Upload Video Compressor
Shrink videos so they actually upload, send, and publish cleanly.
Problem it solves
Teams often lose time because a video is simply too large for the next step: upload limit, slow transfer, rejected platform, bloated review file, or awkward handoff. This skill focuses on compressing for practical upload readiness, not generic technical tinkering.
Use when
- - A video is too large for social, ads, storefronts, or internal handoff
- A creator needs a lighter export fast
- The goal is upload readiness, not archive mastering
- A team wants a clearer size/quality tradeoff decision
Do not use when
- - The video is already over-compressed and degraded
- The task is cinematic mastering
- The user needs restoration or quality enhancement, not compression
Inputs
- - Source video file
- Target platform or use case
- File size limit if known
- Preferred tradeoff: smallest possible, best possible, or balanced
- Optional resolution and audio constraints
Workflow
- 1. Identify the real upload or handoff constraint.
- Choose an upload-safe compression profile.
- Reduce size while protecting practical watchability.
- Preserve clarity in faces, products, demos, and text where possible.
- Return the best upload-ready version and explain tradeoffs.
Output
Return:
- 1. Compression approach
- Upload-ready output profile
- Estimated reduction
- Quality tradeoffs
- If needed, the next compression step
Quality bar
- - Optimize for upload success and practical clarity
- Avoid crushing the file into unusable quality
- Make size/quality tradeoffs explicit
- Keep output compatible with common publishing workflows

上传视频压缩器
压缩视频,使其能够顺利上传、发送和发布。
解决的问题
团队常常因视频文件过大而浪费时间,无法进入下一步:上传限制、传输缓慢、平台拒绝、审核文件臃肿或交接不畅。本技能专注于为实际上传需求进行压缩,而非泛泛的技术调试。
适用场景
- - 视频过大,无法用于社交媒体、广告、店铺页面或内部交接
- 创作者需要快速导出更轻量的文件
- 目标是为上传做准备,而非存档级母版制作
- 团队希望在文件大小与画质之间做出更清晰的权衡决策
不适用场景
- - 视频已被过度压缩,画质严重受损
- 任务涉及电影级母版制作
- 用户需要画质修复或增强,而非压缩
输入
- - 源视频文件
- 目标平台或使用场景
- 已知的文件大小限制
- 首选权衡方案:尽可能小、尽可能好,或平衡方案
- 可选的分辨率和音频限制
工作流程
- 1. 识别实际的上传或交接限制条件。
- 选择适合上传的压缩配置文件。
- 在保证实际可观看性的前提下减小文件体积。
- 尽可能保留人脸、产品、演示和文字内容的清晰度。
- 返回最佳的上传就绪版本,并说明权衡取舍。
输出
返回:
- 1. 压缩方案
- 上传就绪的输出配置文件
- 预估压缩比例
- 画质权衡说明
- 如有需要,下一步压缩建议
质量标准
- - 以上传成功和实际清晰度为优化目标
- 避免将文件压缩至不可用的画质
- 明确说明文件大小与画质的权衡关系
- 确保输出兼容常见的发布工作流程
