Track several object at the same time

Hi everybody,
I`m actually trying to tracking several same objects at the same time.
I knew how to do with only one object, and I was able to send the coordinate for each frame in excel. So great.
But now I`m trying to modifiy the code to follow eight objects at the same time.....
My code was already HUGE with one or two objects, but I need to add again 6 part of the same code....
I would like to compact and contract my code to be more clear.....
I suppose there is one solution juste after Labview vision assistant. And i`m sure that there is a way to put all the code to delete the zeros in only one for loop but I didn`nt find the right way....
Anyway if there are some propositions or some ideas, advices..... it`s welcoming
Thks a lot
Sincerely
Maxime 
ps: I put my codewith only two patterns

Yeah -- you have 4 separate tracks with the same audio? Select all 4 tracks/clips in your Event and select Synchronize Clips. You end up with a compound clip in the event with all 4 clips synchronized to the audio. Open the compound clip in a Timeline and select all 4 clips. Use  Video > Transform and type in ~48% (if you want the "gutters") to resize all the clips at once. With the transform icon (lower left corner of the canvas) selected, drag each of your clips out to the four corners (or type in exact position values in Video > Transform > Position parameters.) To get the white background, you can use Generators > Elements > Shapes - set the color to whatever you like; select Rectangle from the drop down and Video > Transform > Scale to expand it to full screen. Drag the generator underneath your storyline to use as a background.
If you don't have audio to synch to, you can create multiple storylines. Add the first clip; reset the playhead and select your other clips that will appear in a 4-up and type Q to *connect* them to the storyline. Then select each one separately and right click > Create Storyline (or type command - G). You can then open each storyline in its own timeline (right click and select Open in Timeline) and append more clips to each "track". Back in the main storyline, drag out each connected storyline to reveal any appended material. The trim control will turn red when you reach the end of media in the created storylines. Resize and arrange as described above.

  • Changing names on several objects at the same time

    Hi, I just got a question from a friend who recently bought a mac. Now he thinks it ***** because he can't change the names of some pictures at the same time. What he want's to do is to mark some objects and then change the names at the same time, he says you can do that on a PC. I have never done anything like it, is it possible?
    Cheers ,Mike

    Hi,
    I haven't used the application myself but read a lot about it.
    The standard Apple application "Automator" can do the job for you.
    You better give it a try.
    The principle is easy: drag the files to the workarea and select the "rename files" script.

  • Downloading several folios at the same time ?

    Hello,

  • Display several bookmarks at the same time in Maps?

    Hi.
    Does anyone know if it's possible to display several bookmarks at the same time in the app Maps on an iPad (mini) under IOS 6.1.3?
    Thanks.

    Do you have to copy each track separately? It would be much easier if I could select all the tracks together for copying/pasting.
    You cannot select multiple tracks in LP9, but you CAN select multiple regions. Use Shift-Click to select the parts on the tracks you want to copy, then hold the "option" key and drag them to the new position. This will create a copy at the new position.
    Let's say you have tracks for piano, drums and bass. In the arrange window, click on the 8-bar "A" part for piano. Hold shift key and click on the drums region then again for the bass region. All three will be selected. Now hold the option key and drag all three sections to the right to place them on bar 25.
    Also, how do you specify that you only want to loop X times? I can get a perpetual loop but I have to turn it off to get it to stop.  This is very inconvenient when I'm playing.
    You can control looping in a few ways.
    1. Go to a region that does NOT have looping checked. Click near the TOP RIGHT of the region in the arrange window. Drag to the right to specify where the looping will stop. This is tricky... if you click too low, it will extend the length of the region. You must click the correct spot near the top to control looping.
    2. For a region where looping is checked, go to the end of the region in the arrange window (at the end of the song) and do as #1 above. Drag to the left until you reach the point where you want the region to stop looping.
    3. Use the "pencil" tool to create a blank region where you want the first region to stop looping. If your 8-bar verse is repeating once, create a blank region at bar 17. The first region will stop looping there.
    Hope this helps.

  • How can I export several versions at the same time?

    Greetings -
    I'm looking for something that I may just be missing, and hoping someone here can point me in the right direction.
    Basically, I'd like to be able to select an image in my library and export several versions at the same time. For example, I select a photo and export JPG, TIFF and PSD versions in one shot without having to run three separate export requests - essentially a batch action. I can't imagine that this isn't built in already - I'm just assuming that I'm missing something obvious.
    Thanks in advance for any advice anyone might have.
    John.

