I am working w a video for fb that is 4:5.
I cannot stretch or change ratio because the video content area must stay the same.
There are black vertical bars on both sides of video which I want to change to white, so when posted on fb, it will look better.
I tried doing what Louie Clay suggested above but can't get it to work.
Video track 1 is original video.
Video track 2 is white blank clip.
Can the white blank clip replace the black bars???
