Noise reduction, without reducing crispness, especially effective With most videos, I saw no adverse effects and the advantages Visible, it mainly affects material with already low quality. Moving objects, that stick in place for several seconds. This filter sometimes leaves faint color traces behind Next comes the Chroma noise filter, whichĮliminates color flicker that can be very intense especially withĭark, saturated colours.
