Null object not following 3D camera tracking points.

After applying the 3d camera tracker I right click between three targets and select "create null and camera", this creates a null object correctly aligned with the selected target and a camera, however, when I scrub through the timeline the null object is not tracking along with the selected target in the scene, it just stays in the one spot on the screen. It only just started to have this problem, it had been working fine before and all of a sudden its not working. Is there a way of fixing this? Did i accidentally deactivate the feature some how? Cheers Luke.

I'm not sure I follow your description. When you say the null does not track with the target, that would be correct if the target is something that is moving in the scene because the 3D camera tracker solves for a moving camera solution by analyzing the change in parallax of fixed geometry in the scene. IOW, it's looking for things like buildings and roads and rocks that do not move. The camera is then added to the scene and 3D object you add to the scene should stick to the plane in the scene where it was placed. In other words, if you stuck a null to the sidewalk or to a wall, the null would stay stuck to the wall.
If, on the other hand, you want to attach a null to something moving through the scene, like someone walking or a car driving, then Camera tracking is not the right tool. You need to use AE's motion tracker or Mocha to track the moving object inside the scene. That tracking data is what you must use to attach a null, or a layer, or text to something that is moving through the scene.

3D camera track points not displaying correctly

Just bought a new iMac and am re-installing all of my programs including Creative Cloud programs. I am having an issue with After Effects not displaying all the track points when I use the 3D camera tracker. I get maybe 6-10 points displaying but that is it. They are there because I can still create nulls, solids, shadow catchers, etc... but the points themselves will not display. I have used the camera tracker in the past with no problems at all. Any idea why this would be going on? Here are my iMac specs...

Try some of your older footage. Some footage produces very few tracking points, other footage produces a lot. Sometimes you need to scale up the size of the track points to see more of them. A screen shot would help us diagnose your problems.

Camera tracked points not showing up

Hey.
I am familiar with the built in Camera Tracker in After Effects and I have had no problems with it up untill this point.
My problem is that after the 3D Camera Tracker is done analyzing the frames, the track points does not show up on the screen.
If i check on "Render Track Points", they do show up, but when i check it off again, the points disappear again, so that doesn't help me at all.
I got 8 gb ram and a decent graphics card.
Does anyone know a solution to my problem?
Thanks in advance.

Are your view options set to show layer controls?

Null object not centred, why?

Create a null object and it's not centred to its location. Why?
Seems like that would be the most obvious position to put the visual representation of a null object. So the least likely place for Adobe to put it?
Or is there some logical reason?

Rick, all other apps that have Null objects use them far more wisely than Adobe does. Mylenium has confirmed my suspicion, that these things weren't thought through, simply created (probably in a panic or out of laziness) as a half way house to what Null objects actually can be.
I get your point about the anchor point, but that's not what I'm talking about. In ALL other apps with a Null object, the visual representation of that Null object is centred. There's a tonne of reasons to do that, and I'm not contending the placement of the Null objects "anchor", it's in the right spot. It's the visual representation of the Null object that's utterly wrong.
That it's a deformable visual representation only compounds this problem.
Your usual presumptuous assumptions.
The null object was a remarkable improvement over how, in the olden days, we created invisibly small or transparent objects to do roughly the same thing.AE's were the first nulls I ever encountered. I learned how to use them when introduced and never really thought about how they might have been better. AE's nulls made perfectly good sense to me. And I don't use the other applications you are alluding to so I don't really need AE's null to be any different. I have, more than once, moved the null's anchor to its geometric center to help my project contributors grasp the concept. But they had no prior experience with nulls, either, so once they got it, I moved things back to their default because that works for me. Why are you still using After Effects?

Objects not aligned in output power point as in project xcelsius2008 sp1

Hi everybody,
I need help...
first of all, apologise me for my english...
my principal problem is to create graphics with a legend that can be interactive with the line of the graphic... is there a function about this?
The only thing I've found to solve my problem is to create many switches buttons and put them over the legend's label, but, when I try to export to PPT this objects are not aligned with the legend's text so the result is not useful and with a bad look...
I've tried to use ceck boxes located near to the legend baut happens the same problem.
If I export in html it works properly... but I net the power point..
Thanks very much
I hope someone can help me...
Maurizio

Hi Javier Jimenez,
thanks again for the new suggestion!!
in effect this could solve my problem cause the trasparency doesn't let to see if the new icon I put over the legend's icon is not perfectly aligned!
in Italy we say : "It was the Coloumb's egg!" .. it means that if I'd thought enough, may be I'd have solved the problem by myself...
Thanks again!
If I can take advantage of you, the big problem for us is the heavyness of our swf inside ppt....
I'll try to explain..
excel file inside the project has 837 cells to be used for my graph (13 item in Coloumn x 65 item in Rows)
this because we need to create a graphic to be able to show a trend of about 2 years, which increase (filling the empty cells) every month...
so many informations, so many objects (icon, etc) tell me, is too much isn't it?
because when I've exported the file in ppt, every time it takes 1 minute only to open that chart...
is possible not to include the excel? could be a solution to take the information from an sql DB ?
thank you very much!
Maurizio

Smart Object Not Opening in Camera RAW in CS6

I've converted a JPEG to a Smart Object in CS6. When I double-click on the Smart Object icon in the Layer, it opens as a separate JPEG file. What do I need to do to get it to open in Camera RAW as Russel Brown does in this video?

