3FR to MTS Converter

Converting a Hasselblad 3FR to MTS: What This Tutorial Covers

A .3fr file is the RAW capture written by a Hasselblad H- or X-system medium-format camera — proprietary sensor data, built on a TIFF container, that nothing outside Hasselblad Phocus, Lightroom, or Camera Raw opens directly. An .MTS file is the camcorder spelling of an AVCHD video stream, the format Sony and Panasonic HD camcorders record to. This walk-through is for the narrow but real case where you need to drop a Hasselblad still into an AVCHD-era editing or disc-authoring timeline that only ingests .mts footage — and it is honest about what that costs: this converter does not "open a RAW in a video editor." It renders the 3FR down to one video-sized frame and wraps that single motionless frame in a transport stream — a silent, static clip held on screen for a duration you choose. If you actually want a viewable picture, almost everyone should use 3FR to JPG instead, and for a print master, 3FR to TIFF.

How to Convert 3FR to MTS

1. Upload Your 3FR File: Drag and drop your .3fr onto the page or click "+ Add Files" to browse. You can queue several captures, though each medium-format RAW can run from tens to over a hundred megabytes.
2. Set Image Duration: Open the "Image Duration" control and pick how long the rendered frame is held — from a single frame up to 10 seconds per frame; the default is 5 seconds per frame. Use "Merge strategy" to pick "Merge images" (one combined clip) or "Video per image" (a separate .mts per photo).
3. Set Quality Preset, Video resolution, and Background Color (Optional): Leave "Quality Preset" on "Very High (Recommended)", choose "Video resolution" ("Keep original" or a fixed preset such as 1920x1080), and pick a "Background Color" (default Black) to pad any letterboxed area. "Video Codec" defaults to H.264 under Advanced Options, which is what AVCHD tools expect.
4. Convert and Download: Click "Convert" and save your silent .MTS clip. No sign-up, no watermark.

Walk-through: The Two Settings That Decide the Result

This conversion has more honesty riding on its settings than most, because two of them quietly throw away the very thing a Hasselblad file is prized for. Here is how to think about each:

• Resolution is a massive, deliberate downscale. A Hasselblad medium-format back captures an enormous frame — roughly 39 megapixels up to 100-plus on current bodies — which is many times more pixels than any 1080p-class video frame can hold. Leaving "Video resolution" on "Keep original" still produces a video-sized frame, not a poster-sized one, and a preset like 1920x1080 downscales the rendered image to fit. The detail that does not fit the chosen frame is discarded. If preserving every pixel matters, stop here and use 3FR to TIFF for the print master instead of wrapping it in video.
• The RAW render bakes in your look. To put a 3FR into any video frame, the converter demosaics the sensor data and bakes in a white balance, exposure, and tone — the way a RAW developer applies them — because transport-stream video has no concept of undeveloped RAW data. The frame inside the .MTS is a finished 8-bit video frame, not an adjustable sensor readout. If you grade carefully, set white balance and exposure in Phocus first and export, then convert that file. And always keep the original .3fr as the irreplaceable studio master.
• Duration and Merge strategy shape the clip. A longer "Image Duration" holds the still longer on the timeline; "Merge images" joins several stills back to back into one clip, each shown for its set duration, while "Video per image" writes one .mts per photo.

Common Errors and How to Fix Them

• "The clip is completely silent." That is expected, not a fault. A still image carries no audio track, so there is nothing to encode into the AVCHD stream — even though AVCHD itself supports Dolby AC-3 and linear PCM. Add narration or music on the editing timeline after you import the clip.
• "The photo doesn't move." Also by design. The 3FR is rendered to one frame and that single frame is held for the duration you set, so it plays as a frozen clip with no pans, zooms, or transitions. For motion, animate the still on your editing timeline.
• "The image looks soft or low-resolution compared to the RAW." Squeezing a 39-to-100-plus-megapixel capture into a 1080p-class frame is a huge downscale; the video frame simply cannot carry medium-format detail. Keep the still as 3FR to TIFF if resolution is the point.
• "The white balance or tone looks off." That look was baked in when the RAW was rendered with default settings. Adjust exposure and white balance in Hasselblad Phocus on the original .3fr first, then convert the exported file.
• "My 3FR won't load at all." It may be from a camera body newer than the converter's RAW library recognizes, or the file may be a partial copy. Re-save it to DNG or TIFF in Phocus first, then convert that interim file, or re-copy the original from the card.

