ARW to MPEG Converter

ARW to MPEG Converter

An ARW is one Sony Alpha raw photograph; a .mpeg file is an MPEG program stream, the DVD-era packaging for MPEG-1 and MPEG-2 video. This converter renders the raw to ordinary pixels and holds that single frame on screen as a short, silent clip inside that stream — a title card, a slate, a slideshow segment. Nothing moves, because a photograph has no timeline, and there is no sound, because a still carries none. Below is what each format actually is, which of the two codecs to pick, and when a video is simply the wrong answer to your problem.

How to Convert ARW to MPEG

1. Upload Your ARW File: Drag and drop your Sony .arw onto the page or click "+ Add Files" to browse. Several raw frames can be queued and converted in one batch.
2. Set Merge Strategy and Image Duration: "Merge strategy" chooses "Merge images" (all uploads become one continuous clip) or "Video per image" (a separate .mpeg each). "Image Duration" runs from a single frame at 60fps up to 10 seconds per frame, with 5 seconds per frame pre-selected.
3. Pick a Video Codec, Quality Preset, and Video Resolution: "Video Codec" offers MPEG-2 and MPEG-1, with MPEG-2 pre-selected. "Quality Preset" sits at Very High (Recommended), and "Video resolution" can stay on "Keep original" or take a fixed size such as 1920 x 1080. "Background Color" (White by default) pads any letterbox area.
4. Convert and Download: Click Convert and download the .mpeg. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.

MPEG-2 or MPEG-1?

• MPEG-2 is the default and the right answer nearly always. It is the codec DVD-Video is built on, so disc-authoring tools, older broadcast systems, and hardware players expect it, and it handles a full-resolution frame far more efficiently than its predecessor.
• MPEG-1 exists for genuinely old targets — early CD-video style pipelines and software that predates DVD. It is more compatible with antique decoders and noticeably weaker at anything above modest resolutions, so a detailed photograph shows compression artefacts sooner.
• Whichever you pick, the frame is 8-bit. Your raw's 12- or 14-bit latitude is spent at the render step, before the encoder ever sees the picture.

When a Video Is the Wrong Answer

If your goal is to look at, print, share, or re-edit the photograph, wrapping it in a video stream costs you resolution and quality for nothing: a single-frame MPEG is larger than the equivalent still and cannot be opened by an image editor. Convert ARW to JPG for a universal picture, or ARW to TIFF for a lossless, high-bit-depth editing master. ARW to MPEG earns its place only when something downstream genuinely wants program-stream MPEG — a DVD authoring project, a legacy broadcast ingest, an editor that will not take modern containers. For a clip that just needs to play on phones and the web, ARW to MP4 is the better target.

Frequently Asked Questions

Will the MPEG have any sound?

No. An ARW is a photograph and carries no audio, so there is nothing to encode and the Audio Codec menu is hidden for image sources — the output is a video-only program stream. That is not a limitation of MPEG, which carries audio perfectly well in other contexts; it is simply that the source has none. If the clip needs music or narration, add it on a timeline in a video editor after conversion.

Which codec does the .mpeg output use?

MPEG-2 by default, with MPEG-1 as the only alternative on this page. MPEG-2 video is the standard published jointly as ITU-T H.262 and ISO/IEC 13818-2 — the same video coding used for DVD-Video and for a generation of digital broadcast. MPEG-1 is the earlier, simpler standard and is worth choosing only when a very old decoder demands it, because it compresses a detailed photographic frame far less efficiently.

Why does my photo look worse as a video than it did as a raw?

Two separate losses stack up. First, the raw is demosaiced and tone-mapped to become a picture at all, which bakes in white balance, exposure, and colour and spends the 12- or 14-bit latitude that made it worth shooting raw. Second, the frame is scaled to video dimensions and encoded at 8 bits per channel with lossy compression, so smooth skies and gradients are where banding shows up first. Raising the Quality Preset reduces the second loss; nothing recovers the first.

How long is the clip, and how do I make it longer?

Image Duration controls it: the dropdown runs from a single frame at 60fps up to 10 seconds per frame, and 5 seconds per frame is pre-selected. One photograph at the default gives a five-second clip. With "Merge images" selected under Merge strategy, every uploaded ARW is held for that same duration and they play back to back, so the total length is the duration multiplied by the number of files. "Video per image" gives you one .mpeg per photograph instead.

Is this the same thing as an MPEG transport stream or an .mp4?

No, though the names overlap confusingly. A .mpeg file here is a program stream, designed for storage and local playback; a transport stream — .ts, .m2ts, .mts — is the broadcast and disc-oriented packaging built for error resilience, and MP4 is a different container entirely from the ISO base media file format family. They can all carry similar video, but players and authoring tools are fussy about which one they accept, so match the extension your pipeline asked for rather than assuming they are interchangeable.

Why is my photo letterboxed with white bars?

Because your camera's frame shape does not match the video frame it is being placed in. A 3:2 Sony still inside a 16:9 output leaves a gap on two sides, and that gap is filled with the Background Color setting, which defaults to White and can be set to any colour in the list. Leaving Video resolution on "Keep original" avoids the mismatch entirely in most cases; picking a fixed 1920 x 1080 reintroduces it.

Can I put several photos into one MPEG as a slideshow?

Yes, within limits. Upload as many ARW files as you want, leave "Merge strategy" on "Merge images", and each photograph is shown in turn for the Image Duration you chose, producing a single continuous clip. What you will not get is transitions: there is no cross-fade, pan, or zoom between frames, just a cut from one still to the next. For anything with motion design, generate the clip here and treat it as raw material in an editor.

What happens to my ARW file after the conversion?

It is uploaded over an encrypted connection, rendered and multiplexed into the program stream on our servers, and deleted automatically a few hours later — no sign-up, no watermark, never shared or made public. Only the file you download persists. Note that MPEG-2 spends a lot of bits on a full-resolution static frame, so a long duration at high quality produces a surprisingly large file for a single photograph; shortening the duration is the quickest way to shrink it.
