Can I filter from the spectrum of an already drawn ROI?

Yes. Clicking the filter icon with an active ROI will pre-populate the spectrum window with the spectrum from that ROI.


See the attached video for an example.


How can I reduce the size of an MP4 export? (Original and Amplified Frames)

INCLUDE the original AND amplified frames


This method is available in Versions 2.0 and newer.


To reduce the size of the MP4, you can change the export content to include the original and amplified frames from the "Motion Amplification® Options" settings. You will find these settings by clicking the Gear Icon in the upper right-hand corner of the Motion Amplification® window.


  1. Open the Motion Amplification® program.
  2. Click on the Gear Icon in the upper right-hand corner of the window
  3. In the Motion Amplification® Options window, from the middle "Export content" drop down, select "Include original and amplified frames"
  4. Click "OK" to close the window and save the settings
  5. Create a new MP4

See the attached video for an example.

NOTE - The attached video works with a 1 second of real time recording at 100 fps playback speed.

If I export my data to a CSV file, what units will the values be in?

They will be in the units that were selected at the time of the export. The header of the CSV file will also show you the units label.


I'd like to use a filter but need to know how many the Motion Amplification software supports and what they do.

The Motion Amplification software can support all of the following filters as described in detail below. They can be applied individually or in combinations. In all of the examples below, the areas in green will be included in the video while the areas in red will be excluded. Because of their behavior, only one Bandpass, one Lowpass, and one Highpass filter can be applied to a video. You can use all three on the same video, but only one of each type. You can add as many Bandstop Filters as you need.


Bandpass Filtering


A bandpass filter will only allow frequency content between the low and the high cutoff to be amplified.  All other frequency content will be excluded from amplification. When you select "Bandpass" from the "Type" dropdown, you will be allowed to enter your "Low Cutoff" and "High Cutoff" values. You can either use the keyboard to type values into the fields directly, or use the cursor to drag the red circles on the spectrum display to the area of interest. In the example below, only motion related to frequencies between 16.6 Hz and 17.8 Hz will be amplified in the video.



Lowpass Filtering


A lowpass filter will only allow frequency content below the high cutoff to be amplified. All other frequency content will be excluded from amplification. When you select "Lowpass" from the "Type" dropdown, you will only be allowed to enter your "High Cutoff" value. You can either use the keyboard to type the value into the field directly, or use the cursor to drag the red circle on the spectrum display to the area of interest. In the example below, only motion below 3.8 Hz will be amplified in the video.