    Fwiw, I've not seen this requested before.
    This kind of Export option is very typical, Kirby, when the rendering of the exported version will take a long time, for example for video or audio. Then you can share several formats at once, to render a version suitable for the web, for viewing on the computer, or the iPhone at the same time. That is really useful, if you render a movie at a full HD resolution and don't have to do it again for an iPhone/iPod version.
    QuickTime 7 does this for the "File > Export for Web" option, for example. You can get three versions of your final movie at the same time.
    And I just checked, the new iMovie Theater does this as well, when sharing a movie to the Theater:
    When you add a movie, trailer, or clip to the Theater, iMovie creates versions of your movie tailored for local playback, playback on an iOS device, and streaming.
    Come to think about it - exporting a webpage from Aperture will also export thumbnail sized images plus a larger version for downloading.

  • How to rotate and translate an object at the same time??

    Hi, I have a problem with rotation and translation of an object at the same time. I wrote a behovior class for my object (a cylinder). When some conditions are true the cylinder is added to a robot arm. Then it is translated so that the cylinder would be very close to the arm (looks like the robot is holding it). And now the behavior should also rotate the cylinder because the angle is 0 and it should be 90. I can translate the object or I can rotate the object but when I'm trying to do it at the same time (I want to combine rotation and translation) it doesn't work.
    Could anyone help me, please :)

    You can used to Matrix3f
    This object is a rotation and translate matrix
    for example:
    private void componerTransformada(){
    Quat4f rot = new Quat4f((float) this.getRotacionSobreX(),(float) this.getRotacionSobreY(),
    (float) this.getRotacionSobreZ(),1.0f);
    Vector3f tras = new Vector3f(-4.0f,-4.0f,(-1)*this.getDistanciaDeLaCamara());
    this.setTransformacion(new Transform3D(new Matrix4f(rot, tras, 1.0f)));
    Quat4f is a matrix of ratation
    vector3f is a direction vector
    Transform3d is building with Quat4f and Vector3f.
    That is work i use this to situe the view of point.
    good locky

    Hi
    In 2010 there was an option for that:
    In the document library of a project site, I want to load several documents at the same time.
    How can we do that in PWA 2013 ?
    Thanks

    Robert,
    Here is a video taht might help. if the Dragging does not work, you could also use the regular Explorer method.

  • Prevent creation of additional common objects at the  same time ...

    Context: A Super User group may require to be allowed to create and/or change queries in Production
    Would be possible to prevent creation of additional common objects like rectricted and calculated key figures and variables at the same time allowing creation of queries in terms of dragging and dropping filters, free characteristics, rows and columns?
    I know that keeping the system closed to changes and using the transport connection Object Changeability it is possible to restrict change of query elements to those that are original in the system.
    Points will awarded.
    Thanks
    Mathew.

    In transport connection Object Changeability, you can only set query elements as modificables but you cant distint between diferent query elements (queries, calculated/restricted key figures, structures, etc).
    You can do that distiction in authorization object in rs_comp and rs_comp1.
    You should combine transport connection Object Changeability and authorization objects in roles

  • Can takes from more than one track be comped at the same time?

    Greetings,
    I know that this question has been asked recently in this forum (http://discussions.apple.com/thread.jspa?messageID=9527542&#9527542), but I don't think that the respondents completely understood the question... Or perhaps I did not understand the suggested solutions to the problem. I will ask the question in a slightly different way...
    Suppose that I record guitar with 2 microphones (a pickup mic, and a room mic). The first microphone is recorded onto track 1, the second microphone is recorded onto track 2. Multiple takes are done in this manner. When it comes time to comp the tracks, how is it done? Can the takes from more than one track be comped together at the same time? I have tried to do this by grouping both tracks together, but it does not work.
    Any suggestions?
    Thank you.

    You had the right idea grouping the tracks together. You must make sure that in the group settings, the box titled "region selection (edit)" is checked. This will allow you to make the same cuts (or in this case, swipes) on all regions in the group.

  • Pattern, Matcher Java classes - Several patterns at the same time

    Hi,
    Thank you for reading my post.
    My post is about the Java classes "Pattern" and "Matcher".
    Pattern class: http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
    Matcher class: http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Matcher.htmlSuppose I want to match two or more different patterns in a character sequence.
    Do I have to scan the whole character sequence (which can be large) twice (or
    more according to the number of patterns being searched)?
    Or: is it possible to scan it only once searching for two or more different patterns
    at the same time?
    I have tried the following:
    private static final String REGEX = "\\bdog\\b | \\bcat\\b";
    private static final String INPUT = "The black cat is teasing the white dog. The cat is nibbling at the dog.";
        public static void main(String[] args)
           Pattern p = Pattern.compile(REGEX);
           Matcher m = p.matcher(INPUT); // get a matcher object
           int count = 0;
           while(m.find())
               count++;
               System.out.println("Match number " + count);
               System.out.println("start(): " + m.start());
               System.out.println("end(): " + m.end());
        }But only "\bcat\b" occurrences are matched...
    Here is the result:
    Match number 1
    start(): 9
    end(): 13
    Match number 2
    start(): 43
    end(): 47Moreover, if "\bdog\b" occurrences were correctly matched too
    how would I make the difference between a "\bcat\b"
    and a "\bdog\b" match?
    Additional question:
    When "cat" is matched, it is not "cat" which is matched but " cat "
    (with a leading and a trailing space).
    Maybe this is obvious but I do not understand why.
    Can you help :) ?
    Best regards,
    Lmhelp
    Nota:
    \b: matches a word boundary.
    "\\bdog\\b" is a regular expression which is used for matching occurrences of the whole word "dog".

