How to use AI for intelligent video synthesis

With the development of artificial intelligence technology, video synthesis is no longer limited to traditional editing methods. Through AI technology, we can achieve high-quality and efficient video synthesis in a short time. This technique not only saves time, but also greatly improves the quality and creativity of your videos.

1. Preparation work

First, you need to prepare several pieces of video material that you want to synthesize. These materials can be pictures from different scenes, or pictures from the same scene but with different elements. Making sure the style and tone are as consistent as possible between the footage will improve the composition. In addition, you will need a computer or workstation capable of processing video, as well as enough storage space to save the original footage and the final product.

2. Choose the right software

There are many excellent video synthesis software on the market, such as Adobe After Effects and DaVinci Resolve. These softwares all provide powerful functions that can help users achieve complex video synthesis effects. Among them, DaVinci Resolve is favored by many people because of its powerful functions and ease of use in the free version. It supports a variety of video formats and provides a wealth of color correction tools to help users adjust video colors to achieve better blending effects. In addition, it has a powerful keying function that can easily separate the foreground from the background for easy post-processing. For beginners, the learning curve of this software is relatively flat and easy to get started.

3. Import materials and set up projects

After selecting the appropriate software, open the software and create a new project. Then, import the prepared video footage into the project. When importing materials, you can simply preview and check the materials according to the actual situation to ensure that all materials are as expected. Next, create a new composition layer according to actual needs for subsequent operations. In this way, the overlay sequence and effects of each material layer can be easily managed and controlled.

4. Application of AI synthesis technology

After importing materials and setting up the project, you can start applying AI synthesis technology. It is recommended to use some artificial intelligence plug-ins or scripts specifically designed for video synthesis. For example, the “Roto Brush” tool in Adobe After Effects is an AI-based keying technology that can automatically identify object boundaries in images to achieve precise keying effects. DaVinci Resolve also has some built-in similar tools, such as the "Ultra Key" and "Mocha AE" plug-ins. These tools can help users quickly separate foreground objects from the background, laying the foundation for the next step. In addition to the tools mentioned above, there are also some third-party plug-ins and scripts that can achieve similar effects. For example, Topaz Labs’ “Video AI” plug-in can complete complex video synthesis tasks in a short time. By using these plug-ins, you can further improve your work efficiency and achieve better composition effects.

5. Adjust details and improve effects

After completing the preliminary synthesis work, the details still need to be adjusted and improved. This includes adjusting parameters such as color, contrast, brightness, etc. to make the combined video look more natural and harmonious. In addition, you can add transition effects, text annotations and other elements to make the video more enjoyable and informative. In order to have better control over the composition effect, it is recommended to gradually adjust the parameters and preview the results in real time until you are satisfied. This not only ensures the quality of the final work, but also improves work efficiency.

6. Export and share

The final step is to export the combined video file. Choose the appropriate output format and resolution based on the requirements of the target platform. Generally speaking, common formats include MP4 and AVI. At the same time, be careful not to make the file size too large to avoid affecting the transfer speed. After exporting, you can share the video with friends or post it on social media so that more people can appreciate your creation.

In short, through the reasonable use of AI technology, we can easily achieve high-quality video synthesis. Whether you are a professional film and television producer or an amateur, you can use these advanced tools to improve your creative skills.
