Compatibility and technical requirements for run/stop cables with Red Epic cameras and follow focus systems

14 years old. Gear and prices may have changed since.

What the thread found

  • The Red One start/stop cable is not compatible with the Epic-X due to different connector pinouts and electrical requirements.
  • The Epic uses a 00-pin 4-pin Lemo connector that outputs timecode information and GPIO signals.
  • To trigger recording on an Epic, the GPIO pin must be pulled to 3.3 volts and held at that level, requiring a specialized cable design.
  • A run/stop solution for Epic cameras using wireless follow focus receivers typically requires multiple components: a trigger box, a power cable with 2-pin Lemo connector, a 4-pin Lemo start/stop cable, and a separate Lemo-to-BNC breakout cable.
  • Third-party manufacturers including Preston, Cmotion, and others developed Epic-compatible run/stop cables to address the gap left by Red's connector design.

Depends on

  • Discussion reflects equipment and availability status as of 2012.
  • Some participants expressed preference for different cable designs and power delivery methods, indicating no single solution satisfied all users.
  • The complexity of the system and reliance on multiple cables was noted as a limitation.
  • Compatibility with specific follow focus receivers such as analog versus digital versions varies depending on cable design.
