Why is audio file size larger than in Flash?

I use both Flash and Captivate. Final file size is a big consideration. I wondered why the file size of the audio in Captivate is almost twice as large as the same audio if it's used in Flash. I'm using the same audio settings for both. Does anyone know what causes the audio compression to be different in Captivate than in Flash?

OK, sounds like memory will be fine, so let's look at some other stuff...
Is it only one particularly keynote presentation that slows up for you, or does keynote behave in the same way even if you start from scratch and create a new presentation?
If it's just the one presentation then there's probably some content (possibly video) within it that KN takes exception to. Sometimes a single problematic slide or piece of content can slow down the whole app.
Is the problematic presentation one that was imported from Powerpoint? If so, import it again and look carefully at the import error/warning logs.
Before you start keynote, start up activity monitor - which will give you an indication of what programs are using all the CPU/memory/disk bandwidth etc. You'll then have an idea of whether it is KN maxing out on CPU or whether anything else is dragging the system down.
Another thing you could try would be to log in to a different user account on your machine (create one if necessary) and then try opening the presentation from within this different account. If this works for you then it suggests a problem with the keynote plist file in your original user account.
I don't know if it'd be acceptable to you, but if you could post a link to your problematic presentation then I could download it and try it out on my normally reliable Keynote on one of my computers. (Make sure that you've ticked the box to embed all media in the presentation)
Hope some of this is helpful,
Mike.

  • Why Are Lightroom File Sizes Smaller Than Elements Equivalents?

    I have been struggling to get good quality thumbnail sized images at small enough file sizes for a website. The only problem is that the versions I have done through Lightroom via the Web Module using the Flash template, will only allow a maximum width size of 191 pixels, whereas I'm looking to achieve 250 pixels wide. Doing it through Elements image resize box gets me the size I want, but for a decent quality, the file size is much larger. 
    Out of curiosity and for comparison, I made the Elements versions the same dimensions as the Lightroom ones. In order for the file sizes of the Elements ones to come even close and yet not as small as the Lightroom versions, I had to reduce the Jpeg quality to zero. This rendered them unusable.
    I can't understand why two related applications doing exactly the same thing can differ so wildly. Can someone tell me what is going on?

    Hmmm??
    Not To Sure??
    But I will try to find out..
    Keep you posted about that.

  • Time machine backup file size larger than size of backup hard drive.  Is something wrong?

    My 3 TB external hard drive (My Book Studio) is my Time Machine drive.  But Finder says that backup.backupdb is 6.9 TB in size, or over twice the drive's capacity.  Should I assume that the drive is corrupt or failing and that I can't rely on Time Machine now?  Or is Finder measuring something other than the actual size of the file...?

    I have this problem as well.  I have two laptops backed up to the same external hard drive, and I would like to move just one of the laptop's backups to a new drive.  The partition for both is 600GB, but the size of one laptop's backup folder is 850GB and for the other it is 3.3TB.
    I would like to know the actual size of each laptop's backup folder.  Getting the size of the volume is not useful because I need to know the sizes of the two individual backup folders within it.

  • Why would an alias file be larger than the original file?

    I have a simple document that is 106kb. When I create an alias to the file, the alias is 133kb. Why would the alias file be larger than the orginal file when the alias file is simply a redirect to the original file?

    Francine has a good explanation here:

  • NT 4.0, LabVIEW 6, Error 4 (END OF FILE) when trying to seek to byte offset 4096 (from start of file) when the file is larger than 2 Gig

    If I try to seek (or read) with the position mode wired and set for START, I get error 4 (END OF FILE) if the file is larger than 2 GB. I'm only trying to move the file pointer 4096 bytes, not trying to seek or read more than 2GB, but I get the error if the file is over 2Gig.
    Instead, I have to do reads, with the position mode unwired, until I get to the place in the file that I want to be.
    Is this expected behavior?

    Hello,
    LabVIEW File I/O functions use an I32 value to store the size of a file. This means that we are limited to ~2GB file sizes when using the File I/O functions in LabVIEW. This explains why you are seeing odd behavior when trying to read to the end of the file, since this is causing the byte count to exceed ~2GB.
    I hope this explanation sheds some light on the situation for you. Hopefully the workaround (repeated reads) is not too much of an inconvenience.
    Good luck with your application, and have a pleasant day.

