How to I motion track between changing scenes

Hi i want to motion track heads on to people but the camera keeps changing back and forth scenes. i would like to do this in motion, but i do have FCPX and Adobe After Effects if there is a way to do it there.

I'm not sure what you mean by "changing back and forth scenes", does it cut between scenes or pan back and forth? Since we can't see your footage, it's hard to give specifics, but here are some ideas:
-Break the shot up. Use in and out selections and anlyze in sections.
-Use the offset track option. After you track a "good" section, when the tracker fail (or you stop it) check the Offset checkbox in the Inspector. then find something that has similar horizontal or vertical movement from your subject, which should be at about the same distance as your subject, repostion the tracker and continue to analyze.
I would really suggest reviewing the documentation on using the tracker. If you can be more specfic about your shot, or post a sample, we might be able to give you better suggestions.

How do I motion track just like the Plugin CameraTracker 1.0?

On the plugin CameraTracker, it automatically detects points that can be motion tracked, and it does it very well. What got me thinking, is that it also carries on tracking when a tracking point goes out of screen.
Here's an example:
I am using CameraTracker. As you see, this is the beginning of the clip, and what happens in this scene, is that the camera just fly towards the jungle.
If you see "Hehe", there's a green cross, and that is where the "Hehe" is tracked to. That red box is the null object.
Okay, so when the camera is flying towards the jungle, it passes that green point. And as it passes, it does not stuff the "Hehe". That "Hehe" stays in place as if it was in this Minecraft world.
It says in place, even though the cross has gone out of place.
BUT, if I use the Adobe After Effects built in motion tracking, and just want to select that point where the "Hehe" is, and I begin tracking, it goes pass then green cross, then that tracking box goes everywhere.
How do I do this so it's like CameraTracker? I want to do this using the default After Effects Motion Tracker.
If you cannot understand what I'm trying to explain, let me know what part you don't understand.
thanks.

Could you give me an example of "where you stop the track then move the track point to another spot in the image", using my picture?
What's the difference between CS6 Camera Tracker, and CS6 Motion Tracker?
And for the Camera Tracker plugin, I can only seem to track ONE part. If you see the image, the words are like in one part of the scene. If i were to put a word in a tree, it would look stuffed up. The word wouldn't be tracked onto the tree. It would be tracked on the sand instead.

How to get Motion Tracking Mode to work?

How do I get "Motion Tracking Mode" to work? I click the icon and nothing happens, its like greyed out.

scouterbsa
Here is my check list for you to review regarding using Motion Tracking Mode in Premiere Elements 10 on Windows 7 64 bit.
1. You need a video and with enough motion in the object in it to track it. Color contrast between the object and its background can be important to success.
I created a DV AVI 4:3 in which I have a circle moving, and I have used a butterfly Clip Art from Premiere Elements 10 to track to track the circle as it moves in the video. In this example, you see the object only at 0 time.
2. Select/highlight the clip on the Timeline. And then click on the Motion Tracking Mode icon above the Timeline.
You should next see the following Motion Tracking dialog asking for a Yes or No to the question "Run
Auto-Analyzer to track moving objects?" Click No.
3. At this point, you will see a bounding box on screen. That bounding box should be placed using the mouse cursor on the object
that is going to be tracked, in this case, the circle. Resize and position the bounding box accordingly.
4. Once you have the bounding box on the object and resized, click on Track Object at the top right of the monitor.
The screenshot below shows only the before clicking Track Object at the top right of the monitor.
When that action is finished the bound box edges will be an orange yellow color. I have skipped over a screenshot
for the latter.
5. With the orangel yellow bounding box in place, next drag the Clip Art (in this case, Butterfly 02) from the Clip Art display area toward and into the orange yellow bounding box frame. The orange yellow bounding box frame will turn blue. That is the first sign of success.
Hit the Enter key of the computer main keyboard and watch the results. The Butterfly should track the circle's
movement in the clip. The duration of the clip and the continuity of the object's motion in the clip can be other factors.
If you do not succeed, try again with a different video clip (one with more movement and color contrast.
The above is a best case scenario. If it is speech bubbles that you are having problems with as well, we will deal with them next.
Right now it seems like you are having problems getting started rather than having a problem with a specific Clip Art that you are
using to track the object in your video.
We will be watching for your results.

Probably Stupid question, but - how to remove motion tracking from a clip?

I've been playing around with the motion tracking feature, and think I may have come up with a way to make it work to highlight my now infamous "football"
However, I need to delete the motion tracking effect (s) that I've added to the clip so that I can start fresh. I cannot for the life of me figure out how to delete it!
This may be a very elemental question - and I apologize, but I cannot find the answer. I just cannot delete the original yellow tracking boxes -
Thanks in advance for your help!
Kim

To remove the Motion Tracking, just delete the graphic you attached to it. There's no need to remove the Tracking Object itself.
Although you can if you'd like. Just click to select the clip and then click on the Motion Tracking tool. Then right-click on the blue or yellow squares and select Delete.

How do I motion track a facehugger?

