Abstract

One exemplary embodiment involves identifying a plane defined by a plurality of three-dimensional (3D) track points rendered on a two-dimensional (2D) display, wherein the 3D track points are rendered at a plurality of corresponding locations of a video frame. The embodiment also involves displaying a target marker at the plane defined by the 3D track points to allow for visualization of the plane, wherein the target marker is displayed at an angle that corresponds with an angle of the plane. Additionally, the embodiment involves inserting a 3D object at a location in the plane defined by the 3D track points to be embedded into the video frame. The location of the 3D object is based at least in part on the target marker.

Claims

1. A computer-implemented method comprising:

identifying a plane defined by a plurality of three-dimensional (3D) track points rendered on a two-dimensional (2D) display, wherein the 3D track points are rendered at a plurality of corresponding locations of a video frame;

displaying a target marker on the plane defined by the 3D track points to allow for visualization of the plane, wherein the target marker is displayed at an angle that corresponds with an angle of the plane; and

inserting a 3D object at a location in the plane defined by the 3D track points to be embedded into the video frame, the location of the 3D object based at least in part on the target marker.

2. The computer-implemented method of claim 1, further comprising moving or resizing the target marker in response to a received input.

3. The computer-implemented method of claim 1, wherein at least three 3D track points define the plane.

4. The computer-implemented method of claim 1, wherein identifying the plane defined by the 3D track points comprises:

receiving a selection of 3D track points; and

identifying the plane defined by the selected 3D track points.

5. The computer-implemented method of claim 1, wherein identifying the plane defined by the 3D track points comprises:

determining at least three 3D track points closest to a cursor rendered on the display that define a plane encompassing the cursor; and

identifying the plane defined by the at least three 3D track points closest to the cursor.

6. The computer-implemented method of claim 1, wherein the target marker is configured to be moved along the plane defined by the 3D track points.

7. The computer-implemented method of claim 6, wherein the target market is configured to be moved along an x-axis of the video frame, a y-axis of the video frame, and a z-axis of the video frame.

8. The computer-implemented method of claim 1, wherein the 3D object comprises at least one of a text layer, a solid layer, a null layer, or a shadow catcher layer.

9. The computer-implemented method of claim 7, wherein the solid layer is configured to receive an image.

10. The computer-implemented method of claim 8, wherein the null layer is invisible and is configured to receive an image.

11. The computer-implemented method of claim 7, wherein the shadow catcher layer is configured to catch a shadow of a previously inserted 3D object and wherein the shadow is cast by a light associated with the shadow catcher layer.

12. The computer-implemented method of claim 11, wherein the target marker comprises a plurality of concentric circles.

13. A system comprising:

a processor for executing instructions stored in computer-readable medium on one or more devices providing an application for specifying modifications to electronic content,

the application comprising one or more modules configured to perform the steps comprising;

rendering a plurality of three-dimensional (3D) track points on a two-dimensional (2D) display, the 3D track points corresponding to a plurality of 2D source points of a video composition;

rendering a 3D target marker on the 2D display of a plane defined by at least three 3D track points; and

inserting a 3D object in the 3D target marker to embed the 3D object into the video composition.

14. The system of claim 13, wherein the target market is configured to be moved within the defined plane of each frame of the video composition,

15. The system of claim 13, wherein the at least three 3D track points is determined by identifying at least three 3D track points appearing closest to a mouse that define a plane encompassing the mouse.

16. The system of claim 13, wherein the at least three 3D track points is selected by a user.

17. The system of claim 13, wherein the 3D object comprises at least one of a solid layer, a null layer, a text layer, or a shadow catcher layer.

18. The system of claim 17, wherein the shadow catcher layer depicts a shadow of a previously inserted 3D object cast by a light associated with the shadow catcher layer.

19. A non-transitory computer-readable medium on which is encoded program code, the program code comprising:

program code for identifying a plane defined by at least three three-dimensional (3D) track points rendered on a two-dimensional (2D) display, wherein each of the 3D track points correspond to a 2D source point of a video composition;

program code for rendering a target marker defined by the plane, wherein the 3D target marker comprises a plurality of concentric circles; and

program code for inserting a 3D object in the plane marked by the target marker to be embedded into the video composition.

20. The non-transitory computer readable medium of claim 19, wherein the 3D object comprises at least one of a text layer, a solid layer, a null layer, or a shadow catcher layer.
