wrong scale when emailing files
so I am working on a project with a coworker and he emailed me the rendered file. I downloaded and opened it in premiere pro. When I first starting looking at what he did I thought that he zoomed in on a lot of clips. However when we met up to work in-person the files were not zoomed in on his computer, only mine. We figured out to get our projects to match visually we had to take each file and edit the scale from 100 down to 50. Unfortunately, when I would email the file to him after my work, he had to edit his scales from 100 up to 150. Is this a problem on my end or his and how can it be fixed?
