Analysis tools help you highlight key points in the video and Pro8 has a lot of analysis tools to help you along.
This video gives you a demonstration of how they work. Press the Play button to start.
They key concept to remember is that almost all of the tools use the sequence of mouse down-drag-release.
One of the exceptions is the Measure angle tool which is mouse down-drag-release-move-mouse down-release.
Measuring time or angle do not need a calibration process but measuring distance does. This is because the software has no idea of the size of what it is showing in the video unless you tell it.
To calibrate, you first choose the calibrate button and then click on each end of an item you know the real world length of.
- To avoid perspective/depth errors your calibration object MUST be in the e same plane as you action. For example for running it must be on the track underneath where their feet will strike. You can’t have it on the wall behind them.
- To increase accuracy make the calibration object (e.g. 2 cones) as far apart as possible.
- The camera cannot move.
You also have colour, thickness, undo, and delete tools so make sure you take time to try them all.
