I wasn’t the cinematographer. I’m the director. I wanted my film to be on 4k because we had a low budget on production and I already owned a 4k camera. We thought we could crop and have more options for certain shots.
I scaled up to 120 on Premiere while editing.
The purpose: this is a short film, so its a narrative fiction.
But I don’t think you read the question right. I am looking to export in 1920×1080.
