The complete prompt guide for Veo, Nano Image, GPT Image 2 and Kling — learn how to write prompts that produce viral-ready videos and stunning images.
How Veo Prompts Work
Πώς λειτουργούν τα Veo prompts
Veo transforms your text prompts (and optional images) into short AI-generated videos. Think of it as directing a professional film crew — the clearer and more cinematic your instructions, the better the result.
The 5-Part Veo Prompt Formula
Η 5-μερής φόρμουλα Veo prompt
- Subject — What is in the video? (“a luxury car”, “a girl walking”, “a futuristic city”)
- Action — What happens? (“transforms”, “flies across”, “emerges from water”)
- Style & Atmosphere — How should it look? (“cinematic lighting”, “neon cyberpunk”, “sunset mood”)
- Camera & Movement — From which angle? (“smooth zoom-in”, “drone shot”, “rotating around subject”)
- Transitions — Any morphs or changes? (“logo morphs into smartphone”, “scene fades to night sky”)
Best Practices
Βέλτιστες πρακτικές
- ✅ Keep prompts 1–3 sentences — concise but visually detailed.
- ✅ Use visual adjectives: cinematic, glowing, realistic, dramatic, neon, glossy, soft lighting.
- ✅ Always specify movement: zoom, pan, rotate, fly-through, morph.
- ✅ For logo videos: describe the full transformation arc (logo → product → logo).
- ✅ Upload your logo as a 1280×720 PNG with transparent or solid background for best consistency.
- ⚠️ Avoid trademarks — movie characters, cartoon heroes, big brand logos. Google’s safety filters may block these.
Viral Prompt Examples
Παραδείγματα viral prompts
- “Transform the Campanior logo into a futuristic smartphone, then into a laptop, then a desktop computer, and smoothly back into the logo. Ultra-realistic, cinematic lighting, seamless morphing transitions.”
- “The logo emerges from glowing particles, transforms into the word ‘AMAZING’ in 3D neon lights, then collapses back into the logo. Dark background, professional studio lighting, smooth reflections.”

How Nano Image Prompts Work
Πώς λειτουργούν τα Nano prompts
Nano generates high-quality images at speed via Banana’s model. It excels at photorealistic renders, product shots, concept art and social media visuals. Images are stored in your personal library and loaded on demand to keep things fast.

How GPT Image 2 Prompts Work
Πώς λειτουργούν τα GPT Image 2 prompts
GPT Image 2 by OpenAI produces photorealistic and creative images with remarkable prompt adherence. It understands natural language well — you can write conversationally and it will follow instructions closely. It also returns a revised prompt showing exactly how it interpreted your request.
Choosing the Right Quality Tier
Επιλογή σωστού επιπέδου ποιότητας
- High — Use for final deliverables: hero images, ads, client work. Maximum detail, best colour accuracy.
- Medium — Use for social posts, blog headers, internal presentations. Great balance of quality and speed.
- Low — Use for rapid ideation, mood boards and concept exploration. Fast and cost-effective.
Writing Great GPT Image 2 Prompts
Πώς να γράφεις εξαιρετικά GPT Image 2 prompts
- Be descriptive in plain language — GPT Image 2 understands context well. “A cosy coffee shop in Paris, rainy day, warm light, film photograph” works perfectly.
- Specify the medium — “oil painting”, “digital illustration”, “studio photograph”, “3D render”, “watercolour sketch”.
- Include composition cues — “centred composition”, “rule of thirds”, “portrait orientation”, “wide panoramic landscape”.
- Use the revised prompt — check how GPT Image 2 reinterpreted your request. If it added or changed something useful, incorporate it into your next prompt.
Prompt Examples
Παραδείγματα prompts για καλύτερη κατανοήσή σας
- “A modern SaaS dashboard UI on a laptop screen, sitting on a minimalist white desk with a plant and coffee cup. Soft natural light, clean tech aesthetic, lifestyle photography.”
- “Professional headshot of a confident businesswoman in her 30s, standing in a bright modern office, warm smile, shallow depth of field, Canon 85mm lens aesthetic.”
