Movie Player
The film jumps to another position when I start playing. Several films are protected by copyright. For this reason we only use short fragments of these protected movies: film quotes. When a particular excerpt is longer than the film quote, the movie player will only play the quote part.
For example, if an excerpt has a duration of 300 seconds and we use the part between second 50 and 100 as a film quote, you cannot play the first (0-50) and the last part (100-300). The accessible range is indicated in the player. Top left shows the start second; top right the end second.

Brightness
Some excerpt may appear a little dark. In such a case, you can adjust the brightness of your screen. With laptops you can usually change the settings with
- Less bright: Fn-key + arrow left
- More bright: Fn-key + arrow right.

Sound
The sound dynamics between the excerpts have a large range. There are two volume sliders which allow you to adjust the sound level of each individual excerpt. In this context it is advised (especially with laptops) to connect separate speakers to the speaker port.
