[Ignacio Triana] “I’m asking how come the clips (when put in timeline) aren’t readily playable using this selection in the easy setup?”
Because your clip doesn’t match your sequence settings. You’ll want to compare both of them.
If you selected the easy setup after you created your project, just create a new sequence. When you select a new easy setup, it doesn’t change the settings of already existing sequences, just the ones you create from there on.
