The Blackmagic Design Spares - Camera URSA Mini - SSD Record Mount Plate is the specialized mechanical interface designed to bridge the Blackmagic URSA Mini SSD Recorder (or the URSA VLock/Gold Mount Battery Plate) to the back of the URSA Mini chassis.
While it may appear to be a simple metal plate, it serves as the critical structural foundation that ensures high-speed data and power connections remain stable under the weight of heavy batteries and external SSD media.
Functional Role
This plate is required when expanding the storage or power capabilities of the camera.
-
Mechanical Alignment: It ensures that the high-density multi-pin connector on the back of the camera aligns perfectly with the pins on the URSA Mini SSD Recorder or a battery plate.
-
Structural Load Bearing: It transfers the weight of a 98Wh+ battery and an SSD recorder directly to the camera’s magnesium frame, preventing stress on the internal electronic headers.
-
Cable Management: The plate includes specific cutouts and channels to allow the internal SDI and power looms to pass through from the camera body to the recording module without being pinched.
Compatible Models
This plate is universal for the "Mini" chassis ecosystem, including:
-
URSA Mini 4K / 4.6K
-
URSA Mini Pro 4.6K (G1 & G2)
-
URSA Mini Pro 12K / 12K OLPF
-
URSA Broadcast / Broadcast G2
When to Replace the Mount Plate
-
Stripped Threads: The four primary mounting holes that secure the battery plate or SSD recorder can become stripped after frequent changes between "Studio" and "Handheld" configurations.
-
Warping/Bending: If the camera is dropped on its "rear," this plate can bend. Even a millimeter of warp can prevent the SSD recorder from making a clean electrical connection with the camera, leading to "Disk Not Found" errors.
-
Connection Fatigue: If the SSD recorder feels "wobbly" even when the screws are tight, the mounting plate or its internal standoffs have likely suffered structural fatigue.
-
Corrosion/Environmental Damage: For cameras used in coastal or humid environments, the metal can oxidize, leading to "seized" screws that may snap during attempted maintenance.
Key Features
-
Heavy-Duty Aluminum/Magnesium Construction: Designed to withstand the constant "tug and pull" of swapping batteries.
-
Precision Machined: Guaranteed to match the screw-hole pattern of the URSA Mini SSD Recorder and the URSA V-Mount Battery Plate.
-
OEM Finish: Features the same scratch-resistant matte black coating as the rest of the URSA lineup.
Technical Installation Note
Installing or replacing this plate is a "Level 1" task, but it requires careful attention to the camera's rear interface.
-
Protect the Pins: When the plate is removed, the multi-pin "umbilical" connector on the back of the camera is exposed. Do not touch these pins with your fingers. Skin oils can cause high-speed data errors (SDI data corruption) or poor power conductivity.
-
Cable Routing: If your setup involves the external BNC "loop-out" cable for the SSD recorder, ensure the cable is routed through the plate's cutout before you tighten the screws.
-
The "Star" Pattern: When mounting the plate to the camera, start all four screws by hand first. Tighten them in a diagonal pattern to ensure the plate is perfectly flush. If it sits at an angle, your SSD recorder will have intermittent connection issues.
-
Screw Selection: Only use the screws provided by Blackmagic. Third-party screws that are too long can penetrate the camera's rear casing and damage the internal Power Distribution PCB.
Expert Tip: If you are experiencing "Recording Interrupted" errors, it is often due to the screws on this plate being slightly loose, causing the SSD recorder to vibrate and lose its data connection. Tightening this plate is the first step in troubleshooting SSD recording issues!
Are you installing a new SSD Recorder for the first time, or are you replacing a damaged plate to fix a "wobbly" battery mount?
