Superseded: the video kit now does this with goose-studio's logo-equation-card style, which uses the html-frames part, version 1.2.1 (the card), the cut-footage part, version 1.2.1 (the timelapse b-roll) and the audio-mix part, version 1.1.0 (the optional bed), in the parts folder of this repository. This renderer stays, unchanged in behaviour, for goose-studio's create-logo-equation-card-video-ad molecule until it moves; its scripts still run.

render-logo-equation-card

A card-led format: everything the viewer reads is on a static black card in the top third; under it, b-roll moves like a timelapse to stop the scroll. One animated event: the CTA line hard-cuts in at 2.0s. No voice, no captions, no cuts.

Run

python render_card.py card.json --out-dir work/            # card-no-cta.png, card-with-cta.png
python compose.py --broll broll.mp4 --cards work/ --out ad.mp4 --in 3 --speed 4 [--bed bed.mp3]
python measure_motion.py ad.mp4 --cta-at 2.0              # exit 1 = reject
