Create video thumbnail profiles

You create and define video thumbnails from the advanced settings.
To do this, perform the following:

  1. Navigate to Administration » Settings » Advanced.
  2. In the left pane, expand Libraries » Videos and click Profiles.
  3. Click Create new.
  4. In Name, enter a descriptive name for the video thumbnail profile.

    Do not use spaces. For example, enter Thumb100x100
  6. In Resize Method, enter one of the following:
    • CropCropArguments
      The thumbnail image will be cropped to area - the original image is cropped from all sides evenly, so that it fits the thumbnail size.
    • ResizeFitToAreaArguments
      The thumbnail image is resized to fit the area - when the proportion of the original thumbnail dimensions is different from this of the predefined thumbnail, the images are resized so that the longer side of the image fits the respective side of the thumbnail. Images are aligned up and to the left of the predefined thumbnail.
  7. If you want to make this thumbnail default when creating a library, select Marks a profile as a default one when creating a new library.
  8. You can choose which thumbnails to hide or display in specific widgets, using the Tags field.
