How to edit short videos that people watch to the end

On TikTok, Reels and YouTube Shorts, the videos that spread are the ones people finish and watch again. You cannot control the algorithm, but you can edit for retention. Here is what to do, second by second.

The first second: stop the scroll

Viewers decide almost instantly whether to keep watching. Start with the most interesting moment, not an introduction.

• Open on movement, a surprising image or a bold statement.
• Put a short text hook on screen in the first frame.
• Cut "Hi guys, welcome back" entirely.

The middle: keep it moving

Cut every pause. Silence that feels natural in real life feels slow on a phone. Trim breaths and gaps between sentences. See cut dead air and tighten the pace.

Change the picture often. A new angle, a zoom, B-roll or a graphic every few seconds keeps the eye busy. See use B-roll to cover cuts.

Use captions. Many people watch with the sound off. Captions keep them following, and highlighting the spoken word helps the eye track. See highlight the spoken word in your captions.

Add sound design. A small whoosh on a cut or a pop on a text reveal makes edits feel intentional. See place sound effects on the beats.

The end: make them stay, or loop

• Deliver the payoff last. If your hook promised an answer, give it at the end.
• End cleanly. Stop as soon as the point lands. A long goodbye causes swipes.
• Try a loop. Make the last frame flow back into the first, so the video replays naturally.
• One call to action. Ask for one thing: follow, comment or watch part two. See end with one clear call to action.

Keep it short

Make the video as long as the idea needs and no longer. A tight 25-second video often outperforms a loose 60-second one. Watch your cut once at normal speed and remove anything you would skip as a viewer.

A quick retention checklist

• Does the first second show something interesting?
• Is there any pause longer than half a second?
• Does the picture change at least every few seconds?
• Are captions on and inside the safe area?
• Does the ending pay off the hook?

Let AI do the first pass

In DepCut, ask the AI assistant to "cut the silences and add captions". It listens to the audio, finds the dead air and builds the subtitles, and you review the result on the timeline.
