Frequently Asked Questions (FAQ)

New in Version 3.0

How many users will the software license support?

Version 3.0 introduced multiple-user licensing to the Iris M™ Motion Amplification® software suite. Now, each user logged into an account on the PC will be able to run the Motion Amplification® software. This is true on both the Acquisition Device that was delivered with the system and the Analysis Only installation installed on a separate computer.


Keep in mind that by default, each user will store recordings in their own DocumentsRDIRecordings folder.

Can I capture, track and measure linear movement?

Yes!


Introduced in Version 3.0, "Transient Analysis" allows you to place ROIs in an image to track linear motion.


The new Transient ROI Icon:

 


Sitting at home during quarantine with a camera and only a 6mm lens, I happened to capture a video of a bird in flight. What amazes me is the limited information that the software needs to capture and track this object! Granted, not the best of recordings, but it pushes the limits of what the software can actually do. Yes, it's that spec in the upper right-hand window pane!

Can I add the Motion Map to older recordings?

You can absolutely add the Motion Map to recordings taken with older versions of Motion Amplification®!

How do I add the Motion Vector arrows to my ROIs?

First, there must be an ROI in the current recording. When one is present, the "Show Motion Vectors" icon will become available. You can click on this icon to add the display to your ROI(s):



The vectors have attributes which you can control by clicking on the drop-down arrow to the right of the icon. Generally, the vector display is controlled as a "group." You will see this menu:



Link to video showing how to add the Motion Vector arrows to your recording.

What is the Motion Map and how do I use it?

Introduced in Version 3.0, the Motion Map is a tool that uses color to draw attention to where motion is present. It is an overlay on the recording which you can control for both transparency and intensity.


This color overlay will be referred to as a “Motion Contour”. The motion contour indicates the amount of relative motion present at any given pixel. This is not a calibrated or absolute measure of motion, so ROIs should be used if accurate displacement values are desired. In multi-color mode, red indicates the most motion and blue indicates the least motion. In single color mode, pixels in red indicate the most motion.


The Motion Map is accessed by clicking on the following icon from the toolbar:



The video attached below gives a brief demonstration of the Motion Map.

Can I view Motion Amplification® Live?

Yes!


Introduced in Version 3.0, you can now amplify recordings live. In the RDI Technologies™ Acquisition software, click on the "Enable Motion Amplification®" toolbar icon. You will see the Motion Amplification® slider and Playback Speed slider appear. You are now amplifying the live feed from the camera!


This mode takes a lot of computing power and depending on your slider settings, you will actually begin to "go back in time." By clicking the "Return to Live" icon to the right of the Enable Motion Amplification® icon, you will return to the live feed.


Click the icon highlighted in the green box to begin Live Motion Amplification®:



You will know that you are in Live  mode by the appearance of the "Motion Amplification®" and "Playback Speed" sliders:

How can I hide or unhide an ROI?

New in Version 3.0 is the ability to hide the ROI boxes. This applies to all ROI types, Standard, Horizontal Shaft, Vertical Shaft and Transient.


To hide the ROI box:


  1. Draw an ROI
  2. Click on the ROI box to display the "ROI Properties" window
  3. Check the "Hidden" checkbox


To unhide the ROI box:


  1. Right click in the image area somewhere. It does not matter where and does not need to be where the ROI box "should" be.
  2. A new pop-up menu will appear. Click on the "Show hidden ROIs" item


See the video below for a quick demonstration.

New in Version 2.5

Can I make a measurement on a shaft or rotating component?

Version 2.5 is the first version of RDI Technologies™ software where rotating shafts can be measured. However, you must use one of the specific Shaft Measurement ROI's, Horizontal Shaft or Vertical Shaft. A standard XY ROI cannot make this measurement.


Related Articles:


Can a recording taken in a previous version of software be used to take a Shaft Measurement?

Can a recording taken in a previous version of software be used to make a Shaft Measurement?

Possibly.


If you have an old recording which has a good view of a shaft, you can open it in Version 2.5 or newer of Motion Explorer and add one of the Shaft Measurement ROI boxes (Horizontal Shaft or Vertical Shaft) to the shaft location. Keep in mind, the shaft must be large enough, have good lighting, and be either horizontal or vertical. If you only have a small portion of shaft in the background, it may not provide good measurements.

