Drawing Illustration

While analyzing video, the app allows you to draw directly onto the video with your finger. A single finger is used to draw freehand, like using a pencil.

If you draw an approximate line or circle, your drawing will be converted into a perfect shape. If you draw an angle by drawing two separate lines, those lines will be combined into an angle shape with a degree measurement.

By default, you may use a two-finger touch to draw a line. This provides a very quick way to draw an angle--use a two-finger tap twice with your thumb at the vertex and your forefinger at each endpoint.

You may choose other two-finger shapes by touching the Draw icon in the upper-right corner of the analysis screen. Choose from Line, Circle, Box, or Pan/Zoom (a hand icon).

When Pan/Zoom is selected, you may use one or two fingers to move the image and to zoom-in on a particular region of the video.

To undo your most recent drawing, double-tap the image. To erase all drawing from the screen, gently shake the device.

To move existing objects, touch the Draw icon and then select the Arrow tool. Orange handles will appear at locations which may be touched and moved.

Illustrations on screen at the time you close the video analysis will be saved and automatically restored when you next analyze the video.
