Help

1-Retime your sequence after this gizmo

ex. 100-360 ------- 0-260

 

2-Put the width format of your project

ex. 1080, 1556, etc

 

3-Clink on Create Keyframes this allowed to convert 3d information to 2d

(if dont work go to node tab click on copy to group open reconcile3D1 and press create keyframes)

 

4-Click on Bake your animation this bake your keyframe data frame by frame

(if dont work click on animation menu then right click--->Edit---->Generate-->ok)

 

5-Open the script editor and press TrackData

(make sure that you have selected tracker1)

 

6-Copy track data

 

7-go to AE create a adjusment layer open optical flares pulldown the options

effects--->optical flares and select Position XY and pasted (make sure that you pasted on the first frame)

 

[you can help using it and making it better]
