Licensing Errors

There are several instances where you may be asked to enter your software license after the system has been running.


First, make sure that the Acquisition System or Analysis Only computer is connected to the Internet.


  • Incorrect Date and/or Time on the Acquisition Device


In some cases, the time on the computer will get out of sync. You may see a message about "The system time is not valid."



The first thing you should check is that the date and time on your computer matches the current date and time. Assuming the computer is behind, adjust the date and time. Do this by right-clicking on the date and time in the system tray and select "Adjust date/time" from the pop-up menu.



Depending on your current settings, you may have to disable the "Set time automatically" button to manually adjust the time. Sometimes, simply changing the "Set time automatically" toggle will actually correct the time.



Close and save the time then try to re-open the RDI Technologies™ Software.


  • License Status Update or General Connection Error


If you are presented with the licensing screen and the License ID is already filled in, check the center bubble for "Refresh my license" and then click "Next." This should reactivate your software.



  • Loss of Credentials Completely


If you are presented with the licensing screen and the License ID is NOT filled in, please try re-entering the License ID and password that was provided with your system. Please see the article, "Where can I find the details of my software licenses?" for how to find your original credentials.



  • Missing License Path


In some cases, the software will display the message "The license could not be saved. Access to the path 'C:ProgramDataRDIRDISystemLicense.lfx' is denied."


There are two solutions available for this:


1) Update to Version 3.0.2.0 or newer by clicking on the "How do I update my Iris M™ software?" link 

2) Create the RDI folder by:

  1. Open a Windows "File Manager" window and navigate to "C:ProgramData". - NOTE this is a Hidden Folder and you will have to select "Show hidden folders" from the "View" Ribbon Menu
  2. You should NOT see an RDI folder in this location
  3. Right-click and select "New folder"
  4. After the folder is created, rename it to "RDI"
  5. Close all open windows
  6. Try opening the RDI software again

I get an error from the Acquisition or Motion Amplification® software that the "License is Expired." Is there anything I can do?

This will normally happen after you try to update from one version to another. In that case, if you do not have a current Software Support Agreement with RDI Technologies™, the software will prevent you from running the newer version. The only way to resolve this issue is by uninstalling the newer version of software and reinstalling the original version.


To prevent this, you can check the expiration date of your Software Support Agreement BEFORE you update any software.


The expiration date will be shown on the "Information" screen shown below. To open it, click the "i" inside the blue circle in the upper right-hand corner of any one of the RDI Software applications, highlighted by the green box below. The expiration date will be at the very bottom under "Manage License" as shown in the bottom green box.

My RDI Technologies™ Software is misbehaving, is there anything I can do?

Sometimes, a setting in the software's configuration files will get stuck, mismatched, or just confused! When this happens, you may see strange behavior in the RDI Suite of programs. One potential solution is to delete the configuration files by following the steps below:


1) Open a File Explorer window




2) Navigate to the "C:" drive by clicking on "This PC" and then "Local Disk (C:)" (Note - your names may not match exactly, but you are looking for the root of the C: drive.



3) In the Search Window in the upper right-hand corner of the screen, type "rdi*cfg" and press enter. (Note - the * symbol is created by pressing SHIFT+8)



4) Wait for the results. It may take as long as 30 seconds, but you should find something similar to what's shown below.



5) Select all of the files and delete them. Depending on the version of Windows you are running, they may go grey or you may not notice any real change at all.



6) Type "rdi*cfg" in the search window again and press ENTER.



7) This time, you should see the "No items match your search" message.



8) Open any of the RDI programs normally. You may be prompted to set your Line Frequency or even measurement type and units again. This is normal and should only appear once.


If this does not correct your problems, please contact RDI Support by using the contact info on the support web page.

Why does playback in the Motion Amplification® Software seem slow?

Some of the features that may be running in the background can require computer processing resources. Things like the Orbits and Waveform displays get redrawn in real-time as the video plays. If these background tasks are complex, they can slow down the video playback. Make sure that any background windows are closed if they are not essential to the work you are currently doing.


NOTE - You will lose any ROIs which are currently active if you close the Spectrum Window, but since it is not redrawn during playback, we recommended that you leave the Spectrum Window open.


Version 2.3 UPDATE


You no longer lose the ROI's location when closing all of the measurement windows.

I have installed the Motion Amplification®program on a separate computer, but now I need to remove it and install it on another computer. How do I do this?

Please contact RDI Technologies™ directly. If you can provide the "License ID" of your installation, it will help speed up the process. The location of the License ID is shown in the attachment. Our license server needs to be updated to allow the new computer. You will be issued a "Deactivation" for the existing computer and instructions on how to use it. Then, you can reactivate your Motion Amplification® program on another computer.

