NEF is Nikon's RAW photo format — the unprocessed sensor data from a Nikon DSLR or mirrorless camera. MPG is a legacy video container holding MPEG-1 or MPEG-2 video, the codecs behind Video CD, DVD, and older broadcast gear. This converter renders the NEF to a single frame and holds it on screen for a duration you set, writing a short, silent, motionless MPG clip. It exists for one narrow purpose: feeding a still photo into a player or authoring system that only accepts legacy video. If you just want a viewable picture, use NEF to JPG; for a modern clip that plays on phones and the web, use NEF to MP4.
NEF Format at a Glance
| Property | Value |
|---|---|
| Full name | Nikon Electronic Format (Nikon's RAW) |
| Type | Camera raw still image — one photo per file |
| Structure | Built on a TIFF-style header (proprietary Nikon extension), not standard TIFF |
| Bit depth | 12-bit or 14-bit sensor data, depending on the camera (per Nikon) |
| Resolution | Matches the sensor — roughly 20-45 megapixels on recent Nikon D-series and Z-series bodies |
| Editing model | White balance, hue, tone and sharpening are kept as instruction sets, not baked into pixels (per Nikon) |
| Audio | None — it is a photo |
| Best for | Keeping the editable master of a shot before any rendering |
MPG Format at a Glance
| Property | Value |
|---|---|
| Full name | MPEG video stream (MPEG-1 / MPEG-2) |
| Standard | MPEG-1 = ISO/IEC 11172 (published 1993); MPEG-2 = ISO/IEC 13818 (published 1995) |
| Default codec here | MPEG-2 video with MP2 audio (MPEG-1 selectable for Video CD-era players) |
| Typical frame size | SD-class: SIF ~352×240 for MPEG-1; DVD 720×480 (NTSC) or 720×576 (PAL) for MPEG-2 |
| Motion | A NEF has no timeline, so the clip is one held frame — no pan, zoom, or transition |
| Audio | Silent — a photo carries no audio track |
| Native browser support | None — built for DVD players and legacy hardware, not phones or web browsers |
| Best for | DVD authoring, Video CD, and old institutional or broadcast playback systems |
How to Convert NEF to MPG
- Upload Your NEF File: Drag and drop your
.nefonto the page or click "+ Add Files" to browse. You can queue several Nikon photos at once. - Set the Image Duration: Under "Image Duration", choose how long the still is held — from a single frame (1/60s, 1/30s, 1/24s) up to 10 seconds, with 5 seconds as the default. This is the length of the resulting clip.
- Set Background Color and Quality: Pick a "Background Color" (black by default) to fill any letterbox bars and keep "Quality Preset" on "Very High (Recommended)". Under Advanced Options the "Video Codec" defaults to MPEG-2 — switch it to MPEG-1 only for the oldest Video CD-era players.
- Convert and Download: Click "Convert" and download your MPG. No sign-up, no watermark.
Frequently Asked Questions
Why would I convert a NEF photo to MPG instead of MP4?
Only when something downstream cannot read modern video. MPG carries MPEG-1 or MPEG-2 — the codecs behind Video CD, DVD, and older broadcast equipment, which predate H.264 by more than a decade. If you are feeding a DVD-authoring tool or an old institutional player, MPG (MPEG-2) is the safe match. For a phone, a website, or any current editor, NEF to MP4 produces a smaller, far more compatible clip. If you do not need video at all, NEF to JPG gives you a plain viewable image.
Does the MPG keep my Nikon photo's full resolution?
No. MPEG-1 targets roughly 352×240 (SIF) and MPEG-2 targets DVD-era frames like 720×480 or 720×576, so a 20-to-45-megapixel NEF is downscaled by a large factor to fit a standard-definition video frame. MPG is fundamentally an SD-era format — it cannot match the detail of the original photo or of an H.264 MP4 at full size. If pixel count matters, keep the NEF and export a full-resolution still with NEF to TIFF instead.
Do I lose the RAW editing latitude when I convert NEF to a video?
Yes. A NEF stores 12-bit or 14-bit sensor data with white balance, hue, tone and sharpening held as editable instruction sets rather than baked into the pixels, as Nikon describes. To write a video frame the converter must demosaic and develop the raw first — applying the current white balance, exposure and Picture Control and flattening the result to ordinary 8-bit video pixels. Once that frame is inside an MPG the latitude is gone, so keep the original .nef as your master and set the look in a RAW editor first.
Should I pick MPEG-1 or MPEG-2 for the MPG?
MPEG-2 is the default and the right choice for almost every MPG use — it is the DVD and digital-broadcast codec, with better quality at a given bitrate. Choose MPEG-1 only for a true Video CD or a very old player that cannot handle MPEG-2; it is the more constrained, lower-bitrate option and looks softer. You set this under "Video Codec" in Advanced Options, where the audio track defaults to MP2.
Why is my NEF-to-MPG clip silent, and how long is it?
It is silent because a photo contains no audio, so image-to-video conversion omits the audio track rather than padding it with silence. The length comes entirely from "Image Duration": set it to 5 seconds and the single rendered frame is held for 5 seconds. In our testing, one developed NEF held for 5 seconds and encoded as MPEG-2 produced a short, silent standard-definition clip suitable for a DVD-style timeline — add a soundtrack in an editor afterward if you need audio.
How are my files handled, and how long are they kept?
Your NEF 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. If the resulting clip is too large to send, run it through the video compressor first.
