to AVI?

MOS is the RAW image format from Leaf digital camera backs, used in medium-format professional photography. These high-resolution files require specialized software like Adobe Photoshop (via Camera Raw), Lightroom, RawTherapee, or Darktable to open. Converting MOS images to AVI creates video slideshows and presentations from professional photography — playable on any device without RAW editing software.

Use Cases

• Photography slideshows — Combine a series of Leaf medium-format photos into an AVI slideshow for client presentations or portfolio reviews.
• Studio previews — Create quick video previews from a shoot's MOS files for review on any device without RAW software.
• Timelapse — Assemble sequential MOS captures into a timelapse AVI at 1/24s or 1/30s per frame.
• Legacy compatibility — AVI plays on virtually every Windows computer and media player, making it easy to share professional photography as video.

What is MOS?

MOS is the RAW image format from Leaf digital camera backs (now part of Phase One). Leaf backs are used in medium-format professional photography for advertising, fashion, and fine art. MOS files contain unprocessed sensor data at very high resolutions.

How long will each image display?

You control this with the Image Duration setting. Options range from 1/60s (a single frame) to 10 seconds per image.

Can I merge multiple MOS photos into one video?

Yes. Select "Merge images" under Merge Strategy. All uploaded MOS files are combined into a single AVI video in upload order.

Can I set a background color?

Yes. Under Background Color, choose from Black (default), White, and other colors. This fills the space around images that don't match the output resolution.

What video codec should I use?

MPEG-4 (default) for broad compatibility. H.264 for better compression. DivX or Xvid for classic AVI playback on older devices.
