ORF to MPG Converter
ORF is the Olympus RAW Format — a single, high-bit-depth still written straight off an Olympus or OM System camera sensor. MPG is the legacy MPEG program-stream video container. This converter renders one ORF photo into a short, silent MPG clip that holds the still on screen for a duration you choose. It is a genuinely niche conversion: if you only want a viewable picture, convert the ORF to a still image instead — MPG makes sense only when a player, kiosk, or DVD-authoring workflow specifically needs a video file.
ORF Format at a Glance
| Property | Value |
|---|---|
| Full name | Olympus RAW Format |
| Used by | Olympus and OM System digital cameras |
| Container | TIFF/EP-based binary structure (proprietary) |
| Holds | A single still photo — unprocessed sensor data, not video |
| Bit depth | 12, 14, or more bits per pixel per channel of sensor data |
| Editing latitude | High: white balance, exposure, and highlight recovery can be re-developed |
| Editor support | OM Workspace / Olympus Viewer, Lightroom, Photoshop / Camera Raw, Capture One, GIMP |
| Best for | Editing and archiving Olympus captures before exporting a finished image |
MPG Format at a Glance
| Property | Value |
|---|---|
| Full name | MPEG program stream (the .mpg container) |
| Standard | ISO/IEC 11172 (MPEG-1, 1993) and ISO/IEC 13818 (MPEG-2) |
| Video codec here | MPEG-2 by default on this converter |
| Audio | MPEG-1 Audio Layer II (MP2) when present — but a photo source produces a silent clip |
| Bit depth | 8 bits per channel |
| Best for | DVD-era authoring, set-top boxes, and legacy players that predate H.264 |
| Modern alternative | H.264 in MP4 — smaller, sharper, far more compatible |
How to Convert ORF to MPG
- Upload Your ORF File: Drag and drop your
.orfphoto onto the page or click "+ Add Files" to browse. You can queue several Olympus RAW files at once. - Set the Duration: Under "Duration", choose how long the still is held on screen — the dropdown defaults to "5 seconds per frame" and ranges from a single short frame up to 10 seconds. This sets the length of the resulting clip.
- Set the Preset, Resolution, and Background Color: Keep the "Preset" on "Very High (Recommended)"; leave "Video resolution" on "Keep original" or pick a Fixed or Preset resolution; and set a "Background Color" (White by default) to fill any letterbox bars left when the photo's aspect ratio doesn't match the frame.
- Convert and Download: Click "Convert" and download your MPG. No sign-up, no watermark.
Frequently Asked Questions
What does converting an ORF photo to MPG actually produce?
A short, silent video that shows your single ORF photo as a still frame for the duration you set. There is no motion and no sound — the converter demosaics and tone-maps the RAW into one ordinary video frame and holds it. If your goal is a picture you can view, print, or post, this is the wrong format; convert to ORF to JPG or ORF to TIFF instead. Choose MPG only when something downstream genuinely needs a .mpg file.
Why is the MPG clip silent?
An ORF holds a photo, and a photo carries no sound, so this image-to-video conversion writes no audio track rather than padding the clip with silence. The MPG is silent in every case. If you need a soundtrack, open the clip in a video editor afterward and add music or narration.
Does the MPG keep my ORF photo's full resolution and bit depth?
No. An ORF stores 12, 14, or more bits per pixel per channel of sensor data with wide editing latitude. To make a video frame, that data is demosaiced and tone-mapped down to an ordinary 8-bit MPEG frame, and a high-megapixel image is scaled to fit the chosen resolution. The video is a rendered, baked-in interpretation — it does not preserve the highlight recovery or detail of the original RAW. Keep the .orf as your master.
Should I use MPG or MP4 for an ORF-derived clip?
MP4 (H.264) for almost everything. The .mpg output here carries MPEG-2, a 1990s codec built for DVDs and set-top boxes — larger files, softer image, and patchy support on modern phones and browsers. Choose ORF to MP4 for sharing, editing, or web use, and reserve MPG for a player or DVD-authoring tool that specifically requires that container.
What if I just want to view or edit the ORF, not make a video?
Then skip the video wrapper entirely. Convert to ORF to JPG for a small, universally openable image, or to ORF to TIFF for a high-fidelity, print-ready master that keeps more detail. ORF itself opens in OM Workspace, recent Lightroom and Camera Raw releases, Capture One, and GIMP — the video route is only for the rare case where you genuinely need an .mpg file.
Why is the converted clip larger than the original photo, and what can I do about it?
MPEG-2 is an older, low-efficiency codec, and holding a still for several seconds at video bitrates can produce a file bigger than the source photo. In our testing, a single ORF held for 5 seconds and encoded as MPG produced a short standard-definition clip noticeably heavier than the same image saved as a high-quality JPG. Shorten the "Duration", or if the file needs to be smaller still, run the result through the video compressor.
Can I burn the resulting MPG straight onto a DVD?
Not on its own. Even though the clip carries DVD-era MPEG-2 video, a playable DVD needs the full VIDEO_TS folder — the IFO and BUP navigation files alongside the video objects — which only DVD-authoring software builds. Treat this .mpg as a source clip you import into your authoring tool, where it becomes a slide, menu background, or intro before the disc is burned.
What resolution and frame rate does the MPG use?
The clip keeps your photo's original proportions unless you pick a Fixed or Preset resolution under "Video resolution", and the single still is simply repeated at a standard video frame rate for the whole duration. If you are authoring for a disc, set a DVD size — 720×480 for NTSC (North America, Japan) or 720×576 for PAL (most of Europe and Australia) — so your authoring software doesn't rescale or letterbox the frame.
How are my files handled, and how long are they kept?
Your ORF is uploaded over an encrypted connection, rendered on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, and your photos are never shared or made public.
