Parent path point to [null] object after effects

is it possible to parent an object or null object to a single point on a shape path? Beam is closest thing I can find but this feels hacky to me, and would be nice to have a fill too.

No way. Even expressions cannot access mask/ shape layer paths.

Vanishing Point filter, export for After Effects (.vpe) is disabled

I am using Photoshop CS6 Extended (ver 13.0). I can apply the Vanishing Point filter to a jpeg still and set/apply the planes but the Export For After Effects (.vpe) command in the drop-down menu within the VP window is greyed out. I understood this filter is a feature of the Extended version. Can anyone help explain why this is disabled? Much appreciate any advice.

Hi, I'm having the same problem...all I want is to create perspective on this chinese temple I've masked out of a background. There are only two planes. Is the VP effect possible on this? Both planes are blue but the export button is still grayed out.

Z-rotation of a 3D element parented to a moving NULL layer: WEIRD behavior

Hi all,
Never encountered this before!
I have a bunch of little 3D elements parented to a null layer that moves along the X axis (for consistent horizontal movement of all elements).
Separate X and Y rotations on the individual elements works great, but as soon as I try Z rotation, I get really strange "planar" rotations. When I un-parent a 3D element, the Z rotation works great...only now it's no longer parented!
What's up with THAT? You can perform X and Y rotation on a 3D element parented to something else, but not Z rotation?? I don't understand this at all.
Anyone have any insights into this?

Thanks Aaron.
I don't know if the fact that the NULL object was scaled had anything to do with this, but I ended up relegating each 3D object to its own composition, and then parented those to the NULL object, which worked.
Probably the long way around, but next time I'll know to look for any scaling issue before I start :|

How to create an after effects plugin using c++?

I've gotten to the point of downloading the after effects sdk. Although I am still lost and other than here, there are very little places where they give you proper information, if any at all, on how to develop after effects plugins using c++.

Dynamiclinkmanager.exe crash on startup: After Effects CS6

Every now and then Adobe Application Manager uninstalls itself for some reason, and when this happens Premiere Pro and After Effects don't work. I then quickly reinstall it and Premiere Pro works fine but After Effects does not. I get this error: "After Effects error: Crash in progress. Last logged message was: <5092> <DynamicLink> <5> F:\Adobe After Effects\Adobe After Effects CS6\Support Files\32\dynamiclinkmanager.exe" and then when I click OK this pops up: "After Effects can't continue: sorry, After Effects has crashed. For After Effects Help and Support...." and so on. I don't know if it matters but at the bottom of this box it says "(0::42)". After that point it says "Adobe After Effects CS6 has stopped working" and the usual pops up. Can you give me any feedback, I don't know what's wrong with it. I heard some things like delete the prefs file and that didn't work. I look forward to hearing from you. Thank you. (and yes, that location is where I have Adobe After Effects installed, my main drive is out of space.)

You need to install After Effects on your C: drive.
Also, you need to install the bug-fix updates. You are running version 11.0.0, not 11.0.4. Updates: http://adobe.ly/DVA_updates

Premiere - After Effects dinamic link problem

I have a timeline with some clips. To stabilize a clip I replaced it with an After Effects composition (called stabilize1). Everything was right and I got a clip stabilized. But I have done this with another clip (called stabilize2) in the same timeline, and when I returned to Premiere, both replaced clips point to the second After Effects composition. The AE file name and composition name are different in both files.
I done a workaround, I created two AE compositions with the clips stabilized and added to PR project. Then I deleted the clips and inserted the AE compositions.
There is a bug, may be?
Regards,
Lluís
Windows 7 64b
CS5.5 production premium spanish
Premiere pro is updated to 5.5.1

OK, let's have some fun further!
1. Place two clips in the timeline.
2. Right-click any of them, choose 'Replace With After Effects Composition', save AE project as e.g '1st Project' and close it.
3. Switch back to PrPro, choose 'Render Entire Work Area' (indulge ourselves adjusting Work Area to dynamically linked comp only).
4. Save PrPro project, close PrPro and then relaunch it with the same project.
5. Right-click another clip, replace it with next After Effects composition, save AE project as e.g. '2nd Project'and close it, switch back to PrPro and choose 'Render Entire Work Area'.
How does that work ?!!

