You'll have to show us the complete, uncut output of your ffmpeg command.

Also, which tool says it's 1088? Do you have mxfdump?

As far as I understand, MXF formats can have differing StoredHeight and
DisplayHeight, e.g. StoredHeight 1088, DisplayHeight 1080. (Not sure
whether that's what ffmpeg is doing.)
