1. Select one usable source
Start with an authorized report, brief, presentation, spreadsheet, text file, Markdown file, or PDF. The source should be authorized, stable, and narrow enough to understand in one pass. FluxKlein sends the selected reference context to Wan 3.0; it does not crawl an entire private workspace or combine an unlimited asset library. Remove confidential information, confirm that remote pages open without authentication, and choose the source that best represents the message you want the finished video to communicate.
