05b Linked keyframe animations – Chyron

Paths

Paths allow you to create one-click animations from an existing path:

Each existing Keyframe animation represents a path.
Clips imported from Virtual Placement 7 with Tracab are capable of carrying paths of all players.

Bind Tool to a path

Each path represents a position animation that can be used to animate another drawings. Several drawings can be bound to one path.

Select a clip that contains paths.
Select the tool you would like to bind to a path.
Press the Bind button.
Select one of the paths.

Only tools with motion tracking ON can be bound to Paths created by a motion tracked tool. Paths that cannot be used by the selected tool are not displayed.

Delete drawing bound to a path

Use Graphic eraser to delete drawings.

Change offset from the path

You can change the offset of the drawing from the path. The drawing will animate on the path but will keep a fixed offset from it.

Pick the drawing to be adjusted and place it on the desired offset from the path.

Edit existing path

The paths are editable. When a path is changed, the trajectory of all bound drawings is changed to follow the updated trajectory of the path.

Editing is implemented the same way as editing a Keyframe animation.

Choose which paths are visible

In default state paths are visible and accessible at the same time. But when pitch calibration is defined a user can come across two types of paths:

2D - Defined in pixel coordinates directly on the screen.
3D - Defined in meters on the virtual pitch set by calibration.

To see only one type or the other simple use the Paths view button in the left top menu to rotate between these 3 views:

All paths.

Only 2D.

Only 3D.

Shape paths

To adjust small imperfections in paths, coming from the Player Tracking processing
‎or after using the Join/Swap tools below, the path shaping tool can be used.

To shape a path, do the following:

Linked paths

If some paths are linked together for example with the Linked Cursor tool, all linked paths will act as one, meaning clicking on either one will select/deselect all of them, and will be visualized at the same time.

Smoothing

Path shaping tool also supports adjustable level of smoothing/propagation of the adjustments to the nearby times to control whether only the current position should be edited or a more realistic player movement is preferred (without spikes).

To adjust the smoothing level, hold the CTRL key (CMD on macOs) and scroll. The current level is visualized by a white highlight around the current keyframe. Examples:

Extending paths

Path shaping tool can also be used to extend paths on either end. To extend a path simply jog outside its definition (before beginning or after end). This is visualized as a dashed manipulator at last known position.

And then drag and drop the path manipulator to a desired position. This will define a new keyframe at given position and current time and add it to the path.

Swap paths

Another tool used most often to improve results of player tracker processing.

Allows to swap two paths crossing each other where at the crossing point, paths get swapped between players incorrectly.

To swap paths, use the following procedure:

‎Split paths

Any path can also be split into two at required time. Typical use case for this is cutting off sections which otherwise would be difficult to shape into desired form. The missing section then can be filled by extending the "well-behaving" part via the Shaping tool.

To split a path, use the following procedure:

‎Join paths

Typical scenario for Path Joining is connecting two distinct paths coming from the Player Tracking processing. Paths to be joined should not overlap in time. In case they are overlapping, the path that is starting first in time takes precedence.

To join two paths, do the following:

Remove path

Removing paths is not supported.

1.	Enable Path Shaping Tool by activating the Path Shape button. All existing paths get shown as circles for current player positions with a trail visualizing immediate previous and next movement.
2.	Click on any path manipulator to select it, visualize its whole trail and hide all other paths.
3.	Jog the time where the path needs to be shaped.
4.	Drag and drop the path manipulator to a new desired position.
5.	Click on the path manipulator to go back to edit other paths (step 1) or repeat steps 3 and 4.

1.	Enable Path Swap Tool by activating the Path Swap button. Existing paths get shown.
2.	Jog in time a few frames after the incident. Click one of the two path manipulators to select the path. Its selection is visualized with a blue color.
3.	At the same frame, click the other manipulator to select the second path.
4.	After both paths are selected, they are swapped at the point of the crossing, or at the point where they are closest to each other, when they are not crossing directly.

1.	Enable Path Split Tool by activating the Path Split button. Existing paths get shown.
2.	Jog to the time where you want the split to occur. Click the manipulator of the path that should be split.
3.	Path is now split into two and the first part (earlier in clip) stays selected and highlighted.
4.	Select the Shaping tool to edit/extend the first part or click the manipulator again to deselect the first part, jog forwards and select the second part.

1.	Enable Path Joining Tool by activating the Path Join button. Existing paths get shown.
2.	Jog to the 1st path time range. Click on the path manipulator to designate the first path for joining.
3.	Jog to the 2nd path time range. Click on the path manipulator to designate a second path for joining.
4.	Paths get joined.

No smoothing ‎only the current position is adjusted.
Low smoothing.
High smoothing.
