  • How Big Are iPhone 4 Photos and Video?


    In trying to decide whether to go all-out for the 32GB iPhone 4 or save a hundred bucks and just get the 16GB, one of the considerations is photo and video size. My whole music library won't fit on any iPhone (or any iPod for that matter), so that's not going to be the deciding factor. But will I regret it if I have a small iPhone and decide to take some video? We don't yet know exactly how big the iPhone's 720p HD video will get, but fortunately, someone has done the calculations and the answer seems to be that you'll want all the space you can get if you're planning on shooting video. Feel free to skip the next few paragraphs if you want to avoid the math.

    Justin Horn at WhenWillApple? did a similar estimate last year when trying to decide whether to get a 16GB or 32GB iPhone 3GS. To determine file size for still images, he just does a simple scale up from the size of the files generated by the 3GS's camera: since the 3GS generates an average file size of 1.3 MB at 3.2 megapixels, Justin figures that the pictures taken on the 5-megapixel camera of the iPhone 4 will be about 2.7 MB each. Not that big a deal… even with a bunch of music and apps on your iPhone, you can probably take a couple hundred pictures before noticing it.

    In order to figure out video size, Justin goes to Apple's best frenemy Adobe. They have a guide up on their website that gives simple formulas for calculating the amount of space that video will take up. First, you determine the size of a single frame using the formula:
    Frame size K = ([Pixel Width x Pixel Height x Bit Depth] / 8) / 1024
    Figuring that the 720p HD camera will image at a bit depth of 24 colors, Justin calculated ( [960 x 720 x 24] / 8 ) / 1024 for 2025 KB per frame. Then, he multiplied that by 30 for the number of frames per second and got the figure of 60.75 MB for each second of uncompressed video. Justin had estimated a 60:1 compression ratio for the H.264 video on last year's 3GS but found that to be a bit high in practice. Assuming a 40:1 compression ratio made the math come out right, so he's making the same assumption for the iPhone 4's video compression, he ended up with 1.518 MB per second of compressed video. So if you want to store as much as 250 minutes of video on your iPhone 4, say 50 five-minute clips, he calculates it will take 21.73 GB (1518.75 KB/sec compressed * 250 min * 60 s / min * 1 MB / 1024 KB * 1GB / 1024 MB)

    Bottom line: unless you want to take four hours of HD video on one go on your phone, or carry that much around in your pocket, you'll probably be fine with the 16GB model. However, if you're taking a bunch of videos, and carry a lot of music, sideload a bunch of apps and have a whole library of books, 32GB might be a reasonable decision. At least, that's what I just talked myself into...

      Yes, folks, time for a paradigm shift: think connectivity, not storage. It's a networked device- store in the cloud. You don't lose stuff that way when a device crashes, breaks, is lost or stolen.

      64gb would need 2 chips if I'm not mistaking....and because the ipad isn't a phone,it's capable of the dual....hope that answers alot of the "why not/when 64gb phone",not enough space.

      I don't think they will ever do this. I don't disagree with you though. It would be nice.

      Perhaps, but with ATT cracking the whip on data usage this can be problematic.

      The difference in resale value is always about $100 difference; has been so pretty much every year. I wouldn't say that adding 16 gigs makes it the "high end". It is the same phones, just with less storage. Another way to look at it is $100 for 16 additional gigs of space. That's over $5 a gig! Pretty expensive if you look at it that way. I imagine the difference in production costs is only a couple of bucks too.

      Yeah I really thought it was going to be 32 and 64. Ughh. I wish I had an extra 100 dollars

      I agree. Navigon on the iPhone is superior to anything I have ever used, including stand alone GPS units. We got rid of our Garmin recently because Navigon is just that good.

      Does the Iphone 3gs have a built-in gps device or it use the internet to track where you go? Doesn't i4 ( iphone 4 ) have a built-in GPS device so it won't need a internet to track where you are going?

      YEAH, why doesn't Apple release 64gb versions, or SS versions, or expansion-friendly versions!? Because as much as some of you think saturating releases with a billion options is the way to go, Apple obviously doesn't agree with that philosophy...and I don't either. I'd rather have this than have "iPhone Home Edition, "iPhone Business Edition", "iPhone Enterprise Edition", etc.

      If you wanna walk around and record your life on the video camera, sync them to your computer, it has a giant SSHD because that's what it's made for, and the iPhone doesn't because that's not what it was made for. Obviously we'd all like 10mp cameras on the front and back, 1080 recording capability, wifi transfer speeds everywhere, and a massive HD to store it all on, but lets get serious for a second.

      I feel like some of you would blindly ***** about anything that got released...some of you would be the ones going "well this is cool, but why didn't they make a hot pink version that goes 100mph and doesn't need fuel" when Ford made the Model T.

      If it's done the Apple way, they'll release a 64 gig version in Nov/Dec, when everyone that bought the 16gb/32gb version are NOT eligible for an upgrade. That's what they did with the first gen iPhone, quietly released a 16gb version at the end of the same year, when all the early adopters had 4gb/8gb models...

      Well me I always get the most gig no matter what the price is ready for my 32gig white iPhone 4.. This is all the iPhone I got (8gig siver black/16gig 3g black/32gig 3gs white....

      Help Please!!!

If you don't plan on shooting videos, I wouldn't bother bumping it to 32 gigs.



      You've got a point there, but also bear in mind that the iphone 4 comes with a faster processor, higher resolution screen, better camera, a gyroscope, accelerometer...all these features will definitely be exploited by devs in the way of apps, and their potentials tested...

      16GB should be adequate if you're not a heavy duty user, but when push comes to shove, and depending on how much you use the iphone 4 and for what, I'd say more room is definitely better

      Thanks for the GPS advice guys, I guess it's the 16 gig for me then. Navigon is 50% off in the Appstore right now, for anyone else considering getting it.

      Well, I know as a fact, that they use two 32gb chips on the touch. and the iphone has only space for one chip, BUT toshiba made a 64gb chip this year some time in february. So they were able to make a 64GB version. It would've been more expensive though.

      If you are in the USA Navigon does seem to be the GPS app of choice.

      I believe they have made a limited number of 64Gb chips - but don't (yet) have the capacity to mass produce them in the numbers required.
