No 3X video Crop Mode on the 6D?

[ImJim]

Hey folks,

Recently got my 6D (upgraded from my 700D), immediately installed ML. One thing I've noticed is that there's no 3X movie crop mode function, just as the 600D/700D's ML had. Is it due to the fact it's a full frame sensor? I want my 3x crop back on the 6D Obviously I'm not talking about the RAW 3x crop, which works... I'm taking about the crop we could do with the APS-C cameras, working with H264...

Looking forward to your replies guys,

Happy new year
