When to use

Identify a speaker or a location in interview / documentary / podcast footage. Composite it over the video (set transparent: true, render with alpha) or use the built-in dark gradient for a stand-alone caption card.

How to adapt

name ≤ 24 characters keeps one line at 64px; longer names wrap.
align: "right" mirrors the whole layout for right-side framing.
holdSeconds controls how long the card stays before wiping out; the file is fixed at 5 s so cut the tail if you need it shorter.
Timeline: bar 0–0.5 s, box wipe 0.25–0.85 s, name 0.55–1.05 s, role 0.75–1.25 s, out from holdSeconds for 0.4 s.

Compositing

Render PNG frames with --default-background-color=00000000 (Chromium) or omitBackground: true (Playwright) when transparent is true, then ffmpeg -framerate 30 -i frame-%04d.png -c:v prores_ks -pix_fmt yuva444p10le lower-third.mov.

Do not change

window.motion, #stage size, animation-fill-mode: both.

Tudo nesta página também é legível por máquina. Aponte seu agente para o JSON ou adicione o servidor MCP do gimgs e peça para buscar templates de motion.

Baixe o JSON — contém o prompt, o schema de parâmetros e o código completo.
Preencha os parâmetros (comece por default_params) e codifique em base64url em ?p=.
Para cada quadro abra o player com ?t=<segundos>, aguarde data-motion-ready, capture no tamanho nativo e junte os PNGs com ffmpeg.

Prompt

Use the gimgs.net motion template "Lower third — slide bar".
Spec JSON (prompt + params schema + full HTML source): https://gimgs.net/motion/lower-third.json
Raw template: https://gimgs.net/motion/lower-third/template.html
Player for frame capture: https://gimgs.net/motion/lower-third/play?p=<base64url JSON params>&t=<seconds>  (1920x1080, 30 fps, 5s)

1. Read the JSON and follow its "prompt" section.
2. Fill the params (start from default_params) for: <describe what you want>.
3. Render: open the player at t = i/fps for i in 0..149 in headless Chromium (viewport 1920x1080, wait for document.documentElement.dataset.motionReady === "1"), screenshot each frame, then ffmpeg -framerate 30 -i frame-%04d.png -c:v libx264 -pix_fmt yuv420p out.mp4
4. If you need to change the design, edit the HTML but keep window.motion and #stage so the same renderer works.

Set params
name, role, accent; transparent=true for overlays.
Render with alpha
playwright: page.screenshot({ omitBackground: true }) per frame → ffmpeg -framerate 30 -i frame-%04d.png -c:v prores_ks -pix_fmt yuva444p10le out.mov
Composite
ffmpeg -i footage.mp4 -i out.mov -filter_complex overlay=0:0:enable='between(t,2,7)' final.mp4

param	type	default	description
`name`	string	`"Ada Lovelace"`	Big line (person, place or topic)
`role`	string	`"Founder, Analytical Engines"`	Small uppercase line in the accent colour
`accent`	string · color	`"#ffb224"`	Bar and role colour
`align`	string left \| right	`"left"`	Which side of the frame
`transparent`	boolean	`false`	true = transparent background for compositing over footage (render PNG frames with alpha, e.g. -c:v prores_ks -pix_fmt yuva444p10le or WebM VP9 with alpha)
`holdSeconds`	number	`3.6`	When the out-animation starts (seconds). The clip is always 5 s
