Veo 3 Prompt Generator
Enhance your prompts
Transform basic prompts into detailed, effective instructions for AI image and video generators.
Free AI Prompt Generator
Transform simple ideas into detailed prompts for AI image and video generators. The prompt enhancer runs on Gemini 3.8 Flash (Claude Haiku on the free tier), with output tailored for Veo 3.1, Midjourney V8.2, GPT Image 2.5, and Nano Banana 2.1. Small enhancements make a big difference.
It's built for the bigfoot-vlog and glass-cutting-ASMR stuff. Learning prompt engineering yourself is still worth the time (guides below), but this gets you started.
Recommended Workflow: Frame to Video
The best results come from a Frame to Video approach rather than Text to Video:
- Generate a starting frame using Midjourney V8.2, GPT Image 2.5, or Nano Banana 2.1
- Use that frame in Veo 3.1's Frame to Video mode
- Iterate on images first, cheaper and faster than iterating on video
Why Frame to Video?
- Iterate on images faster and cheaper than videos
- Maintain character consistency through image edits
- Give Veo a clear visual reference to work from
- Veo 3.1 builds the whole clip on the starting frame, so a sharp, well-composed one pays off
Veo 3.1 Features:
- Native audio generation (dialogue, sound effects, ambient sounds)
- Image-to-video, first/last frame interpolation, and up to 3 asset reference images
- 4/6/8-second clips at up to 4K resolution; extend a clip 7 seconds at a time, up to 37 seconds
Image Model Comparison
| Feature | Midjourney V8.2 | GPT Image 2.5 | Nano Banana 2.1 |
|---|---|---|---|
| Best For | Style, concept art, moodboards | Intent understanding, text in images | Conversational editing, character consistency |
| Versions | V8.2 is the default | Flare (speed) or Sunburst (quality) | 2.1, or Nano Banana 2 Lite for speed and cost |
| Text Rendering | Short words in double quotes | Exact text in quotes; placement can still slip | Improved in 2.1; settle the text first |
| Prompting Style | Short, clear phrases plus parameters | Spec-style natural language | Full-sentence scene descriptions |
| Learning Curve | Moderate (parameters) | Easy (natural language) | Easy (natural language) |
| Aspect Ratio | Any integer ratio (default 1:1) | Custom sizes up to 3:1 | 14 ratios incl. extreme (1:8, 8:1) |
| Image Editing | See Midjourney's docs | Edits with masks and multiple reference images | Conversational edits, up to 14 reference images |
If you're just starting out, Nano Banana in Gemini or GPT Image in ChatGPT both work well with plain natural language: describe the scene in full sentences instead of stacking keywords. For artistic work, Midjourney V8.2 offers the highest visual quality, though its parameters take some learning. For text-heavy or branded content, GPT Image 2.5 renders exact text well when you quote it word for word. Nano Banana 2.1 has the most flexible editing workflow, with conversational edits, up to 14 reference images, and Google Image Search grounding for real-world subjects.
This is why I built Generate with a frame into the tool. It handles prompt-engineering, initial frame + follow-up edits, and outputs 16:9.

Video Generation
- Veo 3.1, best overall - native audio, image-to-video, first/last frame interpolation, 4K, scene extension
- Kling 3.0, native 4K with lip-synced audio, strong for character motion
- Runway Gen-4.5, best for experimentation and material rendering
Bringing It All Together
- CapCut, easy video editing, great for social media
- DaVinci Resolve, professional-grade, free, steeper learning curve
- Topaz, AI upscaling to 4K
