Clipping mask
Posted in: Digital Fusion / DFX+Hi everybody!
At first I must say that I am a novice in Fusion(5.3). I passed through several tutorials and then I tried to make my first scene. As a background I have footage of video taken by the camera from helicopter. As a foreground I have footage of rendered model of circle crossroads. I used Merge node to connect it together. Next step was to eliminate sharp junction between 3d model and video. It was very expressive in one place. So I inserted Tracker node with 2 trackers, tracked all sequence. Next I draw a polygon mask with only one edge, set Border with and Soft edge and connect output to Tracker foreground. In Tracker I set Operation to MatchMove. At first frame everything looks o.k. but when I run to the end of the scene, camera moved to another position and mask was clipped.
I think that this same problem was discussed in this forum several times, but I wasn’t able to solve this. Pls If somebody can help me and explain it as for a stupid novice.:) Thanks!
