AI Prompts for YouTube Video Editing

1. The assembly prompt

Long-form wants a different treatment from short-form: a gentler pacing pass that preserves section breaks, restrained captions, and consistent audio. This request covers the whole finishing pass for a typical YouTube video and leaves the structural decisions to you.

The long-form finishing pass

"Tighten the pacing but keep the breathing room between sections, level my audio, and add captions in a clean broadcast style."

2. Fixing the opening

The opening is where long-form videos lose their audience, and it is usually fixable with a trim rather than a re-record. These prompts cut the run-up so the video starts on a promise instead of a greeting.

'Cut everything before my first real sentence.'
'Trim the pause before I start talking.'
'Cut the intro animation, start straight on the content.'
'Move the strongest line from the middle to the front.'
'Add a short text card in the first few seconds saying what this video covers.'

3. Through the body of the video

Long-form needs regular visual change rather than constant motion. These prompts add variation at a rate that suits a longer watch, and they favour showing things over decorating them.

'Add cutaways where I describe something the viewer should see.'
'Punch in slightly on my key claims, spaced out rather than frequent.'
'Speed up the section where nothing is happening on screen.'
'Add a section title at each chapter boundary.'
'Cut the part where I repeat the point about pricing.'

Tip

On long-form, a screenshot of the actual thing you are describing usually beats stock footage. Specific beats decorative.

4. Captions and chapters

Long-form captions want a different treatment from short-form ones: full lines rather than a couple of words, and a restrained style rather than a boxed one. Markers at section boundaries give you chapter points, which help both navigation and the viewer's sense of structure.

'Add captions in a clean white style, full lines rather than a few words.'
'Use a broadcast subtitle look rather than a social one.'
'Show a full line, two lines deep.'
'Add markers at each section boundary so I have chapters.'
'In the captions, replace the product name spelling everywhere.'

5. Repurposing prompts

The cheapest content you will make is the short-form cut from a long video you have already edited. These prompts take the finished long-form project and produce the vertical clips, without re-doing any of the work.

'Cut this into short clips for Shorts.'
'Find the moments that would work as standalone clips, with timestamps.'
'Make a 60-second highlight version of this.'
'Take the section about onboarding and make it a vertical clip.'
'Give me a square version for LinkedIn.'

Common Mistakes to Avoid

✖ Using short-form pacing on long-form

Why it fails: A gapless, jump-cut rhythm over ten minutes is exhausting and removes the section breaks that help viewers follow the structure.

✔ Better approach: Ask for the breathing room between sections to be kept.

✖ Using boxed viral caption styles on long-form

Why it fails: They belong to a different format and undercut the authority of a longer, more considered video.

✔ Better approach: Ask for a clean or broadcast caption style with full lines.

✖ Captioning before the cut is locked

Why it fails: Every later structural change shifts the caption timings.

✔ Better approach: Lock the structure first, then caption.

Frequently Asked Questions

Common questions around this editing workflow.

Full lines, one or two deep. The rapid word-by-word rhythm belongs to vertical short-form and feels frantic over a longer watch.
