# Thumbnail Layout Brief Prompt for Designers

A reusable prompt that turns a video topic and title into three distinct thumbnail layout briefs with text-slot and safe-area rules.

## Start here

Paste your video topic (one or two sentences) and the exact candidate title into an ordinary AI chat that accepts text. Add anything optional you already have: audience, platform, aspect ratio, forbidden elements, brand colours, or a plain description of a photo or person the thumbnail may use.

Then paste the complete prompt appended below. The model should first restate your topic and title, then list missing inputs, then give three layouts and a comparison line. If the topic or title is missing, it should stop and ask for both.

Check the output by confirming each of these:

- Every title word in every layout matches your words, in order, with nothing added or cut.
- The three directions differ in composition and focal point, not only colour.
- Each text block sits inside the stated safe area.
- No statistic, colour, number or brand appears that you did not supply, unless it is clearly labelled an assumption.

## What this prompt does

It produces a written creative brief, not an image. Each of the three layouts names a direction, describes canvas and safe area, focal element with an approximate grid position, background layers, exact text placement, a hierarchy note, and two risks with quick fixes. A short comparison line then says which layout suits which mood or platform.

Fictional example of the output shape (not a real test): for topic "a beginner guide to making cold-brew coffee at home" and title "Cold Brew, No Fuss," one direction might centre a glass jug with the title as two short lines bottom-left, while another splits the frame into a photo half and a flat colour block holding the full title.

## Inputs and permissions

What you must supply:

| Input | Needed? |
| --- | --- |
| Video topic | Required |
| Exact title words | Required |
| Audience, platform, aspect ratio | Optional |
| Forbidden elements, brand colours | Optional |
| Description of photo or person | Optional |

If no platform or aspect ratio is given, the prompt should offer two common options and label which layout fits each instead of assuming one. The prompt is a text-only instruction for a person to execute; it should not claim it created an image, opened an editor, exported a file or posted anything, and it should not claim a design was tested with viewers.

## Privacy and limitations

Anything you paste goes to whichever chat service you use, so avoid pasting confidential brand assets, unreleased product details or personal data you would not share there. The output is a starting brief for a human designer, not a finished thumbnail, and it will not verify legibility in practice.

This guide describes documented setup for the prompt. Source reviewed; runtime not tested.

## FAQ

**Do I need any software or account setup?**
No. Paste the prompt into an ordinary AI chat that accepts text. No terminal or API setup is involved.

**What if I only have a rough title?**
The prompt keeps the exact words you supply and does not rewrite them, so decide the final wording first. If the prompt splits a long title across lines, it must keep every word in order.

## Complete reusable prompt

You are helping me brief a graphic designer for a video thumbnail. I will give you a subject and a candidate title. Work only from what I supply. Do not invent product names, logos, statistics, faces, brand colours or claims that I have not stated.

INPUT I WILL PROVIDE
- Video topic: one or two sentences describing what the video covers.
- Candidate title: the exact title text, or the words that must appear in the image.
- Optional: audience, platform, aspect ratio, forbidden elements, brand colours.
- Optional: a plain description of any photo or person the thumbnail may use.

YOUR TASK
Produce three clearly different thumbnail layout briefs for the SAME topic and title, so the designer can choose a direction. Vary composition, focal point and how the text sits, not just the colour mood. Each brief must be a complete instruction a designer could follow without seeing the video.

OUTPUT FORMAT
For each of the three layouts, use this structure:
1. Direction name and one-line intent.
2. Canvas and safe area: state the aspect ratio you were given, or ask for it; describe where the crop-safe zone sits and keep all text inside it.
3. Focal element: what the eye lands on first, described in words (subject, object, scene), with its approximate position using a simple grid or fractions.
4. Background and depth: describe layers from back to front. No invented photos after I have named none.
5. Text placement: exact title words, the block they occupy, alignment, and whether the title is the main or secondary element. If the title is long, say how to split it across lines and keep the wording unchanged.
6. Hierarchy note: one sentence on what the viewer reads first, second and third.
7. Two risks: one legibility risk and one credibility risk for this direction, each with a quick fix.
Then add a short comparison line saying which layout suits which mood or platform, based only on the directions you wrote.

RULES
- Do not rewrite, shorten or embellish my title. Keep the exact words.
- Do not add numbers, awards, prices or comparisons unless I supplied them.
- Do not name any software, template pack or platform feature.
- If I have not given a platform or aspect ratio, offer two common options and label which layout fits each, rather than assuming one.
- If my title has more than six words, propose the line breaks you would use and keep every word.
- Keep the whole answer readable, not padded.

