Canon 5D mark III Shooting 24fps RAW Video!

By fotosiamo on May 13th 2013

It hasn’t even been one month since we learned that the team at Magic Lantern was able to record 14fps RAW video from the Canon 5D Mark III, but as reported by, lourenco from Magic Lantern has successfully recorded continuous video at 24fps 1928×850 All-Intra, which gives him enough room to crop to 1920×817 for 2.35:1 wide screen aspect ratio.

Canon 5D Mark III RAW video vs h.264 Video

This sample RAW video is recorded at 1920×820 resolution at 3MB/frame or 72MB/second. Note the exposure inside and outside the room, as well as the black shoe.

Here is the standard h.264 video that comes with the 5D mkIII. Note the overblown highlights outside and the clipped black shoe inside.

Pros and Cons of RAW Video

Just like RAW stills, the major advantage of RAW video is the expanded dynamic range and resolution. What’s more, with the progress that Magic Lantern is achieving, it is starting to look like that having RAW video may become a reality for Canon 5D Mark III users (no word on the mark II DSLRs, though).

There are some bad news, however. First, at 72MB/second for 24fps video means you will have some serious space issues to think about. Additionally, lourenco was shooting into a Lexar Professional 1000x 32GB CF Card and it’s pretty much guaranteed that a high-capacity, high-speed CF cards will be required. The RAW video’s super-high data output rate is the reason why the Blackmagic Design Cinema Camera and RED cameras record to SSD.

Finally, stability will be a challenge for extended recording time because there is a higher chance that the sensor can overheat due to the RAW output. It’s one of the reasons that the Panasonic GH3 can be rock-solid in extended 1080p 60p video. That camera actually has a heatsink built into the body to specifically to dissipate heat during filming.

    Just show how companys limit there technology so they can make money with extra products, hopefully this will change with people like Blackmagic so other companys will also have to innovate. Also Canon has said that they don’t have enough engineers to work on software, why not hire some of the people at Magic lantern?

    But on another note magic lantern have done a great job and thees videos are “The Dogs bollox.”

      Because Canon wants to sell their premium cinema camera, like the over-priced 1D C, C300, etc.

      Blackmagic has the luxury of having 3 fairly distinct products that won’t necessarily cannibalize each other, including the 2.5k BMCC since it has better dynamic range than the 4K Production Camera

    But the Blackmagic Design Pocket Camera will not require SSD drive to capture RAW @ 1080p.

      That’s true, but the Pocket Camera is recording compressed RAW. It’ll be interesting if Magic Lantern can pull that off. I think it’s going to be uncompressed RAW from the Canon 5D mkIII, which is going to be a storage nightmare.

    Over blown highlights will be a thing of the past. I love Magic lantern for pushing their technology.
