How to remove the cross mark of the tracking camera drawn on paper in AE?

If you find that when tracking a camera in Adobe After Effects, the cross mark drawn on the paper will interfere with your tracking process, you can try the following methods to delete it:

Before tracking, remove the cross mark drawn on the paper from the scene.

If you have finished tracing, you can try to remove the cross mark by using the repair tool in After Effects. Select the frame marked with a cross and use the repair tool (such as cloning tool or repair tool) in After Effects to repair it. It takes some manual work and time, but it can help you delete cross marks.

If you have finished tracing and there is no original material, you can try to cover the crosshairs with the masking tool in After Effects. Create a new mask layer in the composition, and use the mask tool to create a mask around the reticle. Then put the mask layer on top of the tracked camera layer to cover the crosshairs.

Please note that these methods may take some time and manual work, depending on your situation and the number of cross marks that need to be deleted.
