Thanks again for everyone’s replies on this .
Something else or note, which probably makes my issues with computer slowdown more obvious. I often work with multiple “layers” with some clips overlaying each other on the time line. So in some cases there may be the equivalent of two “story lines” with their own effects being rendered together.
Still, I noticed when I am rendering a file that is not as large as 1920 x 1280 my computer runs fine, but once I’m rendering at 1080 it slows down to almost unusable .
Does anything help this, like, for example, using an external drive for the project file ? What about proxy files ? I have always been a bit confused how that works as whenever I get into that my clips disappear.
Thank you again !!
