"I suddenly found that face-changing videos can be made for free.
Nowadays, many people on the Internet are looking for free artificial intelligence face-changing video production tools. In fact, such tools have really become more and more recently. Think about it, in the past, changing faces either spent money to buy software or the technical threshold was extremely high. But it's different now.
For example, many of the AI face-changing tools that have become popular recently have launched free versions. They make money through advertising or membership, but the basic functions are enough for ordinary people. I have tried an online tool called "FaceSwapper" before, which is completely free and easy to operate. You only need to upload photos of two faces, and it will automatically generate a face-changing effect.
However, it should be noted that free tools usually have restrictions on their use. For example, only a few pictures can be processed per day, or the video generated is not of high resolution. This is normal, after all, people also have to control costs. If you want a more advanced effect, you may still have to pay for it.
Let's talk about the needs on TikTok. Nowadays, many accounts are using face-changing videos to gain popularity. You must have seen videos where one person plays multiple roles while surfing TikTok. In fact, many of them are made using AI to change faces. For example, a person performs a dialogue, he is himself on the left, and the other person he is playing on the right. The audience thought there were really two people.
How to use these tools? Find the right platform first. There are two mainstream ones now: one is that requires downloading software, such as some mobile apps; the other is a web version, such as AI workflow tools such as Coze. The advantage of the web version is that it can be operated directly with the browser without installation.
The specific steps are actually very simple. For example, with a web version of the tool, you upload the original video first and then upload your photos. Then select the face change area, such as changing only the face but not the background. After the tool is processed, you can download the finished product. The whole process can be completed in a few minutes.
Of course, whether the effect is good depends on several factors. One is the clarity of your photos, and the other is the lighting conditions in the video. If the light is too dim or too bright, the face may be deformed. I suggest finding a video material with evenly lit light first and testing it with your own frontal view.
There is also a tip where you can try out more tools. For example, among the free tools,"DeepFaceLab" is difficult to use, but it works well;"Reface" is simple to operate and suitable for novices. You can pick an easy one to start with, and then switch to a more complex one when you become proficient.
However, pay attention to copyright issues. Some tools generate videos that may be watermarked and are not commercially available. If you plan to use it on TikTok, you'd better check the terms in advance. For example, some regulations can only be used for personal entertainment and cannot be used to make money.
I also noticed a trend recently. Many tools are beginning to support multiple people to change faces. In the past, only one person could change one face, but now you can change multiple faces at the same time. For example, in a video of a multi-person conversation, you can replace everyone with your own face. This gameplay is very popular on TikTok because viewers will find it very novel.
Let's talk about the technical principles. AI face changing actually consists of two steps: the first step is to extract facial features, and the second step is to synthesize new videos. Today's free tools package these steps, so you don't need to understand code to use them. But if you want to go deeper, you can learn some basics. For example, adjusting facial expressions to make face changes more natural.
A reminder, don't be superstitious about "completely free". Many tools use the banner of free, but quietly collect your data. For example, uploaded photos may be used to train AI models. If you care about privacy, try to use a well-known platform.
Overall, the free artificial intelligence face-changing video production tool is indeed convenient for ordinary people. But before using it, you should understand clearly the limitations, such as resolution, watermark, and terms of use. Try a few more tools to find the one that suits you best. This way, you can play new tricks without having to spend money wrong. "
