# Viral Video Generator > AI viral video generator for reference-guided short-form video creation. Personalize a reference with one to three authorized adult photos, depending on the template and download a 720p MP4 for TikTok, Instagram Reels, or YouTube Shorts. ## Core product facts The current workflow is reference-guided, not a blank text-to-video or script-to-video editor. It preserves the source composition, timing, and audio direction while replacing assigned roles. Previewing templates, selecting photos locally, reading guides, and creating an account are free. Video generation costs 2 credits per reference second, rounded up to 5 credits. The current 21.08-second template costs 45 credits. Confirmed failed generations return the credits spent. AI cannot guarantee views, engagement, or virality. Review identity consistency, motion, audio, permissions, and current platform AI-disclosure rules before publishing. ## Pages - [Viral video generator](https://aiviralvideo.net/) - [Deck the Halls AI Christmas dance video maker](https://aiviralvideo.net/deck-the-halls-ai): English guide and generator for a user-supplied reference clip with one- or two-photo role replacement, a 14.42-second 9:16 MP4 at 720 × 1280, and a 30-credit generation cost.
