. F_WireRemoval incorporates a tracker that tracks the region to be repaired through the image sequence.
To use the tracker, do the following:
| 1. | Drag the on-screen wire tool to position the repair region on top of the wire on one frame. This sets a user keyframe for the current frame, enabling tracking. |
| 2. | To start the tracker, press the Track Forwards button . |
If you haven’t set a user keyframe (step 1), the tracker cannot be started and F_WireRemoval displays the following message:
Please select a user key frame before tracking.
| 3. | When the track is ready, check that the wire has been correctly tracked across the other frames and adjust the track if necessary. The tracking controls in the tracker panel are outlined under Tracker Controls. Any points initially positioned off the image will remain off the image. This way, the tracker will not lose the wire at the edges of the image. |
| 4. | If after tracking the wire you adjust the position of the on-screen wire tool manually on one frame, you may want to create a smooth transition between the user keyframe you created and the track keyframes around it. The easiest way to do this is to go on the previous and next frame on the timeline and press the Delete track keyframe button  . This deletes the track keyframes around the frame you adjusted and forces NukeX to interpolate smoothly around the adjustment. |
Similarly, if there is too much jitter in the track between some frames, you can delete the track keyframes between these frames. This way, NukeX will interpolate smoothly from one frame to another.
If it is not possible to track the wire automatically, the wire can be manually keyframed. Adjusting the on-screen wire tool on each frame will automatically set user keyframes. Alternatively, they can be set by pressing the Create User Keyframe button 
in the tracker panel.
