CR2 to OGV Converter

CR2 to OGV: Theora or VP8?

An .ogv is an Ogg bitstream carrying video, registered by the IETF as the video/ogg media type in RFC 5334 back in September 2008. Turning a Canon raw into one means rendering the photograph and encoding it as a clip that is held on screen for a duration you choose. The choice that actually matters here is the codec inside: VP8, which is preselected, or Theora, which is the codec the Ogg video type was originally registered around. Both are royalty-free and openly published, so the decision comes down to what is going to open the file.

Theora vs VP8 Inside an Ogg File

When to Pick Theora

• Something on the receiving end expects a classically-formed .ogv, which historically meant Theora video with Vorbis audio.
• You are feeding older free-software tooling or a long-standing Ogg-based pipeline that was built before VP8 existed.
• The requirement you were handed literally says Theora, which happens in academic, archival and public-sector specifications that were written around Xiph formats.

When to Pick VP8

• You want the smaller file at the same visual quality, which VP8 gives you almost always.
• The clip is destined for a web page, where VP8 is the codec browsers have been decoding for over a decade.
• You have no specific requirement — it is preselected, and it is the more capable of the two.

How to Convert CR2 to OGV

1. Upload Your CR2 File: Drag your .cr2 onto the page or click "+ Add Files". With several queued, Merge strategy picks between one combined clip ("Merge images") and one file per photograph ("Video per image").
2. Choose the Video Codec: Video Codec offers VP8, which is preselected, and Theora. Audio Codec lists Vorbis, Opus, Speex and FLAC — the Xiph family Ogg was built for — though a photograph has nothing to encode into them.
3. Set Duration, Resolution and Quality: Image Duration holds the picture for anything from 1/60 of a second up to 10 seconds, starting at 5. Video resolution starts on "Keep original"; Fixed Resolutions or Width x Height in Pixels give an exact raster, with Background Color (white by default) filling any bars that creates. File Compression starts on the "Very High (Recommended)" Quality Preset.
4. Convert and Download: Click Convert and save the .ogv. It is uploaded over an encrypted connection, converted on our servers and deleted automatically a few hours later — no sign-up, no watermark.

OGV Compared With the Modern Alternatives

Frequently Asked Questions

Why is VP8 the default rather than Theora?

Because it is the better codec of the two and is decoded by every current browser. Theora's bitstream was frozen in 2004 and it is directly derived from On2's VP3, so it carries the efficiency of that era; VP8 came later, was documented by the IETF as RFC 6386, and produces noticeably smaller files at the same quality. Theora remains one click away for the cases that genuinely need it.

Does an .ogv with VP8 in it still count as a proper Ogg file?

Yes. Ogg is a container and is agnostic about what it transports, and VP8 in Ogg is a combination current browsers handle. It is worth knowing that the video/ogg registration in RFC 5334 predates VP8 and names Theora and Dirac in its list of video codecs, so a very old or very strict Ogg tool may expect Theora specifically. If you are handing the file to something ancient, switch the codec.

Should I use OGV at all, or WebM instead?

For the open web, WebM is the more sensible default — Mozilla's own container guidance is that Ogg never gained the breadth of support that would make it a first choice, and that you are typically better off with WebM unless you need to reach very old browser versions. Ogg is the right answer when a specification, an institution or an existing pipeline asks for it by name. If the web is your target, CR2 to WebM is the direct route.

Why does the clip run at one frame per second?

Because a photograph has no motion to sample. The picture is encoded once, looped, and stopped after the duration you set, so a five-second clip is five identical frames. Any editor will re-time it to a conventional rate if something downstream wants one, and re-encoding identical frames costs almost nothing.

Why is there no sound in the file?

There is nothing to encode. A still image carries no audio, so no audio stream is written rather than a silent one. The Audio Codec list still shows what Ogg expects — Vorbis by default, with Opus, Speex and FLAC alongside it. If you add a soundtrack later, Vorbis or Opus are the codecs an Ogg file should be carrying.

The Constraint Quality option disappeared when I chose Theora. Why?

Because that mode does not apply to the Theora encoder, so the interface removes it rather than offering a control that would be ignored. With Theora selected you have the Quality Preset and Constant Quality; with VP8 selected, Constraint Quality is available as well. This is normal behaviour across the site — the option list reflects what the chosen codec can actually do.

What resolution will the video be?

The photograph's own dimensions unless you set otherwise, with the frame prepared at no more than 4096 pixels on its long edge before encoding — so a high-resolution modern raw is scaled down to fit. For web use you almost certainly want something far smaller: pick a Fixed Resolution such as 1920 x 1080, or set Width x Height in Pixels, rather than publishing a clip made from a full-size sensor frame.

Can I get an ordinary video out of this instead?

Yes, and for most purposes you should. CR2 to MP4 produces a clip that plays on phones, in browsers and on social platforms without anyone thinking about codecs, and OGV to MP4 converts an Ogg file you already have. Reach for OGV when something has asked for it specifically; reach for MP4 when the file simply has to work.
