1. Exposure increased when length was reduced

Initially, to fill the content completely, I produced it with 40~50 seconds. However, the watch time (retention rate) hit rock bottom.

Change: Dramatic diet to the 15~28 second range

Result:Watch time exceeded 100%[span style="color: rgb(0, 0, As it started doing this, the algorithm began to explosively increase exposure, saying, "You're watching this video to the end?"

2. The power of tempo that doesn't give you a moment to take your eyes off it

Just as important as shortening the video length is editing tempo

Cut editing: Use screen switching or zoom in/out every 1~2 seconds. (Divide cuts as often as possible)

Speed: Cut out all unnecessary words or silences without allowing even 0.1 seconds.

Effects: The video must end before the viewer feels 'bored'. That way, it leads to rewatching.

3. The Essence of Shorts: 'Good Video' vs 'Video to Watch Until the End'

We sometimes try to do art. However, the Shorts algorithm is cold-hearted. Shorts selects videos that are objectively 'watched to the end' rather than videos that are subjectively 'good.' Videos with high completion rates ultimately win, even if the content seems a bit lacking.
