Understanding the video properties
For every video you can set the following properties individually:
◆◆Aspect Ratio defines the relation between the width and the
height of your thumbnail. 16:9 and 4:3 are fixed formats. This
means that if you increase the width then the height is also
increased correspondingly. If you select Custom, then you can
set the size anyway you like.
◆◆The Preview Image will show the Youtube/Vimeo thumbnail of
your video in your publication if you set this to Thumbnail. If
you set it to None then the area will be completely transparent
apart from the ‘Play’ button. This is useful if your publication
already contains a suitable image that you want to link to the
video
◆◆Autostart means that the video will automatically start playing
when your users click on the video link. When you deselect this,
then your users will have to manually press the play button in
the pop-up player to start playing the video.
