To Open Locations with the Carousel Control

Do one of the following:

• Press the carousel control buttons to browse through the locations.
• Press the Page Up and Page Down buttons on your keyboard.
• Click the down arrow next to the location in the middle and select another location from the list.

To Set Up the Locations

See the third chapter of this Reference (Prepare session recording) for the procedure. Follow the procedure for each location.

Note: If you selected only two locations, the second is displayed on the left as well as on the right in the carousel control.

Note: The Separate Sessions button is enabled once you have selected multiple locations. Separate session recording is supported with a maximum number of eight locations with two cameras each.

Select Multiple Locations to Record a Composite Session

Aim: To select multiple locations for simultaneous recording. All recordings are combined in one session.

Prerequisites

• The setup account enabled multiple-location recording.
• Your user role allows session recording (Technician, Administrator, or Trainer).

Procedure

1. In the Locations tab, select the locations.
2. Click the Composite session button on the toolbar. A preview of the cameras in the location that you selected first appears. The toolbar displays the carousel control.

See The Carousel Control and To Open Locations with the Carousel Control to set up the locations.

See the third chapter of this Reference (Prepare session recording) for the procedure. Follow the procedure for each location.

Note: The Composite Session button is enabled once you have selected multiple locations.

Note: Composite session recording is supported with a maximum number of eight locations with two cameras each.

Record Sessions

Aim: To create recordings with all cameras in the selected locations.

Important: Do not log in with a browser to a camera while recording with Viso. This may lead to malfunctioning of the Viso system.

Prerequisites

• Your user role allows session recording (Technician, Administrator, or Trainer).
• You have opened a location. See Select Locations for Recording.
• You are satisfied with all settings. See the third chapter of this Reference (Prepare session recording).

Procedure

1. If your license includes the Annotation Module, optionally select a Codes list.
2. Click the record button at the bottom of your window. Next to the button the text Recording appears and the recording duration is shown.

   Tip: It is also possible to view locations and start and stop recording with a web browser. See The Viso Web App.

3. Optionally, score events and make remarks (if you have the Annotation Module).
4. Optionally, talk to the people in the location with the Talk to people in location functionality.
5. To start recording in other locations, click the Back button at the top of the window to return to the Viso start window. Repeat the steps above to start recording in other locations.
6. To stop recording, open the location if it is not already open, then click the stop recording button.

   Note: If you selected multiple locations for separate or composite session recording, pressing the stop recording button in one location stops recording in all locations.

7. A question appears whether you want to stop the session. Click Yes. The following steps depend on whether you recorded a single session, selected multiple locations for separate sessions, or selected multiple locations for a composite session.

If You Recorded a Single Session

• If you did not specify a default session name, a Save session window appears. Enter a name and click Save session.
• If you specified a default session name, the session automatically gets this name followed by a consecutive number.
• If you selected the option to edit the default session name before saving, each session automatically gets the same default name. Optionally, edit this name before you save it.

See also Specify a Default Session Name.

If You Started Recording in Multiple Locations Manually

You must stop recording in each location separately. After stopping a session, click the Back button on the toolbar and open the next location to stop recording there. See If You Recorded a Single Session for how session naming is done.

If You Selected Multiple Locations for Separate Session Recording

• If you did not specify a default session name, a Save session window appears once. Enter a name and click Save session. Each session gets the same name.
• If you specified a default session name, each session automatically gets this name followed by the same consecutive number.
• If you selected the option to edit the default session name before saving, each session automatically gets the same default name. Optionally, edit this name before you save.

See Select Multiple Locations to Record Separate Sessions for Each Location.

If You Selected Multiple Locations for a Composite Session Recording

The result of your recording is a single session. See If You Recorded a Single Session for how session naming is done. See also Select Multiple Locations to Record a Composite Session.

Notes

• Session recording can only be stopped by the user that started the recording, or by a Technician.
• You can also view locations and start and stop recording with a web browser. See The Viso Web App.
• Recording stops automatically if the computer that stores the video files runs out of disc space. This is shown in the session name. Contact your colleague who manages the Viso setup if this happens.
• If you log out while a session is being recorded, recording continues, even if you shut down the computer with Viso. Log in again to stop the recording.
• The Status column in the Locations tab shows in which locations recording is taking place and by which user.
• Locations that are locked or in which recording is taking place can be opened and viewed by others if they have the rights to. However, session recording is disabled for those users. Locations that are offline are not selected for recording by a colleague who has the user role Technician.
• There can be multiple sessions with the same name. Sessions with the same name can be distinguished in the sessions list by the recording date and time.

Tip: Click one of the column headers to sort the locations by name or status, for example to list all locations in which recording is taking place in the first lines of the table.

See Review Sessions.

Review Sessions

Aim: To play back recorded sessions. If your license includes the Annotation Module, you can also play back the scored markers and events.

Prerequisites

• You either have rights to review the session (Technician, Administrator), you created the session (Trainer), you have received ownership or annotator rights, or you are invited to view the session.

Procedure

1. Open the Sessions tab for a list of all sessions.
2. Double-click a row to open a session.
3. Click the play button to play it back.

To Review an Event

If you want to play back a specific event, set a pre-roll interval to start playing a few seconds prior to the event.

1. Click the menu button, choose Settings and then Playback settings.
2. Set the duration of the pre-roll interval and click OK.

By default the pre-roll interval is set to 5 seconds. The maximum duration you can set is 15 seconds. If you do not want a pre-roll, set the value to 0.

To Review a Composite Session

If your session consists of multiple locations, use the carousel control to view the different locations. See To Open Locations with the Carousel Control.

