Does anyone know the bitrate of iPhone 4's HD video?

I'm deciding whether I should buy the 32GB or 16GB gig model, and info on the bitrate of the HD video it records would be useful.
For instance, on the tech specs page it says it supports playback of up to 35mbits/second, but it doesn't say what it records at.
For instance, if it does record at 35mbits/second, that's 15GB/hour. So that means the 16 gig model will basically be able to record and store no more than an hour of HD video.
But you don't need 35mbits/second for HD to look good. You can actually get away with 4mbit/second, which effectively allows for 8 hours of recorded HD video storage on the 16gig model.
Anyone know what the HD recording specs are? Apple doesn't seem to list them anywhere.

Hmmm, well maybe I can answer my own question. I found this raw video from the 3Gs
http://stadium.weblogsinc.com/engadget/videos/penny_chase.MOV
Looking at the stats, it's 640x480 @ 4mbit/s and the compression quality looks fantastic. I'm going to assume that Apple will try and aim for the same compression quality for the 1280x720 resolution of the iPhone 4 video recording.
Since 1280x720 has 3x the pixel area as 640x480, it will require roughly 3x the bit rate to look just as good. It's not that simple, but it should be a good approximation.
So I'm guessing the bitrate will be around 12mbit/second in order to maintain that same compression quality @ 30FPS. That will translate to roughly 5GB/hour of video.

    Does anyone know if my G3S Iphone will sync Itunes on my MAC Power PC G4, OSI0.4.11?  If it will, what operting system does the Iphone need?

    My apologies, I read your post the wrong way. I see now that the original poster was confused about the specs and you were simply responding with the appropriate info.
    I've gotten defensive after reading the forums. The forums are full of posters just looking to prove someone wrong or stupid, rather than being helpful. I shouldn't have assumed you were one of those people. Sorry.
    I did my homework and discovered that my PowerPC will run Leopard. It can be purchased for $129 by calling 1-800-MY-APPLE. This is much cheaper than replacing my laptop.
    I hope to upgrade my Mac soon, though! Can't believe this thing is still ticking. I love Apple.

    It may seem simple, but restart both devices.
    on the iPhone hold the sleep and home button until the phone rests (soft reset), then restart the iTunes app. Then plug the phone back in then sync again.

  • Does anyone know the iso range on the video camera / still camera?

    I'm shopping around for camera's right now, my budget is very limited, and though I suspect almost any camera will have better low-light detection than the iphone 4 (not 4S), I don't know that for sure, because I can't find the iso range in the tech specs, and as we all know, Apple hardware can be surprisingly good. So, does anyone know the iso range for the iphone 4 (not 4S) ?

    Set the pixel aspect ratio in Live Type: Edit > Project Properties. It needs to be at 1:42.
    When you bring the file into FCP, right click it in the browser, choose Format and click next to Anamorphic to place a check mark next to it:

  • Outgoing Email Setup for Knology - Does anyone know the server setting?

    A friend cannot find the Knology server settings for outgoing mail...Knology company was no help.
    Does anyone know the proper settings?
    Thanks

    DBunch07,
    I was able to find this site in their support pages:
    http://support.knology.net/content/email.setup.cfm
    If the suggested setting from there smtp.knology.net, does not work, they may require different settings for when you aren't connected directly to them. For example when using EDGE or a WiFi Hotspot.
    I have found that asking email provider's tech support for what mail server settings to use while you are travelling and using a laptop will often get the correct settings to use for the iPhone. However, if they say they only offer webmail for when you are travelling, you will not be able to use their outgoing server on EDGE or at WiFi Hotspots, because they have chosen to block outgoing access when you are not on their network.
    While connected to EDGE, you can use cwmx.com to send email out. It only works while on EDGE, and does not require a username or password, since it goes off of the authentication for using EDGE with AT&T.
    AT&T's knowledge base article about cwmx.com is here:
    http://www.wireless.att.com/support/knowledgeBase.do?content=KB72769.html
    You will have to turn off WiFi when you want to send email though.

    It should be on the back of the device, and if that doesn't help, then go to www.apple.com and look up specs for the iPhone 5c. That should provide it there.

    Here's the steps to follow if your printer isn't turning on.   
    If you've gone through all those steps and you still don't have power, there are a lot of places that sell a replacement cord and supply for that printer.

  • Does anyone know the default size for 24 in. imac display?

    I inadverently changed the display size on my 24 inch imac. The font in the toolbar at the top of the desktop is larger than I want. Also, when I open windows in different applications, they open larger than the display and have to be downsized in order to see the entire window.
    Does anyone know the default size for this display? Or is there a different way to fix my issues?
    thanks in advance.

    Hi Napamike2: The default setting for the 24" is 1920X1200. If that doesn't get you back to the proper display, maybe you have accidentally activated "Zoom". To check go to System Preferences, Universal Access. Check that Zoom is turned off.

  • I am moving from Southern California to Maui, Hawaii and I need to figure out the best way to get my 24 inch iMac across the ocean. Does anyone know the best way to do this?

    I am moving from Southern California to Maui, Hawaii and I need to figure out the best way to get my 24 inch iMac across the ocean. Does anyone know the best way to do this? I have found GearGrip's LCD harness so that I can do carry-on onto the plane...  Or maybe use a Pelican Case to do it as a "checked bag"? Or any other suggestions??! Please help!
    Thanks so much!!

    I don't recommend you send the iMac in a checked bag. Might get damaged.
    Check the airlines website for carry on guidelines.
    Or, if you have the original box that the iMac came in, if you have someone who can pick up the iMac for you, send it ahead Fed Ex and insure the package.
    Just make sure the display is covered to protect it. A blanket perhaps.

    This is the top story at this writing at AppleInsider:
    Like the updated mid-2014 13-inch MacBook Pro with Retina display, Apple's latest 15-inch notebook brings slightly speedier Intel processors. But with memory, graphics and design all carried over from last year, the most substantial change is a $100 price cut.

  • Does anyone know the file name of the root ($)?

    RoboSource Control unfortunately is not working correctly and a Rollback caused many topics to be permanently deleted. I'm waiting for approval from IT to get the 8.0.1 and 8.0.2 patches applied, but in the mean time we would like to restore our project from server tape backup. Only, I can't find out where the $ root is stored on the server to have it restored.
    Does anyone know the name of the file that is the root? I was expecting to see a file called root or $, but can not locate a file named either.

    Your DB Administrator should be able to recover a TSM backup OF YOUR ENTIRE DATABASE, not the project, from tape.  The database object the DBA is retrieving will not have the $ (or the * sign).  It will be named whatever you named the database when you created the database.
    Your database name is located on the Connection screen.
    Hope it helps...