  • Why the flashback log'size smaller than the archived log ?

    hi, all . why the flashback log'size smaller than the archived log ?

    Lonion wrote:

    Flash logs size depends on parameter DB_FLASHBACK_RETENTION_TARGET , how much you want to keep.
    Archive log files is dumped file of Online redo log files, It can be either size of Online redo log file size or less depending on online redo size when switch occurred.
    Some more information:-
    Flashback log files can be created only under the Flash Recovery Area (that must be configured before enabling the Flashback Database functionality). RVWR creates flashback log files into a directory named “FLASHBACK” under FRA. The size of every generated flashback log file is again under Oracle’s control. According to current Oracle environment – during normal database activity flashback log files have size of 8200192 bytes. It is very close value to the current redo log buffer size. The size of a generated flashback log file can differs during shutdown and startup database activities. Flashback log file sizes can differ during high intensive write activity as well.

  • Why does PDF file size increase each time I "save" tagging tasks?

    Why does PDF file size increase each time I "save" tagging tasks?
    Given:
    1) I'm running Acrobat Pro 11.0.07 (this is most current version)
    2) My file size starts at 750mb and ends up 15mb when finished tagging.
    3) Only certain documents experience this increase, i.e., no visible pattern of document characteristics
    4) PDF's are not full of images...in fact, mostly <H1> <H2> <H3> <P> <Figure> alt text, ect.
    5) Occurs with text PDF's and/or fillable forms (again, does not happen to all documents...only some)
    6) File increase occurs incrementally as tagging tasks are performed; i.e., each new save increases file size a few megabytes.
    7) Occurs whether I "save" or "save as"
    8) Difficult to optimize these files without corruption
    9) I'm running Mac OS 10.9.4 (this is most current version)

    Thank you so much for responding! I've been experimenting with the SAVE AS vs. SAVE for the past few days...and you are correct. It's funny because I've been tagging files for 2 years and never noticed this. Probably b/c I use both methods depending on the tagging tasks...some are more complicated than others and should not be overwritten. In those cases I SAVE AS new file.
    I love this forum...thank you again!

  • Load and Read XML file size more than 4GB

    Hi All
    My environment is Oracle 10.2.0.4 on Solaris and I have processes to work with XML file as below detail by PL/SQL
    1. I read XML file over HTTP port into XMLTYPE column in table.
    2. I read value no.1 from table and extract to insert into another table
    On test db, everything is work but I got below error when I use production XML file
         ORA-31186: Document contains too many nodes
    Current XML size about 100MB but the procedure must support XML file size more than 4GB in the future.
    Belows are some part of my code for your info.
    1. Read XML by line into variable and insert into table
    LOOP
    UTL_HTTP.read_text(http_resp, v_resptext, 32767);
    DBMS_LOB.writeappend (v_clob, LENGTH(v_resptext), v_resptext);
        END LOOP;
        INSERT INTO XMLTAB VALUES (XMLTYPE(v_clob));
    2. Read cell value from XML column and extract to insert into another table
    DECLARE
    CURSOR c_xml IS
    (SELECT  trim(y.cvalue)
    FROM XMLTAB xt,
    XMLTable('/Table/Rows/Cells/Cell' PASSING xt.XMLDoc
    COLUMNS
    cvalue
    VARCHAR(50)
    PATH '/') y;
        BEGIN
    OPEN c_xml;
    FETCH c_xml INTO v_TempValue;
    <Generate insert statement into another table>
    EXIT WHEN c_xml%NOTFOUND;
    CLOSE c_xml;
        END
    And one more problem is performance issue when XML file is big, first step to load XML content to XMLTYPE column slowly.
    Could you please suggest any solution to read large XML file and improve performance?
    Thank you in advance.
    Hiko      

    See Mark Drake's (Product Manager Oracle XMLDB, Oracle US) response in this old post: ORA-31167: 64k size limit for XML node
    The "in a future release" reference, means that this boundary 64K / node issue, was lifted in 11g and onwards...
    So first of all, if not only due to performance improvements, I would strongly suggest to upgrade to a database version which is supported by Oracle, see My Oracle Support... In short Oracle 10.2.x was in extended support up to summer 2013, if I am not mistaken and is currently not supported anymore...
    If you are able to able to upgrade, please use the much, much more performing XMLType Securefile Binary XML storage option, instead of the XMLType (Basicfile) CLOB storage option.

