Terrazzo chips cannot morph; lock the pour, then grade

Luma Ray 2 at 50cr (720p, 5s/9s) is the silent HDR polish after the aggregate still is locked; cheap motion smears the mix.

Terrazzo is a chip field. Marble, glass, the binder, the grind that made this floor the floor you poured. A generate that almost looks like last week's mix is a different floor. Motion is allowed. Morphing the aggregate is not.

Luma Ray 2 720p is Luma Ray 2 video generation in 720p quality. Category: text-to-video. Durations: 5s and 9s. Resolution: 720p. Credits: 50. Audio: empty. No image required. That empty audio field is the product: a silent 720p plate you can score and grade later. It is not a native-audio talking row. It is not a 1080p switch. It is not a 16-bit HDR10 master — if the brief named Rec.2020 PQ or HLG at 1080p, this row is the wrong original. Fifty credits buys 5 or 9 seconds of 720p silence after you already know what the chips look like.

The pour still is the mix

A terrazzo listing is a specific object. The buyer knows the chip size, the colourway, the binder. Text-to-video does not. It invents a generic polished floor: pretty, plausible, a cousin aggregate. That is a different pour. The contractor who paused on the glass chips notices before they notice your logo.

Photograph the approved pour the way you would print a sample board: square-on, chips true, grout lines readable, no invented type in the binder. Lock the still before you spend on motion. Iterate the still until someone who poured it would ship the board. Then decide whether the next credit is atmosphere or identity.

Cheap motion is how the mix dies. A short image-to-video take that "adds cinematic camera" will smear marble into mud, grow extra glass, and heal a joint that the grind left. Drift is a different SKU. If the chips have to be this pour, the upload is frame one and the prompt is only travel: a slow dolly, a light sweep, the camera, not a new mix.

Identity is the product generator; polish is Ray

AI product video is the SKU contract: the object in the ad is the object you photographed. Animate the locked pour there when the chip field has to survive. Image-to-video is the same door for a still that must remain frame one. Prompt camera and physics. Do not re-describe "Venetian terrazzo, warm marble, brass divider." That paragraph restages the floor.

Ray 2 720p does not require an image. If you run it as the listing, it will invent a cousin of your mix. Leave the T2V row for the listing. Use it as the silent polish after the aggregate still is locked: a 5-second or 9-second 720p hold of floor light, no mouth, no soundtrack, fifty credits, so you can grade and score in the editor. The 9-second take is the expensive sibling of the 5-second one, not four free seconds. Start at 5s until the light is the brief. Nine seconds of smeared chips is a long miss.

Aspects on the row run from 1:1 through 16:9 and 21:9. Pick the shape the platform serves. Cropping 21:9 to 9:16 throws away the only sharpness you bought. 720p is the ceiling. Do not prompt 4K.

Do not write a presenter into the Ray prompt and expect a mouth. Audio is empty. Overlay the mix code after picture lock if a specifier needs the string.

/for/contractors is demo-day, not the chip field

AI video for contractors is the nearby audience: process transparency, what is behind the walls, a demo-day time-lapse, a problem-and-fix on site, a final walkthrough. That page is a general contractor calendar. It is not a terrazzo sample board in motion.

A GC who I2Vs a generic polished floor and captions it as last week's pour has used the wrong still. The grind and the chips are the proof. Mix-name copy can overlay a locked pour plate. It cannot invent the room. Numbers belong on a quote or type you typed. A silent grind is the terrazzo job.

Cheap motion smears the mix

The test is the midpoint. Pause. If the chips would not pass a sample-board check against the photo you locked, the take is unusable. Tightening the prompt with more stone names will not put the glass back. Go back to the still. Shorten the duration. Reduce the motion. A 5-second light sweep on a locked plate is a finished clip. A 9-second "cinematic orbit" is how the model invents a second floor.

Text-only "luxury terrazzo showroom" as the listing invents the mix. A cheap I2V pass that treats chips as texture smears them. A talking installer on the pour is a different audience.

Order: real still of the pour; I2V the product plate if the chip field has to hold; Ray 2 720p for a silent 5s/9s polish after that lock, 50 credits, audio empty. Reverse that order and you will pay video rates to discover the marble changed.

FAQ

Does Luma Ray 2 720p generate native audio?

No. The audio field is empty. Description is "Luma Ray 2 video generation in 720p quality." 5s or 9s, 720p, 50 credits. Plan sound in the editor. Do not write a host into the prompt.

Can I skip the pour photo and T2V the mix on Ray?

Not as the listing. Ray 2 does not require an image; it will invent a cousin aggregate. Photograph the pour. Lock it. Use the product video generator when the chips have to be yours. Ray is the silent polish after that lock, not a substitute for the sample board.

Is this the same job as /for/contractors?

No. Contractors is demo-day and behind-the-walls process. Terrazzo here is the chip field as SKU. A time-lapse of someone else's remodel is not a mix you poured.

Why not a cheaper motion row for a five-second sweep?

Cheap motion is how marble smears into mud. Fifty credits on Ray 2 is the silent 720p polish after the still is locked. If the chips drifted, you did not save the credit. You bought a different floor.
