Ball-screw nuts travel in Kling silence; do not regenerate the lead
The nut walks the photographed screw in silent Kling; a redrawn lead is a different SKU, and a talking applications engineer is the wrong row.
The visual is the nut walking the photographed screw. Silent Kling. If the model redraws starts, you sold a different lead. No talking applications engineer.
A ball screw is a catalog cut: diameter, lead, starts, accuracy class, end machining. Buyers read those from the photo. Image-to-video is allowed to travel the nut. It is not allowed to reprint the thread. A talking millwright explaining preload is a different file and the wrong one.
Photograph the lead. Then move the nut.
Shoot the screw you stock: nut on the shaft, starts countable, end journal in frame if that is the SKU. Same light as the catalog. That still is the contract. Image-to-video starts there. The prompt is travel — nut walks toward camera, shaft locked, no new machining — not a paragraph that re-describes "precision ground 1605."
Re-describing the lead in the prompt is how the model argues with the pixels and mints a cousin thread. If the still already shows two starts, leave that alone. If the still is a muddy phone snap, reshoot. Ten seconds of a soft thread is a longer soft thread.
Turn a photo into a video is the named agent verb for this pass: one still in, a motion clip out. Cost is the row you pick, shown before dispatch. It is not a factory film and it is not a voiceover.
Silent Kling, two rows
Kling O1 Image to Video is the short silent hold: image required, audio empty, 3s through 10s, 56 credits. No max output resolution is listed on this slug — do not invent 1080p. 3s, 4s, and 5s are the honest tests. Identity drift likes the long end. Until the starts hold, stay short.
Kling V2.1 is the other silent I2V row on this job: 5s or 10s, 140 credits, discounted, audio empty, no listed resolution. Use it when O1's 3–10 band is not the hold you need and you still want Kling physics on the same plate. It is not a talking upgrade. Empty audio stays empty. 140 credits is not 56. Read the slug.
Neither row typesets a lead. Neither row should grow a plant VO. Prompt the nut, not the catalog sentence. If the generate redraws starts — two become one, a 5 mm lead becomes a 10, the journal grows a chamfer you do not machine — you sold a different screw. Throw it out. Do not "fix the class" in a second prompt on a drifted still. Reshoot or recrop, then animate again.
Because resolution is unspecified on both slugs, judge the output on the still you fed. A small plate is a small movie. Upscale the still first if the still is the problem.
The nut walks. The engineer does not talk.
A constructed applications engineer explaining critical speed, preload, or "what you should spec" is a mouth on a generate. This SKU does not need that mouth. The motion is the nut. Specs are overlay after lock, authored, the numbers you actually sell — not Kling glyphs.
Do not pick a native-audio cinematic row so the clip "sounds industrial." Silent Kling is the point. A hiss, a shop ambience, a VO about accuracy class, all belong after picture lock if they belong at all. A fake engineer is still a fake engineer with a disclaimer in the prompt.
If a buyer needs a human, film a named person. Generation can still do the travel. It cannot be the spec sheet.
Manufacturers and robotics are different /for pages
/for/manufacturers is plant-floor capability: line rate, QC, recruitment. That is a factory talking about a factory. This listing is one ball-screw SKU, nut on a locked shaft. Do not rewrite the manufacturer page as a catalog clip, and do not Omni a machine hall because "we also make these in-house."
/for/robotics-companies is the uncut demo: real speed, failures visible, integration. A ball screw in a robot cell is their object when the cell is the product. Here the product is the screw. Carriage-and-rail content is a cousin OEM job, not this nut. Stay on the photographed lead.
Text-to-video of "a CNC with ball screws" will invent a mill and a thread. That is a brochure of someone else's class. Upload the cut you sell.
FAQ
Can I prompt the lead ("5 mm, two start") instead of photographing it?
No. The still is the lead. A sentence will mint a cousin thread. Upload the catalog photo and describe only the nut travel.
Why O1 at 56 credits and V2.1 at 140 if both are silent Kling?
Different rows. O1 is 3–10s, 56 credits, image required, audio empty. V2.1 is 5s or 10s, 140 credits discounted, also I2V, also silent. Price follows the slug, not the brand name.
Does either Kling row add shop sound if I mention "industrial ambience"?
Not as a listed fact. audio is empty on both. Do not wait for a soundtrack. Score later if you need a bed.
Is this the manufacturer /for page with a tighter crop?
No. /for/manufacturers is plant capability and hiring. This page is nut travel on a locked screw still. OEM SKU versus factory audience. Keep them apart.
