Rethink a moment inside an existing video.
Sometimes the next creative step is a specific change. Nortes Replace Mode starts with an existing video and a natural-language instruction, then helps locate and revise the relevant segment so you can review a new version.
Describe the change with enough context
Bring the existing video, a clear instruction and optional reference images. Specify the subject, the intended appearance and the moment that matters. Useful context makes it easier to judge whether the new version addresses the request, rather than merely looking different.
Locate the segment you want to work on
Use automatic location or manually select the relevant time range. Review that selection before continuing. A focused range helps keep the creative decision understandable, but you should still inspect surrounding frames and continuity in the result.
Generate, compare and keep refining
Review the revised segment and its history, then continue iterating where needed. Check the requested change, product details, motion and how the segment relates to the rest of the video. Generation can require refinement; the workflow does not promise a flawless edit on the first attempt.
Choose the entry that matches the job
Replace Mode edits a segment of an existing video. Reference Creation analyzes an example to build a new product-led plan. If the existing clip is just inspiration and you want a different structure or story, the reference workflow is a more appropriate starting point.
Clarify one moment in a product shot
Select the time range where a product is shown, describe the visual detail that should change and provide an accurate reference image if helpful. Review both the edited area and the surrounding motion before continuing. This is an illustrative editing brief.
A few things before you start
Can I select the time range manually?
Yes. The mode supports manual time-range selection as well as automatic location of the relevant segment.
Are reference images required?
They are optional inputs alongside the existing video and a natural-language instruction. Add them when they help explain the intended change.
Can I review previous versions?
Replace Mode provides edit history so you can inspect revisions and continue iterating on the selected work.
