It looks like a negative scratch and is totally vertical. Its position is 8% in from left. Two pixels wide bright. The sorrounding pixels left and right of the bright ones are slightly darker. I did not observe this when recording except once, when I then played back the sequence it looked fine. I assumed it was a temporary viewfinder problem. But now, when the job is done, the line is apparent in the following clips. First after changing drive, the line is gone. It is a mess and I now have to zoom in every clip, loosing composition. What has happened?