When This Doesn't Work

3FR to MTS is a deliberately niche conversion: the honest use case is feeding an AVCHD-era editor or disc-authoring tool that only ingests .mts transport-stream footage with a title card, slate, or studio still. For nearly everything else it is the wrong target. If you only want to view or share the shot, 3FR to JPG gives you a web-ready picture; for retouching and print, 3FR to TIFF keeps the full resolution; and for a modern video file that plays on phones, browsers, and ordinary editors, 3FR to MP4 carries the same H.264 video in a smaller, far more compatible file. What you download here is also a bare transport stream, not a camera-card folder structure, so copying it to an SD card will not rebuild a browsable AVCHD volume — software players like VLC and AVCHD-aware editors handle it, but a set-top player navigating a card may not. For an .mts from any image, not just Hasselblad RAW, see Image to MTS. And a genuinely corrupted .3fr cannot be rescued by any converter — re-copy it from the original card or backup.

Frequently Asked Questions

Why would I convert a 3FR photo to MTS instead of MP4?

Almost the only reason is an AVCHD-era pipeline. If you are building or authoring a project in an older editor or disc tool that ingests .mts transport-stream footage and you need to drop in a still, an .MTS clip slots into that timeline without a re-wrap. For every other purpose, 3FR to MP4 carries the same H.264 video in a smaller file that plays on phones, browsers, TVs, and ordinary editors. If you only want a viewable picture rather than a video at all, render 3FR to JPG instead — that is what most people reaching this page actually need.

My 3FR is from a 100-megapixel Hasselblad back — what resolution does the MTS end up?

Far lower than the RAW, and that is unavoidable. A Hasselblad medium-format frame in the roughly 39-to-100-plus-megapixel class holds many times more pixels than any video frame, so leaving "Video resolution" on "Keep original" still produces a video-sized frame, and a preset such as 1920x1080 downscales the rendered image to fit. The detail that does not fit the chosen frame is discarded — squeezing a medium-format capture into a 1080p-class video is a massive downscale by design. If preserving every pixel matters, keep the still as 3FR to TIFF rather than wrapping it in video.

What happens to the RAW editing latitude when I convert to MTS?

It is spent at the render step. A 3FR stores unprocessed sensor data, which is why white balance, exposure, and highlight recovery stay adjustable in Phocus or Lightroom long after the shot. To write any video frame the converter must demosaic that data and bake in a white balance, exposure, and tone, because transport-stream video has no concept of undeveloped RAW. The frame inside the .MTS is a finished 8-bit video frame, so that latitude is gone. Grade in Phocus first if you want control, and always keep the original .3fr as your master.

Does the MTS clip animate the photo or include any sound?

No on both counts. The 3FR is rendered to one still frame, and that single frame is held on screen for the duration you set, so it plays as a frozen clip with no pans, zooms, or transitions. It is also silent: a still image carries no audio track, so there is nothing to encode into the AVCHD stream, even though AVCHD supports Dolby AC-3 and linear PCM. If you upload several files and choose "Merge images" under Merge strategy, they join back to back — a sequence of stills, not a cross-faded slideshow. Add motion and audio on the editing timeline after import.

Isn't 3FR already based on TIFF — why does the conversion bake in a render?

The 3FR container is built on TIFF, but that does not make it a finished image. A 3FR holds raw, undemosaiced sensor data plus Hasselblad-specific tags — Hasselblad introduced the format in 2006 with the H2D, and Phocus is its native processor. To wrap a still in an AVCHD transport stream the converter must first develop that sensor data into an ordinary, viewable frame, then encode it with H.264. That is why the render is unavoidable: a video frame cannot carry undeveloped RAW, only a finished picture.

How are my files handled during conversion?

Your 3FR is uploaded over an encrypted connection, rendered and wrapped into an .MTS clip on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, and your photos are never shared or made public. In our testing, a single Hasselblad 3FR rendered into a 1080p .MTS held for five seconds produced a small clip, since one static frame compresses efficiently in H.264; the main practical limit on a big job is upload size and time, since medium-format 3FR captures often run from tens to over a hundred megabytes each, not your device.
