VidCheck, a specialist developer of software tools for broadcasters, will be launching at NAB the brand new VidChecker
software product - a new type of product which not only provides automated checking of file-based media but also intelligently automatically corrects
video and audio problems (including audio loudness).
VidChecker checks video parameters and using unique VidCheck developed algorithms* can intelligently correct problems such as incorrect levels in a way which is not visible to the eye, overcoming the problems of so-called 'legalisers' which simply crush over-limit values often introducing unacceptable degradation and artefacts into the video images.
The product also includes not only audio loudness checking based on ITU-R BS.1770, as recommended by the ATSC in their recently released Recommended Practice, but also user-selectable automatic correction of over-limit levels without impacting the perceived frequency range, quality or dynamic presence of the audio.
It is the perfect low cost solution to the proposed US Commercial Advertisement Loudness Mitigation (CALM) legislation which is on the way to becoming law. The CALM Act requires the FCC to adopt standards to ensure that all broadcast advertisements shall not be excessively noisy or strident, and not have an average maximum loudness substantially higher than that of the accompanying program.
"VidChecker is a significant new product in the broadcast business" said VidCheck founder, Thomas Dove, "the challenge of checking tens or hundreds of incoming commercial spots and hours of other content every day - and manually correcting levels using proc amps or other tools - is already a significant problem for broadcasters. The new CALM legislation will make this mandatory and having personnel manually checking everything before broadcast is not only time consuming and expensive, but in many cases not a viable option. VidChecker is a new approach which allows this to be built into the workflow and done automatically, at low cost."
VidChecker is a software product which runs on standard Windows PCs and can be used stand-alone or integrated with media servers and automation systems in broadcast workflows. It works with a wide variety of SD/HD video and audio standards.
The product, which is available as VidChecker Spot specifically for checking commercial advertisements and VidChecker Pro for longer program content, will be launched at VidCheck's booth N4019 at NAB 2010 in Las Vegas, April 12-15.
