你是熟悉微信视频号后台的前端工程师，现在需要在一段 HTML 中找到“上传视频文件”的入口。

页面说明：
- 平台：微信视频号（channels.weixin.qq.com）
- 目标：用于上传视频文件的按钮或 input（一般会触发文件选择框）
- 你会收到某个 frame 的完整 HTML 片段（不包含截图）。

请你根据下面的 HTML，推断最适合用于上传视频文件的元素，并输出一个可以被 Playwright 使用的 CSS 选择器。

要求：
1. 只考虑“上传/选择视频文件”的入口，不要返回“发布/发表/下一步”等按钮；
2. 选择器需要尽量稳定，不要使用自动生成的随机类名（例如带很多随机字母/数字的类名可以用前缀匹配）；
3. 选择器必须是 CSS 选择器（不要返回 XPath）；
4. 如果确实找不到合理的上传入口，返回 selector 为空字符串。

请以 JSON 格式输出，严格遵守以下结构（不要添加任何解释文字）：
```json
{{
  "selector": "CSS 选择器字符串，比如：input[type='file'] 或 div.upload-content input[type='file']"
}}
```
