+### **WARNING ON PREMATURE EXIT**
+
+In order for the saved MPEG video file to be decoded and read properly in the future,
+the container must include a *moov atom* that acts as a sort of table of contents. 
+This is generally added at the end of the file, so exiting an active stream
+prematurely can result in an incomplete container. This can be remedied by
+copying the atom from a video with similar structure. This can be achieved
+using a library called `untrunc`:
+
+```bash
+sudo snap install --edge untrunc-anthwlock
+untrunc-anthwlock -s GOOD_VIDEO BROKEN_VIDEO
