Picture in Picture Video with FFMPeg

Picture in Picture Video with FFMPeg

Creating a video with a smaller thumbnail video inside is known as a picture in picture effect. I’ve used other video editors in the past to merge various camera views together to give a more complete experience. In this post I’ll cover how to use FFMpeg to do the same thing.

In this post I’ll give some examples of the unsharpen mask. I won’t go into the details or mechanics of how the filter works. This will merely be a quick how to. I’m going to be working with a 30 second clip of video that was shot during the 2012 STP bicycle classic. It was…
