Select your interactive element, drag and drop it where you want in the video.
It is also possible to position a hotspot or a popup with the geometric properties.
Go in the Gemotry tab. Then in the position menu, click on ‘horizontal’ and ‘vertical’. You can directly enter the position of your element with the horizontal value and the vertical value. By default, the horizontal value and the vertical value are relative to the video stream, but you can also make it relative to the player or you can make it absolute.
To make it absolute, you have to disable the button ‘relative’.
How to center an element in the video?
-> In the geometry tab, enter horizontal value = 0.5 and vertical value = 0.5