JJMack might have been referring to the script and video that is on the script page i linked to.
I did not know about the script. I just knew that ACR can only work on Camera RAw Files and convert the camera sensor RAW data into RGB Images and use setting other then ones set into the camera, ACR can also process Jpeg and Tiff files however Camers Sensor RAW data for thes images nolonger exists in the file. So ACR can not work on the images as well as it can when it has access to the Camera RAW data.
I was somewhat wrong about not being able to edit normal layers in ACR this script sort of makes that posible. What it does is save information about the layers transparenct and layer mask save out the layer as a temp Tiff file and place it back in as a smart object and restor the best it can any layer mask and transparency. You preferences must be set to open Tiff in ACR. While I was somewhat wrong I was bassicly right. The script turns the layer into a Temp Tiff file and places it back in the document as a smart object layer the embedded object is a Tiff file. The temp Tiff file is nolonger needed for the smart object layer has a copy of it in its embedded object.

Functions in script objects not being recognized after certain point

Hi all,
I'm wondering if anyone has figured out why after normally about 300-500 lines of JavaScript in a Script Object, sometimes the functions near the end are no longer recognized by the XFA processor when referenced ("TypeError: Scripts.myFunction is not a function").
When reordered, further up the script object, they work as intended. The line at which it no longer recognizes functions also isn't always the same and I have worked with some script objects that have over 800 lines with all the functions still working.
I've tested in Designer 9 and 10, Reader 8 9 and 10.
Please at least let me know I'm not the only one. I knew of one other developer that had come across the same issue.
Kyle

Thanks radzmar!
JSLint didn't find anything but it set me on the path towards looking for syntax errors. I deleted code in the script object line by line until I narrowed it down.
Turns out it is Regular Expression literals, in particular trying to escape (\) the metacharacters ($.{}[] etc).
For example, var reg = /\}/; should technically match any right-handed curly brace, which in fact it does! The function that it is in works perfectly but every function written below it is not recognized by the XFA processor. Just out of curiousity I tried reg = /\{\}/; which matches {} and all the functions below now are recognized. It seams as though, even though using the escape character is allowed in core JavaScript, the processor sees it as a syntax error because it's not terminated.
Anyways, the easy fix is of course using the RegExp constructor var reg = new RegExp("\\}"); but I'll miss the confidence I had using Regular Expression literals.
Thanks again for the nudge in the right direction.

AE CC 2014 Camera Tracker Not Allowing Me To Create Nulls From Track Points

After Effects CC 2014
iMac OS X Version 10.9.5
Pro: 3.2 CHz IC i5
32 GB 1600 MHz DDR3
NVIDIA GeForce GTX 680MX 2048 MB
I have been trying to use AE's camera tracker for two days and while it will track, show the track points, and even create a camera... It will not allow me to right click the track points to create nulls and it will not show any of the plain targets. My work around was to upload my footage (Red Epic footage) to the older AE CC, re set up all my ins and outs, track the footage, save it, and open it up back in AE CC 2014. Then it allows me to create track points and such.
Great that I found a work around but takes so much time. Please help me if you can. Thanks!
Chris

There is obviously some bug regards of resolution of tracked footage, because if you precompose e.g. Epic 5K footage to HD comp and camera 3D track this comp then all works OK (points are displayable, selectable and camera is "addable"(?)).
But I don't know "trigger" resolution value, when it works, and when not.

Camera tracker solving without errors but not showing result points

hi
I am trying the new camera tracker in AE cs6,
im using very simple shots that can be tracked easily,
and im having some strange behaviours,
basically in many shots the analysis takes places with no errors but after the camera solve no result points appear, even if i use the advanced mode , changing all other parameters etc, and no errors are reported anywhere, also i select the effect on the panel and i also make sure the points size parameters are scaled up,
but if i click on processing points (the unchecked box below 3d solve) i can see they are all there, and i can also create camera and the camera is created, so its as if all the process takes place correctly but for some reason the solve points are not shown on screen
it has happened to me that with same shot sometimes they appeared and sometimes not, but most times they dont
what can be happening in here?
thanks so much

will try to explain better my problem
if i click on
Render Track Points
i can see there are great track points that follow all the movement perfectly,
and yet without checking that box no solve points appear, even when i select the effect on effects panel
or change any other parameter or do the advanced mode
i can still click on create camera etc, but i cannot attach a text etc to a specific solve point because no solve points appear
and yet as i say, if i click on the Render Track Points box i can see great tracking points all over the place following the action
so the fact that selecting Render Track Points on effects panel shows great perfect points following all , does that confirm that camera solve was successful?
i just cannot understand why i cannot see any solve points that i can interact with
i have tried to scale sizes all the way up, select effect on panel and hundred other things
thank you for any help

The following error text was processed in the system IDS : Access via 'NULL' object reference not possible.

