I don't want to crop them.

In the attached sample you can see the partly broken 1st line (missing
content at always same position) and 2 broken lines (irregularly
horizontally shifted), 5..8 lines from bottom.

How would it be possible, to consolidate them by copy/average from
adjacent lines?

With the extracted sample you can also see a bug in ffmpeg. The videos
SAR is 12:11, so the JPEGs x/y dpi should be 11/12 instead 12/11.
