random bars appear, green, gray, black in preview and export, Pp 2021
Hi
Im new to Pp, installed fresh version and tried first composition.
footage shot on gopro 1080p resolution. noticed that green bars but smaller in preview and was thinking that is preview or corrupted source issue.
after exporting found same and bigger randomly all over video. tried to change settings, codec, resolution - same, just other random places.
any ideas what can be here?
PC is not super video editor's - dell inspiron laptop with intel iris xe integrated card, last drivers