Can I record video on another camera and use it for Motion Amplification®?

No you cannot. The system is highly optimized for the camera and lenses originally supplied with the Iris M™ system.

How do I rename files in the Motion Explorer Software?

Renaming Folders, Assets, Collections or Recordings in Motion Explorer is very similar to renaming objects in Windows Explorer. You can either right-click on the item and select "Rename" from the pop-up menu or select the desired item and use the "Rename" ribbon icon from the top of the screen. This icon looks like this in both locations .


See the attached video for examples.

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

When I begin to record, the Recording Bar below the image begins to turn yellow. Why is this?

The yellow portion of the image is that part of the recording which is still stored in memory and has not been written to the Solid State Disc Drive (SSD) of the Acquisition Device. The entire system, hardware and software, have been optimized to reduce this. However, as the SSD gets full, it becomes harder for the Acquisition Device to efficiently store your recording. Also, if several software programs are running in the background while you are recording video, the computer must multitask between these programs. Each of these slows the performance of your Acquisition Device.


To improve the performance of your computer you can:


  1. Keep your Hard Disc as clean as possible. You may want to have a separate storage Disc Drive for archiving your files.
  2. Close any background programs that are not necessary for recording video

Why do some questions have multiple answers?

As we get feedback from our customers, our Development Team implements new or improved features to improve your experience with Motion Amplification®. In these cases, the behavior may be slightly different between versions. In most cases, the original behavior is retained with the newer improved behaviors added. This means less change for existing users while offering improvements to everyone. In cases like this, to show both the new and original behavior, many of the early articles have been updated with a "Version X.X UPDATE" section. 


In some cases, multiple answers are available to solve the same question.

How do I get on the Refresher Course notification list?

Please email your request to support@rdi-technologies.com and we will add you to the database. When refresher courses are available, you will be notified of the subject, location and date for all upcoming classes.

What can I do if my Iris M™ Acquisition software doesn't recognize the camera?

If the software doesn't recognize the camera or if it recognizes the camera as a USB 2.0 then you can try this.


You may want to try the following steps if you are hearing “plin-plon” of USB connection/disconnection from the Surface Book.


One thing you can check is the connection between the two halves of the computer. There is a "Detach Tablet" button in the upper right-hand corner of the keyboard. It is the button just to the left of the "Del" key. Press and hold it until you hear a click. Then, pull up on the screen portion and it will disconnect from the keyboard.

Clean the connectors between the two halves with some alcohol and compressed air. This is a magnetic connection and all of the USB ports run through it. So, we have seen it pick up some debris during use.


If nothing changes you can shut down the software and restart the computer and after it restarts open the software and try again.

Where can I find the details of my software licenses?

Your Iris M™ Acquisition System is delivered with a USB Memory Stick with an RDI Technologies™ logo. On that stick you will find the licenses issued with your system. The same files have been copied to the "Downloads" folder on the Acquisition System. They will typically be identified by your company name and may also include a contact name from your company. The file will be in a Text format. See the "Typical Files on USB Stick" figure below.


Typical Files on USB Stick:


After you open the text file, you will see that there are two licenses delivered with your Iris M Acquisition System. ("Typical License File" figure below.) The first, which is preinstalled in the system before delivery, is the "Full" or "Acquisition System" license which will activate the RDI Acquisition, Motion Amplification®, Motion Studio and Motion Explorer software. (For the difference between these see this article: RDI Technologies™ Acquisition Software vs. RDI Motion Amplification® Software vs. RDI Motion Explorer Software vs. RDI Motion Studio Software vs. Motion Monitor Software) This license is already active when you receive your system. You should see the four different icons associated with the RDI Acquisition, Motion Amplification®, Motion Studio and Motion Explorer software on your desktop when you first boot up the system.


Typical License File:



The second license will be identified as "SA" or Stand Alone or "Analysis Only". These three labels are all the same. This license is used to activate the Motion Amplification®, Motion Studio, and Motion Explorer software on a second analysis computer. When prompted, enter the license information into the license screen and select "Activate a license or renewal" as shown in the figure below.

I need to record a higher Fmax or Frames per Second than the Acquisition Software will currently allow. How do I increase Fmax?

In order to increase Fmax, you must 'crop" the collected image. The best way is to decrease the vertical resolution (Height) of the image which allows you to increase the acquisition rate. Decreasing the Width of the recording will also allow you to increase Fmax, but at a slower rate.


See the video below for exactly how to do this and just what it means.