Hi guys, girls, anyone else,
I've made video footage of me shaking around like I have a facehugger on me. I also have a facehugger model in maya. I've heard about motion tracker software and I'm happy to incorporate it, so anyway I was wondering if anyone had any quick tips or advice on getting the facehugger composited correctly onto my face. I was thinking about first attaching the facehugger to a model head and then painting it green to remove in AE later. My main reason for thinking this was that (as well as a front shot) i have a side view shot of me being attacked by it, so in the side shot i don't the legs furthest away showing...
I'm a total newbie to after effects so any help would be appreciated
Thanks
Rory

That's not an easy task, especially for someone just starting out. It involves motion tracking, possibly 3D camera tracking, bringing the motion of the camera into Maya and occluding any parts of the mask that would be hidden by your face, then composite the two together. This is not something that can be covered in a single post. This would be more like a 10 page white paper. Basically, you track the face, import the tracking data into Maya, mimic the lighting in the shot in Maya, and then overlay your rendered mask with your footage.
First, you must get very familiar with AE Basics. Go through as much as you can. Then you need to read up and watch tutorials on motion tracking in AE and Mocha. There are lots of Mocha tutorials on the Imagineer site. You need to learn all about how Mocha tracking integrates with AE, how to track, how to mask or do roto. You'll also need to learn a lot about After Effects motion tracking to understand the process . Once you get a handle on that you can start doing some basic compositing. Look at tutorials like this one on Face Replacement or this one on eye replacement. Those should get you started.
Get to the point where you can do something like either one of the last two tutorials and then start poking around the Maya forums to learn how to insert a head in your mask and render only the front side (facing the camera view), add motion tracking data from AE or Mocha, or any of a dozen other tracking programs, to Maya, and then you'll be ready to start working on your actual project. I'd guess 10 to 20 hours minimum of research and experimentation and you will be ready start on your project. If a client came to me with this kind of project I would tell them it would take about two days in post per 10 seconds of footage to pull off a believable shot like the one I think you want to do. VFX of this kind are not and never will be a simple 1 click 1 plug-in solution.

Motion 3 - Motion Tracking and Match Move

Hi, I have no problem learning how to use motion tracking or match move because there's plenty of tutorials online. My question is, if let's say i motion tracked a clip to my original clip and half way through the movie an obstacle comes into the position where my motion tracked clip is. How do i make is so the obstacle appears in front of the motion tracked clip?
For example, take apple's motion 3 sample video.
http://www.youtube.com/watch?v=BwezKN_hFF4
The place where they put the GPS clip, if while the girl is driving she moves her hand in front of the GPS. How would we make it so that her hand appears in front of the GPS not behind it?
Any help would be appreciated,
Thank you

If I am understanding you correctly, it sounds like you are asking how to have an object that is part of the background layer appear in front of an object that you are going to composite in an match-move.
The only way to do that is to duplicate the background layer and move it in front of the layer you are bringing in, then create a mask around the portion of layer you want to keep (in the example you provide - the girl's hand).
You would have to go frame-by-frame and animate the mask to follow her hand - very time consuming but I don't see any other way.

Motion tracking help

Hi all, hope everyone had a great Xmas.
I am having an issue with motion tracking and I will try my best to explain my problem as clearly as I can
Here is what I am trying to achieve.
Please visit this youtube video Canon Powershot SX30 IS -140X Moon Zoom Test - YouTube
and this is a still shot I just quickly edited in fireworks to show you the effect I am trying to achieve
http://img845.imageshack.us/img845/3148/motion.png
As you can see in the video, some parts of the moon go out of screen in some shots and the camera also zooms in and out of the moon, so I need the word "Business" and "logo" to increase and decrease in size in proportion with the moons size ( camera zooming in and out ) whilst remaining at the exact point on the moon ( as if the word "business" was built on the surface of the moon )
Which tutorial might help me? or if someone would be kind enough to explain how to do this, it would be greatly appreciated
Thanks in advance

Don't even bother to work with that video. Reshoot it. Next time, use a tripod and make sure the shot is consistently exposed, which at the moment, it is not. You apparently haven't even considered the problems trying to match your AE work with the camera auto iris.
And since he put it so well, I'd also like to quote Bogesian from a different thread, responding to someone who also knew little of AE, and wanted to learn what he or she thought would be a simple trick:
"After Effects is a kitchen. It's not a cookbook. And there is much more to using this metaphor than putting a frozen entrée into the microwave.
You have everything you need, it's just not given to you as a recipe for that specific effect.
The AE help system and the many tutorials that came with After Effects will show you how to animate text.
You will need to learn how to use motion tracking in the same way.
You may need to learn how to use the planar tracking system, Mocha, which is not for the faint of heart.
Like learning to make soufflé, you need the basic tools, fresh ideas, high quality ingredients and sufficient fundamental experience with all of the toolsm, techniques and ingredients. You will fail many times. Once you've discovered certain truths and universal, reliably repeatable steps, anything is possible within the kitchen.
Suggest you invest in ayof the many AE books by Trish and Chris Meyer or visit their website for several hours before you attempt to use the more advanced resources you can easily find online."

Tracking records change made by another user or session

How does oracle forms track records change made by other user or session?

