A 30-second sequel: the same man — same mustache, same mustard cardigan — keeps getting better while the app keeps getting better. Narrated by Honey.
One file — the full commercial (TikTok-ready)
1080×1920 vertical, all five clips cover-cropped to 9:16, Honey voiceover baked in, and the real Human Brain App logo as the outro — one file to download. Runs in your browser (~45s).
Guaranteed TikTok-ready MP4 (one command)
No-fibs: the in-browser render above can't be guaranteed TikTok-valid — TikTok is picky about the exact MP4 container, and some browsers only record WebM. The bulletproof path is this one free ffmpeg command run locally with the assets below; it outputs a true 1080×1920, H.264 + AAC, faststart MP4 that uploads to TikTok cleanly. No ffmpeg? Use CapCut or TikTok's own editor: drop in the five clips, add the voiceover as the sound, place the logo as a 2-second endcard, then export.

No-fibs — what this commercial is
All five clips are AI-generated with the Real Life Video Lab's Veo engine (photorealism prompts, silent), and the voiceover is Honey TTS. "Gary" is the same fictional character as the 60-second mockumentary — described identically in every clip prompt (brown hair, brown mustache, tortoiseshell glasses, mustard-yellow cardigan) for the best continuity the engine allows, but AI generation cannot guarantee a pixel-identical face across clips, and these sequel clips were generated fresh, so Gary's exact face may differ slightly from the first commercial. There is no real promotion, no real workplace, and the events are staged comedy, not documentary footage. The "app keeps getting better" line refers to labs that actually ship on the platform — new labs are added and every lab's claims are labeled by verification status. A "30 second" commercial is five 6-second clips (30s) plus a ~2-second logo endcard because the lab caps each clip at 6 seconds. The "Render the full commercial" button stitches all five clips, cover-crops them to a true 1080×1920 vertical frame, bakes in the Honey voiceover, and ends on the real Human Brain App logo (the official emblem) as the outro — entirely in your browser (canvas + MediaRecorder). For TikTok: it outputs MP4 (H.264/AAC) when your browser supports recording MP4 (recent Chrome / Safari desktop do); if your browser can only record WebM, the badge above will say so. The voiceover only bakes in when the audio host allows cross-origin capture; if it can't, the file renders silent and the badge says so. The back-to-back player above always plays the full spot with the voiceover regardless. If the in-browser MP4 is rejected by TikTok, the ffmpeg recipe above produces a guaranteed TikTok-valid 1080×1920 H.264/AAC faststart MP4.
