Vidchecker QC Failure - RGB Gamut level

Because The Library QC is designed to assess broadcast-quality master files, it also has to make sure that files are broadcast safe. This means that the Vidchecker QC algorithm is checking a combination of elements including RGB/Gamut and Luma/Gamut. Excessive Chroma and Luma levels (i.e. if your video contains too high peaks between their colours/highlights) will fail the Vidchecker QC.

This article is designed to help you fix/alter these levels to ensure your video is Broadcast Safe and passes the Vidchecker QC. It uses screenshots and guides from Adobe Premiere and then Final Cut Pro, so if you are using different editing software to those, you may have to use different techniques than we would recommend.

The term "RGB gamut level limit" usually describes the range of colors that a certain RGB color space can show, often expressed as numerical values for red, green, and blue components.

Chrominance refers to the color range of the video. If the color range is too broad, TV screens may not display the image accurately, causing distortion.

The solution may be to re-export the file from the Edit Suite with a Color Filter or Limiter applied to the timeline or during export.
