X3F to DivX Converter

How to Convert X3F to DivX Online

1. Upload Your X3F Files: Drag and drop one or more .x3f files from your Sigma SD, DP, Merrill, or Quattro camera, or click "+ Add Files" to browse. The page reads the Foveon RAW directly on our servers — no Sigma Photo Pro pre-processing required. Order the files in the sequence you want them to appear in the slideshow.
2. Pick a Merge Strategy: Default is Merge images — every uploaded X3F becomes one continuous .divx slideshow. Switch to Video per image if you want a separate DivX clip for each frame (useful when each shot is a self-contained subject the recipient will scrub independently).
3. Set Image Duration, Background, and Resolution (Optional): Image Duration defaults to 5 seconds per frame and accepts 1/60s through 10s — drop to 1/24s for cinematic-rate playback, push to 8–10s for portfolio review. Background Color (default black) pads any aspect-ratio mismatch between the X3F and the output frame; pick white for print proofs or a brand color for client deliverables. Video Resolution keeps original by default; for legacy DVD player playback choose the 480p preset (NTSC) or 576p (PAL), or 1080p / 4K for HD displays. Quality Preset under File Compression defaults to Very High (Constant Quality mode); switch to Constraint Quality if you need a specific bitrate ceiling.
4. Convert and Download: Click Convert and the page builds an MPEG-4 ASP video in an AVI container with the .divx extension. Files process locally — no sign-up, no watermark, no account.

Why Convert X3F to DivX?

X3F is Sigma's RAW format produced by Foveon X3 cameras — the SD9 (2002) through the SD Quattro H (2016) and the dp Quattro compacts. Unlike Bayer-filter RAW (CR2, NEF, ARW), Foveon stacks three photodiodes vertically at each photosite, capturing red, green, and blue at every pixel without demosaicing. The downside: X3F files are large, opaque to most photo viewers, and won't play on any consumer video device. Converting a sequence of X3F frames to a .divx slideshow turns a folder of unviewable RAWs into a single file a 2005-era DVD player, an in-car infotainment unit, or a hotel-TV USB port will actually decode.

• Legacy DVD player playback — DivX Certified hardware (Philips, Samsung, LG, Sony set-top players shipped from roughly 2004 onward) decodes .divx AVI directly off a burned disc or USB stick. Useful when you need to hand a client or relative a physical disc that "just plays."
• In-car head units and older infotainment — many 2008–2015 OEM head units (Pioneer AVH, Kenwood DDX, Ford SYNC 1) advertise DivX/Xvid USB playback but choke on H.264 High Profile or HEVC.
• Lightweight portfolio reels for older Windows machines — DivX decodes on any Windows XP/7 box without installing modern codec packs, handy for archival client review stations.
• Camera roll archives — convert a shoot's worth of X3F frames into a single timestamped DivX slideshow as a quick-browse companion to the RAW archive.
• Real-estate and product walkarounds — a 480p DivX of 40 X3F stills runs under 30 MB and plays on the cheapest USB-equipped TV in a showroom.
• Cross-platform sharing without re-encode prompts — VLC, MPC-HC, and PotPlayer play DivX on Windows, macOS, and Linux without codec installation.

Frequently Asked Questions

Will my old DivX-Certified DVD player actually play the output?

Usually yes, provided you keep the output within the DivX Home Theatre profile boundaries: 480p/576p resolution, default bitrate, single audio stream, no Qpel or global motion compensation. Files encoded with advanced MPEG-4 ASP features that some encoders enable by default — Qpel, GMC, multiple B-frames, or files that exceed the video buffering verifier — may stutter or refuse to load on DivX Certified set-top hardware. Sticking to the Very High Constant Quality preset at 480p has the best historical compatibility track record.

Why does the slideshow look soft compared to opening the X3F in Sigma Photo Pro?

Two reasons. First, MPEG-4 ASP at typical bitrates (1–4 Mbps for 480p, 4–8 Mbps for 1080p) is lossy and uses YUV 4:2:0 chroma subsampling — so half the color resolution of the Foveon source is discarded at encode time. Second, X3F captures 12–14 bits per layer with full RGB at every photosite; DivX delivers 8 bits per channel with subsampled chroma. For pixel-accurate review, convert to a still format like PNG or TIFF instead.

Should I use DivX or Xvid for this slideshow?

Both encode the same standard — MPEG-4 Part 2 ASP — and most DivX Certified players accept both. DivX has the broader certification footprint on consumer DVD/Blu-ray hardware and head units; Xvid is open-source and slightly more aggressive with ASP features by default. If you specifically need playback on a sticker-certified device, pick .divx. If your target is software players or you want a smaller file at similar quality, see X3F to Xvid. For a modern container, X3F to MP4 and X3F to MKV are better choices.

My Foveon RAW is from a Quattro camera and contains separate top/middle/bottom layer data. Does that translate to the video?

No. The Quattro generation packs the top photodiode at full resolution and the middle/bottom layers at quarter resolution; Sigma's .x3i companion file holds the higher-res Super-Fine Detail mode if shot. The converter demosaics the X3F into a single RGB raster (the same way Sigma Photo Pro exports a TIFF) before feeding it to the video encoder. Multi-layer information is collapsed into one 8-bit YUV 4:2:0 frame.

Can I add audio — narration or background music — to the slideshow?

Not from this page in a single step. The Advanced Options expose merge strategy, image duration, background color, and resolution, but no audio track input. The fastest workflow is to render the silent .divx, then mux audio in a free tool like Avidemux or DivX Converter. Alternatively render to X3F to MP4 first and add audio in a video editor that handles AAC.

What frame rate does the output run at, and can I change it?

Frame rate is derived from your Image Duration setting. At the default 5 seconds per image the effective rate is 0.2 fps source, internally written at a standard container fps (typically 25 or 30 fps) with the same frame repeated. Pick 1/24 second to get a true 24 fps playback rate where each X3F frame shows for one screen refresh — useful if you're building a time-lapse from sequentially numbered Sigma stills.

Is there a maximum number of X3F files I can drop in?

Browser memory is the practical ceiling. X3F files from the SD Quattro H run 40–60 MB each, and the page decodes them in your tab — a 64-bit Chrome session typically handles 50–80 of them before slowing noticeably. For larger batches, convert in chunks of 25–40 frames and concatenate the resulting .divx segments in Avidemux or VirtualDub.

Are my X3F files uploaded to a server?

No. processing happens on our servers — the Foveon RAW is read, demosaiced, and encoded to MPEG-4 ASP locally, and only the finished .divx is offered for download. Closing the tab discards everything. There's no account, no watermark, and no retention.

Why pick DivX over a modern container like MP4 or WebM?

Only pick DivX when your target playback device specifically demands it — a 2005–2012 DVD player, an older car head unit, a hotel TV USB port, or an archival workstation locked to legacy codecs. For anything bought after about 2015, MP4 (H.264) plays more reliably, compresses better, and supports modern features like chapters and embedded subtitles natively. DivX exists in your toolkit for backward compatibility, not as a default.
