How much space does 1080p video take up?

Correct me if i'm wrong; but i don't think photo stream does video. And if it did, imagine the bandwidth that you would be using if it was on 3G

Also, it doesn't upload it, it just stores a secondary copy, the original video would still be stored on your device and if you were to remove it it would be removed from the cloud too.

And since the carriers are now monitoring usage, you'd hit your monthly allotment faster as well.

Resolution isn't as important as bitrate, so nobody really knows right now.

Sure we do.

The video clip of 1080p hot air balloon footage that's been floating around is 35 seconds and 38 MB. That's 8.6Mbps. So you could cram a maximum of 4 hours of video into a 16GB iPhone 4S.

Does anyone know how much space 1second of iPhone 4 720p takes up approx? We can work it out roughly from that.
