Yaw-drive slew rings: Seedance 1 Pro Fast I2V, 1080p, 62cr, no native audio
The yaw slew ring moves from a locked still on Seedance 1 Pro Fast, 5s or 10s, 1080p, 62cr, audio false; gearbox-ratio Qwen slides already shipped.

A yaw-drive listing a buyer can order is this slew ring: race, pinion, motor, the paint and bolt circle on the unit you ship. Motion is the ring turning on that still. Ratio is a board another page already lettered. Photograph the drive. Buy a silent orbit. Leave the Qwen slide where it is.
Photograph the slew ring
The honest plate is the drive you ship. Same frame, same pinion orientation, same motor jacket, same bolt circle a buyer will match to the drawing. Crop the rest of the nacelle if the nacelle is not the SKU. A paragraph will mint a prettier turbine with a different race.
Do not prompt a tech into the aisle because the plate “looks empty.” Empty is how a buyer reads the hardware. A generated torso fills the ring with a person who does not work for you, standing next to a cousin of the product. Dealers match geometry: race diameter, tooth count as it actually appears in the photo, the colour of this housing. Text-to-video of “a wind-turbine yaw drive slewing at golden hour” invents a cousin pinion and a tower you do not operate.
Keep grease tags and handwritten lots out of the catalog crop unless they belong on the line card. Do not prompt the model to “add a nacelle for scale.” Scale is a known bolt, a known motor length, a tape in the still you shot. Scale is not a replica tower.
Seedance 1 Pro Fast moves it silent
Seedance 1 Pro Fast is ByteDance image-to-video. It requires an image. Audio is off. Durations are 5s and 10s. Ceiling 1080p. Display price 62 credits. Fast is a speed flag, not a reason to skip the plate. The model only buys motion.
Lock the slew-ring still, then spend 62 credits on a 5-second hold or a 10-second slow orbit. Prompt the travel — locked camera, light graze across the race, the ring rotating, no new pinion, no new motor. Do not prompt a person onto the deck. Do not prompt the teeth to sprout a ratio the still does not show. Hardware the model invents is a different drive.
The launcher for a single still is AI image-to-video. Same job, different door: image in, clip out. Text-to-video of a nacelle yaw cycle invents the ring and invents a voice. Both fail an OEM check. Turn a photo into a video is the named one-still job: attach the catalog jpeg, describe the hold, pick an image-to-video model. Cost is priced per model, shown before you confirm.
Pick 5s when the still only needs a hold. Pick 10s when the orbit needs the extra seconds. Do not pick 10s to “find” a talking tech. Silent is the spec. audio is false. A slew-motor whine in the prompt will not become a stem. Prompting “voiceover: 1200:1 yaw” buys you a silent file with extra words the motion model may paint as type. Aspects on this row include 21:9, 16:9, 4:3, 1:1, 3:4, 9:16. Match aspect to the plate. A 9:16 still into a 16:9 generate is a crop the model will invent.
Gearbox-ratio Qwen slides already shipped
Gearbox ratios belong on a Qwen slide, not inside the prompt is the industrial-gearbox leftover: ratio, service factor, mounting, lettered on a Qwen board at 4 credits, 2K. That board is the catalog math. This leftover is not a second board. Do not re-prompt the ratio into a video paragraph so the housing “shows 1200:1 on the bell.” You will get cousin glyphs and a stage count the datasheet does not print.
Qwen Image 3 Text to Image already did that lettering job: 2K, 4 credits, complex text rendering. Do not twin it. A yaw slew ring is not a helical catalog slide with a ring drawn around it. The SKU is photographed iron and a silent orbit, not a second ratio string. Ratio lives on the slide. Motion lives on Seedance 1 Pro Fast from the ring you photographed.
Do not copy the gearbox slide onto this race — fake nameplate, invented service factor, seasonal “run this in a nacelle.” That house is the other listing. Pause on the ring. Same bolt circle in every frame. Rotation is the only thing that is allowed to travel. If the answer is a lettered slide, you made the gearbox twin. If the answer is a silent 5s or 10s of the drive you photograph, you made the yaw listing.
Overlay the ratio if the still stays clean
If the freeze-frame still needs a number, type it after picture lock. Do not ask Seedance to letter the ratio onto the race. Video models treat nameplate digits as texture. They garble 1200:1 into 12:1.
Add a text overlay burns one authored line for the whole clip — top, center, or bottom. That is the ratio, the bolt circle, a CTA. It does not transcribe. A mute slew ring has no speech to caption. Glyphs inside the Seedance pass are uneditable. Overlay after picture lock. Swap the string for the next SKU without regenerating the pinion.
Because audio is off, this clip is silent. Do not write a VO into the Seedance prompt and wait for a voice. Add voice later on a plate with no lips, or do not add voice. If a named applications person must speak, that person is real, on a different day. Generation still does the orbit. Keep lips off the race.
FAQ
Does Seedance 1 Pro Fast add a slew-motor soundtrack or a ratio VO?
No. Audio is off. You get a silent 5s or 10s file at up to 1080p for 62 credits. Lay sound after picture lock. Burn ratio as overlay, or leave it on the Qwen slide. Do not prompt a lecture and call it a mix.
Is this the same job as the gearbox-ratio Qwen slide?
No. Gearbox-ratio Qwen slides already shipped the math: 2K, 4 credits, lettered board. This leftover is the yaw slew ring in motion on a photographed still. Hold the ring. Do not regenerate the ratio.
Can I text-to-video a nacelle yaw and skip the drive photo?
You can. You will get a cousin pinion and a tower you did not photograph. OEM is the unit on the still. Seedance 1 Pro Fast still-to-motion from that still, via the image-to-video tool, is the hold.
Why not put 1200:1 in the video prompt so the housing typesets itself?
The motion model will invent glyphs and a ratio you cannot defend. Write the catalog string. Burn it with an overlay after picture lock, or keep it on the Qwen board that already exists.