What is the difference between a Region of Interest (ROI) and Zooming the View?

What are some ways I can add multiple ROI's to a recording?

This behavior has changed several times since it was first introduced. In some cases, the original behavior was retained, in some cases, it has been improved and updated. Please see the instructions below for the specific versions.

 

 

Appearance and behavior in Version 2.0


In Version 2.0, the ROI icon will appear as shown above. To add multiple ROI's in your video you have to left-click, hold and drag the first box. It will be RED in color. To draw the second box, you had to press the Control [CTRL] key then left-click, hold and drag additional boxes. New boxes will be BLUE, GREEN, ORANGE, YELLOW, PINK, then RED with this sequence repeating. Between each ROI, you have to wait for the measurement calculations to complete before starting to position the next ROI.

 

 

Appearance and behavior in Version 2.1


In Version 2.1, the ROI Icons were changed to those shown above. In this version, a "Persist" mode was added.

When the Motion Amplification® software is set to "Standard Mode", your icon will look like this: . In this mode, you add multiple ROIs by following the same procedure as described above for Version 2.0.

When you click on the down arrow between the two icons, your icon will change to this: . To draw ROIs in this mode, you only need to left-click, hold and d

rag with your mouse. Every time you release, an ROI will appear. When you click another location, you will begin drawing a new ROI. Between each ROI, you have to wait for the measurement calculations to complete before starting to position the next ROI.

To switch between the two, simply click on the arrow to the right of the ROI icon, . Choose the mode you would like to activate and click on the name to close the menu:

 

 

Appearance and behavior in Version 2.2

 

In Version 2.2, Standard Mode was changed to "Independent Mode" as shown above. The behavior is still as described in Version 2.0 above, only the name was changed. "Persist Mode" behaves as described in the Version 2.1 section above.

 

 

Appearance and behavior in Version 2.3 and Version 2.4

 

In Version 2.3, the ROI Icon has returned to the original design. However, the behavior is as described under "Persist Mode" in Version 2.1 above. Simply left-click, hold and drag to add ROIs to the video. You can still hold the CTRL, left-click and hold to draw multiple ROIs as well.


You can now click the "Cancel" button as the first measurements are calculated. Early measurements will be suspended until all of the ROIs are placed. Allow the measurements to calculate after placing your LAST ROI and all previously placed ROIs will have their measurements calculated at once saving you time.

 

For example, if you want to place four ROIs in your video, you can left-click, hold and drag to place the first ROI. As the measurement dialog appears, click "Cancel" and place the second and third ROIs in this same manner. When you place the fourth ROI, allow the measurements to calculate and all four will be presented when done.

 

Appearance and behavior in Version 2.5

 

 In Version 2.5, the order of the two ROI icons is reversed. Delete is on the left and the Type of ROI selection is on the right. In this mode, you place ROIs by left-clicking, hold and drag in the area where you want to ROI. You can place multiple ROIs by continuing this process everywhere you want an ROI. You can suspend the measurement calculations and complete them with the last ROI placed.

 

In this version, you have two new ROI types, the “Horizontal Shaft” and the “Vertical Shaft” measurement tools. As the icons indicate, you will be able to measure shaft movement on a shaft which is recorded horizontally using the Horizontal Shaft tool. Shafts recorded in a vertical orientation are measured using the Vertical Shaft tool.

 

Appearance and behavior in Version 3.0

 

 The ROI Icons appearance is unchanged in Version 3.0, but there is a new “Transient” ROI tool.


 

This type of ROI will track translational movement and show you the path of such motion.


PURPLE was introduced as a 7th color in the sequence in this version. Now the color cycle, RED, BLUE, GREEN, ORANGE, YELLOW, PINK, PURPLE, RED, will repeat.

How do I get a higher frequency resolution in a recording?

The only way to raise the frequency resolution is to increase the time of the recording. Frequency resolution can be expressed as 1/t where t = recording time. For example, a recording time of 1 second will allow you to resolve to 1Hz, at 10 seconds you can resolve to 0.1 Hz, at 20 seconds you can resolve to 0.05 Hz.

My camera (hardware) isn't recognized or I get strange behavior in the software the first time the program runs. What could be wrong?

There are several prerequisite software packages installed with the Iris M™ software. Some configure the camera, some the video display. In some cases, your virus protection software may identify these prerequisites as potentially harmful and block their installation. You may have actually seen various pop-up warning messages during the initial installation. In order to make sure that the program gets installed as intended, we recommend that you disable all virus protection software during the software installation process. You can re-enable it after the installation has completed and the Iris M software will function normally.


