Fledermaus

Getting Started

Welcome to the Fledermaus 8 quick start guide. As a new user, please follow this guide to help you get familiar with the Fledermaus 8 functionality to make a movie in few steps.

To start working with Fledermaus, you need to have it installed. For information on installing, please refer to Fledermaus Hardware requirements and Fledermaus Operating Systems Requirements. For Licensing installation and usage please refer to How-to Softlock Licenses Technical for QPS products.

Working with Fledermaus 8 you will be prompted to work with a Scene or a Project. This guide explains how to work with Scene, which is the traditional way of working with Fledermaus.

The data used for this guide is the single head EM2040C data from Brest, France, that was acquired using Qinsy and was provided to QPS by Universit√© de Brest; these files are available for download.


Step-by-Step

Step 1: Create a Scene

  1. When you open Fledermaus 8 you will have a choice of making Scene or selecting any of the available QPS projects on your computer. 
  2. To make a Scene click Close in the dialog as shown in Figure 1.
