Competitive analysis and benchmarking

Compare your video solution against industry standards and top competitors. Identify strengths and weaknesses, and use the data to gain an advantage to boost your credibility and user base.

Audit

Find out how your video solution performs under different network conditions and across devices, and see how it compares to the competition.

Get brief insights into:

  • Your app's video and audio performance
  • How your app stacks against competition

Approach

Full and no-reference video analysis

Assess video quality using full and no-reference video quality metrics that can be adapted to the specific needs of your project and provide you with valuable insights. Improve video quality and improve your place in the market.

Full-reference evaluation

Learn about any visual distortions, artifacts, or quality losses across different conditions using full-reference quality metrics to compare videos against a reference baseline.

  • Analyze quality changes and degradation against the original reference
  • Precisely diagnose compression artifacts
  • Get insights into visual changes that may escape the human eye

No-reference evaluation

Gain insights about video quality when a reference video isn't available or when simulating real-world conditions using our custom testing environments and AI-powered algorithms.

  • Evaluate live streams and user generated content
  • Evaluate video quality in dynamic environments
  • Predict quality based on human perception
  • Identify quality issues affecting user experience
  • Conduct large-scale analysis of real user data

Industry-standard metrics

VMAF

A full-reference metric developed by Netflix.

SSIM

A metric used to measure the quality of a video or image by comparing its similarity to a reference.

PSNR

A video quality metric used to compare a degraded version to a reference or original version.

UVQ

A no-reference metric developed by Google.

BRISQUE

A no-reference metric that assesses image quality without needing a reference image.

Subjective MOS

A metric used to assess media quality based on human opinions.

Color analysis

A metric used to evaluate changes in video color hue, saturation and brightness.

Resolution (WebRTC)

Used to evaluate the clarity and detail in video and image quality by looking at the number of pixels.

FPS

Frames per second

Freezes

Statistics on length and frequency of freezes

Video Delay

End-to-end latency of video sent vs received

Network Simulation

Don't let changing network conditions affect viewing experience

Ensure your video delivers consistent quality, even under challenging real-world conditions. Our network simulation replicates the most common scenarios to help you identify and address video performance issues.

  • Bandwidth

    See how well your video adapts to bandwidth limitations. We simulate the speed and quality of the network to evaluate how well your video handles bandwidth changes.

  • Packet loss

    Make choppy playback and buffering a thing of the past. Find out how packet loss affects video quality during data transmission by simulating network instability and congestion.

  • Delay

    Understand how latency impacts video performance. By replicating data lag, we help you address issues like slow playback and response times to ensure smooth video streaming when speed is critical.

  • Jitter

    Reduce the impact of jitter on video quality. We help you detect video disruptions like stuttering, distorted playback, or audio desynchronization issues, ensuring your video streams consistently.

  • Disconnections

    Be prepared for network disconnections. By simulating different types of disconnections, we help you evaluate how hardware and software respond to disruptions and plan for swift recovery.

  • Congestions

    Learn how your video performs under heavy network load. Our network simulation provides you with data to ensure your video streams remain smooth and responsive, even during high-traffic periods.