Sometimes, if you install from the internet, or from within the ZIP file you downloaded, you may have troubles. You may also want to try reinstalling the software.

Check things in this order:


  1. Make sure that the lens cover is removed (OK we'll give you this one, but we had to mention it!)
  2. Adjust the aperture setting to its lowest value (widest opening to allow the most light) for the current ambient light conditions as discussed in the article What is the Aperture ring and how do I use it?
  3. Begin sliding the "Brightness" slider all the way to the right, toward 100% as describe in the article What is the Brightness slider for and how do I use it?
  4. Slowly add gain as described in the article What is the Gain slider for and how do I use it?

What are some of the challenges when recording indoors?

Behavior in Version 2.3 and earlier:


Lighting is the biggest challenge when recording inside. Because indoor lighting is typically powered by Alternating Current (AC) the fluctuations in light intensity can be seen when using Motion Amplification®. One of the symptoms is found in the article: My recording flashes bright and dim during analysis when I move the Motion Amplification® slider. The Iris M™ System contains helpful tools to automate selecting compatible recording rates. Using the selections from the "Acquisition Mode," "Lighting," "Framerate (fps)" and "Fmax (Hz)" boxes under the "Camera Properties" section of the RDI Technologies™ Acquisition software will configure your recording for compatible frame rates giving you the best quality videos at all Motion Amplification® settings.


Be aware, we have even seen flash rates at frequencies "around" line frequency. So, your filters may have to be adjusted slightly to eliminate the actual 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.


See the attached videos for locating and using these controls.

What is the Gain slider for and how do I use it?

The Gain slider adjusts the sensitivity of the camera’s sensor. Use it sparingly. By increasing the gain, you will brighten your image, but you will introduce more noise and decrease the quality of the measurement. Sometimes this is necessary when the image is too dark. This value is scaled from 0 to 30.0. Always set the Brightness slider first, then add the least gain necessary. You may also want to add supplemental lighting to reduce the need for excess gain. There are three ways to move the slider:


  1. You can place the cursor over the slider and left-click and hold it. While holding, move the cursor left or right to adjust as necessary.
  2. You can left-click on the slider then use the Left/Right arrow keys to step the values up or down.
  3. You can click inside the box and manually type numbers into the field. NOTE - the value will not change until you exit the field. You can either press the TAB key or click in another box.


In the attached video the three adjustment methods are displayed. You can also see the effect that moving the slider has on the image.


Version 2.5 UPDATE


The Gain slider plays an important part in Shaft Inspection recordings. Here, you want to set the Gain slider as HIGH as possible and the Brightness slider as LOW as possible. This allows for the shortest exposure time and clearest picture of a rotating shaft.

What is the difference between a Region of Interest (ROI) and Zooming the View?

When using RDI Technologies™ Acquisition Software, if you left-click and drag the cursor on the screen, you will draw a red box. This box becomes the "Region of Interest". The image will be cropped to include ONLY the video inside of this box. All surrounding images are ignored. You can use this to reduce the amount of data recorded and stored by the camera. This becomes useful as you try to record at higher Frames per Second or Fmax values.


Using the ZOOM icons simply allows the user to focus on a smaller portion of the video being recorded. This is useful for improving the focus of the image. The difference in this case, is that the image surrounding the current view is still recorded.


See below for examples (assume the asset in these pictures is always the same size):



The ZOOM icons in the RDI Acquisition or Motion Amplification® software:

How long of a recording can I collect?

There is no specific maximum length of recording. It will depend on the available free Hard Disc space on the Acquisition Device. Keep in mind that processing time increases at a faster rate than recording time.

How do I extract Files from a Compressed (Zipped) Folder?

In order to save and replay Raw Video files from another location, all of the original files must be transferred and stored in the same location. There will be a file folder and individual file which both have the same name. The individual file will end in ".RDI" and is recognized by the Motion Amplification® software as a known file type. Clicking it will launch the Motion Amplification® software and load the video.


To extract files from a Compressed (Zipped) Folder follow these steps:


  1. Save the ZIP file to the "Recordings" directory on your computer. The default location will be "C:UsersUserDocumentsRDIRecordings" where "User" will be replaced by the name of the User who is logged into the computer
  2. Right-click on the ZIP file and select "Extract All..." from the pop-up menu items
  3. From the "Select a Destination and Extract Files" window, select the "Recordings" folder. Most likely, you will just have to delete the file name from the end of the path shown in the window.
  4. Click "Extract"
  5. When the process is complete, you can click on the file name which has the .RDI ending and the Motion Amplification®  Software will open.


