A free HyperFrames block for an 8-second specs or features moment. Five rows of label and value slide in from the left in sequence, each with an accent underline that sweeps across, in a light scheme for boards or a dark scheme with a scrim for footage. Rows, scheme, line width, position and timing are set in a small configuration in the HTML; the background is transparent.

About this Skill

You say

/mk-specs-list Make a specs checklist over our Vael Cerise photo: Leather "Cherry calf, hand-finished", Hardware "Solid brass clasp", Fits "A 14-inch laptop", Handles "Hand-stitched, 22 cm drop", Made "In small, numbered runs".

Specs persuade when they are easy to read. Specs Checklist lays out five label-and-value rows beside your product, one at a time, with a crisp underline under each, so materials, sizes or features land while the product stays on screen.

How it works

  1. Ask: tell your agent five short label-and-value pairs and whether the background is light or dark.
  2. Fill: it writes your copy and colours into the block's variables, keeping text close to the length the layout was made for.
  3. Render: it renders a draft with npx hyperframes render, checks a few frames and renders the final MP4.
  4. Reuse: the variables live in one small JSON file, so the next version is one more render.

Tips

  • Keep labels to one word and values to a few.
  • Use the light scheme over bright photos and the dark scheme with a scrim over dark footage.
  • 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.
  • Leave the right side of your shot free for the product.

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

Can I add more rows?

Yes. Rows are a list in the configuration; five or six fit comfortably.

Will it read over a busy photo?

Pick the scheme that contrasts with the background and raise the scrim if needed.

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, Vael.
