DNG to AVI Converter

DNG to AVI Converter

DNG (Adobe Digital Negative) is an open RAW photo format: the unprocessed 12-to-16-bit sensor data a camera recorded, before white balance or exposure were applied. AVI (Audio Video Interleave) is Microsoft's RIFF-based video container from November 1992, the format that older Windows capture cards, editors, and archives were built around. Converting a DNG to an AVI renders the RAW photograph into ordinary video pixels and wraps it in that container, so one still becomes a silent, motionless clip held for a duration you choose — and several DNGs can be merged into a sequence instead. If you want a clip that plays everywhere rather than one a legacy Windows tool will accept, DNG to MP4 is the better target.

How to Convert DNG to AVI

1. Upload Your DNG Files: Drag and drop your .dng files onto the page or click "+ Add Files". You can queue several at once; RAW files are large, so the upload is usually slower than the encode.
2. Set Merge Strategy and Duration: Choose Merge images to put every uploaded photo into a single AVI, or Video per image for a separate file each. Then set Duration — how long one frame is held, from 1/60s up to 10 seconds, with 5 seconds per frame as the default.
3. Pick Background Color, Quality Preset, or Video Codec: Background Color (White by default) fills the letterbox bars when your photo's shape differs from the video frame. Leave Quality Preset on Very High (Recommended), or open Show All Options to change the Video Codec or set a Video resolution such as 1920 x 1080.
4. Convert and Download: Click "Convert" and download your AVI. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically a few hours later. No sign-up, no watermark.

What the Conversion Actually Produces

Two things about this conversion surprise people, and both follow from the formats themselves rather than from any setting.

The RAW render is one-way. A DNG holds mosaiced sensor data with real editing latitude — recoverable highlights, a white balance you can still change months later. To become video it has to be demosaiced into ordinary RGB pixels with the as-shot white balance and a standard tone curve baked in, so nothing inside the AVI is re-developable afterwards. Keep the original .dng as your master.

The output is a still, not footage. A single DNG produces one frame repeated for the duration you set: no pan, no zoom, no transitions, and no audio stream. Motion appears only when you upload several different photos and choose Merge images, in which case Duration doubles as the frame interval — 1/24s per frame gives a 24 fps sequence, while 5 seconds per frame gives a slideshow you can read.

Two details matter specifically for AVI. Background Color paints only the padding around a photo whose aspect ratio doesn't match the frame; it is a solid fill, never transparency, because the AVI written here carries no alpha channel. And under Show All Options the Video Codec default is MPEG-4 Part 2, the codec most likely to keep the file readable in the older Windows software people usually want an AVI for.

When AVI Is the Wrong Target

AVI earns its place when something specific demands it: an older Windows capture or editing workflow, a batch process that only accepts .avi, or a tool such as VirtualDub, which is still "mainly geared toward processing AVI files" on Windows. Outside those cases the container costs compatibility for nothing, since browsers don't play AVI natively and phone galleries and TV apps are inconsistent about it. For the same still clip in a container that plays almost anywhere, use DNG to MP4; if you never wanted a video at all and just need a viewable picture, DNG to JPG produces a far smaller file. And for a genuine CinemaDNG frame sequence — Adobe's motion-picture RAW variant — use a RAW-aware editor such as DaVinci Resolve, which reads the frame ordering and timing metadata that a still-image converter has no way to interpret.

Frequently Asked Questions

Which video codec does the AVI output use, and can I change it?

MPEG-4 Part 2 (ISO/IEC 14496-2) by default. AVI is only a container, so it has to carry an encoded video stream, and MPEG-4 Part 2 is the pairing that older Windows software is most likely to decode. Under Show All Options the Video Codec dropdown also offers Xvid, DivX, MS MPEG-4, MPEG-1, MPEG-2, MJPEG, H.263, and HuffYUV, alongside modern codecs like H.264 and VP9. Two useful picks: HuffYUV if you want a lossless frame with no compression artifacts (expect a very large file), and MJPEG if a legacy editor chokes on MPEG-4. Selecting H.264 or VP9 inside an AVI does work, but anything able to decode them will also play an MP4.

Does the AVI keep the RAW editing latitude of my DNG?

No. A DNG stores 12-to-16-bit mosaiced sensor data, which is why highlights, shadows, and white balance stay adjustable long after the shot. The AVI stores a finished 8-bit video frame: the demosaic, the as-shot white balance, and a standard tone curve are already applied and cannot be undone. The picture can look excellent at the Very High preset, but it is a delivery file, not a negative — keep the .dng if you may still want to develop it.

Why is the AVI silent, and can I add sound later?

Because the source is a photograph. Our pipeline produces a single video stream and no audio stream at all for image-to-video jobs — the Audio Codec control is hidden for image inputs because there is nothing to encode. That is not a fault in the file: it is a valid AVI with one video track. Any editor will let you lay music or narration under the clip afterwards, and the silent AVI imports normally.

Can I turn a sequence of DNG frames into a real moving AVI?

For an ordinary batch of stills, yes: upload every frame, choose Merge images, and set Duration to the inverse of the frame rate you want (1/24s per frame for 24 fps, 1/30s for 30 fps). Frames are stitched in the order they were added, so name them sequentially — IMG_0001, IMG_0002 — before uploading. What this page cannot do is interpret a CinemaDNG clip's own frame-rate and timing metadata; for drone or cinema RAW footage, open the sequence in a RAW-aware editor and export from its timeline.

Why does my photo have white bars around it in the AVI?

Because the photo's aspect ratio doesn't match the output frame, so the difference is padded with the Background Color — white unless you change it — instead of stretching or cropping your picture. Pick a different color, or set a Video resolution under Show All Options that matches your photo's shape. The padding is always a solid color: the AVI written here has no alpha channel, so those bars cannot be made transparent.

Will an AVI play in a browser, on a phone, or on a smart TV?

In a browser, no. MDN's container guide lists MP4, WebM, and Ogg as the containers browsers support natively, and AVI is not among them, so an .avi linked on a web page downloads rather than plays. On desktops it is safe — VLC and anything built on ffmpeg open AVI without complaint, as do most Windows editors. Phones and smart TVs are the unreliable middle ground: many gallery apps and TV media players refuse AVI outright, which is the main reason to send those files to MP4 instead.

Is AVI still a maintained format, or is it frozen?

Effectively frozen — and for a legacy workflow that is the appeal. Microsoft still publishes the AVI RIFF file reference, but it now sits under DirectShow, which Microsoft itself flags as a legacy feature superseded by Media Foundation. The significant extension to the format was the OpenDML "AVI 2.0" set, which added the indx super-index so files could grow past the original index's limits. Nothing new is coming, which is exactly why decades-old software still reads AVI reliably. For anything forward-looking, MP4 is the maintained choice.

How are my DNG files handled during conversion, and how long are they kept?

Files are uploaded over an encrypted connection, rendered and packaged into AVI on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The practical limit when converting a long RAW sequence is upload size and time rather than the encode, since DNG files often run to tens of megabytes each.
