The vertical resolution is automatically set by the aspect ratio that you choose. ML RAW Video allows you to set the horizontal resolution, in small increments from 640 to 3520. There are two key RAW video options that will affect whether or not your SD card can keep up with the large volume of data that you’re throwing at it. I tested all of my various SD cards in order to determine which one would allow for the highest resolution recording without dropping frames. Press SET to turn RAW video on, and then Q to configure the settings. Once you’ve installed ML on your 600D body, you can learn how to install the nightly build with RAW video here: When you have the ML nightly with RAW build installed, you’ll notice there is now a new menu option for RAW Video: What this means is that the lower speed SD cards are only able to sustain recording for any length of time by shooting at a reduced resolution (we’ll talk more about that later). Canon bodies which use CF cards are able to record at 80-90MB/second, whereas the majority of SD cards are limited to 15-25MB/second. The limitation on Canon’s more consumer oriented DSLR bodies lies in the bottleneck at which SD cards are capable of writing. There are known severe limitations for Canon DSLR bodies which use SD cards, versus bodies such as the 5D Mark III, which are recording full 1080p HD RAW video to CF cards without any problems. ![]() With the recent addition of RAW video recording to Magic Lantern, many owners of Canon DSLRs have been anxious to see how their various camera bodies will perform. The Canon H.264 video was shot using the Giles 35 profile, and has not been corrected or adjusted in any way.

I developed the DNG files in Adobe Camera RAW to match a “flat profile” such as Giles 35 or Flaat. Previously, these settings and exact gear had worked flawlessly without any dropped frames, purple frames or unusual behavior.īelow is the graded and ungraded versions of the test shots. Interestingly, I also encountered some purple frames and other anomalies while recording these RAW clips. ![]() I tried as close as possible to match the framing and shots for both recordings. I’ve updated the test videos to include a side by side comparison between the Magic Lantern RAW Video and the standard T3i H.264 video. UPDATE 7/10/13: Side by side comparison video now available It’s simply the perspective of a video enthusiast who’s curious to see what you can realistically do with RAW on a prosumer DSLR body, right now. Nothing that’s being done here is revolutionary, ground breaking, or even necessarily the correct or best workflow. It’s written from the perspective of someone who has no previous familiarity with a RAW video workflow. DISCLAIMER: This is intended to explore what’s realistically possible right now with shooting RAW on a Canon T3i.
