i-Pairs Inc. has launched a “Next-Generation Virtual Live Production Service” specializing in the production and technical support of projection-based live events using 3D character models, starting July 2, 2026. The service provides one-stop support from video production to stage setup and live operations, built on optical motion capture technology and proprietary in-house tools.

Service Overview and Technical Foundation

The service is built on the optical motion capture system “OptiTrack” and i-Pairs’ proprietary retargeting technology “n-Links Retarget.” Motion data captured through optical motion capture is applied to 3D character models in real time through skeletal optimization, enabling live productions featuring 1 to 10 simultaneous performers.

Additionally, the service leverages virtual production technology to composite CG character footage with live-action backgrounds in real time. Using a video switcher for integrated output, the system supports real-time compositing and streaming of live footage featuring both CG characters and real performers together on stage.

Service Offerings

The “Next-Generation Virtual Live Production Service” covers a wide range of production and operations support.

Beyond content creation such as video production, audio and BGM production, and 3D character model creation, the service also handles motion capture-based 3D character motion production and real-time streaming support. For virtual live events, comprehensive support is available ranging from stage setup and video/audio operations to multi-person simultaneous retargeting in mixed optical “OptiTrack” and inertial “Xsens” environments, transparent screen installation, band arrangements, and performer coordination.

Pricing follows a custom quote model based on the scope of work requested, and clients can choose to use only the services they need.

Future Developments with Yamaha’s “GPAP” Integration

i-Pairs is developing technology in partnership with Yamaha Corporation’s “GPAP” that will enable unified management of motion, audio, lighting, and laser effects within a DAW environment. Once realized, this technology would allow flexible modifications to costumes and motion after a main performance, enabling re-performances both domestically and internationally.

The company aims to create a “circular production workflow” that eliminates the need for post-editing or re-recording, a notable initiative that could significantly improve the production efficiency and scalability of virtual live events.

About i-Pairs

i-Pairs is a “digital content-specialized creative company” that handles diverse content production including music, audio, video, virtual production, and 3DCG. Through proprietary technologies such as their in-house software “n-Links,” the company has achieved greater efficiency and stability in live production. i-Pairs is an equity-method affiliate of Yamaha Corporation.

Commentary

Producing 3D virtual live events has been a high-barrier endeavor for individuals and small-to-mid-sized businesses due to the advanced technology required for motion capture and video compositing. i-Pairs’ service stands out for its comprehensive coverage of these technical challenges. The circular production workflow being developed with Yamaha is particularly noteworthy, as it opens the possibility of leveraging a single live production across multiple performances — a development that could greatly benefit VTubers and virtual artists looking to scale their live activities.
