- People checking short videos for fleeting inserted images
- Worth noticing
- The page distinguishes a flash frame from an ordinary cut by checking whether it stands out from both neighboring frames.
Field notes
The page describes candidate scoring based on how much a frame differs from the frames immediately before and after it, with a sensitivity control for surfacing more candidates. It says compression can obscure an inserted image, and suggests raising sensitivity when nothing is detected. The stated three-minute limit keeps the tool focused on short-form video; its processing claims are not independently verified by the homepage extract.
