I use 1080p NTSC, 30 fps get about 2 hours out of a 16gb card, and that aligns with battery life too. Of course you're in uk so pal, may be more appropriate, but if you only going to post on the web it won't matter, if your going to play back on a tv, then it matters.
I will say I used 720 and the picture quality on my pc was markedly worse, ok , but worse. So I went back to 1080 , again depends if yor going to cut DVD's for tv playback if so 720 will be fine for most use.
Standard disclaimer - I'm not an expert but these are thoughts ymmv. Have fun
