I would be glad to help. Before I begin, I want to make sure what type of video editing you would like to do. Do you want to add black bars to the sides or top and bottom of the image that will stay the same throughout the whole video, or are you interested in blacking out a section of the video (like a persons face) that will change over time?
You're welcome! If you have any related questions in the future feel free to put "FOR DAVID" in the title if you want to request me directly. Have a nice day!