  • SAP ISR -XI - SAP POS. File size more than 11 KB failing in Inbound

    Hi All,
    We are implementing SAP ISR- XI - POS Retail implementation using
    Standard Content Store Connectivity 2.0, GM Store Connectivity 1.0, and
    other contents.
    In our Inbound Scenario File-RFC , we are picking files from FTP server
    for sales and totals data and if the size of this sales data file in
    format *_XI_INPUT.DAT is greater than 11 kb , it is failing at XI
    Mapping level, saying Exception occurred during XSLT
    mapping "GMTLog2IXRetailPOSLog" of the application. We have tried and tested at mapping level no error found as this is processing files below 11 Kb successfully with same mappings, Also this is standard Mapping by SAP in form of XI Content Store connectivity 2.0.
    At XI Side we have processed the file of eg: 40 KB  by splitting the record data and making
    file size less than 11KB and it is being processed successfully, but file of 40 kb fails.
    XI Server: AIX  Server.
    There may be some memory setting missing or some basis problem also. Kindly let me know how to proceed.
    Regards,
    Surbhi Bhagat

    hi,
    this is hard to believe that such small files cannot be processed
    do your XI mappings work for any other flows with something more then 11kb?
    let me know about that and then we will know some more
    as this is realy very small size
    maybe your XI was installed in on PocketPC
    Regards,
    Michal Krawczyk

  • When I narrate my keynote presentation, why is the file size so huge?

    When I narrate my keynote presentation, why is the file size so huge?

    Here are the steps so you can see all the files that make up your Keynote…
    Go to the Finder and find your Keynote file and make sure that it has the .key extension on it. If it doesn't, click it and command i to view info and uncheck the box that says Hide Extension.
    Delete the .key and change to .zip and then click the use .zip in the dialog box that comes up
    Double click the new .zip file and it will change it to a folder
    Open the folder there are the files
    Close the folder and add .key to the end of the name and click Add in the dialog box (this will change it back to a Keynote file)
    You might be able to do this and convert the voice narration to a smaller format.

  • Why is my "Combined PDF" file size smaller than the original files?

    Hello!
    I am trying to combine two individual PDF files into a single PDF. Each file is 32mb, however when I use acrobat to combine them, the newly created "combined" file is only 19mb. I believe I've taken the necessary steps to ensure no degradation is happening (i.e. selecting Large File Size in the options panel), but I am still puzzled as to how two files can be put together as one and be smaller than the two separate files with out any compression. What am I missing?
    Thanks in advance!

    When you combine a file it does a "Save As" operation.  This re-writes all of the PDF object in the single file and is supposed to clean up the file, whereas the single files may have had multiple saves which when you look at the internals of the PDF file simply add on to the end of the file.  In other words you get a more cleanly written and optimized file that is also saved for Fast Web View.

  • Why are file sizes larger on lion 10.7 then on SL.

    All my files are larger on OS 10.7 Lion.

    Hi...
    That's because there are diferent ways of calculating and presenting file size

  • Why Is "Export Small File Size" Large?

    Hi, I work in CS3.  Out of 100 brochures, I have two brochures that will not export to a small file size PDF. The settings for export are all the same.  What else should I be looking for?  The sizes are usually 1 MG.  These particular 2 brochures are 5 - 6 MG.  What can I look for to correct this?
    Thanks

    Small size is very dependent on the contents being exported to PDF. Images are readily compressed. Text and vector data isn't. Thus, if your content is primarily text and vector, it is very unlikely that the content can be compressed signficantly more via change of settings.
    Another factor that can relate to image compression is use of any duotones that use spot colors. Such images cannot be JPEG-compressed, only ZIP-compressed.
