“Do you mean that the assets will reorganize within the square frame to have the same look and feel as they were in the 16:9 frame? Or as Tero suggests you just need a crop?”
Steve, yes to your first question, I would like them to reorganize. I would have loved to have the expressions know how in order to whip it up the way you have outlined, but my use of expressions is unfortunately very basic, which is a bit naughty of me after all this time. Back to my Marcus Geduld book soon I think.
Andrew, your method was also suggested to me yesterday by someone else, I think this is what I will go with. Think there may still be a bit of adjusting but i can only foresee a few layers being affected.
Thank you for all your responses!
