To paste attributes, right-click on the reference event and choose Copy. Then right-click on the target event and choose ‘paste event attributes’. If you have multiple events selected, the attibutes will be applied to all.
Note that you cannot separate attributes, so if the reference event has filters or keyframes, for example, they will be applied as well.
To create a mask, open a paint program and make your bars on top and bottom with transparent in between. Save as a .png file. Then drop it in to a video track above the others and strech it across the whole project.
To use Pan/Crop, choose any of the widescreen presets in the preset dropdown. As I’ve pointed out, you can apply this to a whole project if you drop your veg (project) fle into another timeline.
