Plate packs open and close as a first-last, not as Omni B-roll
Closed pack then opened pack on the same frame and gasket set is first-last, not Omni dairy-hall B-roll.
Closed pack, then opened pack, same frame and gasket set. First-last. Omni B-roll of a dairy hall is not this SKU.
A plate-heat-exchanger OEM does not sell a misty plant. It sells a pack: plates, gaskets, the frame that holds the stack, the ports you actually machine. The motion that proves the product is open and close on that unit. You already own both stills. Interpolate. Do not prompt a model to invent a pasteuriser hall and hope a cousin pack appears in the steam.
Frame A is closed. Frame B is open. Same iron.
Photograph the pack closed — same lens height, same bay, same port orientation. That is the first frame. Photograph the same pack opened: plates visible, the same gasket compound, the same end connections. That is the last frame.
First-last frame takes those two stills and generates the motion between them. Ordinary image-to-video knows where it begins and improvises the rest. First-last has to land. The arc of the shot is decided by you.
The two frames have to be plausibly connectable in the time available. Same unit, same lighting family, same camera. A closed isometric morphing into a wide of a dairy hall is a warp, not a service demo. Keep the frame rails in both stills. If the gasket set changes between A and B, you advertised a rebuild, not an open.
Prompt the travel, not the objects. The stills already contain the pack. Name the mechanism: hold, then the follower moves, plates separate, camera locked, no new ports. If the endpoints share geometry, the morph reads as a rack opening. If they do not, you get a mushy crossfade you could have made in an editor without a video bill.
Flux 3 interpolates the service motion
Create a first-and-last-frame transition video is the named agent job: two photos in, one transition out. The agent passes them as first and last frame and picks a first-last-capable model. Cost is priced per model, shown before you confirm. This is not the plain "turn one photo into a video" capability. Missing the open pack is a different job.
Flux 3 First Last Frame to Video is the catalog row for that interpolation: start frame and end frame, native audio, 720p or 1080p, durations from 5 seconds through 20. The listed rate is 9 credits per second. Audio is on — write the mix (a quiet shop, a follower rumble) or write silence. A silent brief still gets a soundtrack you did not choose. Say so, or plan to replace the bed.
Five seconds is a short crack. Twenty seconds is a long service. Match the clock to how far the follower actually travels. A 20-second interpolate of a 2-centimetre gap is a hold you did not need to buy. A 5-second interpolate of a fully spread pack is a warp.
Veo first-last is the short 4K sibling
VEO First Last Frame interpolates between first and last frames. Native audio is on. Durations are only 4s, 6s, and 8s. Output quality includes 720p, 1080p, and 4K. The sticker is 40 credits. There is no ninth second on this row. An eight-second open of a small sanitary pack can be enough. A full industrial spread is not this model with the slider imagined further to the right.
Styles on the Veo row flavour a travel you already bounded. They do not replace a missing last frame. 4K is the ceiling, not a default you owe every take. Spend 4K when the plate is a hero. The waste is the wrong job — a dairy hall from a paragraph — not the badge.
Audio rides along on both Flux 3 and Veo first-last. If you will score later, refuse the bed in the prompt or replace it. Do not discover a documentary swell under a gasket you meant to keep mute.
Omni B-roll is a different film
Gemini Omni Video is multimodal video: a prompt plus optional references, 4s / 6s / 8s / 10s, up to 4K. Audio is empty on this row. It will invent a plant. That is useful when you wanted a generic hall. It is not a plate pack. A dairy mist with a heat exchanger in the background is a cousin of a cousin. The gasket compound will be wrong. The port count will be wrong. The frame will be wrong. You cannot overlay a model number onto a unit the sampler built.
Do not use Omni as a shortcut around two stills. One reference of a closed pack plus "now open it in a creamery" is still a generate of a hall. First-last is the product-turn. Omni is B-roll of a place.
/for/manufacturers is a plant-story audience. This page is the pack SKU. A contractor who installs the unit is a third still — the bay, the piping, the real room. Do not rewrite those pages. Photograph the closed pack. Photograph the open pack. Interpolate. Overlay the plate count and the gasket compound after picture lock, as type you typed.
A loop (the same still in both slots) is ambient motion on one plate. This offer needs two states. Closed, then open, same iron.
FAQ
Can Omni open the pack from one still?
It can invent an opening. The landing will not be your gasket set. Pin the opened pack as the last frame or you are not selling the service motion.
Why do the two photos need the same frame and gasket set?
Because first-last connects whatever you give it. Different frames are a morph. Different gaskets are a rebuild. The product is one unit, two states.
Flux 3 or Veo first-last?
Flux 3: 5–20 seconds, 720p/1080p, native audio, 9 credits per second. Veo: 4 / 6 / 8 seconds, 4K available, native audio, 40 credits. Pick by travel time and whether 4K is the plate. Both need two stills.
Is this the same as manufacturer plant B-roll?
No. Plant B-roll is a hall. This is the pack opening on rails you photographed. Omni will give you the hall. First-last gives you the SKU.
