💡Face Swapping

Face swapping is a technique that involves replacing the face of a person in a photo or video with another face. In the context of the video, it refers to the process of using AI to change the facial features of an image while maintaining the original person's likeness, which is demonstrated by swapping faces between different images and scenes.

💡Input Image

The input image is the original photo or graphic that serves as the starting point for any image manipulation or editing process. In the video, selecting an input image is the first step in the face swapping process, where the user chooses a reference image to be used for the AI-generated output.

💡AI Generated Images

AI generated images are those created by artificial intelligence algorithms that can produce visual content based on given parameters or prompts. The video discusses the effectiveness of using AI images for face swapping, suggesting that they work best due to their compatibility with the AI tool's capabilities.

💡Advanced Options

Advanced options refer to the more complex settings and features within a software or tool that allow users to fine-tune their output. In the video, these options are accessed to modify the face swapping process, such as adjusting the 'stop at weight' to focus more on facial features.

💡Control Nets

Control nets are tools or settings within an AI image generation platform that help guide the output to match certain desired characteristics, such as pose or facial structure. In the video, control nets are used to ensure the generated images adopt the same pose as the reference image.

💡Reference Image

A reference image is a sample or template used as a guide for AI to base its output on. In the context of the video, the reference image is the image whose face or pose is to be replicated or swapped in the new images created by the AI.


In the context of AI image generation, weight refers to the influence or importance given to certain features or aspects of the input during the generation process. Adjusting the weight can affect how closely the AI's output resembles the input or reference image.


The background in image editing refers to the scene or setting that surrounds the main subject. In the video, changing the background involves altering the context of the image to create a new atmosphere or environment for the subject, such as from a street scene to a nature setting.

💡Real Photos

Real photos are images captured by a camera, as opposed to AI generated images. The video discusses the use of real photos in the face swapping process, noting that while they can be used, certain considerations and adjustments may be necessary to achieve satisfactory results.

💡Custom Models

Custom models in AI image generation are tailored algorithms that have been trained or adjusted to produce specific styles or outputs. The video mentions that custom models may have a default look that doesn't always match the reference image, suggesting the use of a base model for better results with real photos.


Styles in AI image generation refer to the aesthetic or visual characteristics that can be applied to the output. The video suggests experimenting with different styles to achieve the desired look, although it notes that the default styles often work well for the face swapping process.
