BATON LipSync – Automatic Audio-Video Sync Detection

Aurora is the automated, scalable file-based QC system that saves media providers time and money by driving efficiency, quality, and cost savings in their workflows. Aurora can be integrated with external workflow management tools in both on-premises and cloud deployments to continuously check, unattended, thousands of hours of content.

Poor quality sound is fatiguing and creates the risk of listeners tuning out. Like a dirty windshield, compromised audio quality obscures the sonic landscape. Details get lost, speech can be more difficult to comprehend, and content can suffer as a result. Omnia processing makes audio more listenable, less fatiguing, and more consistent. If you care about your Podcast content getting through to the listener, you need to care about sound quality.

As more audio is produced remotely and consumed on-demand, the challenge of consistent audio levels is becoming even greater. In fact, it is the number one complaint of podcast listeners!

OmniaTools™ allows you to automatically manage loudness levels on all content and create your signature sound on podcasts, helping you stand out and keep your audience engaged.

This easy-to-use, enterprise-class Windows Service makes it simple to create consistent loudness for all your audio files while improving the quality of the audio.

With scalable speeds from 3X to 50X, Etere QC is able to carry out high-speed controls of video files including that of black frames, audio silence and freeze frames.

Etere QC is an integrated file-based module for performing Quality Control (QC) via a streamlined workflow. It automatically detects and marks audio/video issues (e.g. freeze frames, black frames, scene changes, audio loss) on assets' EDL according to their quality, setting also a default quality rating at the end of the process.

Etere QC is able to speed up, automate and streamline the operational efficiency of file-based quality controls performed via workflow across the entire content life cycle.

Etere QC is the best solution for checking audio/video either prior (e.g. playout, repurpose, archiving) or after (e.g. encoding, ingest, editing, transcoding, archiving) media operations. It is able to check all the main videofile codecs and wrapper of any resolution including 4K.

BATON® LipSync is an automated tool for lip sync detection and verification. BATON LipSync leverages image processing and machine learning (ML) technology and deep neural networks to automatically detect audio and video sync errors. Using BATON LipSync, broadcasters and service providers can accurately detect audio lead and lag issues in media content in order to provide a superior quality of experience (QoE) to viewers.

BATON LipSync application is capable of performing facial detection, facial tracking, lip detection, lip activity detection, and speech identification. Sync errors can be debugged further in the BATON Media Player (BMP) through a feature-rich interface that plots out-of-sync audio and video errors on a skew timeline for better visualization. After errors are detected, BATON LipSync provides a comprehensive report of all the LipSync issues.

Available content can be checked in any language independent of the region and area. Offering support for most industry formats, BATON LipSync meets media professionals’ complex requirements for delivering high-quality multiscreen video. BATON LipSync can be seamlessly integrated into any existing content processing workflow, or it can be used as a stand-alone application.

BATON LipSync answers a critical industry need by replacing a time-consuming, expensive manual process with faster and more accurate machine-assisted detection.

With nearly a decade of developing AI and computer vision tools for the world’s number one interactive video platform at WIREWAX, and with another two decades of experience in the video and broadcast space, the team identified ways to leverage the platform’s award-winning image processing technologies in the big media sector too.

Lightning fast; face and object recognition, segmentation, fingerprinting, speech recognition and many other unparalleled tools available in the suite has changed the game for the broadcast and media industry.

Being able to scan entire archives of video assets and create a powerful, digital understanding of videos, programmes and movies with this core technology has enabled large TV and movie studios to leverage data and digital tools and services like never before.

We’ve not met a media business on the planet that doesn’t have a digitised asset problem. Lack of metadata, no understanding of content, zero monetisation capabilities and gigantic and disorganized archives. Not to mention expensive asset management, overpriced syndication and VOD preparation, and notoriously slow and extortionate manual services.

X-Pert Quality Check provides control analysis and assessment of media quality.

The application interface includes several subchapters. Thus, you may easily find what you need. Moreover, the customer needs are satisfied because of the quick and intuitive control provided.

Our software includes multiple quality tests:

• Loudness Measurements – ITU-R BS.1770-3, ATSC A/85, EBU R128.


• Color Frames Detection – particularly used to configure up to three colors for this test.


• Frozen Frame Detection – executes tests of the video stream in the content. Besides, you can get instant reports about the duration of the frozen frames.


• Correct duration – namely, compares file duration with the playout duration.

X-Pert Quality Check allows an automatic scan of many source directories. Furthermore, any of the predefined test presets can be related to any settled folder or subfolder.

The user-friendly interface includes an indicator of progress. In short, this is the result of the performed quality tests. Therefore, you will have files, which can be safely produced in X-Pert Playout.
