i just realised there’s an offset option in video player setup 
Video Player Setup
so any settings here plays the video earlier by that amount ? (can’t test it right now) if yes it’s exactly what i’m looking for.
by the way. when i import movies from any editor premiere or avid in h264 or DNx (both formats i use) the 2pop audio is always 1frame later then the video display. it became a routine to offset all audios i import from videos by 1 frame. yesterday i asked a guy in charge of calibration (not sure english term for that) for the movie i work on to confirm his 2pop video and audio are aligned and they are.
… why do i get that error in nuendo ? do you guys have this ?
