VC-1K: A Diverse Video Test Set for Real-Time Communication
We introduce Video Conferencing 1000 (VC-1K), an open-source test set comprising approximately 1,000 video sequences specifically designed for evaluating video processing and encoding pipelines in real-time communication (RTC) scenarios. Unlike existing test sets that primarily rely on studio-produced or screen content, VC-1K consists of user-generated video call content captured on consumer mobile devices under a wide variety of conditions. The dataset predominantly features talking-head sequences with distinct faces, but also includes a small subset of outward-facing, rear-camera videos without faces to reflect additional common RTC use cases. It spans a wide range of real-world variables including device type, lighting conditions, motion levels, indoor/outdoor environments, and demographic diversity. All video sequences are accompanied by synchronous audio to facilitate multimodal research. We detail the dataset's design methodology and statistical distribution, and demonstrate its