- “An abstract digital painting of ocean waves at sunset, bold brushstrokes, deep navy and gold colour palette, gallery-quality contemporary art.”
- “Vintage travel poster of Santorini, Greece, in 1950s illustrated style, bold flat colours, bold typography, nostalgic and romantic.”
How Kling Prompts Work
Πώς λειτουργούν τα Kling prompts
Kling by Kuaishou is known for exceptional motion coherence and natural movement. It handles complex physics-based motion (water, cloth, hair, fire) better than most models, and produces very smooth, realistic video with consistent characters.
Choosing Your Kling Version & Mode
Επιλογή έκδοσης Kling & mode
- Standard mode — Faster generation, lower cost. Good for drafts, social media posts, quick iterations.
- Professional mode — Higher quality, more compute. Use for final deliverables, commercial content, client work.
- Variant selection — Different model versions offer trade-offs in speed, quality and realism. Experiment to find the best fit for your use case.
Kling Prompt Formula — Emphasise Motion
Φόρμουλα Kling prompt — Έμφαση στην κίνηση
- Character & Scene — Who or what is in frame? (“a woman in a white dress”, “a medieval knight”, “a futuristic cityscape at night”)
- Motion type — Kling excels here. Be very specific: “hair flowing in the wind”, “cloth rippling”, “water splashing in slow motion”.
- Camera work — “slow dolly forward”, “cinematic tracking shot”, “steady handheld”, “pull-back reveal”.
- Lighting & mood — “warm golden hour”, “cool blue moonlight”, “dramatic chiaroscuro”, “overcast diffused light”.
- Duration context — Describe what should happen over the clip’s length. Longer durations need a clear narrative arc.
Best Practices for Kling
Βέλτιστες πρακτικές για Kling
- ✅ Lean into physics — describe elements that involve natural movement: fire, smoke, water, wind, fabric, hair. Kling renders these beautifully.
- ✅ Consistent characters — Kling maintains facial and costume consistency better than many models. Describe characters in detail for repeatable results.
- ✅ For shorter clips, front-load the action: tell Kling what happens in the first 2 seconds explicitly.
- ✅ Use aspect ratio to match your platform: 9:16 for TikTok/Reels, 16:9 for YouTube/ads, 1:1 for Instagram feed.
- ✅ Generate at Standard mode first to validate your concept, then upgrade to Professional for the final version.
Prompt Examples
Παραδείγματα prompts για καλύτερη κατανοήσή σας
- “A woman in a flowing white silk dress walks slowly through a lavender field at golden hour, fabric and hair gently moving in the breeze. Cinematic tracking shot from behind, warm sunlight, shallow depth of field.”
- “Massive ocean waves crash against sea rocks in slow motion, water droplets and mist catching the morning light. Dramatic wide-angle shot, overcast sky, powerful and awe-inspiring.”
- “A lone astronaut walks on a red desert planet at dusk, two moons visible in the sky, dust swirling around their boots. Epic pull-back reveal, Hans Zimmer cinematic score atmosphere.”
- “A chef in a professional kitchen flips a pan of flambéed seafood, blue flames rising dramatically, sparks flying. Slow motion close-up, warm dramatic kitchen lighting, professional cooking video aesthetic.”
Rules That Apply Everywhere
Κανόνες που ισχύουν παντού
- 🔁 Iterate — Your first generation is rarely your best. Adjust one variable at a time (lighting, style, action) to systematically improve results.
- 💾 Save great prompts — All your generations are saved in your library. When a prompt works, document it and reuse for brand consistency.
- 🎯 Match the model to the task — Veo for brand/logo motion, Kling for natural character motion, GPT Image 2 for complex image briefs, Nano for fast product and social visuals.
- ⚠️ Trademark caution — Avoid famous movie characters, cartoon heroes, sports team logos and big brand identities. AI safety filters may reject these regardless of platform.
- 📱 Think platform first — Choose aspect ratio before generating. 9:16 for TikTok/Reels, 16:9 for YouTube/ads, 1:1 for Instagram feed, 4:5 for Facebook.