Im getting the below error , actually recently i created my own custom table zstudent, later i wrote select query to fetch data from the same and dump at internal table and then bind this to the table node.
But im getting below error, even i removed the select query still same error is occuring.

Thanks Rama,
Acutally i accidentally commented the lo_nd_student = wd_context ....etc
this line was commented .
i have one small requirement to fetch data from local customised table and fill the same to internal table and bind that to table node.
my table node is student having attributes as name , city and number , all are of type strings.
now i created one custom table zstudent having ID - char of length 10,
name of type string
city of type string
num of type string
i have inserted records
but when i use select query to fill data from this zstudent to my internal table of type lt_student type wd_this->elements_student ,
im getting same above error.

Merging C4D 3D objects with AE camera tracked video

I am able to use CC AE's camera tracker track video, create a ground plane, targets, nulls, etc., and get objects created within AE to move along with the camera movement of the video that was tracked.
However, after I create a C4D "layer" (file), I am unable to align the 3D space of the C4D scene with the 3D camera generated by AE's camera tracker. After matching the position and perspective in C4D, the 3D object remains static and disregards any movement in the video. Selecting either the "Centered Comp Camera" or "Comp Camera" makes the C4D layer shink to about 1/20th of its size compared to the "Cinema 4D Camera".
Can anyone suggest a comprehensive, clearly explained tutorial on how to merge C4D 3D objects with video footage in After Effects?
thanks!

You start by running AE's 3D camera tracker on your footage. Then you select tracker points and set the ground plane and origin. Then you either select another set of tracker points or use the same set to create a null and a camera or a solid and a camera.
Now you go to File>Export>Cinema 4D exporter. Save the File. You will get a C4D project with the Ae Camera and any other 3D layers you included in the comp.
Now add your elements in C4d and then import the C4D file into AE. Drag it to the timeline and select use comp camera.
That should do it. It's prety easy if you follow these steps.
If you created the c4D file first, then tracked the footage, you have to select Comp Camera in Cineware, then extract the comp camera in Cineware, then re position your elements inside c4D. This can be done but it is much more cumbersome.
I hope this helps. Just make sure that Cineware is always using the comp camera and that youare using the 3D Tracker Camera from AE in C4d when you are trying to arrange your scene.
Grayscale Gorilla has a tutorial that kind of shows you how to do this. They miss setting the origin and ground plane and there are much more effecient ways to arrange objects in the scene, but it should give you an idea of how this works. The best part of the tutorial is on lighting and color matchin inserted 3D objects.

I can get my report with saved data to work just fine in the DHTML viewer but I keep getting the following error every time I try to view it in the viewer: 
 
'bobj.crv.params.FlexParameterUI' is null or not an object 
 
For testing purposes, I tried the samples available and this is what my results were: 
 
1. Java_CRJ12_Web_Set_DB_Logon sample works fine. I edited the index.html to include my report (without saved data) and it successfully generates a PDF export which it prompts me to open or save. So this works fine and I verified the data in the PDF document. 
 
2. Java_CRJ12_Web_View sample fails with the error I've mentioned above. 
 
This is code I'm using 
jrc_view_report.jsp

Things I know: 
- web.xml appears to be configured correctly 
- CRconfig.xml appears to be working as well (as my PDF document looked good 
I'm using these crjava libraries: 
http://downloads.businessobjects.com/akdlm/crystalreportsforeclipse/2_0/crjava-runtime_12.2.204.zip 
 
I don't think my markup formatting came through correctly - sorry about the code format.

Hi Ted!
Thanks for the reply and suggestions. I don't know if there is a different version of the viewers folder that I should be using but I am using the ones from this folder:
C:\Program Files\Business Objects\Common\4.0\crystalreportviewers12
That said, I didn't see anything amiss in Fiddler and when I looked in Firebug at the script portion where it was constructing the FlexParameterUI panel, I could see where it was capturing the report parameter names and prompts. I decided to rip out all the parameters out of my report and voila, it loaded up fine in the viewer.
I then added a new string parameter giving it a simple short name (Test1) and, initially, I did not use this parameter in the report. It loaded up in the viewer just fine too.
I then added the parameter to the report header and I was back to the same problem - it would not load in the viewer and the error was the same as the subject line shows.
For the record, I am using Crystal Reports 2008 v12.2.0.290
So is there some other crystalreportviewers12 that I should be using?
Kind regards,
Evan
