Need help with FCE import (1920x1080)

I'm new to FCE and unfamiliar with the settings and format.  I bought the software in order to use one third party filter on a particular four minute project.  I thought this would be easy (I'm not even editing the show in Final Cut, just applying a filter.)  But  I've spent literally days watching tutorials and reading discussions trying to get settings and file formats right for a simple four minute project.
Here's my situation.  I created a video in Photo to Movie.
I exported it with the following settings:
HDV 1080i
     Dimensions: 1920 x 1080
     Video
          Compression: Apple Intermediate Codec
          Quality:  Medium
          Frame rate: 29.97
          Preset: HDV 1080i
     Sound:
          Format: Integer (Big Endian)
          Sample rate: 48.000 khz
          Sample Size: 16-bit
          Channels: Stereo (L R)
Initially I was working in version 4 and could only work with the 1440 x 1080 sequence settings.  The film looked great in FCE but rendering was giving me poor image quality.  I thought this might be a problem with sequence settings.
I just updated to 4.0.1 so that I could work with 1920 x 1080 dimensions.  In Easy Setup I selected AVCHD  Apple Intermediate Codec 1920x1080i60. 
But when I drag my Quicktime movie into the browser it's listed as 1440 x 1080.  I'm puzzled as I'm sure I formatted it at 1920x1080 and if I
use command+i on the .mov file it shows as 1920x1080.
I'm completely confused.  I have MPEG Streamclip and Iskysoft media converter if that's useful.
Can anyone tell me where I'm going wrong?
In the initial export of my Photo to Movie project?
In my import into FCE?
Both?
I'm far behind my deadline and really need some help.
Thanks, in advance, for any assistance.

Hi Tom, you are right, of course.  The inspector says:
Apple Intermediate Codec, 1440 x 1080 (1888 x 1062)
Millions 16-bit integer (Big Endian)
Stereo (L R)
48.000 kHz
FPS 29.97
Playing FPS (Available while playing.)
Data size: 2.66 GB
Data rate: 89.58 mbits/s
normal size: 1888 x 1062
current size: 1888 x 1062
I won't ask you to explain why I fed in one resolution and ended up with another or why the file shows up in the  preview menu as being 1920x1080.  Obviously I don't understand these basic concepts.
The more immediate question is--which settings should I be using to import into FCE (or should I be converting this to something else before it's imported into FCE?)
Finally, when it's time to export (after applying the filter) which settings should I use?
I need a high quality version that can be put on a DVD and also something that can be used on Youtube. (The more urgent need is for the You Tube file).  
I truly hate to bother you with all this, but it's remarkable how many different online tutorials I've consulted and they all differ.  I've probably spent thirty hours this week trying different approaches (insane).  Each asserts that this or that format and setting is the "best" but no one seems to agree.    And none have entirely worked so far.  (I even had a professional come to my house this morning to help and he told me all my settings looked fine--obviously not true.)  Ultimately I need to understand the underlying concepts (and should have invested my time this way) but in the meantime, I urgently need to get this project out. 
I saw in other posts that you have written about FCE.  Is there a particular title I should pick up to get a good overview of these concepts?  And, in your opinion, does it make sense to study FCE when everything seems to be moving toward the Pro X software?  I ask these additional questions, in part, for the benefit of others.  I'm sure I'm not the only layman out there who is struggling with this learning curve.  Thank goodness for individuals like you.

  • Need Help with FCP7 import and plug in question.

    Hello,
    I just registered and would like to ask two questions. Everything else I'll use the search function for but I need the answer right away.
    Ok First question. I have a mac pro at home and a intel macbook both with FCS4 during the holiday season I'd like to work on a project on my laptop. Now I have all my files on a 2.0 USB drive(I know its not that fast for video) but this is only temp. while traveling. I'm trying to figure out why it wont import the files into another project. Even when I'm at my home Mac Pro when I try to import a projects footage into another project it doesn't read it. This comes up
    "File Error: 0 file(s) recognized, 0 access denied 254 unknown"
    But all the files will work in the project that it was originally captured too.
    If this helps the codec is sonys HDV 1080 60i converted to Apple ProRes 422(HQ) which I found out I should only use the regular Apple ProRes 422. I'm stuck now b/c I cannot import the files into a new project to work in on my laptop. Plus my Macbook doesn't have Firewire800 so I have no way to get the footage from tape to my laptop other then my USB Hard Drive.
    I also have problem importing the files in Motion and Cinema Tools they also are not recognizing the files which is getting me upset since they are FCP7 generated files after I convert them to ProRes.
    Whenever I try to import/use the files in anything other the original project they are grey'ed out.
    I'm also confused on how to import effects plug-ins I've downloaded effects from apple only to have now directions to import them into the program.
    Sorry for the Noob questions I'm a film student learning FCP7 by myself so I have the upper hand come next semester. Thanks in advance.

