After Effects
After Effects file
The After Effects script file (.jsx) enables you to import video, camera, and null data into After Effects. In After Effects, nulls are used instead of the scan. These nulls don't exist by default
and must be manually created.
Export the .jsx file
- In the "Export Options", under "Third Party", ensure that AE (After Effects) is enabled.
- By default, a geometry doesn't contain any anchors (nulls), so you'll see "0 anchors". To add anchors, tap the “0 anchors” button.
- In the opened geometry view, tap on the geometry to place the nulls. To remove a null, tap on it again.
- Tap the "Back" button in the top left corner of the screen.
- Finally, tap "Export".
If you've selected multiple shots, use the "Next"/"Previous" buttons to navigate between the geometries. When you reach the last geometry and are satisfied with the anchor placements, tap "Completed".
Use the .jsx file in After Effects
- Open After Effects.
- In the top left menu go to File → Scripts → Run Script File... .
- Select the .jsx file you’ve exported.
After performing these steps, four items will be added to your After Effects project:
Comp_3D
: This composition includes the camera and nulls.Comp_3D+Plate
: This composition combines the "Comp_3D" with the video footage.The video
: This is the original footage associated with the shot.Solids
: This folder contains the nulls used in the “Comp_3D”.
The use of two compositions, "3D" and "3D+Plate", allows you to simulate the film offset variation that occurred during recording. Taking this into account can in some cases significantly increase the tracking quality.
When a specific type of surface is identified, the system automatically assigns a default name to any associated nulls. Applicable surface types include:
- Ceiling
- Door
- Floor
- Seat
- Table
- Wall
- Window
