AI Text-to-Video Generator

AI text-to-video generation produces 5–10 second cinematic clips from a written description. Oakgen lets you pick across Google Veo 3, OpenAI Sora 2 Pro, Kling v3 Pro, Runway Gen-4, MiniMax Hailuo, and 15 more, with per-clip costs from $0.30 (Kling Turbo) to $2 (Sora 2 Pro 4K).

Key fact
Veo 3 includes synchronized audio natively — the only model on Oakgen that generates video with matching ambient sound in a single pass.

Why AI Text-to-Video

20+ video models in one interface
Compare Veo 3, Sora 2, Kling v3, and Runway Gen-4 with the same prompt to pick the right look per scene.
45–90 second generation
Most clips finish in under two minutes. Failed runs never cost credits — we automatically retry on a fallback provider.
Camera + motion controls
Lock a starting frame, control camera motion (pan, zoom, tracking), and choose aspect ratio (16:9, 9:16, 1:1).

How it works

  1. 1
    Write a video prompt
    Describe subject, action, camera motion, and style. For best results include lighting and mood.
  2. 2
    Pick a model
    Sora 2 Pro for cinematic realism, Kling v3 Pro for human motion, Veo 3 for native audio, Runway Gen-4 for character consistency.
  3. 3
    Set duration and aspect ratio
    Choose 5 or 10 seconds, HD or 4K. Start with HD to iterate cheaply, then upgrade to 4K for the final shot.
  4. 4
    Generate and download
    Preview in-browser. Download MP4 or pass the output directly to the editor for further refinement.

Frequently asked questions

How long can AI text-to-video clips be?
Current frontier models generate 5 to 10 seconds per clip. For longer videos, chain clips using the same seed and prompt continuation — Oakgen's editor stitches them with smooth transitions.
How much does text-to-video cost per clip?
Costs range from ~$0.30 (Kling Turbo 5s HD) to ~$2 (Sora 2 Pro 10s 4K). A 5-second HD clip averages 50–200 credits on Oakgen. The $19/month Pro plan includes 5,000 credits — about 25–80 clips.
Does Veo 3 really generate audio too?
Yes. Veo 3 generates synchronized ambient audio and dialogue in the same pass as video — no separate audio step. It's the only model on Oakgen with this capability.
Can I keep the same character across multiple clips?
Yes — use Runway Gen-4 with a reference image, or Kling v3 with character locks. See our consistent characters feature page for the full workflow.
