I have a project that is comprised of video captured in portrait mode. I would like to fill the black bands (background) on the sides of the video with duplicates of my main video using premiere elements 14. Is this possible and if so how? I've attached an image to show what I'm going for.
On what computer operating system is your Premiere Elements 14 running.
What you describe can be looked at in concept as Split Screen effect. Please check out the following
which points to two videos, but it could be more than two displaying simultaneously.
Basically you will be stacking and positioning the video clips on Timeline video track 1, 2, 3 and sizing each to occupy 1/3 of the frame.
I will revisit your thread in the morning morning if you have questions about the concept to which I am pointing.
Any questions or need clarification on the above, please do not hesitate to ask.
