Where the sample footage, pictures and music come from

The four sample Shorts on our home page were made by us on October 29 and 30, 2026. Every film clip and picture in them is in the public domain, under CC0 or CC BY, or was drawn by us; the clip credit is also shown inside the video while the clip plays. Every fact on screen was read on its source that day; the source is named in the video. The narrator voices are made with text to speech. The scary story is fiction.
