Sprocket pitch is stamped in Ideogram on the hub, not generated teeth

Tooth count and pitch live as letters on the hub. Ideogram owns that type. A video model that redraws teeth sold a different chain match.

A sprocket listing is a hub stamp: pitch, tooth count, bore, the series already in the catalog. The teeth are a profile you already cut. A video model that grows an extra tooth, fattens a pitch, or melts 40B18 into decorative numerals sold a different chain. Type-lock the hub. Do not generate a cousin profile and hope purchasing does not notice.

Pitch is type, not a generated tooth

The chain match is a number. ANSI pitch, tooth count, bore diameter — those strings are why a buyer opens the PDF. They are not "sprocket-shaped" decoration around a pretty gear. If the still cannot be read, the motion is a commercial for a part you do not stock.

Photograph the hub square-on when you have the part. Light the stamp. Do not start with a spinning flywheel shot and hope the letters appear in motion. Motion will interpolate teeth. Interpolated teeth are a different pitch. The person who orders by count will count them.

Manufacturers is a nearby factory audience. That page is plant-floor proof and a general OEM loop. This page is the hub. A manufacturer playbook that I2Vs a generic gear and captions it as this SKU has used the wrong still. Bike shops is a different nearby audience again: a retail floor, a cassette on a wheel, a weekend rider. An industrial sprocket OEM who copies that playbook ships a bicycle part. Keep the hub large. Keep the stamp large. Crop the mill aisle before you buy seconds.

Do not generate a technician holding the part and quoting a ratio. The object is the hub. A talking ratio is a spec slide or a real named engineer, not a mouth on a generated face.

Ideogram stamps the hub

Ideogram V4 is the text-to-image row for the stamp: 6 credits, accurate letter rendering, pack-shot and poster work, 1:1 / 16:9 / 9:16 / 4:3 / 3:4. It is an image model. It does not spin. It does not invent a chain line as a soundtrack. That is the compliment.

Generate an image from text is the named still job. Prompt the lockup you would laser: series, pitch, tooth count, bore, material callout if the catalog shows it. Ask for a square-on hub, sharp stamp, teeth that match the count you named, no extra badges. Approve at 100% zoom. Count the teeth. Read the pitch. If either is wrong, you are still on an image meter. That is the cheap place to fail.

A video row that "also does text" will move the part and renegotiate the stamp. One extra tooth is a different SKU. A 40-pitch that becomes a 41-shaped scribble is a different chain. Recraft can letter too; this page is Ideogram because the hub is a stamped plate, and stamped plates are posters with a part number on them.

If you already have a photograph of the finished hub, skip the generate. Crop it. Straighten it. That file is the stamp. Ideogram is for when the photo does not exist, the existing photo's letters are unreadable, or you need a clean hero of a SKU that is still in tooling. It is not a style filter you run on a good part photo for luck. Do not "enhance" a real stamp into prettier type. Prettier type is a different part number.

Product video after the letters lock

Once the hub would survive a freeze-frame, the AI product video generator is allowed to do a short, boring thing: a slow orbit, a hold on the stamp, a slight turn that does not grow teeth. Prompt camera and physics. Do not re-describe pitch in the video prompt. Re-describing is how the model starts cutting a second profile.

Keep the clip short enough that the count cannot crawl. A long "industrial motion" piece will spend the video meter on sparks and chain and a cousin tooth. If you need chain motion, that is a different still — a photographed strand — and a different generate. Do not ask one pass to stamp the hub and articulate a chain. The stamp will lose.

If the feed is mute, burn pitch and count as overlay on the locked motion. Overlay is type you wrote. It is not a substitute for a readable stamp in the plate, and it is not permission to let the model restamp the hub. Legal and purchasing will look at the metal, not the caption.

Reference-to-video off photographs of the real part is the honest path when the pad or the bench changes and the hub must not. Text-to-video is neither. Text-to-video has to invent teeth. Invented teeth are a different match.

What this is not

It is not a gearbox explainer. It is not a text-to-video "CNC sprocket spinning in oil mist" paragraph. It is not a bike-shop cassette ad with an industrial bore in the caption.

Do not I2V a blank hub and hope the model stamps it in flight. Motion will not add a legal part number. It will decorate the blank.

Do not first-last two different tooth counts. The interpolate is a morph of the SKU.

Pause on the stamp. Count the teeth. If the freeze-frame would not pass the catalog, the video will not pass the chain. Ideogram on the hub. Product motion later. Generated teeth never.

FAQ

Can I animate a sprocket photo and hope the stamp holds?

Only if the stamp is already sharp in the still. Image-to-video interpolates the teeth it can see. It will not letter a missing pitch, and it may grow a tooth. Type-lock first.

Why not overlay the pitch on a generated gear and skip Ideogram?

Overlay is a caption, not a hub. Purchasing looks at the metal. A pretty generated profile with a burned 40B18 is still a cousin tooth. Stamp the hub in the still.

Is this the bike-shop cassette job?

No. Bike shops are a retail floor. This is the OEM hub stamp — pitch, count, bore — on an industrial SKU. A cassette hero is a different plate.

What if the real hub is blank until after heat treat?

Then the listing still is not ready, or you Ideogram a catalog-accurate stamp you already own as artwork. Do not ask a video model to invent the characters that engineering has not released.
