Putt-Putt

Compact portable generator (3–8 HP) for location shoots, powering 2–4 HMI lights or LED panels at 230V.

Technical Details

Standard putt-putts operate with 4-stroke gasoline engines between 3-8 HP, delivering 230V AC at 50 Hz. The fuel tank typically holds 5-15 liters, allowing for 3-8 hours of runtime at full load. Modern units feature Schuko and CEE connectors, overload protection, and sound-dampened housings to reduce noise levels to 65-75 dB(A) at one meter. Inverter models produce particularly clean power for sensitive digital equipment, while conventional units are more affordable but exhibit greater voltage fluctuations.

History & Development

The first putt-putts emerged in the 1960s out of the necessity to realize location shoots independently of the public power grid. Honda, starting in 1968 with the E-series, set the standard for quiet, compact film generators. In the 1980s, German manufacturers like Endress introduced specialized film generators. With the advent of digital cameras from 2000 onwards, inverter putt-putts gained importance as they provide the required power quality for sensitive electronics.

Practical Use in Film

Putt-putts typically power 2-4 HMI lights up to 575W or LED panels up to 200W simultaneously. For exterior shoots, they are placed at least 30 meters away from the sound recording area to avoid interference noise. Documentary filmmakers use them for spontaneous interviews, while feature film productions like "The Revenant" (2015) utilized dozens of putt-putts in remote areas. Refueling with gasoline and generator maintenance require dedicated crew members for longer shoots.

Comparison & Alternatives

Unlike large film generators (50-500 kW), putt-putts are only suitable for smaller lighting setups but are significantly more flexible in positioning. Battery storage systems like the Bebob Cube series are increasingly replacing putt-putts for short shoots as they operate completely silently. For larger productions with high power demands, diesel generators from 20 kW upwards are used, which can power multiple lighting groups via distribution boxes.

Perspectives

Cinematographer

Ich positioniere Putt-Putts immer windabgewärts, damit Abgase nicht ins Bild ziehen, und verwende 50-Meter-Kabel um genug Abstand für sauberen Ton zu haben. Bei kritischen Digitalaufnahmen bestehe ich auf Inverter-Modellen, da Spannungsschwankungen bei billigen Aggregaten meine RED-Kamera zum Absturz bringen können. Die Vibrationen übertragen sich nie auf mein Equipment, solange das Aggregat nicht direkt an Stativen oder Schienen steht.

Director

Für mich sind Putt-Putts Ermöglicher authentischer Locations – ich kann in verlassenen Gebäuden oder Naturkulissen drehen, ohne auf Lichtstimmung verzichten zu müssen. Das Motorengeräusch zwingt mich zu bewussterem Sounddesign, aber gibt mir die Freiheit, Geschichten dort zu erzählen, wo sie hingehören. Bei Nachtszenen schaffe ich mit putt-putt-betriebenen HMIs die perfekte Balance zwischen natürlicher Dunkelheit und cineastischer Sichtbarkeit.

Producer

Ein Putt-Putt kostet 800-3000 Euro in der Anschaffung und verbraucht etwa 1-2 Liter Benzin pro Stunde – das macht 30-50 Euro Betriebskosten pro Drehtag. Ich kalkuliere immer einen Backup-Generator ein, da Ausfälle den ganzen Dreh stoppen können. Die Logistik mit Benzinkanistern und Lärmschutz-Abständen braucht extra Planungszeit, aber die Flexibilität bei der Location-Wahl spart oft teure Studio-Mieten.
