/WHY
A title slide sets the tone for a whole talk. A moving ASCII scene behind it says technical and considered before you say a word, and works in every slides app.
The builder shows your title on the slide, gives you a 1920 by 1080 video for Keynote, PowerPoint and Google Slides with step by step instructions for looping it, a still PNG title slide, and the live link for web decks such as reveal.js, Slidev, Pitch and Canva.
/EXAMPLES
Each one is complete. Copy it as it is, or change the piece name to any piece in the library.

/GUIDE
Slides apps play video smoothly and loop it; GIFs are heavy and often stutter. The builder records an MP4 (or WebM where MP4 is not available) at 1920 by 1080, a few megabytes for 8 seconds.
The video works with no internet. The live link needs a connection, so for conference talks prefer the video and keep the link for web decks you present from your own laptop.
