The thing that confuses me is that I recently worked on a few videos and nothing like this happened. I did everything the same way I am doing now, but I didn’t need to render along the way. I didn’t need to render at all, in fact. I’m working with 8GB of RAM and 70GB free on my hard drive. Any ideas?
Also, I have to render along the way because I am not able to add transitions unless all the files are rendered