    Can't tell for sure but it sounds as if the drive is not properly formatted, or you do not have correct read/write permissions for it. There is no way you can use this drive with HQ video. You're going to get into problem if you even try.

  • New to the MAC OS and need help with FCE

    I have a number of videos from parties and events I have organized on DVD discs and I want to make a demo combining all these scenes into one DVD. Is there a simple way to import video and audio from a DVD to use in FCE 4. Ive had the computer for about a week and I'm still trying to figure it out so any help would be nice.

  • Need Help with Order import corrections

    Hi Experts,
    I 'am trying to edit the data entered into the interface tables for a failed order import through the corrections window. I made changes to the error attribute, say - Inventory_item_id for lines and saved the changes. When I click on "Validate", I always get the error: "Error You are trying to insert an existing order or update an order that does not exist. Please enter a correct operation code." I get the same error for "UPDATE" and "CREATE" and blank values for "Operation Code".
    Can you please guide me on how to use the corrections window to import a failed order.
    Thanks,
    Ganapathi

    I 'am not certain whether I 'am using the corrections window incorrectly or this is a bug. Please suggest. I 'am on 12.0.6. The "Import" button remains disabled and the "Validate" button always fails. Any inputs on this will be immensely helpful.
    Thanks,

    Thanks for the help. Bob K ---  [email protected]

      Are you scanning as jpeg, tiff or some other format?
    Are you using continuous numbering for files names as by definition scanned files have no exif data.
     

  • Really need help with MSI R7970-2PMD3GD5/OC:(

    Greetings to all,
    I really need help with my brand new MSI R7970-2PMD3GD5/OC. I've purchased it two days ago and I didn't really have time to test the card until yesterday. The card is I think way to hot for my "liking". It idles at 56c-60c, at full load in Heaven benchmark 3.0 in 1920x1080, extreme tessellation and 8xAA card reaches 95c-97c. Stock cloacks are 1010Mhz/1375Mhz and stock voltage is 1,174v. Case is being cooled by two Noctua NF-P12 fans. Also I tried lowering the voltage and "underclocking" the card to a standard 925Mhz in small increments, but it doesn't help at all. Each and every time it results in BSOD and dx dll errors and complete system failures. Replacing the card wouldn't be a problem if I lived in a "normal" country that has access to a steady supply. Retailer that sold me a card told me that only 5 cards total have been imported from the launch day and told me that i bought the "last" card in my country. They could order a replacement but it would take them more then a month to do so.:( Ohhh and one more thing I don't overclock, everything in my case is at their default values.
    Recently, I read that "Amd released" a bios update for a standard reference boards that turns them into a "GHZ editions". Also lot of users report a lower voltage requirements and lower temps with that "boost bios". As I understand this card pcb is not Amd's reference board design, I could be wrong it's not that uncommon.. So I didn't want to risk warranty by flashing it to a position 1. Will MSI release the boost bios for this model of card? I am humbly asking MSI staff on how to proceed regarding this problem. I would be immensely grateful for any help you could provide.

    what PC case you use exactly?
    have you tried to open PC case side door and to retest?
    Hi,
    it's open case. If i close it the temps get even worse:(
    They get better for other components, but not for gpu. Two Noctua NF-P12's are cooling the case, first one is positioned above gpu, left side next to cpu. Other is right beneath the gpu, right side of case. Just under the hdd section of the case. I tested each and every component with my backup card nv 8500gt. They function within the specified parameters. I'm getting somewhat worried.

  • Need Help With File Matching Records

    I need help with my file matching program.
    Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
    When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
    Here is my following program code:

    I am not sure what is wrong with my code above to make my results different from the correct results.
    Much help is appreciated. Please help.

    From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
    As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
    Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
    Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.

