Cropping in iMovie

[cheddar-caveman]

I have taken 500+ .jpg photos from a tripod mounted camera, to create a Time Lapse movie.
I have imported them into iMovie and then into the timeline.
I want to fill each frame with the subject so I need to crop every photo but I can only work out how to crop individual ones.
Is there a command somewhere that I'm missing to accomplish this?

iMovie version 10.1.10 2018

Does iMove have a save effect function like FCPX? If so, do your crop (is an effect) save it. Then select all the other clips and apply the saved effect (double click on the effect in the effect pane).

'Fraid not, it's fairly basic! I have tried in Lightroom 5 but that doesn't have the "actions" function either. Tried several downloads of batch crop editors but no luck there either!! I think later versions of Photoshop and the like have it but not prepared to buy such a thing just as an experiment!
