i switched from Premiere Pro to Davinci and missing the feature "Set to frame size". I found several option to set it by clicking on the project settings or changing the inspector Retime and Scaling options.
But im looking for a shortcut to do this function.
The biggest mistake I made after switching from Premiere Pro was thinking that my previous experience meant I could just jump into a new NLE without difficulty.
Nope.
As a new user, your first course of action should be to complete some Resolve training. The Beginner's Guide and Advanced Editing are an excellent groundwork to get you moving smoothly.
