DaVinci Resolve 14 is your editor/coloring application of choice. What is the most efficient way of laying down keyframes?
You could use your cursor to find the correct frame within the keyframe timeline and right click, but that's straining on the hand. Instead, Command + [ for a dynamic keyframe or Command + ] for a static one.
Cmd + [ add dynamic keyframe
Cmd + ] add static keyframe
Not only does using keyboard shortcuts save you time but also makes your workflow more intuitive and creative. I dreaded keyframe work until I started using these commands, proceeding frame by frame using the left and right arrow keys.
After the keyframes are placed you can move between them using [ and ] without holding command. This feature really comes in handy when you want to compare the before and after result of a dynamic keyframe fade for example.
[ previous keyframe
] next keyframe
