Glitch (media)

In television and video technology, a glitch [ glɪtʃ ] is a brief incorrect output of picture or sound content , similar to glitches in electronics.

These errors often occur when winding inside a film or when reinserting the film after a winding process if the required data cannot be buffered and reproduced quickly enough.

Glitches also arise when interpolating individual data components of the signal that have been falsified or left out during a copy or transfer process.

This has an effect in the picture through increased artifact formation or even the formation of blocks of different colors. With the sound, there may be disturbing distortions of the frequency or background noise.
