After Effects scripting: Serial port access?

Hi,
Does any one know if it's possible to access the computer's serial port using an After Effectsc script?
I'm building a motion control script and I'm wondering if I can use a script to read the values of a keyframed parameter(e.g. a slider effect on a solid layer) to send serial port commands to move my rig.
Regards,
Ihab Ali

I don't think that ExtendScript for AE ships with a way to do that out of the box, but in the Javascript Tools Guide for CS5, there is a section titled "Integrated External Libraries" which reads:
You can extend the JavaScript DOM for an application by writing a C or C++ shared library, compiling it for the platform you are using, and loading it into JavaScript as an ExternalObject object. A shared library is implemented by a DLL in Windows, a bundle or framework in Mac OS, or a SharedObject in UNIX.
You can access the library functions directly through the ExternalObject instance, or you can define an interface that allows your C/C++ code to create and access JavaScript classes and objects.
All Adobe Creative Suite 4 applications support this feature.
So you can probably write an app in C or C++ which communicates directly to the machine's port, and then call functions you declare in that code via ExtendScript. Sorry I couldn't be of much help here, but that's where I would start.

Serial port access time slows in version 6 to 7 upgrade

Hi - I am in the process of upgrading an project from LV 6 to LV
7, the serial port access works well in LV6 but after the
upgrade, the serial port access is slow in LV if the application is
compiled into an exe. We are running Windows 2K on all machines
and have installed the LV7.0 runtime engine on the PC that is running
the executable. If I run the application on a machine that has
the full LV7.0 development software on it, the executable runs
just like it used to under LV6.0
What am I forgetting?? The application is built into one exe that
has all of the sub vi's included. I have checked the box on the
application builder that says included serial port support.
Help! - We have 3000 PCBs sitting in manufacturing waiting to go to test until I solve this problem
Thank you

Hi
I just recently finished a project in which I had to upgrade code from LV 6 to LV 7.1. After I did that the serial port actually worked but all the Fieldpoint devices that were connected to the system didn't work. The problem ultimately was the NI Fieldpoint Drivers. After I installed the newest drivers from NI everything worked perfectly. I don't know why your problem is occurring, but I wanted to reasure you that there isn't a problem with the serial ports when upgrading to LV7.1 (I don't know about LV7).BTW, I had LV6.1 development system installed on the computer, but didn't have the LV7.1 (All I had was an EXE file).
So, try installing the newest drivers. Maybe that can help.

After writing into serial port, the same message gets bounced back into the Inqueue also. If anyone know how to avoid this, please rpely.

If you disconnect the cable going to the serial device, do you still get the echo? If so you have something going on in the port setup. If disconnecting the cable stops the echo then the device you're talking to is doing it - which would be my bet. One thing to check is whether this might not be normal operation. I have seen devices that if a command was successful, it simply echo'd back the command string you had sent. Also many serial devices have setting for specifying whether they are to echo commands.

Low Level Serial Port Access

This question has gone unanswered several times on this forum in the past but I thought I would try it once more.
Is there any Java API that is in, or will work with J2ME to allow direct read and write to the serial port similar to the functionality that javax.comm provides for j2se.
This would be useful for a project where a palmos device is used to communicate with equipment used to monitor industrial processes.

Some MIDP 1.0 devices support access to the Serial
Port.
I have done it with Motorola i85, i50 (iDen) and
Motorola T720i.
I think 95cl also supports it. I'm ALSO having problems with serial port access on
my T-Mobile Moto T720i phone. I've had MUCH success
with the Nextel i85, i50, i95cl, etc phones, but the
same code isn't running on the T720i.
What do I need to do differently???
Thanks,

Infrared / Serial ports access in MIDP for Palm

Hello,
Do you guys know if MIDP for Palm allows to connect to the IR / Serial ports ? If yes, any examples ?
Thanks,
Vadim.

I'm very interested by your discussion, i have searched a lot of information about midp and the access to the serial port.
The specifications of midp says that the comm protocol is not available in midp.
The IBM J9 Java VM is supposed to be full midp implementation but only only for x86 processors. The lcdui package is not available with the J9 VM for palm. The lasts contact i have with ibm about this subject, they said that they will implement lcdui but they can't say when .... perhaps in 2002.
I don't know any other Java VM witch have a full midp implementation ... Kada VM will be but i don't know when ...
If you have any other information, i'm very interested
Thanks by advance

Need faster serial port access

I am using javacomm for serial port communication and the performance is too
slow for my needs. I am comming with an embedded app from an NT machine
with my java app. For benchmark purposes I hava VB app that can also talk
to this embedded app. The round trip communication time for the VB app is
20-30 milliseconds but the java app takes ~200 milliseconds. I think I could
improve performance by writing to the serial port directly instead of going
through the javacomm api which I think is slowing me down. Is it possible to
to a low-level file open and write directly to the serial port? And if so, how?
Thanks,
Michael

MichaelSlowing down of communication process depends upon code content as well. if u can put ur code here, may be u can get some feedback concerned with speed.
you can not directly talk at a serial level but make a component in say C n can use native methods to access that component. But that component would be very much comparable to Win32com.dll.There would be speed difference but that difference would not be enough to warrant 'too much'

WANTED After Effects Script Programer ...

Hello,
I'm looking to hire someone who is capable of programing a script that will enable Adobe After Effects to generate completed product demonstration videos given a collection of video clips, product photos, voice over audio and product data from a spread sheet.
Basically, i would like to be able to layout the video frame with various fields that would be filled with data (text data and file paths) from the corresponding columns in the spread sheet.
This script would function very much like "catalog software" for Adobe InDesign but for video instead of printed material.
If you're capable of this task, please email me at [email protected] so that we can discuss the details.
Thanks,
George Tasick

To my knowledge scripts cannot change projects without the program actually running. Scripts merely call reflections of the internal commands which only are available when the program runs in full. Perhaps some of that has changed in AE CC, but I'm not aware of it.

