Free AI Video Generator

Turn a topic into a finished video — AI script, voice, captions, music plus Pexels stock and AI b-roll images, assembled into a 60-second mp4 ready to upload.

Why ViralMint for this

01

Full pipeline, not just one step

Pictory generates videos from a script you write. Lumen5 turns articles into slideshows. Synthesia is for avatar videos. ViralMint runs the whole pipeline end-to-end: AI script → AI voice → Whisper transcription → caption timing → AI music → Pexels stock + AI-generated b-roll images (Nano Banana) → animated word-by-word captions → mp4. One topic in, one finished video out.

02

Stock + AI imagery, no frame-by-frame video gen needed

Daily-cadence faceless TikTok / Shorts content rarely needs Sora-grade frame-by-frame video — Pexels stock keyword-matched to your script, blended with AI-generated b-roll images via Nano Banana (Google Gemini 2.5 Flash Image), does the job at a fraction of the cost. AI script + AI voiceover + AI music + Ken Burns motion finish the look. Typical 60-second video: ~$0.05–$0.08 in cloud calls.

03

Word-by-word captions baked in

Every video ships with the TikTok-viral caption style — one or two words at a time, synced to the speaker. Three preset styles (viral / classic / bold) cover the full range. No separate captioning step, no Submagic subscription on top.

How it works

  1. Open Smart Video on the desktop

    Launch ViralMint, click Smart Video in the sidebar. The page accepts a topic, a hook, or a downloaded competitor video as a transcript reference.

  2. Pick aspect, voice, music genre, caption style

    9:16 (TikTok / Shorts), 16:9 (YouTube), 1:1 (Instagram). 13 voices including Marin and Cedar. 12 music genres. Three caption styles (viral / classic / bold). Defaults are sensible — most users only change the aspect ratio.

  3. Review the script + cost estimate

    ViralMint generates an AI script you can edit, then shows the estimated cloud cost (typically $0.03–$0.08 for a 60-second video — AI script + AI voice + AI music). The Pexels stock footage layer is free.

  4. Click Generate

    ViralMint runs the 11-step pipeline: AI script generation → voice → Whisper transcription → Pexels stock + AI b-roll images (Nano Banana) → music mixing → audio merge → animated caption burn → thumbnail extract → metadata draft → save. A 60-second video typically completes in 1–3 minutes.

Frequently asked

What does the free tier actually include?

The Pexels stock-footage layer is free at the per-clip level — ViralMint uses Pexels' free API to pull keyword-matched stock clips for each scene. You still pay for cloud-routed parts (AI script, AI voice, AI music — transcription is local) but those are pennies. A typical 60-second video costs about $0.05–$0.08 in cloud calls.

Does ViralMint use frame-by-frame AI video generation (Sora / Veo / etc)?

Not in v1. The Smart Video pipeline assembles videos from keyword-matched Pexels stock footage blended with AI-generated b-roll images (Nano Banana / Google Gemini 2.5 Flash Image), then layers AI script, AI voice, AI music and word-by-word captions on top — that combination is enough for daily faceless TikTok / Shorts content at a fraction of the cost. Frame-by-frame AI video gen is a roadmap item for later, but isn't shipping today.

How long does a video take to generate?

A 60-second video typically completes in 1–3 minutes — the bottleneck is voice synthesis + music generation, not video assembly. The desktop app shows per-step progress so you can leave it running and check back.

Can I edit the AI-generated script before the pipeline continues?

Yes — there's a Script preview step where you can edit the AI's output before voice generation runs. You can also bypass AI script entirely by pasting your own.

Does it work with my own footage?

Yes. Smart Video accepts user-uploaded clips alongside (or instead of) stock — the desktop app's Mixed Clip Assembly mode mixes them with Pexels footage based on script scene matching. Useful when you want some real footage of yourself plus stock for the rest.
