Your video. A plan. Then the edit.

A prompt is simply an instruction: tell the tool what you have and what you want to achieve.

ChatGPT

Helps organize the idea and prepare an editing plan. Share a transcript if your setup cannot analyze the file.

Codex

Can help implement the plan using available files and processing tools. A written plan is not yet an edited video.

On your phone?

Tap Copy prompt and paste it into your conversation. Customize and prepare the plan; processing needs file access and a compatible environment.

On your computer?

Put the original in a folder, open the folder in Codex, and share the prompt. Ask it to check available tools before starting.

Do I need lots of software?

Do not start by installing everything. FFmpeg processes media, Python can connect tasks, and a transcription tool adds word timing. Ask Codex to check what is available and explain what is missing. Review the result in your usual editor.

01

Cut the extra pauses. Keep the human rhythm.

A thinking pause can drag. A pause that lets an idea land can help. They need different treatment.

↳Like removing extra gaps in a conversation without making someone sound breathless.

  1. 01

    Start by flagging pauses around 0.4–0.6 seconds, not automatically cutting them.

  2. 02

    Listen to each suggestion. Remove mistakes, repetitions, and pauses that stall the idea.

  3. 03

    Keep breaths, emphasis, and complete words. Check that lips and voice stay in sync.

Idea 01Long pause…Idea 02

Toggle “Trim pauses” to compare the rhythm. This drawing does not process your audio.

↳ Prompt: pauses
Read the instructions
Analyze my video audio and identify long pauses, mistakes, excessive filler words, and unnecessary repetitions. Propose cuts that improve pacing without cutting words, important breaths, or complete sentences. Keep audio and video synchronized. If processing tools are available, create an edited version. Otherwise, provide a timestamped cut list. Do not claim you edited a file if you only created a plan.
02

Give the eyes something new.

A visual change can be a closer crop, a phrase on screen, or a supporting image. Every word does not need an effect.

↳Imagine explaining something while pointing at a photo. Change the view when it helps your explanation.

  1. 01

    Try changes every three seconds or less only when they help. This is a style guideline, not an Instagram rule.

  2. 02

    Alternate the original shot, a moderate zoom, text, or B-roll you have permission to use.

  3. 03

    Match changes to important ideas. If a change distracts, return to the simple shot.

Play this ten-second sequence. See several ways to change the picture without changing the message.

↳ Prompt: rhythm
Read the instructions
Create a dynamic edit for Instagram Reels, TikTok, and YouTube Shorts. Add cuts or visual changes every three seconds or less when they add value. Alternate the original frame, moderate close-ups, highlighted text, and available supporting images. Sync changes with important phrases. Avoid repetitive movement or cuts that interrupt words or gestures.
03

Let your skin look like your skin.

Start with a natural picture, then choose a style. A heavy filter does not automatically fix dark or overly yellow footage.

↳Like adjusting a room’s lighting before taking a photo.

  1. 01

    Exposure: avoid an image so dark or bright that details disappear.

  2. 02

    White balance: correct unwanted yellow, green, or blue casts.

  3. 03

    Adjust contrast and saturation moderately. Compare cuts so your face does not change color.

Warm simulationNatural

Drag to compare a color simulation. Every recording needs its own adjustment.

What about RGB curves?

They offer more precise control of light, shadows, and colors. A gentle S can add contrast, but it does not suit every recording. Ask for a review before applying it. You do not need to draw a curve to use the prompt.

↳ Prompt: color
Read the instructions
Analyze the recording’s visual characteristics and propose professional color correction. Prioritize balanced exposure, correct white balance, natural skin tones, and moderate contrast. Use luminance and RGB curves when appropriate. Avoid excessive saturation, crushed shadows, and clipped highlights. Keep cuts visually consistent and avoid extreme adjustments that degrade the picture.
04

Move closer to underline an idea.

A gentle zoom starts without a jolt and ends without a sudden stop. It does not need to be dramatic to feel intentional.

↳Like leaning in slightly when you are about to say something important.

  1. 01

    Try a 105%–115% scale, adjusting for headroom and original quality.

  2. 02

    Define the start and end of the movement. Those points are called keyframes.

  3. 03

    Ask for a gentle start and finish. Bézier curves control acceleration and deceleration.

Gentle start → gentle finish

Move the slider. Watch the framing before requesting a larger zoom.

↳ Prompt: zoom
Read the instructions
Apply gentle zooms to the video’s most important phrases. Use keyframes with Bézier curves and gradual acceleration and deceleration. Start around 105%–115% scale, adapting to the framing. Avoid abrupt movement, unnecessary scale changes, and excessive quality loss. Keep the main subject properly framed throughout.
05

Smooth movement. Sharp text.

Motion blur is a short trail accompanying fast movement. It does not mean blurring the whole screen.

↳Like the trail of an object moving quickly past a camera.

  1. 01

    Use it on fast movement or a moving graphic.

  2. 02

    Match intensity to speed; slow movement may not need it.

  3. 03

    Keep faces, captions, and important information readable.

Try it here · visual example
This text stays readable.

