A size guide already has the number. Fifty feet, the height of a fridge, twenty meters, fifty-two inches. A short clip helps when a reader can see that length beside one familiar object. It misleads when the picture shows a different length, or when digits on the screen print a figure the article never stated.
Show one comparison
Pick the length the paragraph already gives, and one object the same paragraph uses to explain it. A doorway, a bus, a room. One comparison fills a short clip. A second measurement that the guide does not contain should stay out of the picture.
Read the frame before you keep it. Generated digits are a common place for a wrong figure. The number in the sentence is the number to publish.
A clip long enough to see the length
Seedance 2.5 generates that clip at about 4 to 30 seconds, from text plus image, video, and audio, with the timing written in seconds. You can bring up to 50 references: as many as 30 images, 10 video clips whose combined length stays inside 30 seconds, and 10 audio files on the same combined limit. A reference image on this page can be up to 4K. The video export you can select tops out at 1080p. The page can also carry dialogue and subtitles in more than one language. If one second is wrong, that section can be revised while the rest stays more stable. Trial credits are shown before you generate. They are not an unlimited run, and a free pass may use a narrower preset. Commercial use depends on the plan and the license at export.
Leave the draft next to the sentence
Topview is the workspace around that clip. You describe the idea, paste the size paragraph, add a reference for the pace, or point at the page that states the length. The scenes stay editable, so a correction to the number is a correction to the shot. The plan and the credits are on the site before you generate. The workspace does not publish the guide. A generated frame stays a draft until the length on screen matches the length in the sentence.
A talking face is not a measuring tape. If a person has to appear, use a photograph they agreed to. Otherwise leave them out of the clip.
