RAF to MTS Converter

Convert RAF to MTS Online

This turns a Fujifilm .RAF raw photo into an MTS clip — the AVCHD format camcorders record to — by developing the raw frame and holding it on screen for a set number of seconds. It's a niche conversion: you'd reach for it to drop a still into an AVCHD camcorder timeline, a Blu-ray-style authoring project, or any editor that wants .mts source. The result is a static, silent clip at the duration you choose, not a moving video, and the rendered frame uses a neutral development — so a Velvia or Classic Chrome look from your camera preview won't carry over unless you bake it in first (details below).

How to Convert RAF to MTS

1. Upload Your RAF File: Drag and drop your Fujifilm .RAF files onto the page or click "+ Add Files" to browse. Queue several at once, then pick "Merge images" to lay them into one clip or "Video per image" for a separate MTS each.
2. Set the Image Duration: Open Advanced Options and choose how long each still is held under "Image Duration" — it defaults to 5 seconds per frame, with a dropdown ranging from a single frame up to 10 seconds.
3. Choose Resolution and Background Color (Optional): Leave "Quality Preset" on "Very High (Recommended)", set a "Fixed Resolution" such as 1920×1080 since a 26-40 MP Fuji frame far exceeds HD, and pick a "Background Color" (black by default) that shows around the photo when its aspect ratio doesn't fill the frame.
4. Convert and Download: Click "Convert" and save your MTS. No sign-up, no watermark.

RAF and MTS — What the Conversion Does

Frequently Asked Questions

Why does the MTS frame look different from my Fujifilm camera preview?

Two reasons. The in-camera preview applies a Film Simulation — Velvia, Astia, Classic Chrome, Acros and so on — that isn't stored as pixels in the RAF; it's a render-time instruction. A faithful, neutral development of the raw data won't reproduce that look. On top of that, most Fujifilm X-series bodies use the X-Trans color filter array, a non-Bayer 6×6 pattern that every renderer demosaics with its own algorithm (GFX medium-format and some entry models use a conventional Bayer array instead). If the film-simulation look matters, apply it in a RAF-aware editor such as Capture One or Fujifilm's own RAW converter, export the finished frame, and convert that to MTS.

Will the MTS clip have motion or sound?

No. A single RAF is one photograph, so the MTS holds that one frame on screen for the duration you set under "Image Duration" — it doesn't move, and this conversion produces a silent clip with no audio track. If you want motion, upload several RAF files and use "Merge images" to play them in sequence, which makes a simple slideshow-style clip rather than continuous footage. For an actual soundtrack you'd add audio later in a video editor.

Do I lose my RAW editing latitude converting RAF to MTS?

Yes. A RAF holds undeveloped sensor data, which is why white balance, exposure, and highlight recovery stay adjustable while it's raw. To make the MTS, the converter develops the photo first — demosaicing the sensor data and baking in the current white balance, exposure, and tone — so the frame in the video is finished, not an editable negative. Keep the original .RAF as your master if you might want to re-develop later. If you only need an editable still rather than a clip, convert RAF to JPG instead.

What resolution will the MTS be, given my camera's megapixels?

AVCHD tops out at HD — 1080i or 720p — so a full-resolution Fuji frame (a 26 MP X-T5 sensor is roughly 6240×4160, and 40 MP bodies are larger still) gets downscaled to fit. Set a "Fixed Resolution" such as 1920×1080 under Video resolution so you control the result; otherwise the frame is scaled to the target you pick. Because the photo's 3:2 aspect ratio doesn't match 16:9, you'll see the "Background Color" fill the gaps — leave it black or change it to taste.

Should I really use MTS, or would MP4 be easier?

Use MTS only if your target genuinely wants AVCHD — an older camcorder edit, a transport-stream authoring workflow, or software that imports .mts. For almost anything else, MP4 is more universal and plays nearly everywhere; convert RAF to MP4 is the easier path for a shareable clip. If you just want a high-quality still for print or editing rather than a video, skip the clip entirely and use RAF to JPG or RAF to TIFF.

How large a RAF can I upload, and how is my file handled?

In our testing, a full-resolution Fujifilm RAF developed into a short 1080p MTS produced a modest file, since a static frame held for a few seconds compresses efficiently in H.264. Your file is uploaded over an encrypted connection, developed and encoded to MTS on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The practical limit is upload size and time rather than your device, since raw files often run tens of megabytes each.
