3D Text Tracking Test

Final shot screen-shot in After Effects
After spending several hours I was finally able to create my first 3D text track. The final video is here:


I shot some handheld footage in order to add some depth and dynamic movement as I felt the camera slider was limiting at times regarding x,y,and z planar information. I then took the footage into After Effects and began to work with the 3D tracker.

 I used the advanced method for the camera solve and spent some time finding the best points to use for the track. I then created a camera and text based of these points, tuning the text 90 on the x axis to bring it upright.

 After making sure the track was clean, I turned on the raytracing render mode in After Effects. This allowed me to extrude the text out and create some lights and shadow casting. I placed a shadow catcher and light beneath the text in order to generate more shadow and messed around with the settings to get a look and feel I felt was appropriate. Now, I experimented with the different textures i could apply to the text and finalized the comp.

Then, I sent the comp to media encoder and let the render fun begin...
