I made a launch ad for @grouped_news in an hour with Opus 5.5 and Remotion, and I never opened a video editor. I added the voiceover and music with ElevenLabs.
The ad is a React app. It imports my site's CSS tokens and fonts, so it uses the same design system as the site.
I didn't review it by watching renders. It rendered about 20 stills and tiled them into one contact sheet, so I could check a whole cut at a glance before rendering any video.
Captions are measured in the real font and shrink to fit the 9:16 safe zone, so nothing hides under TikTok's buttons. Every cut lands on a 120 BPM grid, which made the music easy to line up.
It's one codebase, so the 30s, 15s and 6s cuts in 16:9 and 9:16 are each a different list of scenes.
My part was saying what felt wrong.