To Change the Video Layout

Optionally, change the video layout in the same way as with recording sessions. See Video Layout.

To Change the Audio

Optionally, change the playback audio in the same way as with recording sessions. See Change Audio Source and Volume in Preview.

To Review the Last Time Fragment

Click the quick review button to let the video jump back and replay the episode. Click it multiple times to replay a longer episode.

By default, the video jumps back five seconds. To select another time interval, click the Menu button at the top of the Viso window and choose Settings > Playback settings. Next, specify the interval. You can also control here whether you want to pause after quick review or continue the playback.

Session Sorting Options

Click one of the column headers to sort the sessions by name, date, location, the person that owns the session, or the person that has been assigned as the annotator.

To group sessions, for example by the user that created them, drag that column header (for example, Created by) to the top of the table. Unfold a group to see the individual sessions. Click the red cross to remove grouping.

You can drag multiple column headers to the top of the table to make groups and subgroups of sessions.

Present Sessions

Aim: To present a session full screen on another screen, for example with a projector or on a large monitor in a debriefing room.

Prerequisites

• You connected the Viso computer to a secondary display and selected this as an extended display. To do so, press Windows key + P and select Extend.
• You either have rights to present the session (Technician, Administrator), you created the session (Trainer), you have received ownership or annotator rights, or you are invited to view the session.

Procedure

1. Open a session. See Review Sessions.
2. If you have a composite session, select the location to display. See To Open Locations with the Carousel Control.
3. Optionally, change the Video Layout or Change Audio Source and Volume in Preview.
4. Click the settings button on the toolbar to open the View Settings pane.
5. Choose the display from the Presentation display list.

Note: Markers and remarks that are scored with the Annotation Module are not shown on the second display. This way you can debrief the session while the audience cannot see your annotations. This is especially useful if the markers and remarks are confidential, or if you debrief a session with students and do not want them to see your annotations about them.

Note: If you connect a display while Viso is open, close and restart the program. The new display will then be visible in Viso.

Manage Sessions

Aim: To rename or delete sessions, change the annotator or the owner of a session, import videos, or export videos for external use.

Prerequisites

• Technicians can manage sessions of all users. Administrators can manage sessions owned by users of their department. Trainers can manage their own sessions, sessions of which they received ownership, and sessions for which they received annotator rights. Trainees can manage sessions of which they received ownership.
• You have opened the Sessions tab.
• Make sure the Recorder Manager is running during these actions.

Rename Sessions

Right-click a session and select Rename.

Delete Sessions

Right-click a session and select Delete. Please note that this also deletes all videos from the session.

Secure/Unsecure Sessions

Sessions will be auto-deleted, by default after 90 days, if the colleague who maintains the Viso setup selected this option in the settings. To retain a session, right-click it in the Sessions list and select Secure/unsecure. The Retention column in the Sessions list shows whether a session has been secured.

Change the Annotator

In the session list under Annotator you can see who has been assigned the role of annotator. Right-click a session and select Change annotator to assign the right to annotate the session to another user. By default, the annotator is the person who recorded the session. This person can assign the role of annotator to a colleague or a student, or reclaim the role of annotator.

Change the Owner of a Session

Session owners can manage sessions (delete and rename sessions, etc.). In the session list under Owner you can see who is the session owner. Right-click a session and select Change owner to give another user the right to manage the session. If you transfer the ownership of a session to another user, that user will automatically be assigned as the annotator of the session.

Export Videos

1. To export videos, for example to use them in a presentation, right-click the session and select Export videos.
2. Specify the destination folder where the videos will be exported.
3. Choose whether you want to export separate videos or combine all videos into one picture-by-picture video per location.
4. Press Export.

Import Videos

To import a video, right-click anywhere in the session list and select Import videos. Alternatively, click the Menu button at the top of the Viso window and choose Import videos.

The selected videos will be added to a new session, and the files are copied to one of the available video locations used by Viso.

On the Import video dialog, the following must be specified:

• The name of the videos to import.
• The newly created session name.
• The Location (you must define at least one location before you can import videos).

The imported session name defaults to the title of the first video, but it can be modified after the video selection.

The video files will be copied to one of the available video locations used by Viso. The preferred destination is the folder used for moving sessions to (a user with the user role Technician is able to set this up). Alternatively, the video folder of the Viso Recorder Manager can be used as a destination. There must be enough space on those file locations for the newly imported video files.

Up to 4 videos can be selected at once, and all will be added to the same new session. It is assumed that the videos are all created at the same time; they must have the same start date and time, with a maximum deviance of 5 seconds. There is no separate synchronization option.

Currently it is not possible to create composite sessions through importing videos, or to add videos to existing sessions.

The imported videos must be .mp4 files or .mov files with H264 encoding and AAC audio. In the case of .mov files, they are converted to .mp4 on import.

Creating H264 Videos on New Apple Devices

Some newer Apple devices create MOV files using the HEVC (H265) format. This format is not recognised on Windows 10 and Windows 11 by default, and is not supported in Viso. You can set these devices to capture media using the older formats, which are more broadly compatible with other devices and operating systems:

1. Go to Settings > Camera.
2. Tap Formats.
3. Tap Most Compatible. This setting is available only on devices that can capture media in HEIF or HEVC format, and only when using iOS 11 or later.

All new photos and videos will now use JPEG or H.264 format. To return to using the space-saving HEIF and HEVC formats, choose High Efficiency.

The Annotation Module

If your Viso license includes the Annotation Module, you can mark events that are of interest for your study. For example, in a classroom, the onset of the Instruction phase and the Group work phase. Optionally, link markers to subjects, for example to mark a question by the teacher and the answer by a student. Markers specify a moment and have no duration.
