How Much Memory Does RECORD VIDEO Require?

I want to record a video iChat that could go for ninety minutes. How much memory would that take?
Thank you,

Welcome to Discussions, Sandolini
In addition to the info that Ralph has already provided, I offer one additional thought.
Ralph is my guru on iChat, so I am sure he can correct me if I am mistaken, but I believe that iChat 4 (the one in your posted Mac OS X 10.5.8 system info) adjusts camera frame rates and possibly video window size based on connection and processor speeds. I also seem to recall that the maximum video size for iChat 4 is 320x240.
iChat 4's video size/quality decisions are made based on the info from both ends of the video connection. If I am correct, different users could, therefore, experience different video data capture rates, possibly even when connecting to different chat contacts. These capture rates translate directly into different file sizes for recorded videos. In any case, most iChat 4 recordings (maximum size of 320x240) are likely to be considerably smaller (at least one-fourth to one-third smaller) than the 640x480 video iMovie captures from external iSight.
My suggestion is that you record a one minute test, if possible with the same video chat connection. If recording success will be a critical, one-opportunity-only event, you may wish to make several one minute tests to see if there is enough variability that you must account for it. Once you know the file size for a one minute recording, you can calculate ninety times that to find the maximum estimated space required for your ninety minute recording.
When determining your needed space, be sure you leave the extra space Ralph recommends.

  • How much memory does Tiger and Leopold use?

    Hi
    How much memory do both Tiger and Leopold require themselves to run?

    Not much. I've run Tiger and Leopard with only 512 MB (1 GB machine with
    512 MB for OS-X and 512 MB allocated to a virtual machine running Win XP).
    They get really slow with a lot of page-outs if you open more than one app,
    but they do run. The standard 1 GB (with no VMs) is comfortable for web
    browsing and even iPhoto -- as long as you don't open too many apps at
    the same time.
    ...don't know 'bout Leopold, I think he's still dead,

    No one can tell you specifically, as it will vary by device and user and according to your personal data on the device etc. But, you can expect anywhere roughly around 175-195MB.

  • How much memory does SQL Server 2008R2 Standard use on Windows Server 2008 R2 64-bit?

    Hi,
    can anyone tell me how much RAM will really be used by SQL Server?
    72 GB are currently installed. As Windows is only able to use 32 GB is SQL Server able to use the other 40GB + the unused part of the first 32 GB?
    Thank you very much!
    BR Matthias

    Sorry, I don´t understand your post ?!
    Maybe the question is if SQL Server is able to allocate more memory than the installed Windows Version is able to?
    Since your OS is Windows Standard edition(X64) it cannot use or a process running cannot use more than 32 G of memory.
    Now SQL server can use as much memory possible but it is now limited by Windows as your OS can only see 32 G.So it would be good part from your side to go to sp_configure and set 25 G for SQL server and can leave rest for OS( it just a figure not a actual
    value i have given,actual you have to calculate by yourself or refer to below link) .
    http://mssqlwiki.com/2013/04/22/max-server-memory-do-i-need-to-configure/
    As Andrew said after 32 G what ever memory you put it is waste.
    Hope this helps

  • XI Playground - how much memory

    Hello all,
    beside i read all the sizing stuff,
    my question is: How much memory does a Testcomputer need to have a nice System to Develop some Scenarios.
    My first xi had 1,5 GB and that was a bit too less:-).
    Actually a 640 Abap+J2ee Add in in my opinion for testing purposes should run nice with 2 Gbs...

    Hi Felix,
    2 GB should be enough for the beginning, but keep also in mind that the J2EE needs at least 1024 MB for running properly. Recommended Java Heap Size for XI is 1280 MB.

  • Lightroom and CS3 Simultaneously - How much memory?

    I've been trying to use Lightroom's image management features, but need to finish the "keepers" in CS3. The problem is my computer only has 2G of RAM, and both Lightroom and CS3 are giant memory hogs. Has anyone been able to successfully run both programs at the same time (with reasonably complicated PS files consisting of a dozen layers or so) ?
    If so, how much memory does it take? 4G 8G?
    Thanks,
    --Michael

    The wording of your question seems to suggest that your setup has issues with running Lr and Ps simultaneously. Disk thrashing? Memory swapping? Slow performance? What is your machine configuration?
    I have an Intel Dual 2 Core machine with 2Gb RAM and routinely run Lr (on Canon 20D raw files), Ps CS3 beta, Bridge, email client, and Firefox web client all at the same time with little issue.
    And have you consulted Adobe's knowledge base for performance tips?

  • When it says your capacity is 6.43 GB does that mean how much memory you have used up or how much you have left

    when it says your capacity is 6.43 GB does that mean how much memory you have used up or how much you have left

    The 6.43 GB is how much storage that is available to you to use. The difference between 6.43 ansd 8 GB is taken up by the iOS.
    The Available entry show how much is unused.

    I have IMac OSX 10.9.4, 4GB,Processor 3.06 with Intell2Duo. I would like to check for Malware. I run a TechTool Pro 6 every month and that comes up great.
    When check how much memory I am using, with only Safari open I am using 3.9 and more of her 4.0 memory. She is very. very slow in processing. I had 4000
    trash to clean out and it took her over an hour to expel. Also for some reason Safari will not allow me to click on a link, in my G-mail, and let it go to the page.
    It has a sign saying a pop-up blocker is on and will not let me do it. I must open the stamp to look at my e-mails and if I have redirected link now I can do it.
    I have not changed my preferences so where is this pop-up blocker?
    I have looked at preferences on Safari and Google, which I do not understand Google, and do not see where this blocker could be.
    Malware is something I want to make sure is not on my computer. Tech Tool Pro 6 is all I know of and it does not detect Malware.
    Help.

  • How much memory can i put in my imac

    how much memory can i put in my new imac       

    Assuming it's a 27" 2012 machine, it will accomodate up to 32GB. I'd strongly recommend reputable vendors such as OWC (www.macsales.com) or Crucial.
    If you bought a 21.5" iMac the RAM is not upgradeable. The 21.5" machines will accomodate up to 16GB from Apple however you have to order the machine with 16GB directly. OWC does provide RAM upgrade kits for the 2012 210.5" iMacs however it is MAJOR surgergy and is full of risks including fatally damaging the machine and invalidating the warranty.

  • I want to find out how much memory is left on my macbook pro. I need to know steps to find this out.

    I had a problem today as my computer would not save a file for me.  A box stated macintosh HD was full and I would need to clear some files to make room.  I realized that although I had deleted emails from mac mail, gmail had not deleted these and all still remained on my macbook pro.  I went to gmail and finally deleted all the emails, and there were thousands.  I have been able to save a file as of now but want to know how much memory exists on my macbook pro.  It is confusing when I go to the Apple icon in the upper left corner of my laptop as that states my computer has 4gb of memory, two in each slot.  It does not tell me how much as been used.  Any help with this issue is greatly appreciated.  M.

    The bottom of a Finder window will show you how much HD space you have left.
