When selecting your RAW recording size, look at the bottom of your screen.
ML will tell you the data rate of the *frame rate and pixel dimensions you’ve selected. Anything over 20 MB/s is faster than the 60D can write to the card, and will cause recording to stop when the camera’s buffer is full.
You can maximize the size of buffer available to ML RAW by going into the Canon menu, and setting stills quality to the smallest JPG. Also set Auto Power Off to OFF.
Too, for most stability while shooting RAW, once you have made all the settings you need for your scene, turn off Global Draw.
*Related to this is that you can film larger pixel dimensions at lower frame rates. I sometimes shoot timelapse at maximum possible resolution, at up to 7 frames per second, which still generates less than 20 MB/s to write to card.
It also means that many of us (as you seem to as well) have begun using wider aspect ratios such as 2.39:1, common in feature films… something we might not have explored, without the limitation of 20 MB/s.
We also plan our takes better, so that we can capture what we need in the 30 seconds or so we have available to us in RAW. That’s longer than many scenes we see in finished films: it forces us to be organized!
There’s no just-letting-the-camera-run-for-minutes-on-end, with 60D raw.
Finally, once you’ve finished filming, be sure in the Canon menu to set stills quality and Auto Power Off back to your preferred settings! You wouldn’t be the first ML user to take a bunch of tiny JPGs of something important, or to have your battery die because you were depending on the camera to shut itself off
