Many creators and general users want to perform advanced image editing and video production, but professional software is difficult to operate and time-consuming to learn.
AI image and video editing tools are now spreading explosively among those with such concerns.

Among them, “Remaker AI” has established a unique position due to its ease of use—running entirely in the browser—and its high precision in specialized functions like “face swapping” and “video generation.”

In this article, we will thoroughly explain how to use Remaker AI, from detailed setting methods for each function to tips for achieving high-quality results while saving credits, and even how to utilize “AI image editing.”

What is Remaker AI? A Multi-functional Creative Tool Accessible Just by Registering an Account

Remaker AI is a cloud-based AI platform that can be used simply by accessing it from a browser like Google Chrome or Safari, without needing to install special software or own a high-spec gaming PC (with a GPU).

The biggest feature is that “multiple powerful AI tools are aggregated on a single site.”
Usually, you would need to use this app for face swapping and that site for video generation, but with Remaker AI, everything is completed in one stop.

List of Major Features Included

1. Face Swap
   
   A function that naturally replaces the face of a person in a photo or video with another specified face. It supports not only still images but also videos.
2. Image to Video
   
   A function where the AI predicts movement and changes based on a single still image to generate a short movie. “Live Portrait” etc. are also included here.
3. AI Image Upscaler
   
   A function that enhances the quality and enlarges low-resolution images or out-of-focus photos while restoring details.
4. Background Remover
   
   A function that instantly recognizes subjects such as people, products, and animals, and makes the background transparent in an instant.
5. AI Photo Editor
   
   A comprehensive editing function for deleting unnecessary items in an image (Eraser) or drawing in missing parts (Outpainting).

Credits and Pricing Structure

To use Remaker AI, you need “credits.”
Upon account registration (you can log in with a Google account, etc.), 30 credits (free portion) are granted. With just this free portion, you can try face swapping several to a dozen times.

Credit Consumption for Each Function

The amount of credits consumed varies depending on the function and settings (high-quality mode, video length, etc.).
Since the “number of credits consumed” is displayed near the execution button each time, be sure to check before generating.

Paid Plans are Primarily “Pay-as-you-go”

While many AI services adopt a monthly subscription model costing several thousand yen, a major advantage of Remaker AI is that you can choose a prepaid method to “buy only what you need when you need it.”

• $2.99 (approx. 450 yen) for 150 credits
• $19.99 (approx. 3,000 yen) for 1,100 credits

Because you can pay in small amounts like this, it’s ideal for spot usage, such as “wanting to create a large number of images just this weekend.” Of course, there are also monthly VIP plans for frequent users.

1. Face Swap Thorough Explanation: From Still Images to Video

Remaker AI’s flagship feature, “Face Swap.”
Beyond simply pasting a face, the AI performs advanced calculations for lighting, skin tone, face orientation, etc., to synthesize them surprisingly naturally.

[Basic] Swap Face (Single Face Exchange)

This is the most basic one-to-one face swap. You can put your own face on a model’s photo or make historical figures look modern.

[Applied] Multiple Face Swap

Used when multiple people are in the image, such as group photos or couple photos.

1. When you upload an image, the AI automatically recognizes all faces in the image and lists them.
2. A plus button to select the “Target Face” appears under each recognized face.
3. Specify the target image only for the faces you want to change. Faces not specified will remain as they are.

This allows for advanced editing, such as “changing only the faces of the bride and groom to yourselves in a wedding group photo.”

[Advanced] Video Face Swap

A function to replace the faces of people in a video rather than a still image. It’s a very powerful feature for YouTubers and TikTokers, but there are points to note.

• Processing Time: Since it processes each frame of the video one by one, it takes longer to generate than a still image.

2. Image to Video Thorough Explanation: Prompts are the Key

A function that creates movements such as hair fluttering in the wind, flowing clouds, and blinking from a single still image. It is very useful as material for commercial production and short social media videos.

Operation Interface and Settings

Prompt Strategy: Syntax for Creating Videos Exactly as You Want

Here are tips for prompts to give accurate instructions to the AI. Try entering them in English by combining the following elements.

[Subject] + [Action] + [Environment/Background] + [Camera Work]
Example: A beautiful woman, [smiling and blinking], [wind blowing her hair], [cherry blossoms falling in background], [slow zoom in camera]

• Subject: A cat, A car, A cyberpunk city, etc.
• Action: walking, running, crying, laughing, etc.
• Environment: rain, snow, sunny, neon lights, etc.
• Camera: zoom in, pan right, static shot, etc.

3. Other Useful Tools: Background Removal, Upscaling, AI Editing

These tools may not be flashy, but they dramatically improve daily work efficiency.

Background Remover

Ideal for creating product images for e-commerce sites or cutting out people for YouTube thumbnails. Just “Upload” and wait a few seconds to download a transparent PNG image.