After Effect camera issue Cinema 4d finding object

Hi everyone,
I'm using After Effects CC.
I've imported a Cinema 4d file into my AE composition, and it use by default Cinema 4d's camera.
I've also set a camera in AE parented to a null object.
When i switch from C4D's camera to AE one, my 3d object disappear, i can see the base-grid, but I can't find my object.
Is there a method, to avoid that problem?
I can't find at all my 3d object, i've searched a lot along the base-grid but nothing. Also using Anchor Point, or Position nothing...
I only need to find my 3d object using AE's camera.
Thanks a lot
Michele

Don't parent your AE cam. This is bound to fail. And at the risk of stating the obvious -create a proper 3D camera in the C4D file and assign it as the active view cam.

Find object's edge coordinates in After Effects

Hello,
first of all, I'm sorry if the answer to my question is already posted somewhere … I'm a bit confused I didn't just find one somewhere in the web already—don't know if I perhaps look for the wrong terms or if it's really such a special question I have …
Anyway, my question is: how can I get the coordinates of all four edges from objects (images) in a three dimensional composing in After Effects? And also, is there a way to see the actual coordinates of the camera that I have moved by several parented objects?
In case, this might be of interest, here's a more detailed description of my situation: I have made a little three dimensional composing in After Effects with scaled and rotated images an a moving camera. I want to show the composing within a tablet app and my first plan was to render it and put the movie into the app, but now my programmer and I think it might be better to generate the composing directly within the app. So my programmer needs the said coordinates to rebuild the composing in his code (as far as I know, he uses Xcode and writes the app in Objective-C).
Hope you guys can help me …
Cheers!
Theo
(I use After Effects CC on Mac OS X 10.9.)

Edges/ lines are determined by the coordinates of their end points - basic planar geometry. You can get those by using the toWorld() method and filling in the corner point coordinates relative to the layer anchor point, e.g.:
TopRight2D=[50,-50];
TopRight3D=thisLayer.toWorld(TopRight2D)
Easy as Pi (or pie if you prefer).

Loading JSON files from URLS/File Paths into a After Effects

Basically, I want to make a script in which the user enters a file path or URL of a JSON file, the file is loaded and the user can manipulate the data in various ways within After Effects.
I got as far as writing a script that requests the data and logs it into the console but it will only work in Extendscript. I'm using Extendables which was built for indesign so that may be the problem.
    #include Extendables/extendables.jsx
    var url = "http://echo.jsontest.com/key/value/otherkey/othervalue";
    //Retrieve the data
    function retrieveData(_url){
        var http = require("http");
        var response = http.get(_url);
        var responseStr = JSON.stringify(response);
        var responseBod = JSON.parse(responseStr);
        var data = JSON.parse(responseBod.body);
        $.writeln(data.key);
    retrieveData(url);
When I run it in After Effects I get an error "Undefined is not an object" pointing to line 162 in errors.jsx which says:
if (app.name.to('lower').contains("indesign")) {
What exactly is happening here? Is there a better way to go about doing requesting JSON files?
Thanks!
EDIT: I should add that I tried removing the "$.writeln(data.key);" but am still getting the same error.

The line that generates the error tries to test whether the targetted application is InDesign, and the test is not so good because in other apps the test may generate an error.
(For AfterEffects, the object 'app' exists [object Application] but it doesnt have a 'name' property, so app.name.xxx is wrong).
I don't know of a test that would work for any app. For After Effects, "if (app.effects instanceof Array)" might work, not sure.
If the script is meant to target AfterEffects only you can simply omit the condition.

How can I apply a timestretch to different null objects and then use them to parent layers?

