Just thinking about what storage size of iPhone I should get my wife. She does like to use her iPhone 3Gs to take videos of our son. Just wondering how big a 1 minute video is at 1080P on the iPhone 5.
 
I think you might be way off...waaaay off.

Here's an estimate of ~180 MB/min or roughly 10 GB/hr (math not shown, see earlier post on multiplying by 60).

180MB for one minute of video? Did I read that right or is that a typo?

You don't need a 1080p video when your phone's resolution is much lower
 
From my video tests, 1 hour ranges 6-7GB. And there isn't a max file length. You can record up to the full capacity of the iPhone. You use 20% battery for every 30 minutes of recording though. So just a little over 2.5 hours on a full battery of video recording.
 
Good point. Could have it set to 720p instead. ;)

Thanks for all the comments everyone.

There is no native option to change the resolution, but Filmic Pro gives you the option to record at 720p and also gives you frame rate options. So 1080p @ 24 fps will also yield smaller files without losing any quality (much smaller decrease, but decrease none-the-less).

Good to know! Thanks
 
So far I've only taken 2 videos with my iPhone 5, a 6:10 video took up 800mb and a 10 min vid took up 1.08gb. Absolutely ridiculous! And there's no option to use lower quality in stock camera app.
 
I believe your calculation may be slightly out. 2 hours of 1080p video on the iPhone 5 would be around 21GB if you base your calculation off one minute of 1080p video being ~180mb.

For me: 64 seconds = 133 MB / 10 seconds = 22.6 MB

Yes, you bought an HD camera.

No typo. I just did the experiment, though, and made 2 one-minute videos. One was of a static scene, the other was with lots of motion. The static scene clocked in at 152MB, and with motion, 153MB.

Personally, I use ProCamera to shoot at 720p, which is plenty for the lame stuff I tend to shoot.

BTW, ProCamera is awesome for photos, too. I recommend it as a full camera app replacement.

Aren't certain variables such as sound, amount of motion etc that factor into the file size?

Yes absolutely. If you record in a soundproofed room with the camera facing the ground recording darkness you'll find 6 GB will take you a LOT farther than recording say, a sporting event with lots of action (changing colours/pixels being detected by the sensor is one of the main factors) which would probably only give you about an hour I believe we arrived at? If you have a 32/64 GB phone nothing to worry about, you'd run out of battery before you ran out of HD space.

No, that's about right. I used my iphone 4S to record classes that were between 30min and 1hr long and used up anywhere between 4 to 8 gigs of storage.
