Increasing file-based broadcast QA

On show at IBC is the latest Vidchecker V.7 software, designed for checking and repairing file-based video, audio and related metadata before and after distribution.

The new version offers automatic correction of luminance flashes known to cause problems for people prone to photosensitive epilepsy.

Other features include automated error correction, automatic video segment detection, advanced validation of IMF metadata and essence, multilingual alerts, transparent attenuation of audio peaks and transcoding to a pre-defined in-house file format regardless of input format.

Vidchecker is also used by broadcasters to ensure that the metadata, video and audio parameters and levels of media files received from post production companies and content owners are correct for general transmission.

The utility provides a server-based alternative to checking conformance by eye and hand.

It can automatically and intelligently correct video and audio levels, including peak audio attenuation, and perform automatic video segment detection. Sub-SD, SD, HD, UHD, 4K, 8K and mixed workflows are supported.
