Script to add 4 sets of data to markers
Hello to all, I’m trying to create markers in AfterEffects with 4-point tracking data embedded. I started out using the provided AE script called “Convert Selected Properties to Markers” to place markers on the timeline with the Position (x,y) values from a layer with CornerPin applied. The purpose is to eventually export the position data to a Flash movie with the markers coming up as Flash Cue Points.
When I select the CornerPin effect, and apply that script, however, only 3 sets of data are embedded into the markers. Also, the markers still need to be given a name, since Flash doesn’t see them (action script) unless they’re named (this is less of a problem, though).
Apparently this supplied script with AE is written only to support 3 sets of data. Does anyone have one written already, or could offer help in providing the java script necessary to make the markers contain 4 sets of data?
Thank you very much for any help!

I think they’re all there, it’s just that the UI for the marker only displays the first three. If you create a layer named test, apply Corner Pin to it, run the script, then apply this expression to a text layer you’ll see that the 4th parameter is there:
thisComp.layer(“test”).marker.key(1).parameters[“Corner Pin_Lower Left”]

Thanks so much Dan. Using your expression, I was able to confirm the 4 sets of data were in there. I made 4 text layers and changed the expression in each one to reflect the 4 separate marker-parameters. What’s really weird is how the UI messes it all up , even with the 3 sets that do show– It actually does something like Frame1: Param A, Param B, Param C; Then, Frame 2: Param D, Param A, Param B; and so on…
My next wait-and-see is to find out if the “real” data (numbers from your expression) actually translates to Flash cue points…
Anyhow, thanks again for your help!

Please let us know how it turns out.

Thanks very much Dan! It worked like a charm. The final result tracks in Flash almost as clean as the AE motion track.
Again, thank you for your generous time and support.

Hey guys,
I just came across this thread, and was wondering if you have had any experience applying tracked data from AE into dynamic text within Flash.
I understand how to convert cornerpin/tracked data into markers and cue points within the FLV, but it gets a little hazy when applying that data to dynamic text within flash.
There was a MAX conference that I found that went through the steps within AE/Mocha, but the code that was shown in the video throws several errors.
While I understand this is an After Effects specific thread, the possibilities of AE/Flash integration directly relates to finishing and deployment.
Any ideas?
Thank you!

Hi,
It works for me, but what about if I want to add 4 sets of data for multiple objects, when I export the data to Flash, I receive and error, and I believe variables are overwritten! there should be a way to rename the markers in After Effects!
Any insight is highly appreciated
