Best Tool For You

The Decision Framework

Use Runway Gen 4.5 if:

  • You need fast, reliable results without audio
  • You're creating product demos, motion graphics, or abstract concepts
  • You value a clean, simple interface over advanced features

Use Sora 2 if:

  • You need realistic people with natural dialogue
  • You're creating testimonial-style videos or talking head content
  • You're already paying for ChatGPT Plus anyway
  • You prioritize human motion and lip-syncing over scenery/effects

Free Prompts

5 Universal Prompts That Work Across All Platforms

These prompts were tested across Runway, Kling, Veo, and Sora. Copy, customize, and paste.

Best for: E-commerce, product launches, unboxing content

Close-up shot: [SUBJECT] picks up [PRODUCT] from a minimal workspace and examines it closely. Shallow depth of field. Slow, deliberate motion. Soft natural lighting from the window. The background remains slightly out of focus. [DURATION: 5-8 seconds]

Best for: Testimonials, thought leadership, explainer videos

Medium shot of [PERSON DESCRIPTION] speaking confidently to camera in a modern [OFFICE/STUDIO]. Framed at chest height with subtle background blur. Natural, conversational tone. Dialogue: "[YOUR MESSAGE HERE]." Professional lighting, cinematic depth. [DURATION: 8-10 seconds]

Best for: Background footage, transitions, brand storytelling

Cinematic establishing shot of [LOCATION] at [TIME OF DAY]. Camera movement: slow pan from left to right. Mood: [EMOTIONAL TONE - inspiring/calm/energetic]. Lighting: [golden hour/overcast/dramatic shadows]. No dialogue, ambient sounds only. [DURATION: 5-8 seconds]

Best for: Instagram Reels, TikTok, YouTube Shorts

Fast-paced montage: [SUBJECT] performing [ACTION 1], then [ACTION 2], then [ACTION 3]. Dynamic camera angles with quick cuts. Energetic mood with upbeat background music. Bold, eye-catching visuals designed to stop the scroll. [DURATION: 5 seconds]

Best for: Explainer videos, SaaS demos, brand mood pieces

Abstract visualization of [CONCEPT]: [VISUAL METAPHOR]. Smooth, flowing motion with [COLOR PALETTE]. Camera slowly rotates around the central element. Dreamy, ethereal mood. Minimal background, focus on the main subject. Ambient electronic music. [DURATION: 8 seconds]

Tips

Pro Tips from Real Testing

Every test showed better results when starting from a Mid Journey or DALL-E image vs. text-only prompts. Why? The AI has a concrete visual reference instead of interpreting from scratch.

Quick workflow:

  • Generate image in Mid Journey ($10/month)
  • Upload to Kling ($9/month)
  • Total cost: $19/month for superior results

Don't wing it. Use this ChatGPT prompt to generate detailed video prompts:

You're a world-class cinematographer. Generate a detailed video prompt for me. Include: scene details, lighting, camera angle, motion, mood, and audio. The video should be about: [YOUR CONCEPT]. Make it specific enough for an AI video tool to generate a professional result.

This one trick improved our results by 40%.

 

Our "create an ad for a meal prepping business" test proved this. The more specific you are, the better the output. Compare:

❌ Vague: "A woman cooking"

✅ Specific: "A woman in her 30s, wearing a casual sweater, chopping vegetables in a bright modern kitchen with marble countertops. Natural afternoon light through large windows. Camera slowly dollies in from medium to close-up shot. Calm, aspirational mood."

Kling and Veo generate audio, but it's not perfect. Expect:

  • Slightly robotic voices
  • Unnatural background sounds
  • Dialogue that doesn't always match prompts exactly

Solution: Use ElevenLabs ($5-11/month) to replace AI-generated dialogue with higher-quality voices.

All four tools struggle with:

  • Aspect ratio changes (they won't switch 9:16 to 16:9 mid-generation)
  • Complex physics (objects morphing, melting cheese not melting correctly)
  • Hands and fingers (still the Achilles heel of AI)
  • Maintaining consistency across longer sequences

Don't expect perfection. Expect 80% there, with 20% cleanup in a tool like Canva Video Editor or CapCut.

Hot take

The Honest Truth About AI Video

Here's what the tests really showed: No AI video tool is perfect yet.

Runway is solid but pricey. Kling is affordable but quirky. Veo is gorgeous but expensive. Sora excels at people but struggles with everything else.

The competitive landscape shifts weekly. Don't lock into one ecosystem. Build workflows that work across multiple models. Test, iterate, and stay flexible.

Most importantly: AI video isn't about replacing videographers—it's about managing expectations, prompting with precision, and knowing when generating a video is smarter than producing one.

For most marketers and small businesses in 2026, that means Kling Video O1 at $10/month is your best bet. Start there, learn the ropes, upgrade when you need to.
