Yes — describe the order you want, or upload them in the sequence you'd like used. If you don't specify, the agent will use a sensible default order based on how they were provided.

You can request a name, age, a short message, or multiple lines at different points in the video (e.g. a title at the start and a closing message at the end). Very long paragraphs of text are harder to fit cleanly into a short video.

Yes — describe what you want: fades, zooms, quick cuts, or a slower crossfade. If you don't specify a style, the agent picks a simple, clean default.

Typically a short clip — around 10-30 seconds for a handful of photos, longer if you provide more photos or ask for a slower pace. This is meant for quick shareable clips, not a long-form video.
