Ciao Borate,
we are close to... really it doesn't matter the original file, I have a lot of clips filmed in 16:9, and I need to convert them in 9:16 for social networks. I mean I think do you know reels for example. You see them by your phone in vertical, and the video fill al the space in you screen, this is the result I want. And yes, of course in this way I cut the left and the right part of the original clips, is it clearer now?
Thank a lot and all the best
