Sony VMC-BNCU1: Professional Timecode Synchronization for the Sony FX5

Connect Your Sony FX5 to an External Timecode Source

The Sony VMC-BNCU1 is a professional adapter cable developed by Sony to allow the Sony FX5 Cinema Camera to receive or synchronize with an external timecode source.

Featuring a USB-C male connector for the camera and a BNC female connector for external equipment, it enables the FX5 to integrate seamlessly into professional production environments where multiple devices share a common time reference.

This adapter makes it possible to synchronize cameras, external audio recorders, and other compatible equipment so that every recording shares the same highly accurate timing information.

Why Use Timecode?

Timecode is a precise timing reference recorded alongside video and audio.

Unlike a simple internal clock, timecode ensures that multiple devices remain synchronized throughout an entire production.

This greatly simplifies post-production, especially when combining footage from several cameras or synchronizing externally recorded audio.

Timecode is widely used in:

• feature film production;
• documentaries;
• television broadcasting;
• live concerts;
• live events;
• multicamera interviews;
• commercial productions;
• corporate video production.

Reliable Synchronization Between Multiple Devices

When connected to an external timecode generator, the Sony VMC-BNCU1 allows the Sony FX5 to operate alongside other devices using the same timing reference.

This workflow is particularly valuable for productions involving:

• multiple cameras;
• external audio recorders;
• electronic slates;
• dedicated timecode generators;
• complex production systems.

Each video and audio file is recorded with matching timecode information, making synchronization during editing significantly faster and more accurate.

USB-C to BNC Connection

The Sony VMC-BNCU1 features two connectors specifically designed for professional timecode applications:

• a USB-C male connector for the Sony FX5;
• a BNC female connector for an external timecode source.

BNC is the industry-standard connector for professional synchronization signals and provides a secure, reliable connection with professional timecode generators.

Compatible with Professional Timecode Generators

The Sony VMC-BNCU1 can be used with many professional timecode generators equipped with a BNC output.

Depending on the production workflow, it can be integrated with solutions such as:

• Tentacle Sync;
• Deity TC-1;
• Ambient Recording systems;
• Atomos UltraSync;
• and other compatible BNC-equipped timecode generators.

The choice of generator naturally depends on the specific production requirements and existing equipment.

Faster and More Efficient Post-Production

Using timecode significantly reduces the time required to synchronize video and audio recordings.

Modern editing software can automatically recognize matching timecode metadata, simplifying the entire editing process.

This workflow is fully compatible with professional applications such as:

• Adobe Premiere Pro;
• DaVinci Resolve;
• Final Cut Pro;
• Avid Media Composer.

Editors can quickly organize footage and synchronize recordings without relying solely on waveform matching or manual alignment.

Ideal for Multi-Camera Productions

When several cameras record the same scene simultaneously, manual synchronization can become time-consuming.

The Sony VMC-BNCU1 allows the Sony FX5 to become part of a professional multicamera workflow where every recording device shares the same timing reference.

This makes it particularly suitable for:

• concerts;
• live performances;
• conferences;
• sporting events;
• television productions;
• narrative filmmaking;
• commercial productions.

Designed Specifically for the Sony FX5

The Sony VMC-BNCU1 has been engineered specifically for the Sony FX5 Cinema Camera.
