What it does

Once installed, the agent can edit screen recordings (demo videos, tutorials, product walkthroughs) through a command-line tool called cli-anything-openscreen instead of a graphical editor. It can add zoom effects on chosen moments, speed up idle parts, cut sections, crop the frame, add text overlays, set backgrounds and padding, and render a final MP4 or GIF. It can also produce preview bundles (short clip, frames, summary) so it can check its own edits.

Great for

  • Creators who want to turn raw screen captures into polished demo videos with automated steps
  • Developers or power users who script video edits and want an agent to drive the tool
  • Marketers producing many similar product walkthroughs from a template-like workflow

Skip it if

  • People who want a visual, drag-and-drop editor; this is entirely command-line based
  • Anyone without ffmpeg and Python 3.10+ available, since the tool will not run without them
  • Recordings that must stay confidential: the files only describe local editing, but the agent will read and write video files on your machine, so review what it accesses

Try asking

  • “Create a new Openscreen project from recording.mp4 and add a 2x zoom on the login step between 4000 and 7000 ms”
  • “Trim the first 3 seconds and the last 5 seconds of my demo, then speed up the idle section from 10s to 25s to 2x”
  • “Add a text annotation saying 'Step 2: Click Export' at the top-left of the frame and render an MP4 at good quality”
  • “Generate a quick preview bundle, check the zoom and timing, then render the final video and confirm the output file exists”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Always ask the agent to use --json output and absolute file paths so results are reliable to parse
  • Remember times are in milliseconds and coordinates are normalized 0-1; check the values before rendering
  • Review the preview bundle before a full export to catch zoom or timing mistakes cheaply
