Getting Started

I have drawn several ROIs on an image, which one will be used when clicking on the Filter icon?

The first ROI that was drawn will be the one that pre-populates the Filter Specification window.

How can I convert my frequency units between Hz and CPM?

You will find this selection behind the "Application Settings" gear in the upper right-hand corner of the Motion Amplification® software. Simply open the dialog window and make your selection. Because the amplitude units can depend on the frequency, the associated plots will not be redrawn until they are reactivated.

The attached video shows you how.

How can I change my amplitude units between Imperial and Metric?

You will find this selection behind the "Application Settings" gear in the upper right-hand corner of the Motion Amplification® software. Simply open the dialog window and make your selection. All of the associated plots will be changed when you save the new settings.

The attached video shows you how.

Can I change the amplitude units and modes on my Time Waveform and Spectrum displays?

Yes. While viewing either a Time Waveform or Spectrum display, right click in the plot area. From the new pop-up menu, select "Setup Options". The new window contains drop-down selections which allow you to individually select how you want your plots to display.

See the attached video for a demonstration.

How many ways are there to change the scale on a plot?

  1. You can use "Shift+click and drag" to zoom into a specific window or location
  2. You can use the +/- keys on your keyboard to zoom in around the center of the range, both X and Y.
  3. You can place the cursor where you want to center the zoom window and roll the mouse wheel.
  4. You can right click outside of the X or Y axis line and find a new Zoom/Pan and Autoscale menu.
  5. You can right-click and select "Setup Options" and from the top "General Plot Options" section, check the box for "Autoscale across plots of same type" to make both plots scale together.
  6. You can right-click and select "Reset Scale" to return to the default scaling
  7. Somewhat of a "trick" answer, but you can "minimize" windows you do not want to see by clicking the carrot (^) in the upper right-hand corner of the plot. This will essentially enlarge the plots you do want to see. While not technically changing the scale, it can make it easier to view the data you are most interested in.

What is the Aperture ring and how do I use it?

The aperture ring is a collar on the camera that can be rotated to increase or decrease the aperture. The effect is letting more or less light in, respectively. The convenient part about aperture settings is that the amount of light taken into the camera at a particular setting will be equal across different lenses. If you find a good setting for your configuration and decide you need to change lenses, you can use the same f-stop with the new lens.

How do I know which focal length lens to use?

In general, you should select the distance and lens combination that allows you to fill the full frame with the entire asset, including the base. It may also be beneficial to include some background objects such as piping or structures. Specifically, it will depend on several things:

  1. Size of the object you're recording
  2. Distance between the camera and the object

Below are examples using five different focal length lenses on the same camera all positioned 5.5 feet (1.7 m) from the object. As you can see, each lens halves the field of view or doubles the zoom.
