I have a video which I want to place a blue background strip along the bottom throughout the video and add my text commentary and notes.
I have tried adding a mask but not got anywhere.
What I want to do is blank existing subtitle area and edit my own .srt file which can be optionally added later.
I just want to add a blank blue box along the bottom slice of the screen throughout the video.
I am a total newbie and need guidance.
Thank you in advance for any feedback.
