Hello , Could anyone tell me what exactly artefacts are . For example, I have this movie "Bad Boys II" (DVD-R) and sometimes I see some pixeles on the image like if it were a video stream on the internet, is that an artifact?
Thanks
and what about if the image freezes one second at the beginnig of every chapter , is that an artefact?
One more thing, if the subtitles have spelling errors , is that an artefact too? and what about if the subtitles are not synchronized with the image(they do not appear when they should ,they do it vey late).
Thanks