How can I reduce the size of an MP4 export? (Video Format and Quality)

Version 2.5 UPDATE


Use the "Export Specification" tool to change the quality and content of your MP4 exports.


New in Version 2.5 is a tool that you can use to determine the quality of the MP4 created during export. You have three choices: Low, Medium and High. High will produce the highest quality video and the largest file size. Low will result in the smallest file size and the lowest quality video. This selection determines the level of compression that is used when producing the video.


This tool also lets you determine the Video Format for the MP4. Available choices are:


Full HD (High Definition) 1920x1080

HD (High Definition) 1280x720

SD (Standard Definition) 640x480


The larger the format, the larger the size of the produced file.


The table below gives approximate file sizes for a 1 second video in each format at each quality.



Full HDHDSD
High277 KB144 KB30 KB
Medium277 KB144 KB30 KB
Low215 KB141 KB30 KB


The Export Specification tool looks like this (with the Video Format and Quality lines in the green box) and will appear after clicking on the "Export Video" icon  found to the right of the Playback Bar.

Can I see the phase difference between two ROIs in a recording?

Yes.


New in Version 2.5 is the ability to compare waveform peaks and find a relative phase difference between the waveforms.


To compare phase readings follow these steps:


1) Place two ROIs in the recording and let the software perform its calculations

2) (Optional) You can use the Spectrum to identify the peak frequency. If you know the frequency, this is not necessary.

3) Open the Time Waveform displays

4) Right-click in the plot that you would like to use as the Master for the reference

5) From the new pop-up menu, select "Set Phase Reference"

6) Enter the frequency at which you want to do the comparison

7) You will see the frequency appear at the bottom of the Master waveform

8) The other waveform displays will have a relative phase between their waveform and the master's


The video below gives a short demonstration comparing the relative phase between two ROIs in the X-axis

Can I amplify multiple recordings at the same time?

Yes you can.


Starting in Version 2.5, in Motion Explorer, you can select multiple recordings to amplify all at once.


On your tree-view list inside a collection, you will see the videos listed. Any video with a green check has been amplified. Any video with a yellow caution symbol needs to be amplified.


From within a collection, use the "SHIFT+Click" or "CTRL+Click" to select multiple recordings. After the necessary recordings are selected, click on the "Amplify Recording" icon from the ribbon bar. Note - the icon will also only appear active when a recording which needs to be amplified is selected.


The attached recording gives a short demonstration of this behavior.



I have a recording with some unusable data in it, is there a way to trim out the useful parts?

Yes!


New to Version 2.5 is the "Trim Recording" tool represented by this toolbar icon:



To use this tool:


  1. Begin by clicking on the Trim Recording Icon
  2. The Playback Bar will change its display. Now you will see a pair of red triangles below the bar
  3. You can click, hold and drag the sliders to the desired locations. You can trim the beginning or end or even a section out of the middle.
  4. When you have defined the section of the recording you want to snip and save, click the Trim Recording icon that is to the right of the Playback Bar
  5. The "Trim Recording" dialog box will appear
    1. You can give the new recording a different name
    2. You can open the recording after trimming
    3. You can choose to delete the original recording. By default, the original recording will be kept and a new recording will be created identified by "trim" in the name.
    4. Make your selections and click "OK" to complete the task

New In Version 2.3

How can I create more elaborate MP4s?

We realized that there was a need to create more elaborate MP4 video reports so, we introduced Motion Studio in Version 2.3. Now, you can add Title Pages, Annotations, Create Composite Collections of Videos, and do it all in a single MP4.


Please see the video at this link for a sample of some of the capabilities of Motion Studio.

New In Version 2.2

How do I calculate a Spectrum from only a portion of the Waveform?

There are two green triangle shaped sliders on the waveform. When you click and hold on the slider, you can move it through the waveform. Move these sliders from either end to limit the amount of the waveform that gets FFT applied. As you move the sliders and reduce the number of samples, you can see the reduction in the clarity of the spectrum.


See the attached video for a short demonstration.

