Fishfinder bezels overlay kHz; Imagen 4 at 4cr, 4K is the spec card, never a fake return

Photograph the bezel you sell and overlay transducer frequency as authored type. Imagen 4 is text-only, 4K, 4cr for the spec card — it will not paint a real sonar return, and a generated waterfall is a fake fish. Boat-dealer hull stills are a different SKU.

A fishfinder listing that ships is the head unit you hang: this bezel, these keys, this display housing, this transducer-frequency class. kHz is a string from the cut sheet. A generated sonar waterfall is a catch nobody logged. Photograph the face. Typeset 50/200 or the CHIRP band you actually ship. Leave the arches off the generate.

Photograph the bezel you sell

Procurement matches geometry: the gasket line, the key layout, the sun-cover hinge, the colour of this face. Text-to-video of “a fishfinder painting fish on a lake at golden hour” invents a cousin glass and a cousin catch. That is a different SKU and a fake return.

Photograph the unit you ship as a catalog plate: square-on or three-quarter, screen off or showing a still you actually captured on water, no invented arches. Do not prompt “show it finding fish.” Finding fish is a return you did not record.

AI product video is the object-hold door. Two or three clean angles of this bezel are the contract — keys, imprint, transducer port. Zoom to 100% before you keep a take. Prompt only the camera: a slow orbit, a hold on the face. Do not prompt “big fish hitting the screen, cinematic sonar.” If the still would fail a dealer audit — wrong key count, a sister model’s paint — reshoot.

Boat dealers: the hull still is the SKU already owns the hull photograph: sheer, transom graphic, the outboard that is actually hung. This leftover is fishfinder OEM: one bezel. Do not paste a generated console onto a hull you did not photograph.

Imagen 4 is the 4K spec card, not a sonar paint

Imagen 4 is Google’s text-to-image row: photoreal, text-only, 4K, 4 credits. Category is text-to-image. audio is null. No duration. It cannot ingest the bezel photo. A paragraph is the whole brief. That is a spec card, not a live return.

Use it when you need a closed product still of the head unit you sell — quote bezel colour, key layout, no water, no fish — and you will label the picture as a product render, not a day on the lake. If a dealer who stocks the SKU would not say the card is this face, you generated a cousin glass.

Text-to-image is the door. Name Imagen 4 when the card has to be photoreal at 4K and you do not have a clean pack shot yet. Four credits is the listed rate. It is not a waterfall renderer. Do not prompt “photoreal sonar screen full of arches, 200 kHz, trophy bass.” That painting is a catch. 4K makes the fake sharper.

If you already have a photograph of the bezel, that JPEG is a better first frame. Imagen cannot hold the serial you skipped. Keep Imagen for a labeled spec-card render, or skip it.

Do not ask Imagen to letter kHz into the glass. Prompted glyphs on a display are a frequency you cannot edit when the SKU changes from 83/200 to a CHIRP band.

Overlay kHz after picture lock

Transducer frequency is a claim. 50/200 kHz. CHIRP 150–240. Those digits are why a buyer opens the listing. A 200 that becomes an 83 for six frames is a different cone. Video models redraw letterforms every frame. They also redraw the screen. Both are failures.

Add a text overlay to a video burns one authored line for the whole clip — top, center, or bottom. That is the frequency string you already print. It does not transcribe. Write it from the cut sheet. Picture lock, then type. Crop to the ship ratio before you overlay; top / center / bottom sit in a different safe zone after a 9:16 reframe.

If the photographed bezel already carries a sharp frequency imprint you actually silkscreen, keep it. Do not “enhance” the print. If the digits are unreadable, overlay the string from the listing. Do not generate a glowing kHz on the glass and call it the spec.

Frequency, then a dual-frequency beat, then a CTA is timed overlays, a different editor job. Auto-captions listen. A silent head unit has nothing to transcribe.

A generated waterfall is a fake fish; hull stills are a different SKU

A sonar waterfall is a record of a ping. Arches, bottom, thermocline — those are data. A model asked to “show the unit working” will invent fish. That is a catch you did not log, and in this category it reads as a return. Do not first-last a dark screen to a painted waterfall. The middle of that interpolate is a fake fish.

Do not text-to-video a trophy bass exploding under the transom so the bezel has a scene. That hull is boat-dealer inventory. That fish is a claim. This page is the head unit.

Allowed: the photographed bezel, an Imagen spec card labeled as a render, authored kHz. Not allowed: a generated sonar page, a generated catch, a generated skipper pointing at arches. If someone must speak a transducer lecture, that someone is a real named person on a different day.

Pause on the glass. If an arch appeared that was not in the still, you made a return film. Crop it or reshoot.

FAQ

Can Imagen 4 paint a realistic sonar waterfall if I quote 200 kHz in the prompt?

No. Imagen 4 is text-only, 4K, 4 credits. It will invent a screen. Photograph the bezel. Overlay the frequency. A generated waterfall is a fake fish.

Why overlay kHz instead of asking the model to typeset it on the glass?

Because frequency is a claim that changes by SKU. Add a text overlay burns one authored line you can swap. Prompted glyphs are a miss you regenerate to fix.

Is this the same as the boat-dealer hull still?

No. Boat dealers hold the hull photograph. This leftover is fishfinder OEM: one bezel, an Imagen spec card if you need a 4K render, authored kHz. Do not glue a generated console onto a hull walkaround.

Should I skip the product photo and let Imagen invent the bezel?

You can. You will get a glass with keys. It will not be the face often enough to run as the listing. Photograph the unit you ship. Use Imagen 4 for a labeled spec-card render, never as a live return.
