Import Media Files

Supported Formats

See Media Files for an overview of the supported media formats.

Aim

To select a video or audio file if you did not already do so when you created an observation.

Prerequisites

You carried out at least one observation. Your license for The Observer XT includes the Single Media Module or the Media Module.

Procedure

To Add a Video File

1. Open the observation.
2. Click the Import Video button on the Component toolbar.
3. Select a video file.
4. Optionally select Visualize Audio to display the audio of the video as waveforms. See Visualize Audio in Visualize Data.
5. Click OK.

To Add an Audio File

1. Open the observation.
2. Click the Import Audio button in the Component toolbar.
3. Select an audio file and click OK.

To Replace a Media File

1. Open the Independent Variable List window by doing one of the following:
   • Choose Setup > Independent Variables.
   • In the Project Explorer, click Independent Variables.
2. Click the ellipsis button next to the video you want to replace.
3. Select another media file and click Open.

To Remove a Media File from an Observation

To remove a single media file from an observation, open the Independent Variables list (see To Replace a Media File) and click the corresponding cell in the Video or Audio column. Then press Delete > OK.

The media file is only removed from your project, not deleted from disk.

Remove a Media File Variable

The instructions below remove a Video or Audio column in your Independent Variable List. This means that all the links between the video/audio files in that column and the observations are removed.

To remove a specific media file from your project, see To Remove a Media File from an Observation.

1. Open the Independent Variable List. See Independent Variables in Set Up Your Project.
2. Right-click in a Video or Audio column and select Delete independent variable.
3. Click OK.

Notes

• You can add one video and/or audio file to an existing observation in The Observer XT with the Single Media Module. With the Media Module you can add a maximum of 20 media files.
• Media files are always added with Scope Observation. See Variable Scope in Set Up Your Project.

Manage Analysis Results

Save Analysis Results

1. Make sure that the analysis result is open on the screen.
2. Click the Archive button on the toolbar.
3. Enter a name and click Save.

The analysis result now appears in the Project Explorer in the appropriate folder under Analyses.

Notes:

• The destination folder is named as the type of analysis you have run, and is located under Analysis Results in the current Project folder. You cannot save your analysis results outside that folder.
• The default name for the Analysis Results file is: <prefix><number>.arx. The prefix varies according to the type of result (Behavior Analysis, Reliability Analysis etc.). The number is augmented by 1 every time you save the result with the default name.

Open Analysis Results

Do one of the following:

• Choose Analyze, select the analysis type and then Open Archive. Select the result file and click Open.
• Click the Analysis result in the Project Explorer.
• Right-click the Analysis result in the Project Explorer and select Open.

Remove Analysis Results

To remove an archived analysis result, right-click it in the Project Explorer and select Remove. Removing an analysis result does not delete the file (*.arx) from the Analysis Results folder of your project. To open it again, click the Open Archive button on the Component toolbar.

Export Analysis Results

You can export analysis results to Excel or ASCII (text).

1. Make sure that the analysis result you want to export is open on the screen.
2. Choose Analyze > Export Analysis Results, or click the Export button on the Component toolbar.
3. Browse to the folder where you want to store the exported file. By default, this is the Export folder within your project folder.
4. From the Save as type list, select either Excel Workbook (*.xlsx) or Text File (*.txt).
   • If you choose Text File, select a column separator from the List separator list next to Encoding.
   • Optionally, select the option Merge header rows. Do so if you want to open the analysis results in SPSS.
   • Select whether you want to export as Unicode (UTF-16) — if your export file contains Chinese, Japanese, or Cyrillic characters, or characters like "ä", "õ" etc. — or ANSI, if you want to open the analysis results in SPSS.
5. Enter a name and click Export.

Notes:

• You can only export the current analysis result or those saved previously. If you plan to export many results, first save each of them, or export each of them before creating the next one.
• Exporting to text files: results in separate sheets are exported to separate text files. The name of such a file is: [File name]_[name of sheet].txt.
• Exporting to Excel: results in separate sheets are exported as separate worksheets within the Excel file.