UNCERTAINTY AND MISSING INPUT
Before the three layouts, list any missing inputs that would change your placement or hierarchy. If the topic or title is absent, stop and ask for both rather than guessing. If you are unsure whether a described element suits the audience, mark it as an assumption.

CHECKS BEFORE YOU FINISH
- Every title word in each layout matches the words I gave, in order.
- Each of the three directions differs in at least composition and focal point.
- Every text block sits inside the stated safe area.
- No element, statistic or colour appears that I did not supply or that you did not clearly label as an assumption.

BOUNDARIES
This is a written creative brief only. Do not claim you created an image, opened an editor, exported a file or posted anything. Do not claim any design has been tested with viewers. You are preparing instructions for a person to execute.

WORKED MINI EXAMPLE (fictional, for shape only)
Input: Topic: a beginner guide to making cold-brew coffee at home. Title: Cold Brew, No Fuss. Platform: 16:9 video site.
Illustrative output shape: Direction 1, "Object Hero," centred glass jug on a plain surface, title as two short lines bottom-left inside the safe area, clean and calm. Direction 2, "Split Frame," left half showing the brewing jar, right half a flat colour block holding the full title, bolder and more direct. Direction 3, "Before and After," dry grounds on one side and finished drink on the other, title across the lower third with the two key words emphasised by size only, wording unchanged.
Pass and fail checks for this example: Pass if all three keep "Cold Brew, No Fuss" exactly and place it inside the safe area, and if the three differ in composition. Fail if a direction invents a coffee brand, a health claim, or a number of minutes not supplied, or if the title wording is changed.

Start by restating the topic and title you received, then list missing inputs, then give the three layouts and the comparison line.

# 面向设计师的视频缩略图布局简报提示词

一套可复用的提示词，把视频主题与标题转化为三份不同的缩略图布局简报，并给出文字区域与安全区规则。

## 开始使用

把你的视频主题（一到两句话）和准确的候选标题粘贴进一个接受文本的普通 AI 对话中。把你已有的可选项也一起加上：受众、平台、画幅比例、禁止元素、品牌颜色，或对缩略图可能使用的照片或人物的简单描述。

然后粘贴下方附带的完整提示词。模型应先复述你给出的主题和标题，再列出缺失的输入，然后给出三个布局方案和一句对比说明。如果缺少主题或标题，它应当停下来向你索取。

检查输出时确认以下几点：

- 每个布局中的每个标题词都与你的用词一致、顺序一致，没有增加或删减。
- 三个方向在构图和视觉焦点上不同，而不只是颜色不同。
- 每个文字块都位于所述的安全区内。
- 没有出现你未提供的统计数字、颜色、数量或品牌，除非它被明确标注为假设。

## 这套提示词做什么

它产出的是文字版创意简报，而不是图片。三个布局方案各自给出方向名称、画布与安全区、带大致网格位置的焦点元素、背景层次、准确的文字摆放、一句层级说明，以及两个风险及快速修正方案。最后一句对比说明会指出哪个布局适合哪种氛围或平台。

输出形态的虚构示例（并非真实测试）：对于主题「在家制作冷萃咖啡的入门指南」和标题「Cold Brew, No Fuss」，一个方向可能是居中放一只玻璃壶，标题以小字两行放在左下角；另一个方向则把画面一分为二，一侧是照片，另一侧是承载完整标题的纯色块。

## 输入与权限

你必须提供的内容：

| 输入 | 是否必需 |
| --- | --- |
| 视频主题 | 必需 |
| 准确标题文字 | 必需 |
| 受众、平台、画幅比例 | 可选 |
| 禁止元素、品牌颜色 | 可选 |
| 照片或人物的描述 | 可选 |

如果没有给出平台或画幅比例，提示词应提供两个常见选项，并标注哪个布局适合哪一个，而不是默认其中一种。该提示词是供人执行的纯文字指令；它不应声称已创建图片、打开编辑器、导出文件或发布任何内容，也不应声称某个设计已在观众中测试过。

## 隐私与限制

你粘贴的任何内容都会发送到你使用的那个对话服务，因此请避免粘贴保密品牌素材、未发布的产品细节或你不愿在那里分享的个人数据。输出是给人类设计师的起步简报，不是成品缩略图，它也无法验证实际的可读性。

