Cinematographer
Blood Rigs ermöglichen kontrollierte, wiederholbare Bluteffekte. Im Gegensatz zu Squibs kann ich mehrere Takes bekommen – wichtig für komplexe Einstellungen mit präzisem Timing.
Mechanical system for delivering controlled blood flow effects on set – pumps, tubes, and reservoirs that create realistic bleeding wounds, severed arteries, or gore effects.
What is a Blood Rig?
A Blood Rig is a mechanical system for the controlled delivery of artificial blood on set. It comprises pumps, reservoirs, tubing, and valves, enabling precise blood effects – from continuous oozing to pulsating arterial fountains.
Components
| Element | Function |
|---|---|
| Reservoir | Artificial blood container |
| Pump | Pressure generation |
| Tubing | Blood supply to wound |
| Valves | Flow control |
| Trigger | Activation |
| Nozzles | Spray pattern shaping |
Pump Types
| Type | Characteristics |
|---|---|
| Hand Pump | Simple, manually controlled |
| Electric Pump | Constant pressure |
| Pneumatic | High pressure, fast |
| Gravity | Natural, slow flow |
| Peristaltic | Pulsating, arterial-like |
Effect Types
| Effect | Rig Configuration |
|---|---|
| Oozing | Low pressure, narrow nozzle |
| Flowing | Medium pressure, open outlet |
| Splattering | High pressure, precise nozzle |
| Pulsating | Peristaltic, rhythmic |
| Fountain | Maximum pressure, wide opening |
Application Areas
| Scenario | Rig Type |
|---|---|
| Cut Wound | Gravity/Hand pump |
| Head Wound | Concealed reservoir |
| Arterial Injury | Peristaltic, pulsating |
| Amputation | High pressure, high volume |
| Mouth Blood | Special mouthpiece |
Setup
| Step | Activity |
|---|---|
| Planning | Effect design, determine volume |
| Preparation | Lay and conceal tubing |
| Positioning | Under costume/prosthetic |
| Testing | Test off-frame |
| Calibration | Adjust pressure/flow |
| Action | Trigger at the right moment |
Concealing the Technology
| Method | Description |
|---|---|
| Under Costume | Tubing along the body |
| In Prosthetic | Integrated system |
| Behind Set Elements | Run out of frame |
| Wireless Trigger | No visible cables |
Artificial Blood Considerations
| Factor | Adjustment |
|---|---|
| Viscosity | Thin for spray, thick for oozing |
| Color | Light for fresh, dark for venous |
| Temperature | Body temperature for realism |
| Volume | Calculate per shot |
Safety
| Measure | Description |
|---|---|
| Pressure Limiting | Define maximum pressure |
| Skin Compatibility | Test blood on actors |
| Slip Hazard | Floor covering |
| Cleanup | Prepare for set cleaning |
Advantages over Squibs
| Aspect | Blood Rig | Squib |
|---|---|---|
| Repeatable | Yes | No |
| Continuous | Yes | Single-shot |
| Safety | No pyrotechnics | Explosive |
| Control | Precisely controllable | Limited |
Challenges
| Problem | Solution |
|---|---|
| Air Bubbles | Bleed the system |
| Clogging | Check and clean nozzles |
| Timing | Rehearse, communicate |
| Volume | Large reservoir |
Costs (approx.)
| Element | Price |
|---|---|
| Simple Rig | €200–500 |
| Professional System | €1,000–3,000 |
| Artificial Blood (Bulk) | €50–150/5L |
| SFX Technician | €400–800/day |
Today
Blood rigs remain an essential tool for practical blood effects. The combination of control, repeatability, and realism makes them indispensable – from subtle injuries to over-the-top gore in horror and action.
From the crafts
Perspectives
Director
Mit einem Blood Rig habe ich Kontrolle über Menge, Druck und Timing des Blutflusses. Von subtiler Wunde bis zur Fontäne – alles ist steuerbar und wiederholbar.
Producer
Blood Rigs sind komplexer als einfache Squibs, aber wiederverwendbar. Für Szenen mit mehreren Takes oder kontinuierlichem Blutfluss sind sie kosteneffizienter.
