Video Indexer adds support for animation and multilingual content

We made our award winning Azure Media Services Video Indexer generally available at IBC last year, and this year it’s getting even better. Video Indexer automatically extracts insights and metadata such as spoken words, faces, emotions, topics and brands from media files, without you needing to be a machine learning expert. Our latest announcements include previews for two highly requested and differentiated capabilities for animated character recognition and multilingual speech transcription, as well as several additions to existing models available today in Video Indexer.

Animated character recognition

Animated content or cartoons are one of the most popular content types, but standard AI vision models built for human faces do not work well with them, especially if the content has characters without human features. In this new preview solution, Video Indexer joins forces with Microsoft’s Azure Custom Vision service to provide a new set of models that automatically detect and group animated characters and allow customers to then tag and recognize them easily via integrated custom vision models. These models are integrated into a single pipeline, which allows anyone to use the service without any previous machine learning skills. The results are available through the no-code Video Indexer portal or the REST API for easy integration into your own applications.



We built these animated character models in collaboration with select customers who contributed real animated content for training and testing. The value of the new functionality is well articulated by Andy Gutteridge, Senior Director, Studio & Post-Production Technology at Viacom International Media Networks, which was one of the data contributors: «The addition of reliable AI-based animated detection will enable us to discover and catalogue character metadata from our content library quickly and efficiently. Most importantly, it will give our creative teams the power to find the content they want instantly, minimize time spent on media management and allow them to focus on the creative.»

Multilingual identification and transcription

Some media assets like news, current affairs, and interviews contain audio with speakers using different languages. Most existing speech-to-text capabilities require the audio recognition language to be specified in advance, which is an obstacle to transcribing multilingual videos. Our new automatic spoken language identification for multiple content feature leverages machine learning technology to identify the different languages used in a media asset. Once detected, each language segment undergoes an automatic transcription process in the language identified, and all segments are integrated back together into one transcription file consisting of multiple languages.

The resulting transcription is available both as part of Video Indexer JSON output and as closed-caption files. The output transcript is also integrated with Azure Search, allowing you to immediately search across videos for the different language segments. Furthermore, the multi-language transcription is available as part of the Video Indexer portal experience so you can view the transcript and identified language by time, or jump to the specific places in the video for each language and see the multi-language transcription as captions as a video is played. You can also translate the output back-and-forth into 54 different languages via the portal and API.

Additional updated and improved models

We are also adding new and improving existing models within Video Indexer, including:

Extraction of people and locations entities

We’ve extended our current brand detection capabilities to also incorporate well-known names and locations, such as the Eiffel Tower in Paris or Big Ben in London. When these appear in the generated transcript or on-screen via optical character recognition (OCR), a specific insight is created. With this new capability, you can review and search by all people, locations and brands that appeared in the video, along with their timeframes, description, and a link to our Bing search engine for more information.

 

Editorial shot detection model

This new feature adds a set of «tags» in the metadata attached to an individual shot in the insights JSON to represent its editorial type (such as wide shot, medium shot, close up, extreme close up, two shot, multiple people, outdoor and indoor, etc.). These shot-type characteristics come in handy when editing videos into clips and trailers as well as when searching for a specific style of shots for artistic purposes.

Expanded granularity of IPTC mapping

Our topic inferencing model determines the topic of videos based on transcription, optical character recognition (OCR), and detected celebrities even if the topic is not explicitly stated. We map these inferred topics to four different taxonomies: Wikipedia, Bing, IPTC, and IAB. With this enhancement, we now include level-2 IPTC taxonomy.

Tanking advantage of these enhancements is as easy as re-indexing your current Video Indexer library.

New live streaming functionality

We are also introducing two new live-streaming capabilities in preview to Azure Media Services.

Live transcription supercharges your live events with AI

Using Azure Media Services to stream a live event, you can now get an output stream that includes an automatically generated text track in addition to the video and audio content. This text track is created using AI-based live transcription of the audio of the contribution feed. Custom methods are applied before and after speech-to-text conversion in order to improve the end-user experience. The text track is packaged into IMSC1, TTML, or WebVTT, depending on whether you are delivering in DASH, HLS CMAF, or HLS TS.

Live linear encoding for 24/7 over-the-top (OTT) channels

Using our v3 APIs, you can create, manage, and stream live channels for OTT services and take advantage of all the other features of Azure Media Services like live to video on demand (VOD), packaging, and digital rights management (DRM).

To try these preview features, please visit the Azure Media Services Community page.

New packaging features

Support for audio description tracks

Broadcast content frequently has an audio track that contains verbal explanations of on-screen action in addition to the normal program audio. This makes programming more accessible for vision-impaired viewers, especially if the content is highly visual. The new audio description feature enables a customer to annotate one of the audio tracks to be the audio description (AD) track, which in turn can be used by players to make the AD track discoverable by viewers.

ID3 metadata insertion

In order to signal the insertion of advertisements or custom metadata events on a client player, broadcasters often make use of timed metadata embedded within the video. In addition to SCTE-35 signaling modes, we now also support ID3v2 or other custom schemas defined by an application developer for use by the client application.

Microsoft Azure partners demonstrate end-to-end solutions
