Dual Recording

Why It Exists

Content creators, vloggers, and users need to record reactions and scenes simultaneously without external equipment or multiple takes.

How It Works

Galaxy Dual Recording enables users to record video from both the front and rear cameras simultaneously, creating a split-screen or picture-in-picture effect. Galaxy AI enhances the recording by synchronizing audio from both sources, optimizing focus and exposure dynamically, and providing intelligent scene composition. The system handles motion stabilization, automatic framing adjustments, and audio mixing to produce professional-quality dual perspective video.

Everyday Use Cases

• Vlogging
• Reaction recording
• Tutorial creation
• Interview capture
• Event documentation
• Behind-the-scenes content

User Workflow

• User opens Dual Recording mode in the Camera app
• Both cameras activate simultaneously
• AI synchronizes audio and video streams
• System optimizes framing for both perspectives
• Video is recorded with real-time preview

AI Processing Flow

Audio and video from both cameras are captured and processed by the on-device NPU. Audio mixing uses AI to balance voice levels between front and rear microphones. Video synchronization eliminates drift between the two streams. Scene optimization adjusts exposure and focus for both cameras. Motion stabilization applies to each stream independently. All processing is real-time on the NPU.

Inputs / Outputs

Inputs:

• Front camera video
• Rear camera video
• Dual audio streams
• Motion sensor data
• Focus and exposure settings

Outputs:

• Synchronized dual video
• Mixed audio
• Motion-stabilized recording
• Optimized framing
• Picture-in-picture or split-screen output

Known Limitations

• Audio mixing may not perfectly balance voices
• Battery drain is higher than single camera
• Limited to supported Galaxy models
• Resolution may be reduced for dual stream

Unsupported Scenarios

• Multi-camera recording with 3+ cameras
• Live streaming dual recording
• Audio commentary addition
• Post-recording editing
• Teleprompter integration

Performance Notes
