LT-300 Capture Card Series
Flexible video capture platform for seamless integration
Multi-channel 4K video acquisition platform supporting standards from 4Kp60 down to 720p, with flexible SDI and HDMI input configurations. Designed for low-latency operation, the LT300 series enables raw acquisition, recording, real-time processing, compositing, and dynamic overlays. An integrated HDMI loop-through output provides live display with overlays applied, making it ideal for medical, industrial, avionic, extended-temperature, and high-end broadcast applications.
LT-311 4K/HD Capture Card
Four SDI inputs for simultaneous high-performance audio and video capture, recording, and frame grabbing, with automatic format detection.
LT-312 4K/HD Capture Card
Two HDMI inputs for simultaneous seamless audio and video capture, recording, and frame grabbing, with automatic format detection.
LT-313 4K/HD Capture Card
Two SDI and one HDMI input for simultaneous versatile audio and video capture, recording, and frame grabbing, with automatic format detection.Software & Integration
The LT-300 series is supported by a comprehensive software stack designed to simplify integration while offering advanced video and audio processing capabilities. From low-level access to raw video and audio streams to high-level features such as compositing, recording, and dynamic overlays, the Enciris software environment provides the flexibility required to build a wide range of professional capture and processing workflows.
Media Server
The LT-300 cards are managed through a dedicated Media Server, a central software component that handles all video and audio streams, along with their associated metadata. It provides access to raw frames in the desired format, as well as capture and recording capabilities.
By abstracting the complexity of the hardware, the Media Server exposes a unified interface to control acquisition, processing, and output. Users can integrate the video streams into their own applications, while the server takes care of stream management, synchronization, and recording.
Compositing
The Media Server can combine multiple incoming video streams into a single composited output, enabling multi-source views without additional hardware. This composited output can be used for live display, recording, or snapshot capture, providing a flexible foundation for a wide range of professional use cases.
HDMI Overlay
The platform includes built-in overlay capabilities that allow text, shapes, and images to be added directly onto video streams. With transparency control and dynamic updates, custom graphics or predefined templates can be integrated in real time.
Overlays are applied on the HDMI output, providing immediate visual feedback. Overlay content can be updated dynamically to display live labeling, status information, or on-screen cues in real time.
APIs & Frameworks
Enciris provides a RESTful API to control the Media Server and access all LT-300 features. To simplify integration, client libraries are available in C++, Go, and Python, allowing applications to interact with the server without dealing with low-level communication details.
Standard multimedia frameworks are also supported through DirectShow on Windows and V4L2 on Linux, making LT-300 cards easy to integrate into existing video pipelines and third-party applications.
