Need help?3FR to MP4 Converter
A 3FR file is a Hasselblad RAW photo — a single still frame straight off a medium-format sensor, not a video. This converter takes that one still and renders it as a short MP4 clip that simply holds the image on screen for a few seconds. There is no motion: the output is your photo, frozen, wrapped in a video container that plays on phones, TVs, and social platforms where a RAW file would not open at all.
Why Turn a RAW Still Into a Video
3FR is a capture format meant for editing, not sharing. It carries the unprocessed sensor data and opens only in software that understands Hasselblad RAW — Phocus, recent Adobe Camera Raw, Apple Preview, and a handful of others. The moment you want that frame on Instagram Reels, a TikTok, a YouTube short, or a digital photo frame that expects a video feed, you need a playable format. Converting the still to MP4 gives you a self-contained clip you can drop straight into a video timeline, schedule as a "video" post, or loop on a display — without first developing the RAW and exporting a JPEG by hand.

How to Convert 3FR to MP4
- Upload Your 3FR File: Drag and drop your .3fr onto the page or click "Add Files." You can add several stills at once.
- Pick Merge Images or Video per Image: Choose "Merge images" to string multiple stills into one clip, or "Video per image" to get a separate MP4 for each file.
- Set Duration, Quality Preset, and Resolution: Use the "Duration" dropdown to choose how long each still is held (the default is 5 seconds per frame), set the Quality Preset (Very High is the default), and either keep the original resolution or pick a fixed size.
- Convert and Download: Click Convert and download your MP4. No sign-up, no watermark.
Frequently Asked Questions
Will the MP4 show any motion, or is it just my photo held on screen?
Just the photo held on screen. A 3FR is a single still, so the MP4 has nothing to animate — it displays your frame for the duration you set (5 seconds per frame by default) and then ends. If you upload several stills with "Merge images," you get a slideshow where each image is held in turn, but each frame itself is static.
Does converting to MP4 keep the full RAW quality of the 3FR?
No, and nothing playable can. 3FR holds high-bit-depth linear sensor data for editing; MP4 video is 8-bit and uses H.264 compression for universal playback. The conversion develops the RAW to a standard image and encodes that into the clip, so you keep the framing and detail at the chosen resolution, but you lose the RAW editing latitude. If you want to grade the image first, develop it in Phocus or Camera Raw, then convert.
How is this different from converting 3FR to JPG?
Converting 3FR to JPG gives you a still image you can open in any photo viewer or upload as a photo. Converting to MP4 wraps that same still in a video container so it works wherever a video is expected — a Reels or TikTok upload slot, a YouTube short, or a photo frame that loops video. Pick JPG for a picture, MP4 for a clip.
Can I set the clip length and frame rate?
You control the clip length through the "Duration" dropdown, which sets how many seconds each still is displayed — from a single frame up to 10 seconds per image. With one 3FR, that duration is the length of the whole clip. With "Merge images," the total length is the per-image duration times the number of stills.
Why does the live page show no audio options for this conversion?
Because the source is a photo with no sound. xconvert hides the audio codec controls when the input is an image, so the MP4 it produces has a video track only. If you need music or narration over the still, add it afterward in a video editor.
What resolution and aspect ratio will the MP4 have?
By default the clip keeps the 3FR's own frame shape — Hasselblad medium-format sensors are close to 4:3 — scaled to the resolution you choose. Social platforms often expect a different shape (9:16 for Reels and Shorts, 1:1 for a square post), so a 4:3 still can show side or top-and-bottom bars once uploaded. If you need an exact aspect ratio, crop the still to that shape first, then convert, or pick a matching preset resolution before you download.
Should I output MP4 or MOV for a still-photo clip?
MP4 with H.264 is the most broadly compatible choice and is what social platforms and most TVs expect. If you are staying inside the Apple ecosystem — Final Cut, iMovie, QuickTime — converting 3FR to MOV can fit that workflow more cleanly. The image quality is the same; only the container differs.
Do my uploaded 3FR files stay private?
Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
