Piston-filler strokes stay silent on Wan 2.5 I2V at 15cr

Wan Video 2.5 I2V is audio false, 15cr, 5s or 10s at 1080p: piston travel on the photographed cylinder only. Native-audio T2V on the same family is a different row and will invent hiss you did not record. Homogenizer poppet travel already shipped.

A piston-filler clip that books is the piston travelling on this cylinder. Bore, packing, the nozzle face, the stroke you actually ship — those are the SKU. Hiss is a recording. A constructed dairy hall with a cousin valve is a plant tour you did not film. Do not glue those jobs into one generate.

The photographed cylinder is the leftover SKU

Photograph the filler you sell. Square to the cylinder. Stroke in frame. Ports readable. That still is the print. Text-to-video will invent a cousin barrel with a cleaner paint job and a different nozzle. The buyer is matching iron, not atmosphere.

Image-to-video starts from the frame you upload. Frame one is the file. Re-describing the bore in the prompt is how the model starts drawing a second cylinder.

This leftover is piston-filler OEM: one cylinder, one silent stroke. Do not rewrite a plant tour as a talking fill-volume lecture, and do not replace this SKU with a generic “liquid filler” paragraph.

Prompt camera and physics only. Piston extends. Piston retracts. Camera locked. No new ports. No new nozzles. If the still includes a scale or a serial, keep it. A stroke that lengthens into a different opening mid-clip sold a different fill volume.

Wan 2.5 I2V: silent, 15cr, 5s or 10s, 1080p

Wan Video 2.5 Image to Video is high-quality image-to-video with Wan 2.5. Category is image-to-video. Requires an image. Audio is false. Durations: 5s and 10s. Max output: 1080p. Display price: 15 credits. The still is the brief. The model moves it.

Wan Video 2.5 Image to Video: the still is the contract is the row’s own contract. This page only spends it on piston travel.

The AI image-to-video tool is the door. No still, no generate. A paragraph where the cylinder should be is a wrong label. Every second of the 5s or 10s is waste.

Fifteen credits is cheap enough to retry, not cheap enough to retry the wrong plate. 5s is a gesture. 10s is a beat. There is no 4s, 6s, or 8s chip on this slug.

1080p is the ceiling. Quality chips include 480p and 720p on the way up. Motion levels listed are Medium and High. Medium on an approved cylinder is often the whole job. High on an unapproved composition is 10s of drift and a new nozzle.

audio is false. 5s and 10s come back silent. Prompting a valve hiss here does not buy a soundtrack. It may smear the plate with painted words. Score later. A mute cylinder has nothing to listen to.

The prompt is travel. Piston seats. Piston lifts. Camera locked. No hall, no operator, no new bore. Volume and a quoted millilitre belong off the generate. Overlay them after lock if they must appear.

T2V on the same family invents hiss you did not record

Wan Video 2.5 Text to Video is the sibling slug: no still required, 1080p ceiling, 15 credits, durations 5s and 10s only, audio on. Native audio means a silent prompt still gets a soundtrack you did not choose. Write the room and the none, or plan a replace pass. Do not paste a T2V prompt into the I2V row and hope.

T2V invents the frame. If the cylinder must match a catalog photo, T2V is the wrong door. It will sample another guess of a barrel, then score a hiss nobody recorded. That hiss is not your plant. Fifteen credits of native-audio cinema does not restore the piston you skipped.

Do not run T2V “piston filler cycling, realistic air hiss, dairy hall.” Do not expect I2V to unmute because the sibling has audio. Do not treat a 15-credit T2V miss as a cheaper way to skip the photo.

Wrong label: running the I2V slug without an image; expecting native audio on I2V; expecting T2V to hold the serial. Correct label: approved still, 5s or 10s, up to 1080p, silent, 15 credits, Wan 2.5 image-to-video.

Styles listed on I2V (Cinematic, Documentary, Abstract) shift motion register. They do not unmute audio. They do not remove the image requirement.

Homogenizer poppet travel already shipped

Homogenizer valves pop in Kling 3 Turbo; do not Omni a dairy hall already owns the leftover head: seat, stem, the gap at operating pressure. That poppet already shipped. This leftover is piston-filler OEM: photographed cylinder, silent Wan stroke.

Do not restage a two-stage homogenizing valve so the filler has a dairy hall. Operating bar is a homogenizer claim. Fill volume is a piston-filler claim. Both are overlay. Mixing the two machines in one prompt is how you ship a poppet with a filler nozzle welded on.

Do not morph stroke on either Wan row. If the still shows a short travel, the clip may not finish as a long dump. Those are claims. A buyer will notice them before they notice your logo.

Silent piston. Overlay the spec. If a human must speak, that human is on payroll and on a different take. This SKU page cannot borrow a plant tour as a generate.

FAQ

Does Wan 2.5 Image to Video need a still of our cylinder?

Yes. Category is image-to-video. Audio is false. 5s or 10s, up to 1080p, 15 credits. If you only have text, you are on Wan Video 2.5 T2V, and that row will invent a cousin barrel plus a hiss you did not record.

If I do not mention sound on T2V, is the clip silent like I2V?

No. T2V has native audio. A picture-only prompt still returns a soundtrack the model chose. I2V is audio false. Do not mix the slugs.

Is this the same as homogenizer poppet travel?

No. That leftover is the photographed homogenizing head. This leftover is piston-filler OEM: silent Wan 2.5 I2V on the photographed cylinder. Do not mix the machines in one generate.

Can I generate 15s or 30s of stroke here?

No. Durations on both Wan 2.5 rows are 5s and 10s. A longer need is a different row or an extend pass, not a prompt trick on this slug.