    Well, you are right again :) !
    I thank you for the code you sent me
    which allows for instance given the following string:
    "The quick \n${colour} \n${animal} jumps ${how} \nthe ${x} lazy dog.";to return:
    "The quick \nbrown \nfox jumps over \nthe ${x} lazy dog.";
    (I don't know what to replace ${x} with...)In the post I sent previously (#7), I realized I could maybe use the
    "Matcher" class's "group()" method to extract some sub-patterns
    inside the firstly extracted patterns themselves.
    However, I also realized I did not really understand the synopsis of the
    "group(int group)" method:
    String - group(int group) - Returns the input subsequence captured by
    the given group during the previous match operation.and actually when I tried the following:
    private static final String REGEX_TITLE = "<title>(.*?)</title>";
    private static final String REGEX_INNER_LINK = " \\[\\[(.*?)\\]\\]";
    private static final String REGEX = REGEX_TITLE + "|" + REGEX_INNER_LINK;
    private static final String INPUT = "<title>Dogs story</title> the [[little]] dog was eaten [[by]] the big dog.";
        public static void main(String[] args)
        Pattern p = Pattern.compile(REGEX);
        Matcher m = p.matcher(INPUT);
        int count = 0;
            while(m.find())
                count++;
                System.out.println("Match number " + count);
                System.out.println("start(): " + m.start());
                System.out.println("end(): " + m.end());
                System.out.println("group(): " + m.group());
                System.out.println("m.groupCount(): " + m.groupCount());
                for(int i=0 ; i<=m.groupCount() ; i++)
                    System.out.println("group(" + i + "): " + m.group(i));
        }I had the following result:
    Match number 1
    start(): 0
    end(): 25
    group(): <title>Dogs story</title>
    m.groupCount(): 2
    group(0): <title>Dogs story</title>
    group(1): Dogs story
    group(2): null
    Match number 2
    start(): 29
    end(): 40
    group():  [[little]]
    m.groupCount(): 2
    group(0):  [[little]]
    group(1): null
    group(2): little
    Match number 3
    start(): 54
    end(): 61
    group():  [[by]]
    m.groupCount(): 2
    group(0):  [[by]]
    group(1): null
    group(2): byand I realized that:
    - in the case of "<title>...</title>"
    "m.group(1)" was "what I was looking for"
    - but that, in the case of "[[...]]"
    it was "m.group(2)" that I was looking for.
    So, I can't say in both cases, "m.group(1)"
    is what is between either "<title>...</title>" or "[[...]]".
    Can you explain me in the previous example why:
    - in the first case, we have:
    group(0): <title>Dogs story</title>
    group(1): Dogs story
    group(2): null- and in the second case, we have:
    group(0):  [[little]]
    group(1): null
    group(2): littleIn the synopsis: "Returns the input subsequence captured by the given
    group during the previous match operation."
    I do not understand what is meant by "during the previous match operation".
    Thank you for noticing when I'm being illogical or missing the point :/ :) .
    Thanks and all the best,

  • Scanning several photos at the same time

    Is there a way to have several photos or items on the scanner and have them scanned as individual items rather than one composite image?
     I am using the HP Photosmart 5510 and am running Windows 7 Ultimate

    Hello there @anncognito ,
    Thank you for joining us on the HP Forums today, hope you enjoy your time with us!
    I understand you are using the HP Photosmart 5510 with Windows 7 Ultimate. You are wondering if you are able to use the detect separate images software HP offers to have the printer scan multiple blocks of images loaded on the scanner glass at the same time.
    The simple answer to your question is yes. If you have the most recent software available for your HP Photosmart 5510 than you will be able to load different images on the printer scanner and have them scan separately. Once you get into the "Advanced Picture Settings" you should have the option to select your appropriate option.
    This picture illustrates what you will see. Let me know if you need any further help! Look forward to hearing back from you!
