Everyone can become a virtual idol! The popular AI character replacement model is revealed, capable of perfectly mimicking even voices

Recently, AI character replacement videos have been going viral on social media. Whether it’s the level of facial detail or the fluidity of body movements, they are astonishing everyone and making people wonder what is still real online. In the past, “Video-to-Video” technology like this often required high-end computers and complex coding, but now, with just a browser and many affordable or even free tools available on the market, it can be easily done. This article is based on the previous post on X with over 1.7 million views, the AI Character Replacement Tutorial Guide, introducing the most powerful AI video generation and recommendation models currently available, as well as key prompt techniques. Feel free to try it out.

Kling 2.6: 4 Steps to Create the Perfect AI Transformation Video

Currently, in the field of AI character replacement, Kling is undoubtedly the reigning champion. Especially with its latest version, Kling 2.6, which supports reference videos up to 30 seconds long and can handle quite complex body movements. Kling’s greatest strength lies in its “Camera Control (Motion Control),” allowing the AI-generated character to perfectly replicate the movement details from the reference video. To produce high-quality videos with Kling, you can follow these steps:

Find High-Quality Reference Material: A clear video featuring a single character, preferably showing the upper body or full body. The source can be your own footage or clips from YouTube, TikTok, etc.

Generate the First Image with AI: This is the most critical step. Capture the first frame of the reference video and input it into image generation tools (such as Nano Banana Pro or Flux 2 models on the Krea platform). Use prompts to modify the character or background as desired, but be sure to keep the original pose and composition. Example prompt: “Replace the man in the picture with a cyberpunk-style woman, maintaining the same pose.”

Upload to Kling for Synthesis: Upload the reference video and the newly generated first image to Kling’s official website. Usually, no additional prompts are needed, but be sure to check “Character orientation matches video” to ensure smooth motion continuity.

Post-Processing with ElevenLabs Voice: Kling retains the original video’s sound. However, if you change the character’s gender or age, you can use ElevenLabs’ voice changer, which can replace the voice while preserving the original tone and rhythm to match the new character.

the era of TRUE AI UGC has started

for the longest time AI clips felt sloppy, cheap and cringe

but now you can make high quality reactions in just a couple of seconds

just attach a 5 second demo and you’re good to go!

Advanced Users: Wan 2.2 Animate Dual-Mode Application Tips

Besides Kling, Wan 2.2 Animate is also a model worth paying attention to. Although it was released earlier, it still has strong capabilities in character replacement. When using Wan 2.2, avoid having extraneous clutter in the background of the first image, as this is crucial for the quality of the generated video. Additionally, it offers two core modes suitable for different creative needs:

Move Mode: Apply the character’s movements to a completely new scene (ideal for changing both the character and background simultaneously).

Replace Mode: Only replace the character in the video, keeping the background and scene unchanged.

Wan 2.2 Animate is CRAZY and it actually excels at 3 things from my tests:

1. Lip syncing (so far the best open source I have seen, beating Runway Act2) 2. Consistent lighting & shadows with color tone replication when you swap a character 3. It keeps the replacement character… pic.twitter.com/c8v2PeJoOd

Styling Creative First Choice: Luma Ray 3 and Runway Gen-4

If you have more diverse needs for video editing, Luma Ray 3 (using the Modify feature) and Runway Gen-4 (using the Aleph feature) are also good options. However, these two models generally have lower accuracy in “lip-sync,” and video length limits are stricter—10 seconds for Luma Ray and only 5 seconds for Runway.

However, if you don’t need extensive character dialogue and want to create short videos with strong style and stunning visual effects (such as turning real footage into anime style), these models offer excellent creative space and can even produce surreal visual experiences.

AI is About to Spark a Content Creation Revolution

The emergence of these AI tools signals an explosion of a film and television revolution. Scenes that previously required Hollywood-level special effects teams, millions in budget, and professional green screens can now be created by a single creative with just a browser. This means the power of storytelling is being decentralized. In the future, the quality of works will no longer depend on capital scale but on innovative ideas and extraordinary imagination.