  • Need help with calculator project for an assignment...

    Hi all, I please need help with my calculator project that I have to do for an assignment.
    Here is the project's specifications that I need to do"
    """Create a console calculator applicaion that:
    * Takes one command line argument: your name and surname. When the
    program starts, display the date and time with a welcome message for the
    user.
    * Display all the available options to the user. Your calculator must include
    the arithmetic operations as well as at least five scientific operations of the
    Math class.
    -Your program must also have the ability to round a number and
    truncate it.
    -When you multiply by 2, you should not use the '*' operator to perform the
    operation.
    -Your program must also be able to reverse the sign of a number.
    * Include sufficient error checking in your program to ensure that the user
    only enters valid input. Make use of the String; Character, and other
    wrapper classes to help you.
    * Your program must be able to do conversions between decimal, octal and
    hex numbers.
    * Make use of a menu. You should give the user the option to end the
    program when entering a certain option.
    * When the program exits, display a message for the user, stating the
    current time, and calculate and display how long the user used your
    program.
    * Make use of helper classes where possible.
    * Use the SDK to run your program."""
    When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
    when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
    Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??
    Here is the programs code that I've written so far:

    Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??You cannot restrict the user. It is a sad fact in programming that the worst bug always sits in front of the Computer.
    What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
    AND you might want to ask yourself why the heck a calculator needs to know the users Name.

              catch(IOException a)
                         System.out.println(a.getMessage());
    }the only problem now is about how it should display the right info about the person whenever i click its name on the list.. something about file reading or something, i just cant figure it out.
    and also about how to make it scroll once it exceeds the list.. i cant make it work, maybe something about wrong declaration..
    thanks in advance..

    Like said before, do one thing at a time. At startup, something like:
    //put all the content in a list
    ArrayList<String> lines = new ArrayList<String>();
    while(String line=rand.readLine()!=null) {
        lines.add(line);
    }If you follow the good advice to create a class to encapsulate the entries, you could populate a list of such entries like this:
    static final int ENTRY_SIZE = 3;//you have 3 fields now, better to have a constant if that changes
    ArrayList<Entry> entries = new ArrayList<Entry>();
    for(int i=0; i<lines.size(); i+=ENTRY_SIZE) {
        Entry entry = new Entry(lines.get(i), lines.get(i+1), lines.get(i+2);
        entries.add(newEntry);
    }You could also do both of the above in one run, but I think you will understand better what's happening if you do one thing at a time.
    If you don't want to put the entries in an encapsulating class, you can still access this without looping:
    int listStartIdx = <desired_entry_index>*ENTRY_SIZE;
    String att1 = lines.get(listStartIdx).substring(1);
    String att2 = lines.get(listStartIdx+1).substring(1);
    String att3 = lines.get(listStartIdx+2).substring(1);

  • Need help with installation

    I recently received a laptop from school to access my online classes.  When I tried to use Adobe Reader I received the following message:  Adobe Reader 9.1 has encountered a problem and needs to close.  Sorry for the inconvenience.  I tried tech support at school and was told to uninstall and reinstall the program.  During the installation process I received the following error:  Error 1321 The installer has insufficient privileges to modify the file C:/Program Files/Adobe/Reader 9.0/Reader/Onix32dll. I need this program for school.  Can some one please help me.

    Hello again, Michael,
    Was unable to do the UAC changes.  Buttons where not highlighted.  I just went ahead and uninstalled Adobe and downloaded Foxitsoftware and it works.   Thanks for all your help Michael you have made my online school experience better.
    Sincerely,
    Sherri Lee

