video-still-animator — Ken-Burns fallback clip from a still

Produces a short MP4 from a single PNG/JPG using ffmpeg's zoompan filter, so a downstream merge step still has a clip for every shot when an upstream AI video generation step gets blocked.

Why this skill exists

seedance-2-prompt (and any platform-moderated video model) can refuse individual requests for reasons that have nothing to do with the prompt's narrative quality:

• input photo contains a recognisable real person face
• output audio gets flagged by the safety classifier
• the moderation model's similarity threshold drifts day to day