I think the question is, how does Forms know to issue the error "FRM-40654: Record changed by another user. Re-query to see change".
I don't know exactly how Forms knows this. But in the past I have found that if a column has changed on the record, which you are not querying in this forms block, then you don't get the error. So Forms is perhaps comparing all the database values for the queried record, against the values that Forms has queried?
When you attempt to lock the record from Forms, you'll see that Forms issues a statement
SELECT <all the db columns in the block>
FROM <wherever>
FOR UPDATE OF <all the db columns in the block which are not query only>
Even so, in the database, that statement doesn't know what the values are that the Form has already queried. So Forms must be doing something else.
Hope this helps, it's a bit of a black box area I guess.

Some questions about how to change scenes

i have something like the following:
fxml (view/main/MainMenu.fxml):
<Scene fx:controller="view.main.CtrlMainMenu" xmlns:fx="http://javafx.com/fxml" stylesheets="view/main/main.css">
    <GridPane xmlns:fx="http://javafx.com/fxml" alignment="center" id="backgorund" hgap="10" vgap="10">
        
        <VBox spacing="8" GridPane.columnIndex="0" GridPane.rowIndex="1">
            <Button text="Start" onAction="#Start"/>
            <Button text="Options" onAction="#Options"/>
            <Button text="Exit" onAction="#Exit"/>
        </VBox>
    </GridPane>
</Scene>main loop (cotroller/main.java):
public class main extends Application{
    public static void main(String[] args){
        launch(main.class, args);
    public void start(Stage stage) throws Exception{
        stage.setTitle(CtrlLanguage.get(CtrlLanguage.TITLE));
        CtrlMainMenu main = new CtrlMainMenu();
        Scene scene = main.main();          //don't know how to make Scene scene = (Scene)FXMLLoader.load(getClass().getResource("MainMenu.fxml")); work on here since MainMenu.fxml is in view/main while the main class is in controller and ended up putting CtrlMainMenu in the view although is not very correct
        stage.setScene(scene);
        stage.setWidth(1080);
        stage.setHeight(720);
        stage.show();
}view controller (view/main/CtrlMainMenu.java):
public class CtrlMainMenu{
    //other buttons actions
    public Scene main() throws Exception{
        return (Scene)FXMLLoader.load(getClass().getResource("MainMenu.fxml"));
    @FXML protected void Start(ActionEvent event){
    @FXML protected void Options(ActionEvent event){
    @FXML protected void Exit(ActionEvent event){
        System.exit(0);          //is there any other way to finish the program than using a system.exit?
}got few questions currently:
1. i'd like to be able to keep using CtrlMainMenu for other buttons while the ones that appear there go to the main (since will be reusing those classes from other scenes)
tried adding fx:controller on panes instead of the scene, but it doesnt work at all (it crashes) else directly in CtrlMainMenu change the scenes of the stage, but then, i have to send the stage to every controller i use? (or how do i know the stage of the scene?)
and in the case of options, i'd like after done, go back to the previous scene, is that possible? if so, how?
2.if i want to implement languages, how do i do to change the text? tried with setText() but depending on where do i put it, it crashes, so dont know where do i have to put it
3.im doing a game that may have different number of players, so, is there some way to erase/hide/add data from a gridpane with fxml?

1. ok, found the way to change scenes, with this way:
@FXML protected void Start(ActionEvent event) throws Exception{
     Node node = (Node)event.getSource();
     Stage stage = (Stage)node.getScene().getWindow();
     Scene scene = (Scene)FXMLLoader.load(getClass().getResource("../view/main/MainMenu.fxml"));     //this is just an example, will change to go to another scene
     stage.setScene(scene);
     stage.show();
}but now i have another problem, when i click on the button the stage scene is changed, but the scene is transformed to a very small one at the top left (the size seems the same as when i dont put the set width/height on the stage when creating it), the stage size remains the same, and when i resize the window, it gets "repaired"
the options, i thought on using a pane over the current pane so this way instead of going back would be just removing that new pane, would that work well?
2. found about languages that is by using <Label text="%myText"/> and java.util.ResourceBundle but don't know how to use it, can someone provide me an example, please?
3. still haven't looked on it...

How to track the changes at report level

Dear Team ,
Could you please help on below scenario.
1.Is there any way to track the changes for each report wise ? Does it possible using the audit database?
2. how to get list for report names by each folder wise( public folders) ?

How to track the change of an asset via field ANLC-KANSW?

I'm trying to track any change to the value of an asset.
I'm looking at field ANLC-KANSW.
I'm not sure how to do it, but if you change the value of an asset, the change is not reflected in the field itself, but other "cumulative fields in ANLC. The change did not register anywhere in CDHDR/CDPOS.
So, anyway to know if the value of the asset has changed?
Thanks,
Jeff

Hi,
if you post to the asset a anep-line is created.
If you make the fiscal year change the ANLC line is created. This ANLC line is a sum of the ANEP's.
Post to the asset and watch the ANEP:
ANLN1 GJAHR LNRAN AFABE ANBTR NAFAB
..and in the ANLC:
ANLN1 AFABE KANSW ANSWL
