Heat-shrink recovers from expanded tube to tight jacket as two frames
Expanded sleeve, then recovered jacket, same cable and print. First-last. A model that changes the legend sold a different ratio.
Expanded sleeve, then recovered jacket, same cable and print. First-last. A model that changes the legend sold a different ratio.
Heat-shrink is a recover. Frame A is the expanded tube on the cable you actually sell. Frame B is the jacket after heat, tight, print still readable, same legend. Interpolation is the ad. A generate that rewrites the ratio mark, the agency print, or the cable diameter sold a different part.
Two states of the same print
Photograph the expanded sleeve where it sits on the conductor — same lens height, same bench, same lighting family. That is the first frame. Photograph the recovered jacket on that same run after the heat cycle, or from a second approved still of the same SKU in the recovered state. 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 cable, same print colour, same legend. A close-up of expanded polyolefin morphing into a wide of a different spool is a warp, not a recover. Keep the bench. Keep the print.
If the recovered still shows a different ratio stamp — 3:1 becoming 4:1, a wall-thickness mark that moved — stop. That pair is two products. The model will connect them. The connection is the artefact a buyer who stocks your line will notice.
Prompt the travel, not the objects. The stills already contain the sleeve and the jacket. Name the mechanism: heat recover, camera locked, print holds, no new legend. If the endpoints share geometry, the morph reads as shrink. If they do not, you get a mushy crossfade.
VEO first-last is the short 4K interpolate
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 catalog lists 40 credits.
Use it when eight seconds is enough recover and the plate is a hero. A sleeve that seats in two seconds looks padded at eight. There is no ninth second on this row. A 12-second recover is not this model with the slider imagined further to the right.
Audio is on. A silent prompt still gets a soundtrack you did not choose. Write room tone, no voice, or plan to replace the mix. First-last interpolates a sleeve. It will not lip-sync a script about ratings.
4K is the ceiling, not a default. Spend it when the print has to survive a pause on a datasheet page. The sticker is 40 credits either way. The waste is the wrong pair, not the badge.
Flux 3 first-last is the longer recover
Flux 3 First Last Frame to Video is the longer interpolate: 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 or write silence. A silent brief still gets a soundtrack you did not choose.
Size the interpolation to the change. A tiny recover does not need 20 seconds. Prove the pair at 5s or 6s. Climb only with a reason that survives a pause on the legend. Qualities go to 1080p. Do not brief 4K. If the master spec is a 4K plate, you are on VEO first-last for the short recover.
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 recovered jacket is a different job.
The electrician page is a panel story, not this ratio
AI video for electricians is the contractor brief: panel work, safety explainers, "don't DIY this." That is a nearby audience. It is not a heat-shrink OEM listing. Copying a hazard-find reel onto a 3:1 sleeve is how a ratio mark becomes a talking van.
This page is the SKU: expanded tube, recovered jacket, print that would survive a distributor pause. Overlay the ratio you will stand behind after lock if the stills themselves should not carry extra type. Do not ask the interpolate to letter "3:1 dual wall" onto a sleeve that does not show it. A model that invents a legend sold a different part.
Wrong jobs: text-to-video that invents the print; a one-still wiggle of the expanded tube; a loop with the same still in both slots; a last frame from a competitor catalog. The model will connect whatever you give it.
Would you print both stills on a datasheet? If either legend is wrong, stop. If both are right, bound the travel and watch the stamp. If the stamp moved, you sold a morph.
FAQ
Can I animate one photo of the expanded tube and hope it recovers?
You can. The ending is then the model's guess. Heat-shrink is the tight jacket with the same print. Pin the recovered still as the last frame or you are not selling the recover.
Why would the legend change mid-clip?
Because the two stills disagreed, or because the prompt re-described the ratio. First-last has to land. If the landing print is a different mark, you sold a different SKU. Reshoot the pair.
Which row for a datasheet hero versus a feed clip?
VEO first-last is 4s / 6s / 8s, 4K available, 40 credits, native audio. Flux 3 first-last is 5s–20s, 720p/1080p, 9 credits per second, native audio. Short hero with a 4K need: VEO. Longer recover on feed: Flux. The agent is the named two-still job.
Is this the same as /for/electricians?
No. That page is local panel and safety for a contractor. This page is the OEM recover of a specific sleeve. Do not paste a "signs you need an electrician" hook onto a ratio stamp.
