Note: Vidchecker 8.2 supports the validation of Dolby Vision metadata, allowing you to ensure your HDR content is ready for consumption. SDR in HDR test will let you know how much of your content is using the full HDR dynamic range.

Other checks include RGB gamut, quality/blockiness, analog drops, digital drops, video stripes, corrupt frames, letterboxing/pillarboxing, black frames/sequence, color bars, freeze frames, layout checks, PSE flashing/ harmful patterns (Ofcom / ITU), video segment reporting, Dead Pixels, and Media Offline.

Audio Checks

Each track: audio codec, bit depth, sample rate, audio bitrate, number of channels, channel layout, channel mapping, tones, phase coherence between channels, track present during video, min levels, peak levels, clipping, clicks and pops, PPM, DialNorm, integrated/short term/momentary loudness (ITU/EBU/ATSC/ CALM/BS-1770), BLITS, GLITS & EBU test tone checks, digital silence. Supports 32-channel audio

Minimum System Requirements:

  • OS: Windows Server 2016, 2019 or Windows 10 (64-bit)
  • CPU: Recent single or dual Intel Xeon, with multiple cores and clock speed of >2.7Ghz. Vidchecker BASE is optimised to use all available cores, and POST is limited to using 8 cores max.
  • RAM: 32GB, or 64GB if UHD assets are to be processed.
  • HDD: Fast local HDD/SSD for installation, and additional SSD for cache if correction option is purchased.
  • Network: Fast connection to media location – 1Gbe minimum.

Tests Available

Video essence tests

Aurora video essence tests include Macro-block Noise, Up-conversion, Picture Quality (TekMOS, Perceptual Video Quality), Comb Artifacts, Field Order Swaps, Tape/Digital Hits, Perceptual & Film Artifacts, Black/Freeze Frames, Letterboxing/Pillarboxing, Dead Pixel Detection, Color Bars, PSE/ Flash Detection (Harding FPA), and Cadence Change.

Audio essence tests

Aurora audio essence tests include Silence, Drop-outs, Peaks (dBTP, PPM, dBFS), Average Levels (R128, ATSC, ARIB), Clipping, Snaps/Clicks/ Pops, Test Tones, Phase Swaps and Hiss/Hum. Aurora also applies a user-defined Audio Service Map for processing AES wrapped tracks or when mono channel audio essence tracks are tested together.

Metadata tests

Aurora metadata tests include Container Syntax, Video Essence Syntax, Caption Syntax, Container Essence Contents, Cross-Check Container- Essence, Rude Word Detection in Text, Start Time code, Time code Discontinuity, Video Resolution and Run-times. Additional metadata tests for Dolby Audio Syntax and Dolby E Guard Band Alignment are included with the optional Dolby codecs.

Scalable speed

Using high CPU allocation or a lower CPU allocation combined with Aurora’s unique GPU accelerated processing capability, QC throughput approaching wireline limits can be achieved, rather than being constrained by a legacy decoding, buffering and testing architecture.

QC report analytics

Aurora includes QC Analytics to enable media organizations to analyze results of multiple QC Reports and search across reports for specific criteria. Aurora can identify QC artifact trends and compare results from QC done at different workflow stages, pipeline issues and trends or identify vendors for KPI and SLA documentation.

4K production work flow

Aurora can test and play back the Interoperable Master Format (IMF), the distribution master format agreed on by major motion picture studios, and the supplemental IMF packages. Aurora has the ability to QC and play back complex Composition Play Lists (CPLs) and can test 4K at real-time or faster in any other container or codec, including JPEG 2000, DPX, DNxHR, HEVC, H.264/AVC/AVCI/XAVC. 1

Enhanced Adaptive Bit Rate (ABR) support

Aurora is the first file-based QC solution on the market capable of both testing and playing back HLS/HSS/HDS/DASH and CableLabs intermediate ABR playlist file sets. Aurora includes tests that have been specifically designed to catch the most common causes of adaptive bit rate streaming problems.