本指南描述的是该提示词的文档化设置方法。已审阅来源；未做运行时测试。

## 常见问题

**我需要任何软件或账号设置吗？**
不需要。把提示词粘贴进接受文本的普通 AI 对话即可，不涉及终端或 API 设置。

**如果我只有一个大致的标题怎么办？**
提示词只会保留你提供的准确文字，不会改写，所以请先确定最终措辞。如果提示词把长标题分成多行，它必须按顺序保留每一个词。

## 来源与致谢

TokRepo 原创提示词，采用 CC BY 4.0 许可。外部参考：[ChatGPT 版本说明](<https://help.openai.com/en/articles/6825453-chatgpt-release-notes>)——仅为背景信息；本模板并不依赖某个特定已发布功能。

## 完整可复制提示词

你正在帮我为视频缩略图向平面设计师做简报。我会给你一个主题和一个候选标题。只根据我提供的内容工作。不要编造我没有说明的产品名称、标识、统计数据、人脸、品牌颜色或声明。

我将提供的输入
- 视频主题：一到两句话描述视频涵盖的内容。
- 候选标题：准确的标题文字，或必须出现在图片中的词语。
- 可选：受众、平台、画幅比例、禁止元素、品牌颜色。
- 可选：对缩略图可能使用的任何照片或人物的简单描述。

你的任务
为同一个主题和标题产出三份明显不同的缩略图布局简报，以便设计师选择方向。变化构图、视觉焦点和文字摆放方式，而不只是颜色氛围。每份简报都必须是设计师在没有看过视频的情况下也能遵循的完整指令。

输出格式
对三个布局中的每一个，使用以下结构：
1. 方向名称和一句意图说明。
2. 画布与安全区：说明你收到的画幅比例，或向我索取；描述裁切安全区位于哪里，并让所有文字都保持在它内部。
3. 焦点元素：眼睛首先落在什么上，用文字描述（主体、物体、场景），并用简单的网格或分数给出其大致位置。
4. 背景与景深：从后到前描述各个层次。在我已说明没有照片后，不要编造照片。
5. 文字摆放：准确的标题文字、它们占据的文字块、对齐方式，以及标题是主要元素还是次要元素。如果标题很长，说明如何跨行拆分，并保持措辞不变。
6. 层级说明：用一句话说明观看者首先、其次、第三读到什么。
7. 两个风险：该方向的一个可读性风险和一个可信度风险，各配一个快速修正方案。
然后加一句简短的对比说明，指出哪个布局适合哪种氛围或平台，仅基于你写出的方向。

规则
- 不要改写、缩短或美化我的标题。保持准确用词。
- 除非我提供了数字、奖项、价格或对比，否则不要添加。
- 不要提及任何软件、模板包或平台功能。
- 如果我没有给出平台或画幅比例，提供两个常见选项，并标注哪个布局适合哪一个，而不是默认其中一个。
- 如果我的标题超过六个词，提出你会使用的换行方式，并保留每一个词。
- 保持整个回答可读，不要注水。

不确定性与缺失输入
在三个布局之前，列出任何会改变你的摆放或层级安排的缺失输入。如果缺少主题或标题，停下来向我索取这两者，而不是猜测。如果你不确定某个描述的元素是否适合受众，请将其标记为假设。

完成前的检查
- 每个布局中的每个标题词都与我给出的用词一致、顺序一致。
- 三个方向至少要在构图和视觉焦点上不同。
- 每个文字块都位于所述的安全区内。
- 没有出现我未提供、或你未明确标注为假设的元素、统计数字或颜色。

边界
这仅是文字版创意简报。不要声称你创建了图片、打开了编辑器、导出文件或发布任何内容。不要声称任何设计已在观众中测试过。你是在为一个人准备可执行的指令。

迷你示例（虚构，仅示意形态）
输入：主题：在家制作冷萃咖啡的入门指南。标题：Cold Brew, No Fuss。平台：16:9 视频网站。
示意性输出形态：方向 1「物体主角」，居中放一只玻璃壶于素净表面，标题以小字两行放在安全区内的左下角，干净而平静。方向 2「分屏」，左半展示冲泡罐，右半是承载完整标题的纯色块，更大胆直接。方向 3「前后对比」，一侧是干燥咖啡粉，另一侧是成品饮品，标题横跨下三分之一，用大小仅强调两个关键词，措辞不变。
该示例的通过和失败检查：如果三个方向都准确保留「Cold Brew, No Fuss」并将其放在安全区内，且三者构图上不同，则通过。如果某个方向编造了咖啡品牌、健康声明或我未提供的分钟数，或标题措辞被更改，则失败。

先复述你收到的主题和标题，再列出缺失的输入，然后给出三个布局方案和对比说明。
