AIMoCap vs Live Link Face

AIMoCap is a browser-based AI motion-capture platform that converts uploaded videos into 3D animation for animation and robot-motion workflows. In its web workspace, users upload a source video, trim the motion segment, choose a target, submit processing, then preview or download the result. It captures body and finger motion together and aims to preserve natural weight shifts while reducing visible foot sliding. Targets include Default, MMD, Mixamo, CC&iClone, Roblox R15, custom humanoid characters, and Unitree G1 robot output. Humanoid exports are FBX animation files; Unitree G1 exports Mujoco-oriented JSON motion data. Output frame rates are 24, 30, 60, and 120 fps. The asynchronous API uses bearer keys and supports batch jobs. A free plan is available; paid plans start at $9.90 per month. Custom robot uploads are planned for later.

Live Link Face captures facial performances and generates animation for MetaHuman characters in Unreal Engine. The iOS app supports real-time and processed animation and can capture raw video and depth data for the MetaHuman plugin. Epic describes the Android app as a beta for real-time MetaHuman facial animation. Animation streams over a network to Unreal Engine through the MetaHuman Live Link plugin; the phone and computer must be connected to a network. App settings include OSC connections for external controllers and devices. Android timecode can use the system clock, an NTP server, or a Tentacle Sync device for multi-device synchronization. Real-time Android animation is limited to certain Qualcomm chipsets, and Snapdragon 8s chipsets are unsupported; Android does not support capture for offline processing. Live Link Hub can download recorded media from Android and iOS devices and trigger recording on a connected phone. The app is free on iOS and Android. The App Store listing requires iOS 16 or later, while Epic’s workflow description specifies an iPhone 12 or later and a Windows 10/11 desktop PC.
