Video signal corruption on Arri 3 high-speed setup resolved through separate power configuration
16 years old. Gear and prices may have changed since.
What the thread found
- A video tap powered through the same camera body as a high-speed base can cause grounding issues resulting in scrambled video output
- Powering the video tap with an independent power source separate from the camera eliminates the grounding-related video corruption
- Removing the magazine from an Arri 3 and rolling the camera alone produces clean video, indicating the issue is related to the mag and power distribution setup rather than the camera itself
Depends on
- This was a known issue primarily encountered with older Arri 3 video systems and may not apply to modern camera configurations
- The workaround described (using high-speed base power for the tap instead) only functions when high-speed frame rates are not required
- Specific video tap model and exact camera configuration details are unclear from the discussion
