Video opening credits are usually designed to guide the viewer through the theme and content of the video. First, determine the theme and purpose of your video. This helps create interesting and engaging subtitles. Next, choose the appropriate font, color, and size. You can use video editing software (e.g., Adobe Premiere, Final Cut Pro, etc.) to create subtitles, or you can use online tools (e.g., Kapwing, Veed, etc.) to accomplish this task easily. As shown here:

In subtitle design, it's important to keep things simple and easy to read. Avoid overly complex fonts and make sure colors contrast with the background to improve readability. Animations and transitions can add visual appeal, but don't overuse them. In addition, appropriate music and sound effects can also enhance the visual experience. In the image below, the video background is predominantly black and gray, and the subtitles have also been chosen in black to achieve unity of style.

In short, creating engaging opening credits for your video requires clarifying the subject matter, choosing the right fonts and colors, keeping the design simple and easy to read, and using animation and sound effects appropriately. Use the right tools and keep experimenting and improving, and you'll be able to create memorable opening credits for your videos.
