A 60-second mockumentary: one man — same mustache, same mustard cardigan — becomes suspiciously okay with The Human Brain App. Narrated by Honey.
One file — the full commercial (TikTok-ready)
1080×1920 vertical, all ten 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 (~90s).
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 ten clips, add the voiceover as the sound, place the logo as a 2-second endcard, then export.

No-fibs — what this commercial is
All ten clips are AI-generated with the Real Life Video Lab's Veo engine (photorealism prompts, silent), and the voiceover is Honey TTS. "Gary" is a fictional character generated by the model — the same man is 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 still cannot guarantee a pixel-identical face across clips. There is no real promotion, no real workplace, and the events in the mockumentary are staged comedy, not documentary footage. A "60 second" mockumentary is ten 6-second clips (60s) plus a ~2-second logo endcard because the lab caps each clip at 6 seconds. The "Render the full commercial" button stitches all ten 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.
