A new feature of Simcenter Testlab Neo Revision 2019.1 and higher is the ability to import a video and synchronize playback.  Video can be synced with vibration, sound, strain, or any other acquired data.

User-added image

After syncing the data, playback can include sound, data, and video!

This is explained in the following sections:

1. Getting Started and Importing Data
2. Manually Syncing
3. Interactive Syncing
4. Playing Back

1. Getting Started and Importing Data

Open a project file with Simcenter Testlab Neo Desktop.  This project should already contain some acquired time data (Figure 1).

Under File -> Add-ins, turn on “Video Replay” (12 tokens).  If synced replay with sound is desired, also turn on the audio replay add-ins.

Figure 2: Under File -> Add-ins, turn on Video replay.

The Video Replay add-in is needed to do interactive syncing (described later in this article) of the video file to the existing time throughput file. It is not required for importing the video file.

With the add-ins turned on, return to the Desktop.  Right click on the Run Name in the project tree.  Select “Import” (Figure 3).

Select a *.mp4 file (this is the only supported format) and press Open (Figure 4) button. Videos could come from different sources including GoPro Cameras, Simcenter Testlab Scope App, or Simcenter Sound Camera.

 The video is imported into the project and selected run.  Press the “OK” button to continue (Figure 5).

The project file (*.lms) will not grow in size after importing a video.  Large files like time data and videos are instead stored in a directory of the same name as the project.  Using windows explorer, the directory is the same folder as the *.lms file.  

While it appears as a single file in Simcenter Testlab Neo, in windows there is a separate folder for each data run which can contain a time file (*.ldsf) and video file (*.mp4).  This keeps the project file (*.lms) size smaller.

2.  Manually Syncing

To manually sync, right click on the video as shown in Figure 6. Choose “Video Time…”.  This works with absolute time (year, day, month, minute, second, etc) if it is available.

User-added image

Figure 6: Right click and choose “Video Time…”

Enter a new absolute time in the “Corrected Time Data” field. If the corrected absolute time (down to the nanosecond) is unknown to you, then use the interactive sync feature described in the next section.

3.  Interactive Syncing

To interactively sync the video and time data, hold down the control key and select both of the video and time data (Figure 7).

User-added image

Figure 7: Holding control to select both time and video will make them display side-by-side.

The time and video data will display side-by-side.  Right click on the video and choose “Add Video Sync” (Figure 8).

Cursors will appear in the displays (Figure 9):
•    Red Cursor – The red cursor is positioned in the time data.
•    Black Cursor – The black cursor is tied to the video.

User-added image

Figure 9: Right click on the video and choose “Add Video Sync”

Move the red and black cursors until the video and time data are at corresponding moments.

Note that arrow keys can be used to move the cursors one frame at a time.  It is also possible to zoom to a shorter time by clicking and dragging around the event of interest.

When finished, right click on the video and choose “Sync Video” (Figure 10).
