![]() ![]() Anything requiring power generates heat, and the harder it works, the more power it needs, and the more heat it generates. When you're recording the RAW data, the camera is no longer compressing the image to H.264, which is normally a very processor-intensive task and requires a decent amount of power. What does this mean exactly? The camera sensor is doing no more work than it was already doing in Live View - even if you aren't recording anything. ![]() To put it very simply, Magic Lantern found a way to access that RAW data stream from the sensor before it gets to the LCD or the H.264 compression. This missing information is then interpolated later by surrounding pixels, and that's how we end up with something we can actually look that (which is also the reason it's helpful to start with more resolution than you need on single sensor cameras). RAW sensor data with most single sensor cameras (like DSLRs) is missing a ton of information because each pixel only represents one color (Red, Green, or Blue). This usable video resolution is still in a RAW form, which means if you looked at it as-is, it looks terrible. In Live View mode, the Canon cameras take all of the pixel information and scale it down to a usable video resolution (how exactly they are doing this, only Canon knows, but not all of the cameras are doing it exactly the same way - some might pixel bin, line skip, or a combination).
