Veo 3 Prompt Generator

Free AI Prompt Generator

Transform simple ideas into detailed prompts for AI image and video generators. Powered by Gemini 3 as the prompt enhancer, with output tailored for Veo 3.1, Midjourney V7, GPT Image 1.5, and Nano Banana 2 (Gemini 3.1 Flash Image). Small enhancements make a big difference.

This tool helps you generate those bigfoot vlog or glass-cutting ASMR videos. Spend time learning prompt engineering (see guides below), but this should help newbies get started.

Recommended Workflow: Frame to Video

The best results come from a Frame to Video approach rather than Text to Video:

1. Generate a starting frame using Midjourney V7, GPT Image 1.5, or Nano Banana 2
2. Use that frame in Veo 3.1's Frame to Video mode
3. 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 performs best with a strong starting frame

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; scene extension up to ~148 seconds
• Significantly stronger prompt adherence and frame consistency over v3

Image Model Comparison

Feature	Midjourney V7	GPT Image 1.5	Nano Banana 2
Best For	Style, concept art, moodboards	Intent understanding, text in images	Text accuracy, character consistency
Quality	Highest artistic	Good, slightly "glossy" feel	Pro-tier quality at flash-tier speed
Text Rendering	Weak (keep to 5 words)	Near-perfect (3-20 words)	Greatly improved, not infallible
Prompt Adherence	Needs skill (parameters, weights)	Strongest (natural language)	Very strong (creative-brief style)
Learning Curve	Steep (V7 parameters)	Easy (natural language)	Easy (natural language)
Aspect Ratio	Any integer ratio (default 1:1)	3:2, 2:3, 1:1	14 ratios incl. extreme (1:8, 8:1)
Image Editing	Vary Region inpainting	Full edit/inpaint, up to 16 refs	Best (mask-free conversational, 4K)
Speed	Fast (Draft Mode 10x)	~10-30 seconds	4-8 seconds
Character Lock	Via --oref (1 image)	Character anchor workflow	Up to 14 reference images

If you're just starting out, Nano Banana 2 via Gemini or GPT Image 1.5 via ChatGPT both work well with natural language -- write like a creative director, not a search engine. For artistic work, Midjourney V7 offers the highest visual quality (expect a learning curve with its parameter system). For text-heavy or branded content, GPT Image 1.5 has the most reliable text rendering. Nano Banana 2 is the fastest and cheapest option with the strongest editing workflow (mask-free conversational edits, up to 14 reference images, and Google Image Search grounding for real-world accuracy).

This is why we built Generate with a frame in the tool. It handles prompt-engineering, initial frame + follow-up edits, and outputs 16:9.
