Many thanks to all for the replies.
My issue is that the data are from an old 8mm (1940) that I scanned.
Between bad filming, film shrinkage and less than acceptable frame
registration the zooming would be so significant that I'll throw away
most of the frames !!
I will play with the options and will come back to this one.
