Question

Is there a way to play an mp4 file at the beginning of a published project only when the project is accessed from a specific site?
A little background info. I use Captivate 7 and currently have over 100 projects that I maintain on a quarterly basis. I publish using the SWF format and upload the swf/htm files to a server where they are then accessed from a few locations (within our online documentation, in our software product, on two different websites). Many of the projects are linked so some will be viewed as a series and others viewed as a standalone video. Each video uses the same template and includes an intro and end slide. Now my organization wants to implement a new intro to all videos (those I publish and those from several groups across the organization). My current intros provide overview material for the specific video so the new intro, which is an animation with audio in mp4 format, would need to be placed at the start of each project. The issue is, the intro adds 9 seconds to every video and in many cases doesn’t add any value (say, if a user accesses the video from within our product or views the videos as a series). I’ve talked it over with my boss and we want to try to add the intro only to videos accessed from site X, not any other location. So now to my question. Is there a way to play an external mp4 file (intro) only when the published project is accessed from a specific site, therefore eliminating the need to update each project? Maybe there's a way to add a parameter or variable to the URL or the html code?
Thanks in advance for your suggestions. Please let me know if you need additional information.

AimeeLove,
I have a solution for you.  You may have to modify the code a little bit based on how long the timeline animation is for your clock.  I based mine on 3 seconds to complete a minute hand sweep around the clock.
Milliseconds for each point on the clock:
12 = 0
1 = 250
2 = 500
3 = 750
4 = 1000
5 = 1250
6 = 1500
7 = 1750
8 = 2000
9 = 2250
10 = 2500
11 = 2750
In the mouseover section for 12 o' clock, put this code...
myVar = setInterval(function(){
     var pos = sym.getPosition();
     if (pos > 0 && pos < 50){
          sym.stop(0);
          clearInterval(myVar);
},10);
When you point to the time, the setInterval method loops every 100th of a second and checks the current position of the timeline.  When the timeline reaches the range between 0 and 50 milliseconds (almost impossible to hit 1 specific point), the timeline will stop at 0.  Also, the clearInterval will be fired to stop the loop.
In the mouseout section, put this...
sym.play();
clearInterval(myVar);
It start the clock again, and it also clears the loop in case you mouseout before you reach the range.
Make sure that myVar is a global variable so you can clear it from the mouseout section.
Repeat this for each point on the clock.  To avoid potential conflicts, you may want to use my12, my1, my2, etc. instead of myVar.  I put the milliseconds at the top that you would use as the beginning of the range.  50 milliseconds should be enough to catch it.  So, for 5 o' clock, you would make your range between 1250 and 1300.
Let me know if you have any questions.  Thanks!
