Automated Audio and Video Checking and Correction
Viewers expect consistent high quality video to be streamed to their televisions. However, digital displays and television signals use different color spaces, which means the video, must be tested to ensure the original colors and pictures are displayed on the screen. At IBC, Thomas Dove from VidCheck explained that automated video checking and correction can solve these issues by not only checking the files for video and audio parameters, but also correcting them. Black levels, color gamut and color problems (or, RGB levels) can be checked and corrected. In addition to video, audio peak levels (levels that are too high) and audio loudness (making sure audio levels are correct and legal) can be checked and intelligently corrected to avoid violations from the FCC.
