However, the demonstration has also raised concerns that largely mirror ones related to deepfake technologies - namely, the potential for exploiting such technologies to produce inauthentic content.Īrtificial intelligence technology is advancing at a clipped rate and, in many cases, can be used to imperceptibly alter videos and images. The technology could usher in an era of clearer, more consistent video conferencing experiences, particularly for those on slow Internet connections, while using less data than current options. However, NVIDIA's real-time AI-based video compression takes things to a new level by using AI to not only generate the subject in real time, but also modify them in convenient ways, such as aligning their face with a virtual front-facing camera. The use of artificial intelligence to modify videos isn't new most major video conferencing apps now include the option of replacing one's real-life background with a different one, including intelligent AI-based background blurring. Similar technology is already on the market in the form of Apple's AI-based Animoji. Likewise, the keypoints extracted from the subject's face could also be used to apply their movements to other characters, including fully animated characters, expanding beyond the AI-powered filters that have become popular some video apps like Snapchat. One example is Free View, a feature in which the AI platform can rotate the subject so that they appear to be facing the recipient even when, in reality, their camera is positioned off to the side and they appear to be staring into the distance. There are some other advantages to using AI-based compression that exceed the capabilities of traditional video technologies, as well. The AI technology then reconstructs the subject's face and animates it in real time using the keypoint data, the end result being very low bandwidth usage compared to the image quality on the receiver's end. ![]() This is made possible by extracting the key facial points on the subject's face, such as the position of the eyes and mouth, then sending that data to the recipient. With the traditional video compression, the resulting low-bandwidth video is very pixelated and blocky, but the AI-compressed video is smooth and relatively clear. In a video explaining the technology, researchers demonstrate their AI-based video compression alongside H.264 compression with both videos limited to the same low bandwidth. For users, this could result in what NVIDIA calls a 'smoother' experience that uses up less mobile data. According to the researchers, using AI-based video compression can strip video bandwidth usage down to 1/10th of the bandwidth that would otherwise be used by the common H.264 video codec. Select the “Start Encode” button (“Start” on a Mac) to finish the process.The new technology is made possible using NVIDIA Maxine, a cloud-AI video streaming platform for developers.Edit the file name and desired destination in the Save As area at the bottom of the screen.Once the video is open, you can select the “Very fast 720p30” under the Preset>General menu.If you are working on a Mac, the Open Source button will open the file selection menu where you can navigate and select the desired files. If your refer, you can also select the “File” button, and find the desired video to add to you project. Windows PC: Once you open HandBrake, you may need to click on the “Open Source” button or just start by drag and drop the file or files you want to compress.Once you have completed its installation, follow these steps to compress your video: ![]() ![]() An open source alternative for this is HandBrake and you can freely download it from their website. Sometimes, all you need is to decrease your video’s file size.
