PEF to WMV Converter

PEF to WMV Converter

PEF is Pentax's proprietary RAW photo format — the unprocessed sensor data a Pentax DSLR writes to the card. WMV (Windows Media Video) is a legacy Microsoft video format, not an image format, so this conversion does two unusual things at once: it freezes a still photo into a video clip, and it aims that clip at a Windows-only codec. The result is a short, silent WMV that holds your rendered photo on screen for a duration you choose. This pairing is niche — if you just want a viewable photo, convert PEF to JPG; if you need a still as a clip that plays everywhere, PEF to MP4 is far more compatible. Choose WMV only when a specific Windows Media workflow demands the .wmv extension.

How to Convert PEF to WMV

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

Frequently Asked Questions

Should I really convert PEF to WMV, or to JPG or MP4 instead?

For almost every purpose, no. A PEF is a high-quality RAW still and WMV is a legacy Microsoft video codec, so this pairing mismatches twice — still-into-video and archival-photo-into-consumer-video. To view, print, or share the photo, convert PEF to JPG. If you genuinely need the photo as a playable clip, PEF to MP4 produces an H.264 file that plays on phones, browsers, and modern editors. Pick WMV only when a Windows Media Player, Windows Movie Maker, or Windows-only application insists on the .wmv extension.

Does converting a single PEF to WMV create any motion?

No. A PEF is one still photograph with no motion data, 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 PEF files merged into one clip; even then there are no transitions, just each photo shown in turn.

Why does my PEF-to-WMV output have no sound?

Because a still photo contains no audio data, so the WMV is video-only by design. A .wmv can carry a WMA audio stream, but a single PEF has nothing to fill it, so the converter writes no audio track. If you want music or narration, convert first, then add an audio track in any video editor.

Which codec does the WMV output use?

The video defaults to WMV 2 — the FourCC for Windows Media Video 8 — inside an ASF container, the standard convention for a .wmv file. Under the Video Codec menu you can switch to WMV 1 (Windows Media Video 7) for an older target. These are distinct from WMV 9, which Microsoft submitted to SMPTE and which was approved in March 2006 as SMPTE 421M, better known as VC-1. Because the source is a single still, no audio codec is offered and the clip is silent.

Will I lose image quality going from RAW PEF to WMV?

Yes, substantially, and that is inherent to the conversion. A PEF holds 12-bit or 14-bit unprocessed sensor data that must be demosaiced to become viewable; that render bakes in white balance, exposure, and tone — the editing latitude that is the whole reason to shoot RAW. A 20-40 MP Pentax frame is then scaled to a standard-definition-to-1080p WMV frame, discarding most of the resolution, and WMV 2 is an older lossy codec. Keep the original PEF as your master; treat the WMV as a one-off delivery file.

Is PEF still maintained, or should I be shooting DNG?

PEF is a TIFF/EP-based RAW format Pentax has used since the mid-2000s, but Pentax (now Ricoh Imaging) also lets most bodies shoot Adobe's open, royalty-free DNG straight in-camera — so you can pick either at capture. PEF is slightly smaller and Pentax-native; DNG is broadly supported by third-party tools without a libraw update and is the safer long-term archive. This converter reads PEF directly; if you shoot DNG, see DNG to WMV for the identical workflow.

What happens to my uploaded PEF 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. In our testing, a single 24-megapixel PEF held for 5 seconds at the Very High preset produced a short, silent WMV of roughly 1-3 MB, since one repeated frame compresses efficiently.