Enable the graphic’s trail. The sample text stays still and readable.

↳ Prompt: motion
Read the instructions
Apply motion blur only to elements with significant movement. Match blur strength to each animation’s speed. Avoid blurring faces, subtitles, and information that must stay readable. Prioritize a natural appearance and preserve overall sharpness.
06

Most of the time, a good cut is enough.

A shot change does not need a spectacle. Use a transition to connect moments, not because the software has lots of effects.

↳Think of punctuation: a comma helps; twenty exclamation marks get tiring.

  1. 01

    Use direct cuts for most phrases and explanations.

  2. 02

    Use a short blur or zoom when a scene change calls for it.

  3. 03

    For some quick transitions, try 0.15–0.35 seconds as a starting reference. Adjust by watching and listening.

Try it here · visual example
Scene A

Choose a transition in the example. Compare the change without adding more elements.

↳ Prompt: transitions
Read the instructions
Use direct cuts as the main transition. When justified by the content, add brief blur or zoom transitions with smooth motion curves. Avoid excessive effects, unnecessary flashes, or transitions that distract from the message. Preserve visual continuity and audio synchronization.
07

Make it understandable even without sound.

Short phrases, good contrast, and correct words come first. Animation comes later. Captions can feel like part of your brand too.

↳Like a sign you can read at a glance.

  1. 01

    Use your font and two colors: one for reading and one for emphasis.

  2. 02

    Use short phrases and review names, spelling, and synchronization.

  3. 03

    Leave room for platform controls and avoid faces or important details. Review a phone preview.

Customize the colors and font below. The master prompt will use your choices.

↳ Prompt: captions
Read the instructions
Create subtitles synchronized with the original audio. Use [BRAND FONT], [MAIN COLOR], and [ACCENT COLOR]. Break subtitles into short, readable phrases. Highlight only words that add emphasis. Keep text within safe areas for Reels, TikTok, and YouTube Shorts. Do not place captions over faces or important information.

Now copy it and take it to Codex.

Here are all the instructions together. Change these settings and the prompt updates immediately.

Use contrasting colors and a font available in your editing environment. If it is missing, request an alternative before export.

↳ Master prompt · complete edit
Read the instructions
Act as a professional video editor for Instagram Reels, TikTok, and YouTube Shorts. Turn my original recording into a natural, dynamic, polished video without changing my meaning or adding unnecessary effects.

PROJECT
Video type: EDUCATIONAL
Format: vertical 9:16.
Main platform: Instagram.
Brand font: Arial.
Main color: #ffffff.
Accent color: #d5ae63.
Style: modern, clean, dynamic, professional.

1. REVIEW THE MATERIAL
Identify the main message, key phrases, mistakes, repetitions, and unnecessary pauses. If you cannot access the video or audio, request the file or a timestamped transcript. Do not invent observations.

2. CLEAN UP PAUSES
Start by flagging pauses around 0.4–0.6 seconds for review, adapting to the speaker and background noise. Remove only pauses that harm pacing. Preserve natural breaths, expressive pauses, complete words, and meaning.

3. BUILD THE RHYTHM
Add visual changes every three seconds or less only when useful. Alternate original framing, moderate zooms, and available supporting visuals. Match changes to the message, without cutting words or important gestures.

4. CORRECT THE COLOR
Review exposure, white balance, contrast, and saturation. Use luminance and RGB curves where appropriate. Keep natural skin tones and consistent cuts. Avoid excessive adjustments.

5. ADD GENTLE ZOOMS
Use keyframes with Bézier easing and a gradual start and stop. Try 105%–115% scale, adapting to framing and source resolution. Keep the subject properly framed.

6. USE MOTION BLUR SELECTIVELY
Match blur to motion speed. Keep static elements, faces, and captions readable.

7. KEEP TRANSITIONS SIMPLE
Favor direct cuts. Use short blur or zoom transitions only when they improve continuity. Avoid excessive effects.

8. CREATE CAPTIONS
Synchronize captions with the original audio. Use Arial, #ffffff, and #d5ae63. Keep phrases short, highlight meaningful words, and leave space for platform controls. Do not cover faces or important information. Check spelling and names.

9. REVIEW AUDIO
Keep the voice natural. Adjust levels as needed and reduce background noise without introducing artifacts. Avoid sudden volume changes between cuts.

10. EXPORT
Create an MP4, 1080 × 1920, 9:16, H.264 video with AAC audio. Preserve source frame rate when compatible. Check audiovisual synchronization and picture quality.

IMPLEMENTATION WITH CODEX
If you have the source file and a suitable execution environment, build a reproducible workflow with FFmpeg, Python, and additional tools as needed. Check dependencies before running and organize processing into stages. Keep the original untouched. Produce a final file and change log. If an operation cannot be implemented, explain the limitation and offer an alternative. Do not claim a video was edited if you only produced instructions or code.

Before processing the full recording, create a 15–30 second sample for review. Inspect the exported file, captions, synchronization, and audio before calling the edit finished.

EXPECTED RESULT
A natural, dynamic video consistent with my brand, ready for review before publication.
