I've been watching Supergirl for a while now, and something got me wondering. Why are there 10-second gaps between most scenes (not all)? I encountered the same thing years ago with No Ordinary Family, which was also produced by Greg Berlanti. At first I thought it was a Berlanti thing, but there are so many TV shows by him. So, what is the reason behind this?
I know what you're talking about here. I'm going to assume that you, like I, sometimes watch an MP4 file (or similar) that you have come by through a non-traditional DVR method. And that it's on these files where you're observing the long black gaps.
The long black gaps appear to occur at the time that the commercial breaks would have been inserted when the show was originally aired. I think the next question is, if the process or agent involved in creating the MP4 file had the intelligence to remove the commercials, then why didn't it also remove the weirdly long black silence?
