What it does

Once installed, the agent knows how to use the KrillinAI command-line tool to convert a regular landscape video into a vertical (portrait) format suited to short-video apps. It can burn in short bilingual subtitles, add titles, render dubbed versions, and run basic checks such as extracting a preview frame and confirming the output reports success. It relies on an existing KrillinAI CLI setup rather than doing the video work itself.

Great for

  • Creators who already use KrillinAI and want to turn finished videos into vertical clips
  • Marketers producing bilingual short-form video from existing footage
  • Developers automating vertical video rendering in a KrillinAI pipeline

Skip it if

  • People without KrillinAI CLI installed, since the skill depends on it and on a separate CLI reference file that is not included here
  • Anyone expecting a general video editor; it only drives the render-vertical command and cannot edit footage freely

Try asking

  • “Convert this landscape video to a vertical bilingual short with the title 'Today's topic'”
  • “Render a dubbed vertical version of my TTS-processed video using the target-language subtitles”
  • “Check whether the vertical subtitles in my last render are readable and not garbled”
  • “Extract a preview frame from the vertical bilingual video to review the layout”

Get better results

  • Read the referenced CLI contract first so the binary path, working directory, and environment variables (KRILLINAI_CLI, KRILLINAI_CWD, WORKDIR) are set correctly
  • Review the generated subtitle and preview output before publishing, since long Chinese lines are split across multiple timed entries
  • Confirm the terminal output includes "ok": true before treating a render as successful