Please see the attached video for a demonstration of the extraction process.

What is the Brightness slider for and how do I use it?

The Brightness slider adjusts the brightness of the image by changing the exposure time of the image. The larger the brightness level the longer the exposure time. This value is scaled from 0 to 100 percent. There are three ways to move the slider:


  1. You can place the cursor over the slider and left-click and hold it. While holding, move the cursor left or right to adjust as necessary.
  2. You can left-click on the slider then use the Left/Right arrow keys to step the values up or down.
  3. You can click inside the box and manually type numbers into the field. NOTE - the value will not change until you exit the field. You can either press the TAB key or click in another box.


In the attached video the three adjustment methods are displayed. You can also see the effect that moving the slider has on the image.


Version 2.5 UPDATE


The Brightness slider plays an important part in Shaft Inspection recordings. Here, you want to set the Brightness slider as LOW as possible and the Gain slider as HIGH as possible. This allows for the shortest exposure time and clearest picture of a rotating shaft.

When configuring my recording, how important is the accuracy of the measurements for Distance and Focal Length?

Accurate entries for Distance to target and Focal Length are REQUIRED for accurate displacement measurements. Displacement calculations depend on these entries with an error equivalent to the error in the measurements. The closer you are to an object, the more critical the accuracy of the entries becomes because the error has a larger impact. For example, a 1 inch (25 mm) error at 12 inches (305 mm) is a larger percentage than a 1 inch (25 mm) error at 100 inches (2540 mm).

What are some of the challenges when recording outdoors?

One of the biggest challenges when recording outdoors is lighting. Outside, you have access to a huge DC light source, the sun, so you would think you would have ample light. But, the sun may not always be where you want it or unblocked. On days when the sky has a scattered cloud layer, you may find yourself drifting in and out of good lighting. We had one instance where for the final shot of the day, a cloud suddenly appeared and made the shot unusable. The only solution in this case was to rerecord the video!


Even when you are outside, you may find that you need to add external lighting. Typically, overcast or mostly cloudy days will provide the most consistent even lighting. 


Version 2.5 UPDATE


Saturation Tool IconThe "Saturation Tool" (icon above as found in the Acquisition software) may also give you some insights on how much the lighting is changing in a particular scene. As the lighting changes, the saturation tool will change in real time showing you changes in the lighting patterns.


See the attached video for a sample of what you may see using the saturation tool.

Using the RDI Technologies™ Acquisition and Motion Amplification® Software on the Microsoft Surface Book as a Tablet

For Video Acquisition - Because you need the USB ports, using the Surface Book as a tablet takes a little creativity. But, if you detach the tablet from the keyboard, turn it around, reattach it, and close it up - this is a little awkward because of the extra protective case - you can use the stylus and onscreen keyboard to acquire data.


For Motion Amplification® - You can detach the tablet and use the Motion Amplification® software. Here again, use the stylus and onscreen keyboard as necessary.


Microsoft Surface Book 2 Update (released about Nov 2017)


The stylus is no longer standard with the Surface Book 2 according to Microsoft.

What are some advantages to creating "paper" reports?

By using Microsoft Word or similar programs, you can cut and paste the Time Waveform and/or Spectrum Plots for viewing. You can also place your large video files on a server and insert hyperlinks into your document to keep from having to email large video files.


Version 2.1 UPDATE


In this version, there are two new menu items in the Waveform Plots window which easily allow you to save the plot as an image.


  1. Right-click on the data in the plot to display a pop-up menu. Select "Copy" to copy the waveform data where the cursor was when you clicked. You can then paste this waveform directly into a document.

    NOTE - when using this method, the location of the cursor will be the last one shown on-screen when you clicked. This can be useful for adding Time, Frequency, or Amplitude information from the plot.

    An example of the Waveform and Spectrum window pop-up menu:

    A sample of the image copied using the above method:
  2. Right-click on the data in the plot to display a pop-up menu. Select "Save Image" to save the plot to an image file.

    An example of the "Save Image" pop-up menu:

    The selections available in Version 2.3 and earlier:


    The selections available in Version 2.4 and newer:



    Then, you will have the opportunity to rename the Image file:


    The Image file will be saved in the "C:UsersLucasPC-1DocumentsOther Files" folder. (LucasPC-1 will be replaced by the user's account name, typically Iris M on the Acquisition Device.)

Version 2.3 Update


Now, the majority of your reporting needs can be filled by using Motion Studio. Motion Studio brings paper reports to life by including everything in a single video. You can still use these techniques, but instead of adding it to a paper report, you will be using the images in a video presentation.

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.
