Tik Tok's 5-second playback rate is above 30%. This ratio reflects the ability of the video to attract viewers to continue watching in the first 5 seconds. If the playback rate exceeds 50% within 5 seconds, the video is more likely to enter the hot list. However, for a very short video (say, 5 seconds), the interpretation of the broadcast completion rate may need special consideration, because the extremely short video content will be watched soon, so even a very low broadcast completion rate may reflect the audience's interest to some extent. To improve the broadcast completion rate of Tik Tok, you can try the following methods:

1, create an attractive opening: the first few seconds of the video determine whether the audience will continue watching, so the opening should be attractive enough. You can attract the audience with interesting or eye-catching pictures, music or subtitles.

2. Provide valuable content: ensure that the video content has certain uniqueness or characteristics, can arouse the interest of the audience, and provide some valuable information, tutorials or entertainment content. This way, viewers will be more willing to watch the whole video.

3. Control the duration of video: The duration of vibrato video is generally short, usually from tens of seconds to one minute. Make sure the video is not too long, lest the audience lose patience. Proper control of video duration can increase the possibility of viewers watching the whole video.

4. Use attractive thumbnails: Thumbnails of vibrato videos are displayed on the display page, which is one of the important factors for viewers to click and watch. Using attractive pictures related to video content as thumbnails can attract more viewers to click and watch the whole video.

5. Interact with the audience: guide the audience to interact in the video, such as asking them to leave a message, like, share or participate in some challenging activities. This can increase the audience's sense of participation and make them more willing to watch the whole video.

6. Use promotion: use Tik Tok's advertising promotion service to push the video to more target audiences. By positioning the advertising crowd and accurately selecting the push position, the viewing rate and the viewing rate of the video can be improved.

7. Continuous improvement: According to audience feedback and data analysis, continuously improve video production and content, meet audience needs and interests, and improve broadcast rate.
