Selecting a Video Frame or Document Page to set as Item Thumbnail
Although Airship will automatically generate a thumbnail image for content, admins have the option to manually select a video frame or document page to set as the thumbnail image.
Within Airship, click on Media (1), and select Media Management (2) from the dropdown.
Navigate to the content for which you'd like to update the thumbnail; click on the item name (3) or the Edit icon (4).
On the File Info tab, locate the Thumbnail section (5). Click Pick a Frame from the Video (6).
NOTE: If updating the thumbnail for a document rather than a video, click Pick a Page from the Document.
Available video frames (or document pages) will pop-up. Select the desired thumbnail (7); click Save (8).
The selected image will now appear as the new thumbnail in Airship and the apps. Make sure to click Save on the File Info tab.
