• The recording speed is expressed in "Frames Per Sec", which means that the camera will record so many times<br />
the second the photographic image of the finish line, and of course also registers the corresponding time for<br />
each frame.<br />
Remember:<br />
- The faster the race, the more frames pro sec you will need to show a good picture.<br />
- The higher the vertical resolution you choose, the more frames pro sec you need to show a<br />
normal picture (f.e. bicycle wheel round and not oval).<br />
- The more light there is available, the more frames you can record pro second.<br />
Guidelines for min & max recording speed, depending on race type<br />
1. Athletics T&F -> 800-1200 l/s (Sprint races)<br />
-> 600-1000 l/s (400-1500m)<br />
-> 400-800 l/s (Long distance)<br />
2. Horse races -> 800-1200 l/s<br />
3. Greyhound races -> 1000-1400 l/s<br />
4. Cycling -> 1400-2000 l/s<br />
5. Canoe & Kayak -> 200-500 l/s<br />
To change the ‘Lines Before’ and ‘Lines After’, (= the amount of lines recorded before and after<br />
interruption of the photocells) click on the number and enter the new amount. By typing here the<br />
desired numbers (1...100) YOU can define how wide the photo is recorded around each athlete, to be<br />
sure that not only the body of the athlete is visible on the photo, but also the arms and legs.<br />
• To select the mode of WindSpeed recording, click ‘None’ and select the required WS-measurement:<br />
Used as :<br />

13s -> 110 meters hurdles race + 100 meters hurdles race<br />
Manual -> 200m race WindSpeed measurement started by dedicated operator<br />
User Mode -> 200m race WindSpeed measurement started by MF operator (see later)<br />
Click the 'Apply' and 'OK' buttons to save the modified parameters:<br />
You can later use this list of recording settings for the recording of real races, by selection in the 'Parameters' window<br />
OR in the 'Scrolling camera view' window.
