Greeting everyone. This is my first post here. And I have what I'm sure is a noob question so please excuse for my lack of knowledge. I'm a photographer and I'm now starting to learn video.
Once I'm finished editing my video, how do I square it/change the aspect ratio so that when I upload it on my phone for Instagram it will fill the entire frame on Instagram without me having to use one of those cropping/square apps??? I want my videos to fill the entire frame on Instagram without me have to use a cropping app or me cutting out some of the video. Can someone help??????
*I'm using Adobe Premiere Pro*
