We are using video lectures in one of our courses and we have added subtitles/captions but when we increase the screen size of the video to full screen, the subtitles start overlapping each other (see the images below). We reduced the overlapping by creating captions with only one line but it is still overlaps sometimes and not ideal when people speak fast.
It looks like when we play the video full screen the font size of the subtitles increases automatically. Can we change that? Is there something we can do?
I would appreciate any suggestions or experience you might want to share.
