PEF to DivX Converter

PEF to DivX Converter

PEF is Pentax's proprietary camera raw format — a single, unprocessed still photo straight off a Pentax DSLR sensor. DivX is a video format. So this is not a normal image conversion: it takes one PEF photo and renders it as a short, silent DivX video clip that simply holds that one picture on screen for a set number of seconds. It does not animate or add sound. If you actually want a viewable photo, convert PEF to JPG instead; if you want a shareable clip that plays on modern devices, PEF to MP4 is the better target (more on why below).

How to Convert PEF to DivX

1. Upload Your PEF File: Drag and drop your Pentax .pef photo, or click "+ Add Files". You can upload several PEFs; use the Merge strategy control to make one combined clip ("Merge images") or a separate clip per photo ("Video per image").
2. Set Image Duration and Background Color: Image Duration controls how long the still is held on screen (default is 5 seconds per frame). Background Color (default Black) fills any area around the photo when its aspect ratio doesn't match the video frame.
3. Pick Resolution and Quality (Optional): Under Video resolution choose Keep original, a Preset Resolution (e.g. 1080p / 768p), or a custom Width × Height. The Quality Preset defaults to "Very High (Recommended)"; lower it only to shrink the file.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

What This Conversion Actually Does (and Its Limits)

Because PEF is a raw photo and DivX is video, the converter is effectively building a one-slide slideshow. Worth knowing before you run it:

• It's silent. There is no audio track — a still image has no sound, so the output is a muted clip.
• Raw latitude is baked down. PEF carries 12- or 14-bit sensor data with wide highlight/shadow latitude meant for editing. The DivX output is ordinary 8-bit video; the editing headroom of the raw is gone once it's rendered.
• DivX is a dated codec. MPEG-4 Part 2 ASP predates H.264 by years and is far less efficient. For anything you want to share, post, or play on a phone, PEF to MP4 (H.264) is more universal and smaller at the same quality. Choose DivX mainly to feed an older DVD/Blu-ray player or a workflow that specifically expects an AVI/DivX file.
• For a normal photo, don't convert to video at all. If your goal is just to view or share the picture, use PEF to JPG or PEF to TIFF. Convert to DivX only when you genuinely need a video container.

Frequently Asked Questions

Does the DivX clip have sound?

No. A PEF file is a single photo with no audio, so the resulting DivX video is silent. The converter simply holds your image on screen for the Image Duration you set. There's nothing to un-mute — adding a soundtrack would require a separate video-editing step after download.

Why would I convert a raw photo to DivX video instead of an image?

In most cases you wouldn't. Converting PEF to DivX makes sense only when something downstream specifically expects a video file — for example feeding a single image into an older DVD/Blu-ray authoring tool or a legacy player that reads AVI/DivX. If you just want to look at, edit, or share the photo, PEF to JPG (universal viewing) or PEF to TIFF (lossless editing master) is the right conversion.

Should I use DivX or MP4 for the clip?

MP4 for almost everyone. DivX uses the MPEG-4 Part 2 codec, which dates to the early 2000s and has largely been replaced by H.264 and H.265. An H.264 MP4 plays natively on phones, browsers, and modern TVs and is typically smaller at the same quality. Pick DivX only for compatibility with older hardware that needs an AVI-family file. For the modern path, use PEF to MP4.

Will I lose image quality going from PEF to DivX?

Yes, in two ways. First, PEF's 12- or 14-bit raw data with wide editing latitude is rendered down to standard 8-bit video, so the post-processing headroom of the raw is gone. Second, DivX is a lossy MPEG-4 Part 2 codec, so the rendered frame is compressed. In our testing, a single Pentax PEF held for 5 seconds at the "Very High" preset produced a small silent clip of only a few hundred kilobytes — fine for playback, but not an archival master. Keep the original PEF if you want to re-edit later.

Can I make the photo show for longer or combine several PEFs?

Yes. The Image Duration control sets how many seconds the still is displayed, from a single frame up to several seconds. If you upload multiple PEF files, the Merge strategy control lets you either combine them into one continuous slideshow clip ("Merge images") or output a separate DivX file for each photo ("Video per image").

Are my PEF files kept private?

Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There's no sign-up, no watermark on the output, and your files are never shared or made public. If you'd rather not convert a raw at all, you can extract a standard image first with PEF to JPG.

What software or device plays a .divx file?

DivX video (MPEG-4 Part 2) plays in VLC and Media Player Classic on the desktop, and in many standalone DVD/Blu-ray players and older "DivX Certified" smart TVs — which is the main reason to target it. Modern web browsers and default OS players often will not open a raw .divx file. For playback that works almost anywhere, an H.264 MP4 is safer — PEF to MP4.

Is a .divx file the same as Xvid or AVI?

They are closely related. DivX and Xvid are two different encoders that both implement the MPEG-4 Part 2 Advanced Simple Profile codec, so their streams are broadly interchangeable. The .divx container is itself an extension of Microsoft's AVI format, so many players and tools treat a .divx file much like an .avi. This conversion writes MPEG-4 Part 2 video into that AVI-family container.
