FIXED objects / watermarks
A sticker or caption can be displayed for the entire duration of a video. For example, you may want to include your logo or something like a “Please subscribe” message.
Select the video on the Recordings tab and click the Edit Video button
Add a sticker or caption to your video (or click on one that has already been added)
Enable the Make fixed overlay option.
The sticker / caption will be hidden on the timeline but it will still appear in the video. Click on it in the video to make changes to it.
TIP To give a sticker / caption a watermark effect, reduce the Opacity of it.
