# Video and Slide Controls

Use the video controls to control playback, seek within or skip back in the presentation, view full-screen video, and adjust the video playback speed. When you are viewing a live presentation, you cannot pause, skip back, or seek within the presentation. Also, you cannot adjust the video playback speed. When a presentation is live, the live presentation indicator is shown. Note: If the video for the presentation does not appear, verify the presentation is not an audio-only presentation and that your computer meets the requirements listed here. ## Play, pause, and skip back
Play | Pause | Skip back
Click Play to resume playback after pausing the presentation. Presentations automatically start playing when the Player is launched. Click Pause to suspend playback. Click Skip Back to go back 3 seconds in the presentation. ## Use the video seek bar
Use the video seek bar to move backward or forward in the presentation. Top ## Adjust video playback speed
Adjust Playback Rate
Click Adjust Playback Rate to increase or decrease the playback speed of an on-demand presentation. This feature is not available in all scenarios. ## Adjust volume
Volume/Mute
Adjust the volume by moving the Volume slider up or down. Click Mute to turn the audio off. Click it again to turn it back on. Top ## Navigate slides
In on-demand and portable presentations, slides are displayed in a carousel with the current slide being more prominent. In its default state, the slide carousel tracks/scrolls as the presentation plays, keeping the thumbnail for the current slide near the center. Select a slide thumbnail in the carousel and drag it to scroll through the available slides. Click on a slide thumbnail to navigate to the time in the presentation when the slide first appears. You cannot navigate slides during a live presentation. ### Slide stacking To simplify thumbnail navigation, Mediasite Players stack slides when there are a large number of images captured over a short period of time. If a slide appears sooner than 2 seconds after another slide, it will form a stack. The Player will continue adding slides to the stack until the stack reaches a limit of 10 or if the timing goes beyond 2 seconds since the last slide. Each stack can contain no more than 20 seconds worth of content. Presentations with 25 or less slides will not have any stacking. To view each slide in a stack individually, click on the stack of slides. ## Preview slide Place your mouse on a slide thumbnail for a few seconds to preview it. In preview mode, you will see a larger view of the slide as well as its slide title and slide description (if available). The slide preview has a distinct yellow border around it. As long as the mouse cursor remains over a slide thumbnail, the carousel will not resume automatic tracking with the presentation. When you move the mouse to another slide in the carousel, the preview changes accordingly. To exit preview mode, move the mouse from the slide thumbnail. Top ## Zoom in, zoom out, and pan slide image
Zoom In | Zoom Out
Click Zoom in to get a closer view of the slide image. Once you zoom in to an image, use the mouse to pan the slide image at the selected magnification. Click Zoom Out to get a wider view of the image. Note: When using the zoom feature, you can drag the image around to see parts of the image not shown in the viewing area. Top ## Bookmarks Mediasite bookmarks (saves the last point viewed) the last ten on-demand presentations viewed from the same computer. When you close a presentation before it is finished, a bookmark is created so that you can resume viewing the presentation at the same point later. For example, if you are viewing a presentation and exit the window at 3:17 minutes into the presentation when you launch the presentation again (from the same computer), the presentation will begin playing at 3:17 minutes. Note: In order for bookmarking to work, application storage must be enabled in Microsoft Silverlight. This feature is enabled by default. If bookmarking is not working verify this feature is enabled on your computer: Right-click on the Silverlight Player and select Silverlight. Click the Application Storage tab. If this feature is enabled there should be a check in the Enable application storage check box. Top
