RAF to FLV Converter

RAF to FLV Converter

A RAF is a Fujifilm RAW photo and FLV is Adobe's Flash Video container — a format built for a plugin that no longer exists. This converter renders the RAF to a single frame and wraps it in an .flv as a short, silent clip. Be honest up front: this is a triple mismatch — an archival pro-photo RAW, frozen into a still video, dropped into a dead Flash container. Flash Player reached end of life on December 31, 2020, and no browser plays .flv natively anymore. If you want a normal viewable photo, convert RAF to JPG; if you need the still as a clip that plays everywhere, convert RAF to MP4. Pick FLV only when a specific legacy Flash-based system insists on the .flv extension.

How to Convert RAF to FLV

1. Upload Your RAF File: Drag and drop your .raf onto the page or click "+ Add Files". You can add several at once — Fujifilm RAW files are large, so the upload is the main wait, not the conversion.
2. Set Merge strategy and Image Duration: Choose Merge images to combine several RAFs into one FLV or Video per image for a separate clip each, then set Image Duration (default 5 seconds per frame) for how long each photo holds on screen.
3. Pick Background Color and Quality Preset: Background Color (default Black) fills any letterbox bars when the photo's shape differs from the video frame; leave Quality Preset on Very High (Recommended) or choose a Video resolution preset to cap the output size.
4. Convert and Download: Click "Convert" and download your FLV. No sign-up, no watermark.

What You're Actually Getting

A single RAF is one still photograph — there is no motion inside it — so a one-file conversion produces a freeze-frame clip: the rendered image held on screen for the Image Duration you set, with no panning and no movement. Because a still photo carries no audio, the FLV is silent by design; on this converter, image-to-video conversions write no audio stream at all. Two consequences are worth understanding. First, the render bakes in your photo: a RAF stores the unprocessed sensor readout that must be demosaiced and tone-mapped to become viewable, and most Fujifilm X-series bodies use the X-Trans color filter array — a 6×6, non-Bayer pattern rather than the standard Bayer mosaic on nearly every other camera — which some demosaic engines render slightly differently (GFX medium-format and older Fujifilm bodies use a conventional Bayer grid). Whatever the engine, the converter applies a standard render that locks in white balance, exposure, and color, so the RAW editing latitude is gone once it is a video frame. Second, almost all the resolution is discarded: a Fujifilm RAF is roughly 16-40 megapixels on X-series APS-C bodies and 100+ megapixels on GFX, while an FLV frame is encoded at standard-definition-to-1080p sizes, and FLV1 (Sorenson Spark) is an old H.263-era codec far less efficient than H.264. Keep the master RAF — the FLV is a delivery file, not an archive.

Frequently Asked Questions

Is FLV still supported in 2026, or should I use MP4 instead?

For almost any new use, MP4. Adobe Flash Player reached end of life on December 31, 2020, and Adobe began blocking Flash content on January 12, 2021, so no current browser plays .flv natively. The container still opens in VLC and ffmpeg-based players, which is enough to inspect a file, but it is a poor delivery format today. Convert RAF to MP4 for an H.264 clip that plays on phones, browsers, and modern editors, or RAF to JPG if you simply want the photograph.

Which video codec does the FLV output use, and is there sound?

The video defaults to FLV1 — the Sorenson Spark codec, a proprietary variant of the H.263 standard and the original codec Flash Player required. In the Video Codec menu you can also pick Flash Video and Flash Video (v2) screen codecs, H.264, or MJPEG, but FLV1 is the convention for a basic .flv. There is no audio: because the source is a single still photo, the converter writes no audio stream, so the clip is silent. In our testing, a single 26-megapixel X-Trans RAF rendered at the Very High preset produced a short, silent FLV1 file that opened in VLC without an extra codec download but would not play in Chrome or Edge.

Does converting a single RAF to FLV create any motion or animation?

No. A RAF is one still photograph, so a single-file conversion produces a freeze-frame clip — the rendered image held on screen for the Image Duration you set, with no panning or movement. To build a moving sequence you need multiple RAFs merged together with Merge images; there is no motion inside a single Fujifilm RAW to animate.

Will I lose image quality going from RAF to FLV, and does X-Trans matter?

Yes, substantially, and it is inherent to the conversion rather than a tool flaw. A RAF holds unprocessed sensor data — on most X-series bodies arranged in Fujifilm's X-Trans 6×6 array rather than a standard Bayer grid — that must be demosaiced to become viewable, baking in white balance, exposure, and tone. A 16-40 MP RAW (or 100+ MP on GFX) is then scaled down to an FLV frame, discarding most of the resolution, and the default FLV1 codec is an older H.263-era format far less efficient than modern codecs. The X-Trans pattern mainly affects fine demosaic detail at the pixel level, which is mostly moot once the frame is downscaled. Keep the original RAF as your master for any future editing.

Can I play an existing FLV file or convert it to something modern?

You can open .flv files in VLC or any ffmpeg-based player, but not in a browser, since Flash Player is gone. To make an old FLV usable on modern devices, convert it with FLV to MP4, which rewraps the video into the widely supported H.264/MP4 combination. That is a separate, video-to-video conversion from this RAF-to-FLV tool, which only renders a Fujifilm RAW still into a frame.

Should I convert RAF to FLV at all, or to MP4 or JPG instead?

For nearly every purpose, convert to something else. FLV targets a Flash runtime that no longer exists, so it makes sense only when a specific legacy system requires the .flv extension. If you want to view, print, or share the photo, RAF to JPG gives you a normal, universally viewable image. If you genuinely need the still as a playable clip, RAF to MP4 produces an H.264 video that plays on phones, browsers, and editors everywhere.

What happens to my uploaded RAF file after conversion?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion — no sign-up, no watermark, never shared or made public.
