While I am shooting footage my camera always stops a 12:21 no matter what SanDisk card I use. I currently bought the Extreme PRO card with 64GB and 95MB hoping it would speed up the card to keep up with the camera but it still stopped at 12:21. Please could you help me figure out how to keep my camera from stop recording while I'm filming?
So, it is possible, but not that easy I thought before. You need to install Magic Lantern, format exFAT and make the card bootable with EOScard. I think it will be easier for you to use a software to put the videos together.
Seems I hadn´t read everything. Only works when video recording in raw format. Nothing to do. Your camera is also too slow to video record in raw format. You will at least need a 5DIII for HD and good quality.