New In Version 2.1

What is the difference between "Move" and "Import/Export" when using Motion Explorer?

When you use the "Move" function of Motion Explorer, all of your files are transferred from one storage drive to another. The original files are transferred to the destination and no longer reside in their original location. The description in Motion Explorer is updated with the drive letter and path of the new location.


When you use the "Export" function of Motion Explorer, all of your files are bundled into an "Export" file and an associated folder. You have the choice of deleting the raw data on the original computer or keeping both copies, the original and the exported version. If you choose to Keep the raw data, the Location shown in Motion Explorer will be the original path, not the exported path. If you choose to Delete the raw data, the entire file(s) will be deleted from the computer and inside of Motion Explorer. When you "Import" a previous export, the data will be placed back in the original Hierarchy as defined at the time of the Export.

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.


How can I reduce the size of an MP4 export? (Playback speed)

Adjust the playback speed


This method is available in Versions 2.0 and newer.


Some motion may be shown better by adjusting the playback speed. Slower motions, for example may become more obvious at a faster playback speed. Adjusting the playback speed will also change the size of the MP4 created from the recording.


  1. Open the recording you want to analyze and export
  2. In the bottom right-hand corner of the screen, slide the "Playback Slider" up and down to find the setting which shows the motion the best
  3. Faster playback speeds will produce smaller MP4 files. Slower playback speeds will produce larger MP4 files
  4. When the desired playback speed is found, click the "Export Video" button  found to the right of the Playback Bar


Adjust the Playback Speed slider as necessary until you achieve the size MP4 you desire.


Watch the attached video for an example.

NOTE - The attached video is working with a 1 second video in real time. Only the Playback Speed is altered.

Version 2.5 UPDATE:


The method for adjusting the Export Start and End positions was improved in Version 2.5. From that version on, you can simply click, hold and drag on the green triangles and move their positions.



Adjust the green triangles as necessary until you achieve the size MP4 you desire.


Watch the attached video for an example.

My recording flashes bright and dim during analysis when I move the Motion Amplification® slider. What could be wrong?

Behavior in Versions 2.3 and earlier:


When you record a video the "Lighting" selection will optimize the recording settings to reduce the flicker found in lighting supplied by Alternating Current (AC). This flicker will be at 50 or 60 Hz depending on your local electrical line frequency. Normally, the recording will be made at twice this line frequency. If the frame rate is set at a frequency other than twice the line frequency a beating (beat frequency) between the frame rate and lighting may occur. If you have selected "Other" as your Lighting selection then manually adjusted the frame rate so that it is no longer twice the line frequency, as you amplify the recording, the flickering will change the intensity of the lighting on the asset making it appear brighter and dimmer. To reduce this affect, you can either:


  1. Rerecord the video making sure to record at twice the electrical line frequency
  2. Filter your existing recording to eliminate the 50 or 60 Hz frequency

Version 2.4 UPDATE


To simplify the recording process, the Acquisition Mode and Lighting settings have been removed from the user interface. Now, all that is required is to slide the "Framerate (fps)" slider to the needed setting.

Can I export my data out of the Motion Amplification® software for additional analysis?

Yes. You can export the Time Waveform as a CSV (comma-separated values) file for additional analysis. Simply open the Time Waveform display from an ROI and right-click in the plot area. Select "Export" or "Export Waveform Data" from the new pop-up menu. The export will be stored in the same location with all of your recordings and videos. It will be in the "RDI" folder in a directory named "Export".


Versions 2.1 and earlier:                                                                                     Versions 2.2 and newer:

What is the Fmax used during a video recording?

Behavior in Version 2.3 and earlier:


In "Motion Amplification® " Acquisition Mode, when you have the "Camera Properties" Framerate field set to fps, Fmax will be half the entered frame rate. In "Displacement" mode, the "Framerate (fps)" field will change to read Fmax and it will display the actual Fmax value.


Version 2.4 UPDATE


To simplify the recording process, the Acquisition Mode and Lighting settings have been removed from the user interface. Now, Fmax will always be half the entered frame rate.


See the attached video to view this behavior.

How can I add displacement/velocity measurements in an MP4?

