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).

Import edge animate into after effects

Hi, is there any possibility to import a file that is created in edge animate into after effects?

I don't think you can as they are both two different technologies. Understand that an Edge Animate file is really an HTML5 file. The actual stage that is used when creating your Edge Animate file will also import an HTML file.
Maybe one of the Adobe mods can chime in to help.

Edge Animate vs After Effects

I am very new to these tools, so please pardon if this is a ridiculous question. What is the difference between Edge Animate and After Effects? Is one better for web design? Thanks,

If you do not need interactivity, then AEffect is still a great tool to use. If you need interactivity then EAnimate is great as well

Adobe after effects not responding, ever!

I have been having this issue for a long time and cant seem to find a solution, maybe I am wording it wrong, i dont know. It worked just fine for about a year, but now basically every single time I open adobe after effects cs5 it works for about 1-2 minutes and then freezes, the typical "this program is not responding" message shows up with no error code. it doesnt matter what I do or what I click on, it happens every single time! Its really frusterating! my computer has 32 gb, I'm sure that is plenty of RAM. I have done all the updates on the adobe website (including the quicktime updates) I saw OpenGL mentioned many times but I cant seem to find anything like that on my computer so I dont know if that is a problem or not. I noticed on the sytem requirements list (I have a windows 7 professional) they said that the processor must be Intel® Core™2 Duo or AMD Phenom® and my computer has intel (R) Xeon(R) cpu 5160 @ 3.00GHZ 3.00 ghz (2 processors) I honestly have no idea if that would be a problem. If anyone else has had this issue I would love to hear how you fixed it, I have tried so many things chances are I already tried it but still.

okay sorry it took so long, this is my dads old computer so I had to keep calling him haha. so I literally anwered everything, I really want to find a solution!
1) adobe after effects cs5 with the 10.0.2 update
2) on the adobe website it looks like this is the most recent update for cs5 on windows
3) windows 7 professional 64 bit opetrating system
4) intel(R) Xeon(R) CPU, 2 processors, 32 GB of ram, NVIDIA Quadro FX 5800, 2 disk drives, no external drives
5) NVIDIA Quadro FX 5800
I couldnt seem to find anything about CUDA , I googled it but couldnt find anything to tell me how to find out this info, if you know please let me know
6) nvidia quadro fx 5800
7) source footage is microsoft video AVI, with quicktime
8) it was just the typical "this program is not responding, please wait for the program to respond" I let it run a couple times to see if it ever responded but it never did. but the last couple of times I opened AE it just freezes and no message shows up.
9) it doesnt matter what I do, even if I just open it and let it sit there it still freezes up.
10) it worked for about a year, I dont beleive anything major has changed on my computer, but I have been stuggling with this problem so long I wouldnt be able to remember anyways.
11) yes quicktime is installed and updated, it is version 7.7.4
12) I usually dont have anything else running other than AE
13) I asked my dad about this and he said he didnt think so so I assume that means no.
14) yes I have openGL enabled
15) within the first two minutes of opening AE doesnt matter if I am editing, ram previewing, or nothing.
16) I have tried checking and unchecking the "render multiple frames simultaneously multiprocessing" and the problem occurs either way, but right now I am using it.
17) no use of ray traced 3d rendering
18) not an out put problem
19) exact sequence of steps? well... I click on adobe after effects, it opens kinda slower than it used to, then I usually will his ram preview because then I can see when it stops exactly, but I also have tried opening it and just looked at settings or preferences or what not and it would freeze then, or I will click on a diffrent compositions and it would freeze. pretty much whatever steps I take it always happens.

.Max Files in After Effects

We are trying to create a movie with a roving drone. The movie is being created in FCP; and edited in after effects. Beacause we are only doing this for a school project we do not want to pay for any models. My question: Are we able to import .MAX, .3DS or .OBJ's into after effects to include in the final cut?
What is the native file extension for 3D objects in AE? Also I've heard that the 3d invigorator plugin may allow me to bring in objects, but have read otherwise.
Any help or suggestions would be appreciated.

Mylenium is right. Here's more information.

Editing Speech Metadata (Timecodes) in Premiere Pro / After Effects?

I want to edit the timecodes of metadata words in Premiere and find it not possible.
In After Effects, after importing the video file, it now allows me to edit the timecodes, yet
incredibly enough, After Effects cannot let me play the video with both image and audio. People say do RAW preview but I cannot hear the sounds of the video.
It seems I can either hear only audio or watch the video without audio to edit the timecodes of metadata words.
Well, how can I... how can I do properly edit the timecodes of metadata?

