Here’s a quick Content-aware Fill step-by-step:

1. Start a new After Effects project.
2. Import the video clip.
3. Save the project with a descriptive name.
4. In the Project panel, right-click the Clip and choose New Como from Selection.
5. In the resulting Composition, Layer 1 will already be selected.  Select the Rectangle Tool and then click and drag around the white text.  Draw the Mask so that there is a little space around the white text (the space should be about 1/5 the hight of the white text).
6. While the Layer is still selected, press M to show the Mask Path and change the Math Path pop-up menu from Add to Subtract.
7. In the Content-aware Fill panel, Fill Method pop-up menu to Edge Blend and then click “Generate Fill Layer”.
8. As soon as it finishes, save the project again.
9. While the Composition panel or the Timeline panel is selected, choose Composition > Add to Render Queue.
10. In the Render Queue, set the Output Model pop-up menu to “Best Settings” (this is the default) and the Render Settings pop-up menu to “High Quality”.
11. Save the project again and then click Render.
12. When the render is complete, save the project and close After Effects.
