I would like to understand why in some cases -loop 1 is required before the input files, and in some cases it can be omitted.
-loop option is specific to the image sequence demuxer. Without it, a single image input is a video stream of 1 frame length.
You would apply loop when you need to keep alive an image sequence input at a timestamp beyond its natural length, usually a fade. With the tpad or loop filters, this can be done inside a filtergraph instead of at the demuxer level.
