DNG to AVCHD Converter

DNG to AVCHD Converter

DNG (Adobe Digital Negative) is a raw still-photo format — one high-bit-depth image straight off a camera sensor. AVCHD is a consumer HD camcorder video format. So this conversion turns a single raw photo into a short, silent HD video clip that simply displays that image. It is a real conversion, but an unusual target: read the mismatch below before you pick it, because for most uses a plain photo (DNG to JPG) or a more compatible clip (DNG to MP4) is the better choice.

How to Convert DNG to AVCHD

1. Upload Your DNG File: Drag and drop your raw photo or click "+ Add Files." You can upload several DNGs at once; files travel over an encrypted connection and are deleted automatically from our servers after a few hours.
2. Set Merge Strategy and Duration: Use Merge images to combine multiple DNGs into one clip, or Video per image for a separate file each. The Duration dropdown sets how many seconds each photo is held on screen.
3. Pick Quality, Resolution and Background (Optional): Choose a Quality Preset (default Very High), set Video resolution to Keep original or a Fixed Resolution like 1920×1080, and set a Background Color for any area the photo doesn't fill.
4. Convert and Download: Click "Convert" and download your .mts file. No sign-up, no watermark.

Why This Conversion Is a Mismatch — Read First

• A raw photo becomes a silent clip. There is no audio in a DNG, so the output has no sound. AVCHD normally carries AC-3 or LPCM audio; here that audio track is simply absent.
• The .mts file is not an AVCHD disc. Camcorders and Blu-ray players expect the full BDMV/AVCHD folder structure (a BDMV or PRIVATE/AVCHD directory tree), not a loose .mts file. A bare .mts plays fine in VLC and most desktop editors, but won't be recognized as a disc by a player that scans for that structure.
• Raw latitude is baked down to 8-bit. AVCHD's H.264 stream is 8-bit; the 12–16-bit headroom that makes DNG worth keeping is flattened during encoding. Do your white-balance and exposure edits on the DNG first — once it's video, that flexibility is gone.
• AVCHD is a strict spec. It expects specific resolutions and frame rates and AC-3/LPCM audio, so it's a poor general-purpose container. If you just want a shareable clip of an image, DNG to MP4 plays on virtually every phone, browser, and social platform with far less fuss.

Frequently Asked Questions

Will my DNG to AVCHD clip have sound?

No. A DNG is a still photo with no audio, so the resulting clip is silent. AVCHD can carry Dolby AC-3 or LPCM audio when it comes from a camcorder, but there's nothing to encode from a raw photo, so the output has no audio track.

Does the output play on a camcorder or Blu-ray player as a real AVCHD disc?

Not on its own. AVCHD playback on hardware players relies on the full BDMV/AVCHD directory structure that camcorders write to a card or disc. The converter produces a standalone .mts file, which opens in VLC, desktop editors, and most media players, but a player that scans for the AVCHD folder tree won't see a loose file as a disc.

Should I convert DNG to AVCHD or to MP4?

For almost everyone, MP4 is the better target. It uses the same H.264 video but in a universally supported container that plays in every modern browser, on phones, and across social platforms. Choose DNG to MP4 unless you specifically need a .mts file for an AVCHD-based editing or archival workflow.

What if I just want a normal viewable photo, not a video?

Then don't convert to a video format at all. Use DNG to JPG for a small, universally viewable image, or DNG to PNG if you need lossless quality. Both produce a real photo you can open and share anywhere, instead of a clip that only shows the image.

Why is AVCHD limited to 8-bit when my DNG is 12 or 16-bit?

AVCHD's H.264 stream is encoded at 8 bits per channel by the consumer spec, while raw DNG files keep 12–16 bits of sensor data. That extra depth is what lets you recover highlights and push shadows. Once the photo is encoded to AVCHD, that latitude is baked in, so make any exposure and color edits on the DNG before converting.

Can I combine several DNG photos into one AVCHD clip?

Yes. Choose Merge images under Merge strategy and the converter chains your uploaded DNGs into a single clip, holding each photo on screen for the number of seconds set by the Duration control before cutting to the next. Choose Video per image instead to get a separate .mts file for each photo. The result is a sequence of held stills — not a cross-faded slideshow — and it stays silent, since none of the photos carries audio. Add any music or transitions on your editing timeline after import.

How large is the AVCHD file from a single DNG?

In our testing, a single full-resolution DNG held for 5 seconds at the Very High preset produced an .mts clip only a few megabytes in size, because a motionless H.264 frame compresses heavily — there is no frame-to-frame motion for the encoder to spend bits on. Longer durations and higher resolutions raise that figure modestly, but a still-image AVCHD clip is far smaller than a comparable stretch of real camcorder footage.

Are my uploaded DNG 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, and nothing is shared or made public. Because DNGs are large, the practical limit you'll hit is upload size and time rather than anything on the conversion side.
