Canon t3i raw capabilities

[exyide]

Hi sorry if this is a very basic question but I am new to magic lantern and raw video filming. I have a canon t3i and I want to use magic lantern to shoot in raw, I found a chart on the site but I don't understand it at all. My question is with my camera and shoot video in raw what resolution would I be able to film at and for how long?

This is the chart I found

Also what does it mean when it says crop mode?

Thanks.

  Do it like I did:
  Select the desired frame rate and test all resolutions available.
  Crop mode = Zoom mode