Default After Effects script location

Afternoon,
Does anybody know of a way that you can change the default location After Effects will look to on startup to find scripts?
What I would like to do is have a scripts folder on the network that all workstations in the studio all use to load scripts on startup. It would make things a lot easier to maintain parity across our workstations and renderfarm.
I'm sure there is a messy way to do it with aliases and / or custom startup scripts, but wanted to check to see if After Effects could handle it by itself.
Thanks

What's messy about aliases? If you jsut put an alias in the default folder that points to your custom folder, everything works fine. I do this for plug-ins and scripts so that I can use the same extensions across multiple versions of the application.

Run after effects script without opening after effects?

I have a project as a template. I want to run a script that injects itself with the project and replaces videos and text depending on the contents of my script file. So far so good, but can I run the script without opening after effects GUI? I use this now: afterfx -r c:\script_path\example_script.jsx. Is it considered best practice to have after effects GUI up and running if going to do many script changes on the template? Basically I am looking for the same functionality as aerender with no GUI.

To my knowledge scripts cannot change projects without the program actually running. Scripts merely call reflections of the internal commands which only are available when the program runs in full. Perhaps some of that has changed in AE CC, but I'm not aware of it.

After Effects Script Issue - Resize

I have a few scripts that have worked flawlessly...until now. Now, when I start the script, the pop up window isn't sized properly...several of the buttons are missing and the one's on the right are clipped. Now here's the kicker. I am running the same version of AE on my desktop and laptop. On my desktop, it appears fine. On my laptop it does not. The only real difference, other than hardware of course, is that I updated AE on my desktop. My laptop was a fresh install.from
I have a purchased script from Conform Studios that behaves similarly.
Any thoughts on what to try?

There is no such thing as a "standard font error". Sorry, that's a dangerous generalization and oversimplification. I literalyl have dozens of font errors in my database and they all come with different causes and numbers, meaning they appear in different contexts/ parts of the program/ with different functions used. Since you did not provide any more info about your system or what version of AE you use, we can't even begin to guess. and just because otehr programs show certain fonts doesn't mean they necessarily show up elsewhere. You could have the same problems in otehr tools just as well, so I'm afraid "find something else" without even trying to resolve the issue is not really a productive way to go about the matter and not doing the whole thing justice. A single "bad" font can make or break a system and things like font managers, printer drivers and even your bog standard graphics driver al lhave to do with accessing and rendering fonts and could influence application programs....

Opening a web browser from an After Effects script

Hi,
This may be a stupid question, but is there any way to open a web browser with a URL from an AE script, other than explicity lanuching the browser app via a sys.callSystem() command?
I'm asking because obviously scripts need to run on both Windows and MacOS, and the user's default/preferred browser isn't necessarily going to be IE or Safari. That and I'd need to find the file path of the browser anyway somehow.
It's to display external help.
Thanks,
Christian

system.callSystem() can launch a URL without specifying the specific app. This code user's default browser. The last line is the main deal, the other stuff keeps it universal for PC and MAC.
//CHECKS FOR USER OS
function osCheck(){
          var op = $.os;
          var match = op.indexOf("Windows");
          if(match != (-1)){
                    var userOS = "PC";// User is on PC
          }else{
                    var userOS = "MAC";// User is on MAC
          return userOS;
// RUNS OS CHECK FUNCTION
var userOSVer = osCheck();
//DEFINES PC OR MAC TERMINAL SYNTAX
if(userOSVer == "MAC"){
          var urlLaunchCode = "Open";//Mac based
}else{
          var urlLaunchCode = "Start";//PC based
//ONCLICK FUNCTION FOR YOUR URL BUTTON CONTROL
//urlLaunchCode = Open or Start / " " = keeps a space character separator / "http://myurl.com" = Defines the actual URL path
myURLButton.onClick = function(){system.callSystem(urlLaunchCode + " " + "http://forums.adobe.com/thread/993523?tstart=0")};

After Effects scripts, split and combine comps

Hi All
I have tried to search but to no avail so I turn to this cool forum to post my question.
We have a charity fun run coming up, and I am part of the team that films the finish line.
We record the finish line, we string the footage together into a comp in AE and we have this cool script that splits the comp up into 30 second rendered chunks. Also it staggers the split, so split 1 = 0 to 30 sec, split 2 = 15 to 45 sec, split 3 = 30 to 60 sec and so on. The goal of this is to create short video clips of 30 seconds were runners can see themselves cross the finish line. We stagger the script so the people who cross the line at say 29 sec can see themselves in the middle of the second clip, rather than the end of the first. Hopefully this all makes sense.
We would like to create a separate video of a logo spinning in, as well as a quick thank you message. We can then append these to the start and the end of each 30 second video.
So to my question...is there a way to create an AE script (or append the existing script) so that as AE splits up the video into 30 second chunks, it appends, say, the same separate 10 second comp (logo) at the start of each, and the same a 10 second comp (thank you for raising money) at the end of each of the 30 second clips?
Hopefully the above makes sense. I am pretty familiar with AE, but not so much the scripting side.
Any insight, suggestions, would be VERY welcome. Also FYI, we have over 1.5 hours of finish line footage, so LOTS of 30 second clips... hence why the splitting script was created in the first place.
Thanks
Lawrence

Sure. Ask on the scripting forum, AEnhancers or hire one of the guys from AEScripts. And I'm sure it might even elicit volunteers if you just provided the code.
