Uploading caption files manually

You can add closed captions to on-demand presentations manually by creating caption files and uploading them to the presentation. You can create the files yourself using Caption Editor, a third-party captioning software, or a captioning service. Users can search closed caption text in players, and video collections for specific words and phrases.

When adding captions to a presentation by uploading caption files, consider the following:

• Mediasite supports Synchronized Accessible Media Interchange (SAMI), SubRip (SRT), Web Video Text Tracks (VTT), and Distribution Format Exchange Profile (DFXP) files.

• Non-English captions must be saved with UTF-8-character encodings. For more information, see KBA000004029 on the Customer Assurance Portal.

• Mediasite supports begin and end times in DXFP so you can specify expiration times, that is, how long captions remain on screen.

• Mediasite supports DFXP caption files containing multiple languages. However, you can only edit the primary language in Caption Editor. To edit captions in the remaining languages, you must edit the file outside of Mediasite. We strongly recommend editing the presentation prior to creating caption files.

• When you update caption files using Mediasite’s Caption Editor, you can download the edited captions as a DFXP file.

2. If you have not already enabled captioning, select the Audio Transcriptions check box.

3. Select the Manual Upload radio button and click Select a file to locate and select your closed caption file. Click Upload. Click the Save button.

4. Once the file is uploaded, launch the presentation in Mediasite Player and verify your captions appear as expected.

Users can use Caption Editor, available in My Mediasite to create and edit captions if they do not have a captions file to upload. Users can automate the captioning process using Mediasite Captioning, which is powered by Vidable™. Mediasite Captioning does not require users to have an external captioning service account. Mediasite also allows users to automate the captioning process using Automatic Sync Technologies® (AST), 3Play Media, and other captioning services. Users must use credentials for an existing account to automate this process. For more information, see Using automated captioning.

Add thumbnail images manually

Mediasite automatically generates a thumbnail from a presentation’s video. However, you can always upload a custom thumbnail image to replace the auto-generated one.

To add a thumbnail image to a presentation:

5. Navigate to your presentation. Click Edit and go to the Delivery tab.

6. Click Select a file and navigate to the image file you want to use for the thumbnail. Click Save.

Adding slide titles and descriptions

Once you record and publish a presentation to Mediasite, you can add slide descriptions and slide titles to the on-demand presentation using Management Portal. Slide descriptions—text describing slide content—may be displayed in place of slide images and can be read by text readers.

To add slide titles and descriptions:

1. Navigate to your presentation and click Edit Slides. This launches the Slide Editor.

2. Click on a slide to enter a title and description for it. Optionally, select the Set as thumbnail check box to make this the thumbnail image for the presentation. Click Save.

3. Once you are done, click Back to exit the Slide Editor.

You can also add chapters to an on-demand presentation using the Mediasite Editor. Chapters are an organized list of key parts of a presentation that allow a viewer to navigate easily to points of the presentation that are most relevant or important. For information on adding chapters to an on-demand presentation using the Web Editor, see the Editor Help file.
