Show HN: Viral Video AI – Short videos from text, photos and video references

Viral Video AI generates 4–30-second vertical social clips for TikTok, Reels, or Shorts from a text prompt, up to 9 photos (Basic) or 30 (Pro), or one reference video, with Basic offering 4–15 s at 480p/720p and Pro extending to 30 s and 1080p. Users can paste a public TikTok, YouTube, or Instagram URL to preview a clip as a reference, and the tool shows a credit quote that updates with media and settings before generation. The page states no exact match to references is guaranteed and notes platform disclosure rules for realistic AI content.
