Bristol, UK – Vidcheck, a producer of advanced applications to check and correct file-based video and audio content, announced Version 7 of Vidchecker.
Vidchecker V.7 will be available as a free upgrade to existing customers possessing current Vidcheck software maintenance contracts, and to Vidcheck OnDemand license holders. Vidchecker V.7 will be introduced at the 2016 NAB Show in Las Vegas, April 18-21, where Vidcheck will be exhibiting on Booth SL5625.
Also making their world-first appearance are new automated correction options for Vidchecker. These give customers the ability to add a wide range of file-correction capabilities into Vidchecker or Vidchecker-post rather than having to select an entirely separate application.
New in Vidchecker V.7 are:
Automatic video segment detection. This identifies and reports back as timecode the start and duration of any segments bordered by black positionals. These are routinely placed in media files to accommodate commercials relevant to specific viewer categories
Advanced validation of Interoperable Master Format (IMF) metadata and essence. IMF files carry a relatively large amount of metadata to support multi-language, multi-reel, subtitles/closed-captions, video inserts and after-the-fact delivery of content with ‘supplemental packages’. IMF also includes metadata relating to audio and timed text essence formats, basic descriptive metadata, complex playlists, and delivery. A typical application will specify video codecs plus image characteristics and can specify additional descriptive metadata, for instance. Vidchecker V.7 is designed to check all this data and draw attention to any potential operational issues.
Multi-lingual alerts. Vidcheck users can now access quality-control alerts in practically any language rather than being restricted to English. Languages can be assigned within quality-control templates.
Peak attenuation. Adding to the loudness level normalisation of earlier Vidchecker iterations, Vidchecker V.7 incorporates a new audio correction algorithm which provides transparent adjustment of abnormally high audio peaks.
“Most of the V.7 feature set will also be available on Vidchecker-post,” Howard Twine adds. “The key difference is that Vidchecker is the faster of the two applications, capable of testing and correcting multiple files simultaneously.”
Designed for checking file-based video, audio and related metadata before and after distribution, Vidchecker is also used by broadcasters for checking files received from post-production companies and content owners to ensure that file, video and audio parameters and levels are correct and ready for general transmission.
Vidchecker provides a server-based alternative to checking conformance by eye and hand. It can also automatically and correct video and audio levels. Sub-SD, SD, HD, UHD, 4K, 8K and mixed workflows are supported. The Vidchecker GUI is accessed through a web browser either on the local machine or remotely over a network.
Vidchecker-post is full-featured version of Vidchecker designed for low-volume users such as post-production houses, content distributors and smaller broadcasters who do not have the file-testing throughput requirements of larger companies. Like Vidchecker, it is easy to install and use, performing thorough checks of video and audio parameters, and checking video and audio quality. It intelligently corrects video luma, chroma and RGB component, and conforms audio peak and audio loudness levels to ATSC/CALM and EBU requirements.
