In v19 specifying crop settings with numbers was introduced. I am very grateful for that! But what one can specify is rather the margin, i.e. X2=1200 for a 1280x720 production with a 80 pixel crop on the right margin. It would be more useful (as well as easier for the operator) to be ablo to specify using any of three methods:
- absolute (eg X1=128, X2=1152)
- relative (X1=128, X2=-128)
- percentage (eg X1=10%, X2=-10%)

Ideally the method used would be preserved in the preset. But perhaps that is impossible for some reasons (e.g. backwards compatibility).
