About this Skill
You say
/yt-lower-third Make a subscribe lower third for Ember & Bun (212K subscribers) with the Double Stack as avatar, over our burger shot.
The subscribe ask works best in the middle of a good moment, not after the video ends. Subscribe Lower Third gives you a clean, familiar YouTube-style pop-up with your channel avatar and a satisfying tap, laid over your footage.
How it works
- Ask: tell your agent your channel name, subscriber count and a square avatar, plus the shot it sits over.
- Fill: it writes your copy and colours into the block's variables, keeping text close to the length the layout was made for.
- Render: it renders a draft with
npx hyperframes render, checks a few frames and renders the final MP4. - Reuse: the variables live in one small JSON file, so the next version is one more render.
Tips
- Place it after a strong moment, not in the first seconds.
- Use the same avatar as your channel.
- The background is transparent, so render it with an alpha channel and lay it over your own footage, photo or a plain colour; the SKILL.md shows the two commands.
- It has no variables: your agent edits the text and numbers directly in the HTML, following the SKILL.md.
Open source
This is a block from the HyperFrames registry, made by HeyGen and the HyperFrames contributors (heygen-com/hyperframes) and shared under the Apache License 2.0. The download is the block with its assets and a SKILL.md written by Reelity, so your agent knows how to fill and render it; HyperFrames itself runs from npm.

FAQ
Does it show the YouTube logo?
No. It uses the familiar layout and a red button with your own avatar and name.
Can I change the button text?
Yes. "Subscribe" and "Subscribed" are plain text in the HTML.
Why is it free?
It is an open-source HyperFrames block by HeyGen and the HyperFrames contributors. We list it as it is, with a SKILL.md so your agent can use it and a sample made with one of our house brands, Ember & Bun.
