13: Multi-Angle Telestration

Overview

Paint has the ability to synchronize clips with footage of the same game from multiple angles and then share 3D graphics between them. All clips need to have pitch calibration defined.

Clip Group Editor

To synchronize multiple clips you first need to create a clip group. It contains information about the synchronization frames and the shared drawings.

Manage clip groups

To create a new clip group or edit and existing clip group:

1. Choose the Sync Clip option inside the clip context menu.
2. An editor will appear over the tools panel showing the content of the clip group with the chosen clip. There will be a row for each clip with its name and the sync frame visualized as a timer and a screenshot.

Synchronization frame

Clicking on the clips will select it for the purpose of editing the sync frame. To change it first seek to the desired frame and confirm by clicking the button in the preview. Both timer and screenshot will update.

Add angle

1. Click Add Angle.
2. All usable clips in the bank will start blinking.
3. Clip on one of them to add it or press ESC to cancel operation. Clips that are already in a different group cannot be added.

Remove angle

Each clip row has a bin button for removal from the group. Removing the last clip will result in group deletion and loss of its synchronized drawings.

Existing drawings

Clips added to the group can already have some drawings in them. Whether or not they will be converted to synchronized is set by the checkbox in the bottom right.

Exit editor

• Ok = Saves the current group state and close the editor.
• Cancel =  Reverts the group to previous state before editing and close the editor.
• Selecting another clip in the bank = Loads its group into the editor (if the selected clip is/can be synchronized just close the editor) if the selected clip cannot be synchronized.

If some changes were made in the current group a confirmation dialog will ask whether you want to save them.

Visualization

For clarity, both synchronized clips and drawings are marked with this camera icon.

Synchronized drawings

Synchronized drawings are inside the clip group and will be visible in its clips.

There are two ways to create synchronized drawings.

• Create a regular 3D drawing inside one of the synchronized clips and click save.
• Add a clip which contains some drawings as a new angle.

Switching angles

When inside a synchronized clip use "PreviousAngle" and "NextAngle" actions to cycle through the angles in one way or the other.

Current time and playback speed is maintained during the switch.

By default these actions are bound to:

• Win: CTRL + SHIFT + LEFT/RIGHT
• Mac: CMD + SHIFT + LEFT/RIGHT

Limitations

The accuracy of multi-angle telestration depends completely on 3D pitch calibration. Therefore, if one clip is recorded from a difficult angle and the automatic calibration doesn't produce accurate enough result, the drawings of other clips in such a clip will appear shifted and vice versa.

For such clips user can edit or define the calibration manually though the Calibration Editor.
