Sorry if my english is approximative. Hope you will understand.
I think to know that resolution and format of a project depend of the size of the first picture/video dropped on timeline.
The first photo that I put on my timeline is a 4/3 size with bad resolution and others pictures and videos after are in real better resolution and 16/9 size.
Is there a solution to change format/resolution on the project instead of to start again with a good resolution picture inserted in first?
I’ve got hundreds of objects in my project and it really boring to imagine that the only solution is to start again.
