This term is used for digital video in general.
Artifacting is the result of compressing a video feed, causing
distortions and other visual inconsistencies. It varies depending on how
much compression is applied, such as broadcasting at lower bit rates,
and the way the source is compressed.
Some of the more overt signs of compression include blocky or overly
“soft” images. Older means of compression, seen on older DVDs or if you
are transferring content to DaCast that was compressed awhile ago, also
left a variety of signs resulting from digital transferring, including
ghosting, rainbow bands on finer details, and jagged edges.
