Customize: X account intro motion short

Create a [15–30] second account introduction motion graphic video for my social media account, so that people who see me for the first time will know who I am, what I post, and why I am worthy of following. The rhythm is tight and the animation details are many. I want to pay attention after watching it. Please feel free to be creative.

Real information about the account (only use this, do not make up any data, names, experiences or works):
- Name: [nickname], account @[account], platform: [X / Xiaohongshu / Station B / Douyin...]
- Positioning in one sentence: [Who am I and what do I do]
- Content direction: [keywords within 3]
- Masterpieces or achievements: [real works, data, experiences, if not, delete this line]
- Fans [Number of fans], [Number of works] posted, [Number of likes] received (Delete this line if you don’t want to reveal the data)
- Original text of introduction: [Paste introduction]
- Avatar: assets/avatar.jpg (can be used; if you have screenshots of your work, put them in assets/ and explain what each picture is)

Delivery requirements (technical constraints):
- Use code to generate the screen in the current directory. The technology stack can be selected by yourself. You can use the local node/ffmpeg or npm package in this directory.
- Put the finished film into out/intro.mp4: [1920×1080 horizontal screen / 1080×1920 vertical screen], 30fps, H.264; with soundtrack or sound effects, aligned with the rhythm of the picture, with moderate loudness (about -14 LUFS).
- The visual style grows out of the headshot and content direction, instead of using a general technology style template.
- The text on the screen should be mainly [Chinese], the tone should be sincere and memorable, and no empty AI-accented slogans should be used; the last screen should have a name, account number and one-sentence positioning.
- Export another out/cover.jpg as the video cover. The size should be the same as the final video, and the best frame should be taken.
- After rendering, use ffprobe core specifications to check blank frames, text overflow, and misalignment frame by frame. If there are any problems, fix them yourself.
- Write out/description.md after completion: creative ideas, storyboard timeline, and known deficiencies.
- Don't git commit/push, don't publish anything online.

For best results, run it with Claude Fable 5.2.
