The process of including and maintaining a personalized image in a video using ffmpeg while continuously moving it involves the following steps:

1. Install ffmpeg: First, install ffmpeg on your system. You can follow the instructions from the official website to install the software.

2. Create the personalized image: Create the personalized image that you would like to include in your video. Ensure that the image has a transparent background, and it is in a format that ffmpeg can handle, such as PNG.

3. Define the video dimensions and length: Determine the dimensions of the final video and its length. This information will guide you when positioning and moving the personalized image in the video.

4. Use the ‘overlay’ filter: The overlay filter allows you to add the personalized image to the video. It positions the image on top of the video frame at a particular location.

5. Modify the position: To make the personalized image move continuously throughout the video, you will need to modify its position after every frame. Each frame has a timestamp that ffmpeg can use to determine the position of the image. You can write a script that will calculate the new position and modifies the overlay filter for each frame.

6. Preview and test: Once you have completed the above steps, preview the video to ensure that the personalized image moves smoothly through the video.

7. Save the video: Save the final video to your preferred format.

To maintain the personalized image’s quality, ensure that it does not get pixelated when it is moved or enlarged. You can achieve this by ensuring that the source image's resolution is high and that you adjust the overlay filter's parameters accordingly.
