# markers

Point a coding agent at exact times and regions in a video. Open a video, drop
time markers and draw rectangular areas, reference them as `@alias:marker-1` /
`@area-1` in a prompt, and copy an expanded prompt with precise timecodes, frames,
and source-pixel rects to paste into your agent.
