Hello all, I am brand new to Mac with a Macbook Air. I have managed to fumble through and edit one of my wildlife videos. There is one question and a couple of related items that I have not found an anwer to. Finishing a Project - This renders in 4 different formats for me, 1080, 720, large, and medium. I understand that the different formats are for different applications, but I don't need all four versions for every video. Is there a way to either choose a format or delete the ones not being used. Thanks much.
