CRW to AVI Converter

CRW to AVI Converter

CRW is Canon's original digital RAW format — the unprocessed sensor file written by its earliest DSLRs and prosumer compacts in the early 2000s, stored in Canon's own CIFF container rather than the TIFF-based formats that came later. AVI (Audio Video Interleave) is Microsoft's video container, introduced with Video for Windows in 1992. This is an unusual pairing: a still photograph going into a video wrapper. The result is one motionless frame, held on screen for a duration you set, with no audio — useful when an older Windows editor or timeline expects an .avi slate, but for most people the picture or a modern clip is the better target.

What the CRW-to-AVI Conversion Actually Does

Two one-way things happen here, and both are easy to miss with a RAW source:

• The RAW is rendered first. A CRW holds 10–12-bit linear sensor data with editing latitude — you can recover highlights and shift white balance long after the shot. To put it into a video, that data is demosaiced into ordinary RGB pixels and the current white balance and exposure are baked in. The latitude does not survive into the AVI, so render once and keep the original .crw as your master.
• The output is one frame held still, not a clip. From a single CRW the AVI shows your photo as a steady image for the duration you set — no panning, zoom, transition, or audio track. Because the source is a photo, there is no motion to extract; setting "Duration" to 5 seconds simply presents the same frame for 5 seconds.

How to Convert CRW to AVI

1. Upload Your CRW File: Drag and drop your Canon .crw file onto the page or click "+ Add Files" to browse. Any companion .thm thumbnails are harmless if included, and you can queue a batch from an EOS D30, D60, 10D, 300D, or PowerShot G/Pro/S folder at once.
2. Set Duration and Merge strategy: Open Advanced Options. Use "Duration" to control how long the still shows — from a single frame (1/60s) up to 10 seconds per frame, with 5 seconds per frame the default — and use "Merge strategy" to pick "Merge images" (combine several photos into one AVI) or "Video per image" (a separate file per photo).
3. Pick Quality Preset and Background Color (Optional): Keep the "Preset" on "Very High (Recommended)", and set a "Background Color" (Black by default) to fill any letterbox bars where the photo's shape doesn't match the output frame. Under "Show All Options" the "Video Codec" defaults to MPEG-4, the codec this converter pairs with AVI.
4. Convert and Download: Click "Convert" and download your AVI. No sign-up, no watermark.

Frequently Asked Questions

Which Canon cameras actually wrote CRW files?

CRW shipped with Canon's first DSLRs and the matching prosumer compacts of the era: EOS D30 (2000), D60 (2002), 10D (2003), and 300D / Digital Rebel (2003), plus the PowerShot Pro1, G1, G2, G3, G5, G6, and the S30, S40, S45, S50, S60, S70. With the EOS-1D Mark II in 2004 Canon switched to the TIFF-based CR2 format, and CR3 followed in 2018 — three RAW generations in all, as documented in the exiftool CRW format reference.

Does the AVI have any motion or sound?

No. From a single CRW, the conversion renders your photo and displays it as one static frame for the duration you set. There is no panning, zoom, or animation, and the output carries no audio track — for an image source the "Audio Codec" option does not even appear. If you upload several photos and choose "Merge images," they play back to back, but each frame is still a static image shown for its set duration, with no transitions between them.

Which video codec does the AVI output use?

MPEG-4 by default. AVI is a container, not a codec, so it has to carry an encoded video stream inside it; for AVI output this converter defaults to MPEG-4 Part 2 — the same MPEG-4 ASP family popularized by DivX and Xvid that AVI files have long carried. You can change it under "Show All Options" via the "Video Codec" dropdown, which lists other AVI-compatible choices. Because the source is a still photo, no audio stream is added.

Do I lose the RAW editing latitude when I convert CRW to AVI?

Yes. A CRW stores 10–12-bit linear sensor data, which is why you can recover highlights, shadows, and white balance long after the shot. To put the photo into a video, the converter renders it first — demosaicing the sensor data and baking in white balance, exposure, and tone. Once that rendered frame is inside the AVI, the latitude is gone, exactly as it would be in a JPEG. Keep your original .crw if you may still want to edit it in Lightroom or Canon's Digital Photo Professional.

Should I convert CRW to AVI, JPG, or MP4?

Choose by where the file will go. AVI dates to 1992 and is a legacy Microsoft container, so it makes sense only when a specific older tool, Windows editing workflow, or archive process expects that exact container. If you only want a viewable, shareable picture — which is what most people with old CRW files actually need — convert to an image with CRW to JPG and keep the .crw as your editable master; it is far smaller and opens everywhere. If you want a video clip that plays on the widest range of phones and browsers, CRW to MP4 is the safer video target than AVI.

How are my files handled during conversion?

In our testing, a single full-resolution CRW from a 6 MP Canon DSLR, held for 5 seconds at the "Very High" preset, produced a small AVI, since a motionless MPEG-4 frame compresses heavily. Your file is 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 main practical limit is upload size and time, since CRW files can run several megabytes each, not your device.
