Our unique edge lies in our AI-driven video compression technology. Our state-of-the-art Content-Adaptive Encoding (CAE) Intelligent Optimization technology integrates advanced machine learning, image processing, and image enhancement, all controlled by a quality assessment mechanism aligned with subjective standards. Our solution supports various applications, including premium VOD, live broadcast streaming, and ultra-low latency RTC.

Visionular’s Aurora encoders, developed by world-renowned video codec experts, excel in delivering exceptional visual quality at lower bitrates and faster encoding speeds. Benefits include:

  • Enhanced Visual Quality: Our encoders offer an improved perceptual visual experience with more detailed and aesthetically pleasing images.
  • Reduced Operational Costs: Expect over 50% bitrate savings leading to significant reductions in storage and CDN expenses.
  • Lower Cloud Encoding Costs: Our efficient encoders allow running multiple parallel jobs on a single machine, drastically cutting cloud encoding infrastructure costs.

Visionular offers advanced H.264/AVC, HEVC, and AV1 encoders tailored for diverse applications such as UGC, PGC, RTC, e-Learning, Sports Streaming, and Live Shopping. Our encoders are designed to outperform competitors and open-source alternatives, delivering 30-50% smaller video files, enhanced speeds, and superior video quality.

Open-source encoders require specialized technical knowledge for optimal configuration. At Visionular, our experts finely tune the Aurora encoders to meet your specific needs, simplifying the process for you.

Our encoders can be utilized in multiple ways:

  • SDKs: Ideal for those already using FFmpeg or GStreamer, our SDKs seamlessly integrate into your existing setup.
  • AuroraCloud: This comprehensive, fully-managed SaaS platform caters to all your encoding needs for VoD, Live, and RTC scenarios.

Aurora encoders support various rate control modes like VBR, CBR, CRF, and CRF+VBV. These modes cater to a broad spectrum of applications, prioritizing either strict bitrate control or video quality. If you’re unsure about the best mode for your needs, we’re here to help with personalized advice.

Our encoder pricing is based on a per-minute model, varying with the resolution of the video encoded. For instance, HD encoding is charged at double the rate of SD, and UHD at quadruple the SD rate.

In addition to standard JPG and PNG formats, we support advanced image coding standards like AVIF and HEIF. Visionular’s image encoders can achieve file size reductions of 30-50% compared to open-source options.

 AuroraImage redefines efficiency in image compression. Deploying AuroraImage in your workflow can result in a 30-50% reduction in image file sizes, leading to:

  • Substantial savings in storage costs.
  • Faster image loading times.
  • Increased user engagement on your platform.
  • Reduced churn, driving more sales and prolonged user interaction.

53% of visits are likely to be abandoned if pages take longer than 3 seconds to load (according to Google). And, large, slow-loading images are one of the biggest culprits of slow websites. 

  • E-commerce, sports, and UGC websites, laden with hefty images, often fall prey to slow loading times. 
  • Eliminate churn and abandonment with AuroraImage – the most advanced image compression software. 
  • With images compressed up to 50% more efficiently than competitors, you can expect enhanced engagement, swift-loading websites, and significantly reduced abandonment rates.

AuroraEnhancer (PseudoHDR, Upscaling, etc.)

 Beyond encoding, video processing involves vital preparatory steps. Visionular’s AI-driven image enhancement tools optimize source content intelligently before encoding. 

Our AI communicates with the encoder to consider any pre-encode enhancements, resulting in optimized video output. To explore our enhancement products, including Super Resolution, Image Quality Repair, Smart Tone Mapping, and Frame-Rate Conversion, visit our product pages.
