Make the contents understandable
A digital product preview should show what a buyer receives. Start with a representative page or cover image, then show a useful interior detail. For a planner, compare the overall layout with a close view of the writing area. For a worksheet, show an example task and the available answer space. Export screenshots from your own source document before uploading them; this template does not read a PDF or crawl a store URL.
Explain the delivery format honestly
Use the caption area to describe the actual download format and intended use. A flattened preview does not prove that the source is editable, and a page shown inside a mockup does not make it a physical product. If your listing includes a PDF, say so. If it includes editable source files, verify those files separately. The video is a marketing preview, not the digital product delivery package itself.
Keep preview text readable
Small spreadsheet cells or a complete twenty-page workbook will be unreadable in a short video. Crop a representative view before uploading, and reserve the on-screen captions for a short explanation. Both images keep their proportions. Use landscape for wide pages and square or portrait for compact previews; inspect the rendered MP4 on a phone before publishing it.
Reuse a project without creating duplicate pages
Save the two source images, title and captions locally, then restore the latest project from this template page. The completed MP4 can also be recovered while this browser retains its site data. Closing the tab during rendering interrupts the job; reopening restores the editable inputs and prompts you to render again. There is no background cloud queue and no model credit charge for this local renderer.
