Problem
A camera's dual-card relay mode is configured incorrectly, so the second card receives proxy media rather than the intended safety copy.
Solution
Root Cause / Diagnostic:
Mirrorless and cinema camera firmware menus often feature multiple multi-card recording options (Relay, Backup/Simultaneous, Raw+Proxy, Photo/Video Split). Accidental misconfiguration results in slot 2 recording low-bitrate 1080p proxy files instead of bit-for-bit redundant master takes.
Actionable Fix:
1. Menu Redundancy Lockdown: Access camera recording settings and explicitly set Slot 2 recording mode to "Simultaneous Recording" (or "Backup Rec") with matching codec, resolution, and frame rate settings.
2. Configuration Preset Export: Save the confirmed backup configuration to camera memory bank presets (C1/C2) and export the config file to an administrative SD card.
3. Dual-Card Offload Audit: After the first test shot of every production day, mount both cards side-by-side to verify identical file sizes and codec bitrates across both volumes.
Pro Tip:
Lock your production camera settings into custom profile presets (C1/C2/C3); never rely on manual menu navigation on set to configure dual-card backup recording.
