The demo reel / Aurelia breakdown
How we built the AURELIA ad from one still
This is a full breakdown of one 10-second ad: the brief, the opening line, the stack, and the finished video. AURELIA is a fictional brand we invented; this is a self-initiated spec ad, not client work. Skincare is one of the most skeptical categories online, so we built a test, not a claim.
The finished ad. 10 seconds, 9:16, sound on. Every frame AI-generated. The “portfolio demo” watermark is ours — client deliveries ship clean.
The brief we wrote ourselves
- Product
- AURELIA, a fictional vitamin C face serum.
- Audience
- Skincare buyers who doubt before-and-after claims.
- Constraint
- Ten seconds, one mirror-selfie shot, no filmed footage.
- Format
- Mirror-selfie UGC · talking head
- Niche
- Skincare
The opening line
“One month, no filter, no foundation.”
The opening line is 'One month, no filter, no foundation.' In the first second it names what a skeptical skincare viewer is already checking for — filters and foundation covering the skin. It sets a testable frame the viewer can watch for, not a claim they would dismiss.
Why this format. Skincare trust is personal, so a single face talking to camera carries more weight than a product beauty shot. The mirror-selfie framing borrows the look of a real user review, which is the format this audience already believes.
How it was built
- 01
Hero still
One image, generated with Nano Banana Pro at 9:16. Framed like a phone photo rather than a product shot: the item in hand, the brand name legible on the label, light coming from somewhere plausible.
- 02
Motion and voice
That still becomes frame one. Seedance 2.0 takes it to ten seconds of 720p video and generates the audio in the same pass. Spoken lines are written into the prompt, so the delivery is lip-synced from the start instead of dubbed on afterwards.
- 03
Check before keep
Nothing survives because it looked fine as a thumbnail. We read the stream data with ffprobe, build a contact sheet of frames with ffmpeg, and compare the spoken audio against the script that was written. Takes that drift from the brief get regenerated, not patched.
- 04
Finish
The approved take is cut and packaged with ffmpeg for wherever it will run. Vertical for Reels and TikTok here; the same take can be reframed for feed or landscape if the brief asks.
What to watch for
The spoken line
The words are spoken by the person and lip-synced in the same render pass, not dubbed over the footage afterwards.
The bottle label
The serum bottle is framed close and the AURELIA name sits on the label, so the product reads without a graphic overlay.
The handheld framing
The shot is built as a mirror selfie with a slight handheld sway, the imperfection that makes a clip feel filmed rather than generated.
What this page is not
Every frame here is AI-generated, and AURELIA is a brand we invented for this demo. We claim no view or sales numbers, because this ad was never run as paid media. With a real product we'd shoot around the actual bottle and results.
We have no published reviews yet, so we are not going to borrow credibility we haven't earned. No client names, no engagement numbers, no invented case studies. What we can show you is the work and the method, in full, and let you judge whether it clears your bar.