    Subject: Need help with installation
    Hello again, Sherri:
    It's my pleasure to provide assistance when I can :•) Having just recently graduated after 7 years of effort just to get a 2-year degree, I can relate to needing software to get class work accomplished. I will do everything I can to make it happen for you today.
    Since you didn't mention, the UAC setting, I'd like you to disable it for me if it isn't already:
    1. Open Control Panel
    2. Under User Account and Family settings, click on the "Add or remove user account"
    3. Click on any user account
    4. Under the user account click on the "Go to the main User Account page" link.
    5. Under "Make changes to your user account", click on the "Change security settings" link
    6. In the "Turn on User Account Control (UAC) to make your computer more secure" click to unselect the "Use User Account Control (UAC) to help protect your computer". Click on the Ok button.
    7. You will be prompted to reboot your computer - do so when ready
    You may need to uninstall/reinstall Reader after the reboot in order for the problem to go away, but that part I am not certain of. Try to duplicate the issue prior to taking that step.
    If you are unable to resolve issues with Adobe Reader, I recommend using a different reader that has much less bloat and is updated regularly:
    http://www.foxitsoftware.com/pdf/reader/
    FoxIT is a FREE alternative to using Adobe's Reader. Support for free Adobe products is limited forums such as this. The same holds true for open source alternatives except the manufacturer usually helps support their forums while Adobe doesn't monitor this forum or any like it. I know how important it is for you to focus on your classes so don't beat your head against a wall just because Reader won't work when a viable solution exists.
    Best of success in your pursuit of knowledge!

  • Need help with connecting file inputs to arrays

    In this assignment I have a program that will do the following: display a list of names inputed by the user in reverse order, display any names that begin with M or m, and display any names with 5 or more letters. This is all done with arrays.
    That was the fun part. The next part requires me to take the names from a Notepad file, them through the arrays and then output them to a second Notepad file.
    Here is the original program: (view in full screen so that the code doesn't get jumbled)
    import java.io.*;       //Imports the Java library
    class progB                    //Defines class
        public static void main (String[] arguments) throws IOException
            BufferedReader keyboard;                                  //<-
            InputStreamReader reader;                                 //  Allows the program to
            reader = new InputStreamReader (System.in);               //  read the the keyboard
            keyboard = new BufferedReader (reader);                  //<-
            String name;                 //Assigns the name variable which will be parsed into...
            int newnames;               //...the integer variable for the amount of names.
            int order = 0;              //The integer variable that will be used to set the array size
            String[] array;             //Dynamic array (empty)
            System.out.println (" How many names do you want to input?");   //This will get the number that will later define the array
            name = keyboard.readLine ();
            newnames = Integer.parseInt (name);                                         // Converts the String into the Integer variable
            array = new String [newnames];                                               //This defines the size of the array
            DataInput Imp = new DataInputStream (System.in);       //Allows data to be input into the array
            String temp;                                       
            int length;                                                                  //Defines the length of the array for a loop later on
                for (order = 0 ; order < newnames ; order++)                                //<-
                {                                                                           //  Takes the inputed names and
                    System.out.println (" Please input name ");                            //  gives them a number according to
                    temp = keyboard.readLine ();                                           //  the order they were inputed in
                    array [order] = temp;                                                  //<-
                for (order = newnames - 1 ; order >= 0 ; order--)                                //<-
                {                                                                                //  Outputs the names in the reverse 
                    System.out.print (" \n ");                                                   //  order that they were inputed
                    System.out.println (" Name " + order + " is " + array [order]);             //<-
                for (order = 0 ; order < newnames ; order++)                                  //<-
                    if (array [order].startsWith ("M") || array [order].startsWith ("m"))     //  Finds and outputs any and all
                    {                                                                         //  names that begin with M or m
                        System.out.print (" \n ");                                            //
                        System.out.println (array [order] + (" starts with M or m"));         //
                    }                                                                         //<-
                for (order = 0 ; order < newnames ; order++)                                            //<-
                    length = array [order].length ();                                                   //
                    if (length >= 5)                                                                    //  Finds and outputs names
                    {                                                                                  //  with 5 or more letters
                        System.out.print (" \n ");                                                      //
                        System.out.println ("Name " + array [order] + " have 5 or more letters ");      //<-
    }The notepad file contains the following names:
    jim
    laruie
    tim
    timothy
    manny
    joseph
    matty
    amanda
    I have tried various methods but the one thing that really gets me is the fact that i can't find a way to connect the names to the arrays. Opening the file with FileInputStream is easy enough but using the names and then outputing them is quite hard. (unless i'm thinking too hard and there really is a simple method)

    By "connect", do you just mean you want to put the names into an array?
    array[0] = "jim"
    array[1] = "laruie"
    and so on?
    That shouldn't be difficult at all, provided you know how to open a file for reading, and how to read a line of text from it. You can just read the line of text, put it in the array position you want, until the file is exhausted. Then open a file for writing, loop through the array, and write a line.
    What part of all that do you need help with?
