Wowza Clearcaster Pro

Reliable Hardware Encoding with Unmatched Cloud Control

Louis Y. Kwon

Senior System Engineer, NOVA,

When I first saw Clearcaster Pro, I thought it wasn't much different from traditional encoders. After simply requesting a demo and using it for a few days of testing, it provides a user-friendly UI and cloud-based Clearcaster Manager provides continuous monitoring to identify issues that may occur during live broadcasting. It was even better for an engineer like me. We will use 15 Clearcasters to provide OTT services in New Zealand, including live broadcasts.

Adaptive Network Encoding

Increase reliability with adaptive network encoding, which automatically decreases bitrate in adverse conditions.

Real-Time Health Monitoring

Identify issues quickly with detailed monitoring metrics, from encoder health through first-mile network conditions.

Cloud-based Management

Simplify your workflow with remote management, customizable encoding workflows, and user-permission control.

API Integrations

Create and streamline fully automated workflows with a centralized management API.

Adaptive Network Encoding

  • Enable the power of adaptive network encoding over RTMP to automatically recover from bandwidth issues.

  • Constantly monitor low-level network metrics and performance, while automatically decreasing video streaming bitrate in adverse network conditions, ensuring broadcasts maintain smooth, buffer-free playback for end users.

Real-Time Health Monitoring

  • Take the guesswork out of encoder delivery and issue-identification with 100-plus stream-health metrics collected in real time.

  • Use the live and archived broadcast health metrics to quickly identify issues and maintain an audit trail over all broadcasts.

Cloud-Based Workflow Management

  • Prevent configuration issues and streamline encoder setup and broadcast management by leveraging the power of the cloud to enable real-time encoder command and control.

  • Build custom configuration templates, create streamlined broadcast workflows and tailor the web-based UI controls to meet the unique needs of your broadcast team.

API Integrations

  • Create fully automated workflows using ClearCaster Pro's centralized management API.

  • Broadcasters can integrate workflow automation for their entire encoding stack while service providers can gain control over on-premise contribution encoders to increase reliability and better support their end users.

The Wowza Integration

  • Integrate ClearCaster Pro into your Wowza Streaming Cloud or Wowza Streaming Engine workflows for the highest-quality publishing from encoding to distribution.

  • Leverage end-to-end support from Wowza, including stream-health metrics and logging across your entire workflow.

  • Use trusted encoder presets fully integrated with Wowza Streaming Engine and Wowza Streaming Cloud.

  • Deliver over the first mile with our reliable, proprietary WOWZ™ protocol.
