Nēbu HVAC - ad A/B

Variant A is finished in Danielle. Variant B is waiting on ElevenLabs quota.

Updated 30 Aug 2026, 17:2x · 1:1 · cut from your four source clips

Fixed since last version

The glitch at 3 seconds is gone

You were right. Your storytelling clip hard-cuts twice inside half a second there, so my shot caught a fragment trapped between two cuts and it read as a flash.

I replaced it with a continuous dolly from your 1920px 60fps clip that moves from the furnace onto the unit on the wall. It is cleaner, sharper, and it actually shows the HVAC connection, which the old shot never really did.

Nēbu is now said “NEE-boo”

Re-cut in all three places. The videos below are correct.

The two variants

Variant ADanielle v322.8s
“Still scenting one room at a time?”

Names what they already do and makes it look small. The answer is visibly yes.

Variant Bold voice24.1s
“Your house has a smell. You just can’t smell it anymore.”

Nose-blindness. Higher stop rate, but opens on a mild accusation.

A is Danielle on v3 Conversational, glitch fixed, “NEE-boo” correct. B has the same picture fixes but still carries the old Bella voice, because its hook needs a fresh render and the quota is at zero.

Voice options

You were right, and I know why

I built the first pass on eleven_multilingual_v2, which is ElevenLabs' older model. It reads evenly and flatly, which is exactly the “AI” quality you heard.

Your account has eleven v3 and eleven v3 conversational, which are much newer. Every option below is on those. They also read about 3 seconds faster across the same script, because they breathe and vary pace like a person instead of marching through it.

Start with Danielle or Matilda on v3 Conversational. Those are the two I would use.

v3 Conversational

Tuned for natural speech. My recommendation.

DanielleWarm, unhurried, 20.7s
MatildaAssured, a little lower, 21.2s
SarahReassuring, even, 21.0s
BellaSame voice as before, new model, 21.0s
JessicaBrighter, younger, 21.1s
LauraMost energetic, 18.9s
AliceBritish, 20.0s
EricMale, 19.4s

v3 standard

Slightly more performed. Worth hearing against the conversational cut.

Danielle19.9s
Matilda21.9s
Sarah21.0s

What is left

Variant B needs 29 ElevenLabs credits

I said 1,200 earlier, then 106. The API's own figure is 29. Both of my estimates were high, in the direction that made this sound like a bigger problem than it is.

B does not need a whole new voiceover. Everything from “Five minutes to install” onwards is already rendered in Danielle and reusable. The only thing missing is B's opening line plus the bridge into the body:

“Your house has a smell. You just can't smell it anymore. Nēbu mounts on your HVAC. One unit, every room.”

The API itself reports the cost as 29 credits (v3 bills differently from raw characters). Your account is at 0 of 131,000, so literally any top-up covers this thousands of times over.

The build is already staged. The moment there are credits, one command renders the line, times the captions off it, cuts the picture, and redeploys this page. Roughly two minutes, and I do not need to ask you anything.