I stand corrected. I though it was completely gone. I actually only tried to use it once and the accuracy was so bad that I never tried again.
Out of curiosity I read through the tutorial and found that everything worked for me just fine. I even thought of a great tutorial that could be made for dynamic text animations or captioning.
I'm not perfectly clear about where you're getting hung up. If it's in the section:
Use After Effects scripting to convert speech metadata to Flash cue points
then I have a suggestion for you. Instead of copying and pasting the script to a text editor use the script editor. Just open File>Scripts>Open Script Editor. Then copy only the actual script part between the first { and last } to the script editor. The first line in the script code (#target aftereffects-9.0) is stopping the script from running in CS5.5.
Then, back in AE select your movie layer with the labeled markers, go back to the script editor and run the script. Now check the marker data and the words have been copied from the comment field to the flash cue point field.
The rest of the tutorial should work as expected.
Thanks again for pointing me to the speech analysis tool. It's going to actually save a bunch of time in an upcoming project.

Does anyone have a link to a Adobe After Effects CS3 Trial Download, if so, please help

Hello, and thx for reading
I'm in need of an Adobe After Effects CS3 Trial, there's no way to download it on the original website, because it has been replaced with CS5, and as much as I would've loved to get that, my computer can only support up to a 32 bit resolution, so I cannot install or use CS4 and CS5, that's when I found out that CS3 comes with a 32 bit resolution
But now I can't find a download for the Adobe After Effects CS3 Trial, please help

Why do you think that After Effects CS4 can't run on a 32-bit operating system? It can. After Effects CS5, on the other had, is a 64-bit application.
There have been many threads in which this question has been asked and answered. Please search the forum before asking a question next time. Here 's one such thread, with all of the information that you need: http://forums.adobe.com/message/2951875

"The importer reported a generic error" when trying to import an After Effects file into Premiere.

Currently quite new to using both pieces of software - I'm trying to grab a file, either a save or an export, from After effects into Premiere. I've googled around, but I can't find anyone with a similar problem with it being an AE file.
Just looking for some advice on what to do.

Okay so I've searched around most of this forum and as much of Google as I could find - I have found similar problems, but nothing exactly the same; and none of the solutions I've found have worked for me. I've seen a lot of people having trouble connecting to the DL server on the file-selection window, but I don't even get that far - an error message just pops up in the middle of my screen - and my error doesn't mention a server, just that it can't connect to AE DL.
I changed firewall software (which I've wanted to do for months, anyway) and still to no avail.
As for the "The importer reported a generic error" problem also, I can't find any problems or solutions with After Effects files not being able to be imported.

Importing After Effects document to Premiere Pro errors: "The importer reported a generic error."

I have tryed to save After document several different names and greate new ones. Always same error. Whats wrong in my workflow?

After Effects Presets Mac

Uhm i have have a question: I just made a new admin account on Mac OSX. But after i did that, i tried opening After Effects and got something about license and restart, so i restarted. But it didn't work, so i reinstalled After Effects and i could open it as normal. BUT now i can't find the Presets folder in /Applications/After Effects/. I tried looking in documents but didn't find an adobe folder there either. I REALLY need a Presets folder so that i can add my VideoCoPilot .ffx files in there. PLEASE HELP

I don't actually know if i did a correct uninstall. I just double clicked the "Uninstall" and wrote in my Username and Password. Then it didn't like start opening a script or something, so i just restarted my computer, and when i looked in /Programs, After Effects wern't there. Another thing that is killing me is that if i go into After Effects and go to Effects and Presets and right-click and select "Browse Effects and Presets" or something, it don't open Bridge and let's me find text effects. Now after i tried looking in the directories and if it isn't another way i'll have to format my harddrive. That's how important my After Effects Presets are. :/

I have after effects through creative cloud and I'm struggling to get the puppet tool. I have been told it's free.

In CS6 it's a free and installed plug in, but I can't seem to find it. Again I have after effects through cloud.

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.

I need to manipulate only X values of Edge coordinates (IMAQ Find Vertical Edge VI)

In IMAQ Find Vertical Edge VI Edge Coordinates is an array of clusters, but I need to manipulate only the X values. How can I extrapolate those values to use them after?

Thanks for your answer...I have begin to do it yesterday afternoon, but I don`t finish it yet !!!Isn`t there an other way of doing ? My problem is that I don`t know the exact number of points used by the edge coordinates, and before unbundling the cluster, I have to transform my array of clusters into a cluster, so I have to give it a fixed size...it`s not a difficult work, but quite long...
