Tool by tool

Veo

The only tool here that generates dialogue and sound effects with the video. Korean speech sounds natural, making quick intro videos easy. Gemini subscribers pay no extra fee, though strict safety rules often block close-up faces, and videos carry watermarks.

Runway

Its real strength lies after generation. Built-in tools like background removal, outpainting, and stitching fit real-world live footage pipelines well. Image-to-video is reliable. The interface is English-only, and free one-time credits run out quickly.

Pika

Best for picking preset effects to churn out quick short clips. You don't need long prompts, making it ideal for social media memes and short promos. It isn't suited for long narratives, and low free credits with watermarks mean you'll hit limits fast.

Kling AI

Human motions like walking look natural, and daily credit refills offer the most free experimentation. It partially supports Korean UI. As a Chinese platform, check privacy terms and avoid uploading private faces or corporate assets. Queues can be long.

How to choose

First, decide if you need sound. Veo is the only option with built-in audio; others require external editing tools. Second is cost: Veo is free with a Google AI plan, while Kling's daily credits suit free trials. Third, choose Runway for heavy post-editing. All tools are foreign; domestic Korean tools like Vrew focus on editing, not generation. Check licensing for faces and assets.
