Fiber-laser welders: Hailuo 2.3 Fast I2V the keyhole at 28cr discounted

Hailuo 2.3 Fast is discounted image-to-video at 28cr for 6s or 10s: keyhole motion after the welding-head still; audio is null so do not expect a generated hiss, and skip a talking welder.

A fiber-laser clip that books is the keyhole you can see on this head: nozzle family, assist-gas ports, the collimator, the standoff you actually ship. A constructed welder walking “what you should set on this wattage” is a second file, with a real named person, on a different day. Do not glue those jobs into one generate.

The welding-head still is the start

Photograph the head you sell. Square to the nozzle. Gas ports readable. Cable bundle in frame if that bundle is the SKU. That file is frame one. Text-to-video will invent a cousin torch with a different nozzle OD and a cleaner cable. The buyer is matching iron, not atmosphere.

Image-to-video starts from the frame you upload. Composition, the ceramic, the standoff — already decided. The prompt names only movement: the keyhole forms, a slow travel along a bead, a light rake across the nozzle. Leave “6 kW fiber laser, cinematic shop, sparks” out of the paragraph. Repeating the spec in text is how the model renegotiates the spec.

Turn a photo into a video is the named agent job for the same empty-handed-of-words start: one still in, a short clip out. Cost is priced per model, shown before you confirm. Name Hailuo 2.3 Fast if the duration stairs and the silent file are the point.

If the still would not attach to the work order — wrong nozzle, a colourway you do not stock, a glove you cannot release — stop. Crop or reshoot. Do not prompt the glove out and hope the model rebuilds the head.

Zoom to 100% on the nozzle before you keep a take. Fine geometry is the first thing a generator loses. A melted ceramic is a different SKU.

Hailuo 2.3 Fast is 6s or 10s, 28cr discounted, audio null

Hailuo 2.3 Fast is MiniMax Hailuo 2.3 image-to-video: a single still in, a short cinematic clip out. Category is image-to-video only. An image is required. Durations: 6s and 10s. Catalog list is 28 credits, marked discounted. Max output resolution is unset on this slug. Do not invent 1080p or 4K. Catalog audio is null — not a native-audio promise.

Those two durations are stairs, not a trim. There is nothing between 6s and 10s. A seven-second idea buys the 10s SKU. Fit the keyhole to six seconds, or commit to ten. Do not write “about 7 seconds” and discover the staircase at confirm. 3 Hailuo 2.3 rows sell only 6s and 10s is the leftover staircase map. This page is only the welding head.

Start at 6s until the nozzle holds. Ten seconds of a drifting ceramic is not more professional. Identity drift likes the long end. A 10-second miss is a long miss of a melted collimator.

The prompt is for travel: how the keyhole opens, how far the head moves, what stays still. If you re-describe the product, Fast will argue with the pixels. Wattage, nozzle OD, and “nitrogen assist” belong off the generate. Overlay them after lock if they must appear.

Because audio is null, this clip is silent. Do not write a VO into the Fast prompt and wait for a voice. Add voice later on a plate with no lips, or do not add voice.

Keyhole motion, not a talking welder

Keyhole is physics on the photographed head: a vapor cavity, a travel, a bead that must not invent a second nozzle. Prompt the travel. Do not prompt a person.

Skip a talking welder. A constructed technician pointing at a cutaway and prescribing parameters is a presenter you did not hire. Put a real named person on camera when the video tells a viewer how to set a unit — or do not tell them. Generation can still do the head.

Do not:

• Prompt “welder explains keyhole over the torch.”
• Use lipsync on a generated face holding “your” head.
• Let Fast typeset wattage into the collimator.
• Ask the model to invent a hiss so the clip “sounds like welding.”

Silent keyhole. Overlay the spec. If a human must speak, that human is on payroll and on a different take. The welding-head still stays first.

/for/manufacturers is the plant page — chips, docks, a line you already film. This page is fiber-laser OEM: one head, one keyhole. Do not rewrite the plant tour as a talking process lesson, and do not replace this SKU with a generic “industrial laser” paragraph.

Do not expect a generated hiss

audio is null. Hailuo 2.3 Fast will not hiss assist gas, crack a plasma, or invent a VO. Score it after picture lock. Do not file a bug on a row that does not list audio. Do not prompt quoted “real welding sound” and expect a mix.

If you needed a shop bed, that is a later audio job on a plate with no mouth. If you needed a caption, burn a line you wrote. Auto-captions listen. A mute head has nothing to transcribe.

A last frame is useful only when you have a second approved still of your head — cold nozzle to a short bead, same camera. Do not invent a cutaway of a weld pool you did not photograph. A generated cross-section of a keyhole is a drawing of internals you never saw. Hold the head. Speak claims you can defend, or overlay them as type you wrote.

Pause on the nozzle. Is it the head in the quote? Yes: ship. No: you used text-to-video, or you first-last’d two SKUs. Go back to the still.

FAQ

Can I prompt Hailuo 2.3 Fast to “match this welding head” instead of uploading it?

No. A sentence is not a plate. Fast requires an image. Upload the head to Hailuo 2.3 Fast and describe only the keyhole travel. Text-to-video of a torch rebuilds a cousin nozzle.

Does Fast add native audio if I ask for a shop bed?

No. Catalog audio is null. The clip is silent. Score later. Do not expect a generated hiss, a plasma crack, or a VO from a row that does not list audio.

Can I generate exactly seven seconds of keyhole?

No. Fast publishes 6s and 10s and nothing in between. A seven-second requirement is rendered at the 10s tier. Fit the travel to six seconds, or commit to ten and trim after. Trimming refunds nothing.

Why not a talking welder for “explaining” the keyhole?

Because the keyhole is visible on the photographed head, and wattage is a number. A constructed tech is a second asset you do not need. Hold the nozzle. Caption a human only if a real human is speaking.