The annotation features inside the Motion Amplification® software allow you to embed text messages in the final exported MP4. You can use these features to document amplitude measurements.


Version 2.3 UPDATE


Use Motion Studio to add dynamic graphs and headings to your videos. Version 2.3 also allows you to embed Spectrum, Waveform, Spectrum & Waveform, and Orbits as annotation before the MP4 is created.


See the videos at these links for examples of the two different behaviors:


Version 2.3 and Newer.mp4

Version 2.2 and Earlier.mp4

How do I rename RDI Technologies™ Data Files in the Motion Amplification® software?

RDI data files can consist of many different files and folders. Each recording stores a folder and a file on your computer which have the same name. The two must continue to be linked by the same name. You can change the name of the recording, but ALL files associated with this recording MUST get renamed exactly the same. You could manually do this by finding the file and folder, then renaming each and every file in the folder with the same name, but this would be tedious and may lead to mistakes. The easier way is to use the RDI Motion Amplification® Software rename feature.


Follow these steps to rename a file:


  1. Open the video that you want to rename.
  2. Click on the "Information" icon in the upper right-hand corner -
  3. From the new Information window, click on the information icon to the left of the Recording Information
  4. You will be given an editable Recording Information window
  5. On the very top "Filename" line, to the right of the existing name, click on the "Rename Recording" icon -
  6. A new window will open. Enter the new name to the right of the "New name for recording" text and click [OK]
  7. Continue to click [OK] and close dialog boxes until you have returned to the Motion Amplification® window. In the upper left-hand corner, you should now see the new name for your recording as the "Source File."


Please watch the attached video as an example.

When I apply a filter, does it apply to the entire image?

Yes it does.


After the filter is applied, only objects moving at the same frequency will show motion. They may or may not be directly attached to the object of interest. In addition, as the attached report shows, you can filter different videos for the same frequency to find sympathetic vibrations in other locations.


This video report from Stuart Walker with Reliability Maintenance Solutions Ltd an Authorized Reseller of the Iris M™ System in the United Kingdom is an excellent example of how to use filters to determine root cause of a problem.

Version 2.1 UPDATE


Now, with the introduction of "Amplification Regions" you can specify that only a portion or portions of a recording be amplified. Then, by filtering you can specify that only the amplified regions get filtered.

Can I amplify only a portion of the exported MP4 video?

Yes. You can create a video which plays both amplified and non-amplified footage. To do this:


  1. Open the recording you want to analyze and export
  2. Find the section of the recording which best displays the motion you want to highlight
  3. Locate the Playback Bar, found just below the video window
  4. You will notice blue triangles at the far left and far right above the Playback Bar. These triangles indicate the portion of the video which will be amplified in the MP4. You can adjust the location of these triangles.
  5. With the cursor, move the Playback Position Indicator to the location where you want the amplification to begin
  6. Right-click on the Playback Position Indicator to reveal a pop-up window
  7. From the selections in this menu, select "Set Amplification Start." The blue triangle from the left will move behind the Playback Position Indicator's current location
  8. Use the cursor to move the Playback Position Indicator to the location where you want the amplification to end
  9. Right-click on the Playback Position Indicator to reveal a pop-up window
  10. From the selections in this menu, select "Set Amplification End." The blue triangle from the right will move behind the Playback Position Indicator's current location
  11. Right-click on the Playback Position Indicator to reveal a pop up window
  12. From the selections in this menu, select "Reamplify Recording" and allow the software to process the video
  13. The region between the two blue triangles will be the portion of the original video amplified in the MP4
  14. Click the "Export Video" button  found to the right of the Playback Bar
  15. Navigate to the "Videos" folder to find the exported video (default location - C:UsersUserDocumentsRDIVideos).


Version 2.5 UPDATE


The method for adjusting the Set Amplification Start and End positions was improved in Version 2.5. From that version on, you can simply click, hold and drag on the blue triangles and move their positions.


Link to Video of behavior in Versions 2.5 and Newer


Version 3.0 UPDATE


There is no longer a need to "Reamplify Recording" - Step 12 above. This will be done automatically when it is required. This option has been removed from the pop-up menu.



View the video below for an example.

How can I reduce the size of an MP4 export? (Export length)


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.
