Specialists’ opinions vary when they discuss if an intro is needed and what information it should have. An introduction makes the author more recognizable, and viewers prefer to be familiar with the way material is presented. It is vital to be concise and not to exceed 15 seconds.
An intro can be:
The same for all videos. It will help the video to stand out and be more recognizable.
Different for different sections and even for different videos. It shows the overall style of the author and introduces the topic of the video.
The intro contributes to the recognition of the brand. If apart from being stylistic, it shows what a video is about, it gives viewers 10 seconds to decide whether to watch the video or not. A qualitative intro guarantees that the video will be watched until the end. Moreover, you can break your video into parts and add semantic stops.
