Lip sync, also called lip synchronization, matches a person or character’s mouth movements to spoken or sung audio. AI tools automate much of the frame-by-frame work, making it easier to replace dialogue, dub videos, animate characters, or create singing performances.

Q: Can I use my own voice?

Q: What kinds of characters can I lip sync?

How to Remove Background from Video

Upload Your Video

Start with the footage you already have in VIDEO 3.0 Omni. Your clip does not need to be recorded against a green screen before you change the background.

Delete or Replace Video Background

Tell Kling which subject should stay and which background you want removed. If a new setting is your real goal, skip the separate removal step: describe the background you want or add a reference image for Kling to follow.

Generate and Review

Generate the edit and check the subject and background throughout the clip. If something needs adjusting, refine the instruction and try another version, then save the result or continue editing in Kling AI.

Improve Video Resolution, Clarity, and Detail

Upscale Low-Resolution Video to 4K

Give footage with limited resolution more room to hold up on larger screens. Upload your clip, choose 4K output, and generate a higher-resolution version with clearer edges and more visible detail for viewing, editing, or final delivery.

Make Blurry or Soft Video Look Clearer

Soft footage can lose definition in faces, objects, edges, and backgrounds. Use Kling AI to generate a clearer version with stronger visual definition, whether you are working with an older clip, compressed footage, or a shot that simply looks too soft.

Bring Out More Texture and Fine Detail

See more definition in skin, fabric, product surfaces, landscapes, water, smoke, and other detailed parts of a scene. Instead of simply enlarging the existing pixels, VIDEO 3.0 Omni generates new visual detail as it creates the higher-resolution result.

Kling AI has made it easy for us to generate world class visuals for Fortune 500 companies, TV shows and music for big artists. We love the easy of use of the platform and the quality of the generations. My first time using Kling AI, I got 22 million views on just one video. It's that good.

I use Kling AI every day. It's amazing to see the almost daily progress it makes. I used AI for fun at first, and I now find that Kling AI's animations allow me to gain professional visibility, with three times more views on my animated posts than on my static posts.
