NoldusViso – Review and present sessions

Last updated: Nov 09, 2026

Reviewing a session lets you replay the recording, navigate it with playback controls or by jumping marker to marker at different speeds, and add, edit, or remove annotations while you watch. Views can be rearranged, enlarged, or shrunk during review.

Note: To let others watch or annotate on their own computer, share the session with them — see Share sessions. Any annotations they add end up on the timeline and in the annotation log, the same as your own.

Prerequisites

1. Opening a session for review

  1. Go to the Library tab in the menu.
  2. Find the session's card and click it; a Play arrow appears over the preview when you point at the card. Other actions available from the card (rename, share, delete, and so on) are covered in Manage and Export Sessions.
  3. The session opens on screen.
  4. Click Play to start the replay.

3. Adding, editing, and removing annotations

If annotations were added during recording, they're visible on the timeline and in the annotation log. While reviewing, you can add, edit, or remove them:

  • Adding an annotation — click a subject, task, or event to add it during the review. It's added to the timeline.
  • Editing or deleting an event — best done with the replay paused: go to the event on the timeline and click it (or click its entry in the annotation log). A small edit panel appears above the timeline: choose another event in its drop-down to change it, use the bin icon to delete it, or click x to close the panel.
  • Editing or deleting a task — go to the task on the timeline and click it (or click its entry in the annotation log). In the edit panel, choose another task in the drop-down to change it, or use the bin icon to delete it. Alternatively, click the task's start or end point and slide it to adjust its duration.
  • Zoom in/out on the timeline for a more detailed view, with the magnifier buttons or the slider at the left of the playback bar.
  • Adjust playback speed (see above) to time events and tasks precisely against what happens in the video.

4. Changing view settings

Click a video pane to enlarge or shrink it. To show one video in a window of its own, use its pop-out button (see "Presenting the session" below).

The Subjects button at the top left of the timeline shows the rows of every subject or only those of the active subject.

5. Using the annotation log

The annotation log shows a chronological overview of all annotated tasks and events. Use the Filter button to show only specific events, tasks, subjects or comments. When you click on a task or event in the annotation log, the playhead in the timeline jumps to that annotation.

6. General controls

A few controls are available throughout the review screen:

  • Hide or show the event controls and the timeline with the chevron button (Hide event controls and timeline / Show event controls and timeline) at the right of the bottom bar.
  • Collapse or expand the annotation log with the Open annotation log / Close annotation log button (tasklist icon) at the right of the bottom bar.
  • Download, share, rename, or delete the session via the three-dot Session actions menu next to the session's name at the top — see Manage and Export Sessions for details on each action. The same menu has Edit events and tasks, which changes the events, tasks and subjects offered for this session.

7. Presenting the session

To show the videos to an audience, for example on a projector, put them in a window of their own while you keep every control in yours. This works the same way while you observe a live session.

  • All videos: click Pop out videos at the bottom right. The new window shows the view's videos as they are laid out here, including an enlarged video.
  • One video: click the pop-out button on that video. You can pop out several videos, each in its own window.

In Chrome and Edge a pop-out moves to your second screen by itself; the browser asks for permission once. Click Full screen in the pop-out to fill that screen. Playing, pausing, jumping and the playback speed all follow the window you work in, and sound plays from your computer as usual. Click the same button again, or close the pop-out, to end it.
