ONE

Understanding LongoMatch

1.1 Projects and Database

LongoMatch understands a game analysis like a Project. For each game you will need to create a new Project, that isstored in the program’s database.

A Project contains the following elements:

• A set of properties that describes the match (teams’ names, final result and date)

• A project template (sets the properties of each category)

• A filename that points to video file containing the recorded game

It’s important to know that you cannot create two Projects for the same video file.

The file’s name is used to set the project’s name, so try to use a filename as descriptive as you can.

1.2 Project Templates

LongoMatch lets you tag plays in 20 categories. For each category you can set the following properties:

• A name that describes the category

• A lead time

• A stop time

• A colour to easily identify the category

• The visibility of this category (lets you choose if you want to use it or not)

Each Project has a template that contains the properties of the 20 categories, which lets you customize a project justby editing its template.

When you create a new project you have to select a template to load, that can be the default template or a pre-madedone.

Once this template is loaded into the Project you can edit it to customize the Project depending on the needs of theanalysis.
