Important: The first time you launch Mosaic, you will be asked to allow it access to your Camera and Microphone. Please click Yes for both as you will not be able to record if you don't allow this.

Recording using Mediasite Mosaic

This new application features a simple recording interface.  To record, simply choose the inputs you'd like to record and then click the Record button.

To record, you must first select an audio device. 

To do this, click on the microphone icon in the top left (shown below):

Microphone input

Click on the microphone you want to use. A headset is recommended for best quality. Once it is highlighted blue, this means it is selected and will be used for recording.

Microphone input selected

You can do the same for the webcam icon if you'd like to record video. This is optional.

To record your display, click on the display icon.

Choose display

Important: If you select a specific window, Mosaic will only record this window. If you want to record more than one application, we recommend selecting Share your display and this will ensure your whole screen is captured. If you want to record a PowerPoint Presentation in slideshow mode, please make sure you select 'Share your display' to ensure your slideshow is recorded.

Share your display

Once you have selected all the inputs you want to record, click on the Record button at the bottom of Mediasite Mosaic.

Record in Mosaic

Important: Mosaic will remember the microphone and webcam inputs you select the next time the application opens so you don't have to select them each time. However, you will need to choose your display or window each time.

After clicking Record, Mosaic will count down and then the recording will begin. You can pause or end the recording by clicking on the Mosaic icon in the taskbar and clicking Pause or Stop (shown below):

Stop or pause recording

Once you stop the recording, this will automatically be uploaded to Mediasite.

You can check this by clicking on the Presentations tab. The status will say Uploaded and you will receive an email from Mediasite once the recording is ready to be shared in Mediasite.

Bulk upload using Mediasite Mosaic

Mosaic allows you to bulk upload MP4 videos to Mediasite. The quickest way to do this is to copy all of the videos you want to upload to Mediasite into a single folder (for example, on your Desktop). 

Next, click on the three dots (...) in the top right corner of Mosaic and choose Settings.

Settings in Mediasite Mosaic

Under the 'Import' heading, select 'Automatically upload imported presentations to My Mediasite'.


Now, click the Presentations tab in the top left of Mosaic.

Click Import (at the top right) then Import Folder.

Browse for the the folder with your videos in and click 'Select Folder'.

Import Folder option

The videos will then automatically import into Mosaic and upload to Mediasite. Please do not close Mosaic until they have uploaded. 

Once uploaded, you will receive an email when they are available to watch in Mediasite

You can also click 'Add Watch Folder' and choose the folder that contains your videos. This means video files from any source can be added to a watched folder and then automatically be uploaded to Mediasite. Mosaic then watches for new content added to this folder and will automatically upload it if the options are configured.

Important: If you are planning to use the bulk upload feature in Mosaic, it is important to manage your content in Mediasite. Please see this article on managing quotas in Mediasite and moving content to module folders where appropriate.