I am using several hundred stills which are held on screen for different lengths of time. Is there a way to create null objects with various timestretch values and then use them to parent my stills?
I'm trying to find an equivalent to the 'paste attributes' function in Final Cut Pro.
Thanks in advance
A

If you have movement on the stills you can set up expressions based on in and out points. That's what I do. I then drop all my stills in order into a comp then set the out point for all stills for the longest duration. I then set group colors for layers that I want to make different lengths, do a group select and then adjust the out points for those layers. When I'm done I sequence the layers using the keyframe assistant.
The other way I work is to use an audio track with markers for timing. I have an expression that reads the markers and sets opacity for the layers based on pairs of markers. The motion is also controlled by expressions. That's an even faster way to set up an animated slide show.
The last way I work is just to set in an out points for all layers, sequence the layers, use expressions to do the motion and then use time remapping on a pre-comp to adjust the timing of the slide show. All methods are quick and easy.
Here's a fly in bounce and then drop out fxx preset that will give you an idea of how expressions based on in and out point work for slide shows. You just drag the layer to it's resting position, apply the animatiokn preset and the layer flys in, bounces, and then drops out the bottom of the comp. Works in 2D and 3D space.

After Effects video cue point data error #1107

Hi all,
I'm trying to create a personalised video using the techniques described here: http://www.adobe.com/devnet/flash/articles/atv_personalized_video.html
I have created the video and tracking data in After Effects (CS5), converted the tracking data to Flash cue points and exported the .flv file. I can import the video into Flash (CS6) just fine and I can see all the cue point data however when I try to compile the Flash project, bearing in mind this is just an empty stage with an instance of FLVPlayback on it, I get the following errors:
VerifyError: Error #1107: The ABC data is corrupt, attempt to read out of bounds.
ReferenceError: Error #1065: Variable Icon is not defined.
ReferenceError: Error #1065: Variable FLVPlayback is not defined.
ReferenceError: Error #1065: Variable Main is not defined.
If I export the .flv without the cue point data I can import, compile and play the video without error.
I've had a look around and I've not really been able to find any information about this issue and don't have a clue where to start with it.
Any ideas?!

        var cont = false;
        // loop through parameters
        for(param in params) {
            // I added this conditional to strip out markers in my project which were superfluous
            if(params[param] == "410,230.5") {
                var cont = true;
                continue;

Help with After Effects? Null Layer and Text not working?

In after effects cs5.5 on mac, im motion tracking as normal, and the track works fine, then when i add the null layer and edit the tracking target to the null layer, the screen goes black, and all i can see is the null layer as a red box moving along the motion track path (i cant see the path) also, whenever i try to add text, (which im trying to motion track via attatching to the null layer) the text is invisible, when the screens black, all i can see is the wire frame of the text next to the square null layer, im pretty new to after effects, but im following tutorials as i should, and its just not working as it shows in all the videos ive tried, please help!

Check whether you have wireframe mode enabled/ Live Update disabled. Sounds like one of those cases. Other than that this could be OpenGL issues, so turn it off in the prefs. Also check your comp size vs. the size of the footage you are tracking. Tracking works relative to the layer, so if the comp is too small, the values would be so large they end up being outside the comp.

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.

FR: Ability to move entire Motion Path (as in After Effects)

If you like this Feature Request, please copy/paste on Adobe's Feature Request page to get your voice heard: www.adobe.com/go/wish
*******Enhancement / FMR*********
Brief title for your desired feature: Ability to move entire Motion Path (as in AE)
How would you like the feature to work?
The same way it currently works in After Effects: ability to move an entire motion path by selecting all of the motion path's keyframes before click-moving one of the selected keyframes in the Canvas/Program Monitor.
Why is this feature important to you?
This feature makes it so much more efficient to move a motion-animated asset to a new location without inadvertently changing the motion path. This tremendous workflow efficiency works wonders in AE and could work equally well in Premiere Pro.
