Thanks to everyone, Richard, this was a wedding so I can not re-shoot, Bouke, unfortunately the camera is moving of paning very frequently and most of the shots are wide so I can not use a mask in most of the cases, so I have to do something with the whole frame,
and Dave, actually a picture-in-picture was going to be one of my resources to disguise the bad focus but I can not do it the whole 2 hours (or more) video, 4 tapes were recorded using a low sharp camera preset by mistake
I saw on a web than some video editors have better sharpening filters than others, but this case is really bad, not just slight,
I bought an analog video corrector device with sharpening but it seems to look worst than digital sharpening (unacceptable, not even close), I’m really desperate !!
