Tektronix Cerify is a file-based automated quality control platform that was a fixture in broadcast and post-production QC workflows for over a decade. It is no longer being sold by Tektronix as a new product (Tektronix Cerify datasheet). Existing Cerify installations continue to operate and Tektronix provides support and maintenance, but new customers evaluating file-based QC should assess current alternatives rather than Cerify as an active purchase.

This article documents Cerify's capabilities and market history for teams with existing installations, evaluators who encounter Cerify in legacy infrastructure, and buyers whose research surfaces it in QC roundups. Teams actively evaluating new QC platforms should also review the articles in this series on Pulsar, Vidchecker, and Interra Baton, all of which are actively developed and supported platforms.

What Cerify Was Built For

Cerify was designed as an enterprise-class automated QC platform for broadcasters, post-production facilities, and content aggregators processing large volumes of file-based content. Its architecture was scalable from a single-channel desktop installation to a multi-instance enterprise cluster, positioning it across the full spectrum from single-stream post facility use to high-throughput broadcast ingest operations (Tektronix Cerify datasheet).

Technical coverage: Cerify performed checks on encoding syntax, encoding parameters (bit rate, play time, aspect ratio, GOP structure, color space, frame size, frame rate), and baseband quality (signal levels, luma, chroma, gamut, black frames, freeze frames, field order, blockiness, audio silence, audio clipping, loudness and peak levels). The CeriTalk XML API enabled integration with automation and MAM systems, allowing workflow systems to receive QC results and make routing decisions automatically (Tektronix Cerify datasheet).

Template exchange: Cerify's XML-based test templates could be shared between Cerify systems and between content suppliers and broadcasters, enabling standardised QC specifications to be distributed as part of supply chain agreements. A broadcast network could send its delivery specification as a Cerify template to its content suppliers, ensuring both sides ran the same checks against the same criteria (Tektronix Cerify datasheet).

Cerify Developer Community: Tektronix built a partner ecosystem of over 50 companies with pre-built Cerify integrations covering MAM, workflow automation, transcoding, and playout systems. This interoperability layer was a significant institutional advantage — Cerify's presence in Digital Rapids Transcode Manager, SeaChange, Harmonic, and other broadcast infrastructure meant it could be adopted without custom integration work (Streaming Media QC roundup).

Cerify's Historical Pricing

At the time of its commercial activity, Cerify was priced from approximately $10,000 for a single-channel version and $18,000 for a two-channel version (Streaming Media QC roundup). Enterprise and multi-server configurations were custom quoted. These figures are historical references only: Cerify is no longer sold at any price tier as a new product. Reconditioned Cerify hardware may be available through Tektronix Encore, Tektronix's marketplace for reconditioned test equipment (Tektronix Cerify datasheet).

Cerify's Current Status

Tektronix's datasheet for Cerify now carries the explicit notice: 'The products on this datasheet are no longer being sold by Tektronix.' (Tektronix Cerify datasheet) Tektronix Encore is referenced for reconditioned equipment. Support and warranty status for existing installations can be checked through Tektronix's support portal.

Telestream, which has a longstanding relationship with Tektronix's QC product line, now actively develops Vidchecker as its current-generation file-based QC platform, and launched Qualify, a cloud-native QC solution integrated with Vantage workflows, in 2024 (Telestream Qualify). Teams running Cerify evaluating an upgrade or replacement path within the Telestream ecosystem should assess Vidchecker and Qualify as the current options.

For teams whose QC evaluation surfaces Cerify through legacy documentation or peer recommendation, the current-market platforms serving similar use cases are Pulsar (Venera Technologies), Vidchecker (Telestream), and Interra Baton (Interra Systems), each of which is covered in full articles in this series.

Cerify Reviews from When It Was Active

What Practitioners Reported

When Cerify was an active platform, it earned a reputation for thorough, standards-aligned checking and for its integration breadth through the Cerify Developer Community. Industry reviews and practitioner commentary from the period it was in active use reflect the platform's institutional position in broadcast workflows (Streaming Media QC roundup).

Strengths Noted at Time of Active Use

• The Tektronix alignment of testing algorithms meant Cerify's results matched tests from Tektronix's hardware test equipment, providing consistency between the QC software and the downstream broadcast chain.

• The Cerify Developer Community of 50+ integrated partners gave broadcasters a pre-tested integration path with the MAM, workflow, and transcoding systems already deployed in their facilities (Tektronix Cerify datasheet).

• XML template exchange between content suppliers and broadcasters was cited as a practical tool for reducing submission failures at the supply chain level.

Limitations Noted at Time of Active Use

• Single-channel base pricing at $10,000 was notable relative to alternatives that were emerging at lower price points. Streaming Media's review noted Pulsar Standard at $12,000 and Professional at $25,000 as comparators at the time, with Cerify's single-channel at $10,000 as the entry point (Streaming Media Pulsar review).

• Comparative quality analyses (PSNR, SSIM) were not available in Cerify as a stand-alone system, as it lacked access to the original pre-encode file for comparison.

• The browser-based interface, while accessible, received less positive usability feedback than competing platforms in practitioner comparisons.

Alternatives to Evaluate Instead

For teams actively sourcing a file-based QC platform, the three current-market alternatives covered in this series are:

• Pulsar (Venera Technologies): Windows-based, PPU and perpetual licensing, 6x faster than real-time for HD, pre-built Netflix/DPP/Amazon templates, IMF and HDR support. Pricing accessible to smaller facilities via PPU.

• Vidchecker (Telestream): Windows-based, Vidchecker-post (1 file) and Vidchecker-base (4 simultaneous), DPP PSE included, auto-correction, native Vantage integration. 15-day trial available.

• Interra Baton (Interra Systems): ML/AI-enabled, cloud/on-premise/hybrid, extensive audio/video checks including DPP/Netflix/iTunes templates, BATON Content Corrector, used by Turner Studios and Premiere Digital.

How Shade Works With QC Platforms

Regardless of which QC platform a facility uses, Shade provides the media library layer that holds content before and after validation. Files due for QC reside in Shade's cloud-native storage and are accessible to the QC system via the mounted drive. Approved content returns to Shade for delivery handoff or archive, with the full version history searchable through Shade's AI-powered search and the creative review stage handled through Shade's frame-accurate review workflows.

Final Assessment

Cerify occupied an important position in broadcast QC infrastructure for over a decade, and its template exchange model and Developer Community integrations influenced how the broader market thinks about supply chain QC. For teams with existing Cerify installations, those systems continue to provide value for the workflows they were built for. For teams actively evaluating QC platforms today, Cerify is not a current purchase option, and the evaluation should focus on Pulsar, Vidchecker, and Interra Baton — the three currently developed and supported platforms in this category.
