Drawing clone objects

Having found a key frame of video - one in which an athlete or object is in a position of interest, that athlete or object now must be cloned. You are not restricted to cloning a single object, so select all objects of interest in each key frame.

The objects or athletes that you want to clone are drawn, selected and manipulated using the tools on the right of the StroMotion module.

Select tool - select clones or move selection.
Rectangular clone tool - clone creation tool.
Freehand clone tool - freehand clone creation.
Delete selection - deletes the performer/object selected by the select tool.
Delete all - deletes all performers/objects on this frame.
Zoom in/out - zooms in on the point on the image that is clicked (right click to zoom out).


To create clones

Use the Rectangular clone tool or the Freehand clone tool tools to "draw" around the performer/object to be cloned.

To use the Rectangular clone tool

1.	Click the Rectangular clone tool button.

2.	Then point the mouse above and to the left of the object to be cloned.

3.	Click & drag downwards and to the right until the selection box encompass the object while including as little background as possible.

To use the Freehand clone tool

1.	Click the Freehand clone tool button

2.	Click & drag around the object staying as close to the edge as possible.

If you miss part of an object during selection, don't delete the clone and start again, simply include the missed part as a new selection. More than one tool can be used and more than one selection can be made to create a clone as shown in the image below.

Which selection tool is best?

To answer that, remember that whichever tool you use, the selected area will stay fixed on the video image. If there is overlap between clones, the later clones will obscure the earlier ones.

Use the freehand tool when there will be a lot of overlap between the clones. For example in a gymnastic rings routine or high jump.

Use the rectangle tool when the clones will be spread out - the performer moves some distance between the key frames. For example in long jump.

To edit clones

1.	Select the clone to edit by using the Select tool . Click the tool then click the outline of the cloned area.

2.	Selected clones can be deleted , moved by click & drag, or reshaped by dragging the "handles" at each edge or corner, see these illustrated below. All clones in a frame can be deleted using the tool, it is not necessary to select clones first to use this.

By zooming in on the image more careful selection is possible. Click the left mouse button to zoom in and the right mouse button to zoom out.
