Black White Text Opener

黑底白字片头

Role

角色

Create a short, reusable opening animation: black background, large white text that appears one character at a time, synchronized typing click SFX, optional word replacement, and a clean transition into the main video.

This skill is generative. Do not copy source frames or promise pixel-level alignment with a reference. If the user asks to exactly match an existing video, route to

rn-replica-qc

first.

创建一个简短、可复用的开场动画：黑色背景，大号白字逐字出现，并同步加入打字点击 SFX，支持可选的词语替换，最后干净地转入主视频。

此 skill 用于生成式创作。不要复制源视频帧，也不要承诺与参考视频达到逐像素对齐。如果用户要求精确匹配现有视频，应先转至

rn-replica-qc

。

Defaults

默认设置

Duration:
```
standard
```
4.8-5.8s.
Background: pure or near black, no busy decorative background.
Text: large white sans-serif, centered or slightly above center.
Motion: black hold -> white text types in character by character -> phrase holds -> replacement text types in -> final typed phrase holds -> transition out.
Audio: quiet typing clicks aligned to visible character appearances. Do not add clicks during black hold, final hold, or transition-only frames.
Build tool: HyperFrames for polished video projects; Remotion when the project already uses Remotion; ffmpeg only for simple utility openers.

时长：
```
standard
```
，4.8-5.8s。
背景：纯黑或近黑，不使用繁杂的装饰性背景。
文本：大号白色无衬线字体，居中或略高于中心位置。
动效：黑色停留 → 白字逐字输入 → 短语停留 → 替换文字逐字输入 → 最终短语停留 → 转场退出。
音频：安静的打字点击声，与文字出现同步。黑色停留、最终停留或仅包含转场的帧中不要添加点击声。
构建工具：高质量视频项目使用 HyperFrames；项目已经使用 Remotion 时使用 Remotion；仅用于简单实用的片头时可使用 ffmpeg。

Workflow

工作流

1. Create The Timing Plan

1. 创建时间规划

Use the bundled script to generate a deterministic plan:

bash

python3 scripts/create_opener_plan.py \
  --title "AI workflow engine" \
  --replace "from idea" "to shipped video" \
  --final "Build in minutes" \
  --preset standard \
  --typing-cps 14 \
  --out opener-plan.json

Use the plan as the source of truth for scene timing and copy. Do not improvise new copy during rendering unless the user asks.

使用内置脚本生成确定性规划：

bash

python3 scripts/create_opener_plan.py \
  --title "AI workflow engine" \
  --replace "from idea" "to shipped video" \
  --final "Build in minutes" \
  --preset standard \
  --typing-cps 14 \
  --out opener-plan.json

将该规划作为场景时序和文案的唯一依据。除非用户另有要求，否则渲染期间不要临时发挥新文案。

2. Build The Animation

2. 构建动画

Follow the motion contract:

hold black before text appears
reveal each text state one character at a time
align typing click SFX to the same character timestamps
keep the first readable phrase large
use only 1-3 replacement states
hold the final phrase long enough to read
transition out cleanly into the next scene

For dark SaaS/product videos, this opener can precede

rn-dark-saas-video

; keep the opener simpler than the main product scene.

遵循 motion contract：

文字出现前保持黑屏
每个文字状态逐字显现
打字点击 SFX 与对应的字符时间戳对齐
保持第一个可读短语足够醒目
仅使用 1-3 个替换状态
为最终短语留出足够的阅读时间
干净地转场至下一场景

对于深色 SaaS/产品视频，此片头可以放在

rn-dark-saas-video

之前；片头应比主产品场景更简洁。

3. QC

Before handoff, verify:

first frames are black or near black
characters appear sequentially rather than all at once
typing clicks line up with the character reveal and stop during holds
white text is readable at mobile size
no text clips outside frame
no accidental colored flash
no persistent neon-line background
transition lands before the next scene starts
media specs match the target project

If this opener is inserted into a longer video, export both the standalone opener and the full composition when practical.

交付前，请验证：

前几帧为黑色或近黑色
字符按顺序出现，而不是一次性全部显示
打字点击声与字符显现对齐，并在停留期间停止
白色文字在移动端尺寸下仍清晰可读
文字没有超出画幅
没有意外的颜色闪烁
没有持续存在的霓虹线条背景
转场在下一场景开始前完成
媒体规格符合目标项目要求

如果此片头被插入到更长的视频中，请在可行的情况下同时导出独立片头和完整 composition。
