5 use cases

  • Make a narrated explainer video, approving each stage

    Build a 30 s to 2 min explainer with Claude, reviewing the brief, script, frames and final before each next stage runs.

    View prompt
    Using the repo GTKottman/mortiflix-oss, set up the studio with `npm install` and `npm link`, then run `mortiflix new explainer` for the brief <your video topic>. Run `mortiflix run` and report the gate the session stops at. Verify that the output names a stage such as script or style frames and waits for your approval.

  • Run the video studio from inside Claude Code

    Install the Mortiflix plugin in Claude Code and let it guide you through setup, a brief and each review gate.

    View prompt
    In Claude Code, install the plugin from GTKottman/mortiflix-oss with `/plugin marketplace add GTKottman/mortiflix-oss` and `/plugin install mortiflix@mortiflix`, then run `/mortiflix demo`. Expected output is a completed placeholder walk-through of every gate. Verify that the guide asks you before installing anything and before starting paid work.

  • Make a vertical social short that works without sound

    Create a 45 s to 3 min vertical short with hook frames reviewed first, using the social-short pipeline.

    View prompt
    Using GTKottman/mortiflix-oss, create a social-short project for <your topic> with `mortiflix new social-short` (inferred command). Run `mortiflix run` and report the first gate. Verify that the first review is the hook frames and that the output is vertical.

  • Animate a logo sting in a few minutes

    Run the logo-sting pipeline to get a 3 to 8 s logo animation with one directions review and a final.

    View prompt
    Using the repo GTKottman/mortiflix-oss, create a logo-sting project for <brand name> with `mortiflix new logo-sting` (inferred command). Run `mortiflix run` and report the directions gate. Verify that the output has a directions review before the final.

  • Create an instrumental song from a genre and topic

    Use the song pipeline to get a researched genre, checked score, MIDI and mastered track you can review.

    View prompt
    Using GTKottman/mortiflix-oss, create a song project for the genre <genre> and the topic <topic> with `mortiflix new song` (inferred command). Run `mortiflix run` and report the blueprint gate. Verify that the output includes a blueprint review before the final track.
