In order to restore the ability to record delayed videos, a new recording mode option is available in the global preferences under Capture > Recording. Note that this filtering is to remove the high frequency noise created by the digitization process, it should be left enabled unless you intend to run your own filtering algorithm on the data. It is now possible to completely bypass the data filtering by changing the global option under Preferences > Drawings > General > Enable coordinates filtering. Filling this timeline with discontinuous sequences will cause unexpected behavior. Each tracked point has an underlying timeline of positions that is not exposed to manipulation. If you need to track the same joint angle at distinct times in the video, create several angle tools and track them independently. In addition to the raw angle value, it is also possible to map the angular velocities or tangential velocities of two joint angles against each other. This is possibly the most practical way to use this feature, for example with the bike fit tool or a tool dedicated to the angles you want to review. The angle-angle diagram will also work for custom tools that contain angles. The diagram is defined during the overlapping period of time of the two angles considered. The overall shape of the cyclic curve can be compared to the literature or between athletes or sessions. A typical example is to plot the knee angle against the ankle angle over a few cycles of running or cycling. This is useful to get insights into the dynamics of a specific motion. These are diagrams that directly map the angular value of two angles against each other. Angle-angle diagramsĪ new analysis window for angle-angle diagrams has also been introduced at Tools > Angle-angle diagrams. The time options “relative” and “normalized” are also available. Trackable drawings that have an angle, including custom tools, will show up in the list of sources and can be checked/unchecked.
This window will let you visualize angular kinematics values like angular velocity or tangential velocity for angles that were tracked in the video. It is available under the menu Tools > Angular kinematics. Angular kinematicsĪ new kinematics analysis window has been introduced for angular kinematics. So if you track and angle drawing, its three points will show up in the linear kinematics window as three distinct trajectories that you can treat as any other trajectory. The trackable drawings (point, line, angle, custom drawings, etc.) have their individual points included in the trajectories. “Normalized” time will stretch trajectories to a common starting and ending point, to compare their “shape” over time.Įxporting trajectory data to CSV will export a common time column first and then one column per trajectory. “Relative” time will align all trajectories to a common starting point, to compare how they evolve over time. “Absolute” time will simply respect the original timeframe of the trajectory. When comparing several trajectories, three time models are available: absolute, relative and normalized. The name and color for the plot are taken from the objects configuration. You can check/uncheck trajectories to be included in the analysis. The linear kinematics window is now found under the menu Tools > Linear kinematics and supports multiple sources. The following screenshot shows the same angle object with different options applied. It supports three new options to switch between signed or unsigned angle, change direction from counter clockwise to clockwise, and switch display to the supplementary angle. The angle tool was improved to be more versatile.
The “data analysis” menu has been removed from individual trajectory drawings and placed in a global menu at Tools > Linear kinematics, as the window now combines data for all trajectories. See Angular kinematics and Linear Kinematics below.
#RAINBOW MOUSE CURSOR PACK SERIES#
It is now possible to export the time series of trackable drawings like the angle tool and custom tools. The global value for this fading is set under Preferences > Drawings > Opacity. Instead of having a needlessly complicated dialog on each drawing with a “persistence” value, all the drawings are now either always visible or follow a global option for fading in/out of their reference frame. The management of the opacity of drawings was simplified.
It is now possible to run multiple instances of Kinovea at the same time by changing the option under Preferences > General > Allow multiple instances of Kinovea.
This version introduces new kinematic analysis tools and focuses on polishing existing features and fixing bugs.
