Description:

“Combing” is any interlacing artifact introduced to the content image. This is often the result of an incorrect frame rate conversion that does not fully remove interlaced frames.

Impact:

Combing is a very visible issue that is exacerbated by motion on-screen. This creates a very poor customer experience, as the eye is drawn to the object edges on screen and the viewer is removed from the story. 

Severity Structure:

FYI

On archival footage integrated into the program.

Issue

Motion is blurry and trails form alongside the opposite edges of motion.

How to Prevent:                          

Use a professional quality hardware or software standards conversion solution when changing from one frame rate to another. Avoid using a non-native frame rate source clip in a sequence of a different frame rate.

Solution:

Ensure that the native frame rate of the source material is being applied. Review the field order that has been flagged in the files header information. If there is a discrepancy you may need to re-transcode or deinterlace.
