How do I work out how many minutes of video I can get into 1 GB of SD card space?

Regards

Depends on resolution and/or framerate.
I believe 1080/24p is 12 min (plus/minus a few seconds) for 4Gb.
So about 3 min. per Gb.

Here is a t3i manual (go to page 151): http://gdlp01.c-wss.com/gds/0/0300004720/02/eosrt3i-eos600d-im2-c-en.pdf
Canon 7D - EF 16-35mm f/2.8 L, EF - 20mm f/2.8, EF 50mm f/1.4, EF 100mm f/2.0, Custom Cine 50mm & Custom Cine 35mm

Also depends on the model of camera, if you have all-i or ipb temporal compression...  it also depends on your subject, a detailed rapidly changing subject will use up slightly more memory than one where spatial and temporal savings can be made.

What kind if cam do you have?
EOS 3, 7D, 60D, 20D, M, 300x, Arsat 80mm TS, Samyangs f1.4 35 & 85, m22 f2.0, m18-55, EF 50 f1.8, 100 2.0, 70-200 2.8L, Sigma 18-50 2.8, 70mm f2.8, Tokina 11-16 2.8, 400 5.6 and lots and lots of grip, lights, sound gear.

too many curve balls here mate.

most manufacturers let you download a pdf of the manuals these days.   For a definitive answer try that.
EOS 3, 7D, 60D, 20D, M, 300x, Arsat 80mm TS, Samyangs f1.4 35 & 85, m22 f2.0, m18-55, EF 50 f1.8, 100 2.0, 70-200 2.8L, Sigma 18-50 2.8, 70mm f2.8, Tokina 11-16 2.8, 400 5.6 and lots and lots of grip, lights, sound gear.
