Once we have created a new presentation, or we have opened one previously created, we can start adding videos.
First, we will have to choose the project or projects from which we want to use the videos from. To do so, we will have to filter the projects. If in the information of a project we fill the following blanks we will be able to filter them in "Presentations".
- Select seasons
- Select competition
- Select teams
If we did not fill those blanks on our project we can also mark the option "not specified" and, in that case, all the event which we did not specify the information will be shown.
Then, we will have to click the icon 
to apply the filter. Once it is been filtered, all the events will appear on the right tab. Those events can be also filtered using the next parameters:
- players
- event type
Finally, when all the filters have bee applied, we will see the events and we can now add them to our presentation. To do so, you only have to drag the event to the timeline.
Tip: If we drag a category, all the event form this category will be added to the timeline. We can also drag more than one event at once, press the ctrl key for Windows or ⌘ key for OSX while we choose the events that we want to add.
Warning: remember to save your project doing click to the icon 
or also you can user the shortcut ctrl+w for Windows or ⌘+w for OSX.
