Video Offset

I feel I asked this once before but I cant for the life of me find any occurrence of where I did, so here’s the question (which may be a repeat).

I’ve tried various combinations of; Video Start Offset, Timecode Start, etc. and all just start from the start of the attached video. What am I doing wrong?

Indeed, changing Video start offset is the thing to change, as described here:

The problem may be that you are entering the timecode burned into the video as the start offset in Dorico’s dialog, but unless the timecode burned into the video starts at 00:00:00:00, it won’t match up. You need to use the absolute offset into the video file, regardless of the shown timecode. If you need to skip the first 30 seconds of the video, set the start offset to 30 seconds.
