ProRes 为什么是「干活」的格式,家族怎么排?

概念说明CONCEPTS

Apple 的制作/中间格式,帧内压缩——每一帧独立压缩,不依赖前后帧;所以剪辑随便跳、随便切,画面经得起调色。

原理:每一帧独立完整

什么时候用:剪辑与调色的工作格式、交付母版、要交给后期的大文件。

操作步骤STEPS

  1. 剪辑与调色的工作格式选 ProRes(起步 422)
  2. 需要 alpha 通道选 4444
  3. Windows 先装解码器
  4. 发平台前仍要转 H.264/H.265

练习PRACTICE

动手任务

把同一段素材各导一条 ProRes 422 与 H.264,对比文件大小,再各拉一条曲线看表现。

自检清单

做完任务后逐条自查,全部能打勾才算过。 做完任务后逐条自查,全部能打勾才算过。

常见问题FAQ

422 / 4444 怎么选?

家族递增 422 → 422 HQ → 4444 → 4444 XQ;4444 带 alpha。够用就 422。

Windows 能用 ProRes 吗?

能,但要先装解码器;发平台前仍要转 H.264/H.265。

Learning Objectives学习目标

Why is ProRes the "working" format, and how is its family ordered?

Concepts概念说明

Apple's production / intermediate format with intra-frame compression — every frame compresses on its own, no dependence on neighbours; so you can scrub and cut anywhere, and the picture survives grading.

Each frame stands alone

When to use it: the working format for editing and grading, delivery masters, the big files you hand to post.

Steps操作步骤

  1. Pick ProRes as the editing/grading working format (start at 422)
  2. Choose 4444 when you need alpha
  3. Install the decoder on Windows
  4. Convert to H.264/H.265 before publishing to platforms

Practice练习

Hands-on task

Export the same clip as ProRes 422 and as H.264; compare file size, then pull a curve on each.

Self-check

Work through the task, then tick every line; all checked means you own this card. Work through the task, then tick every line; all checked means you own this card.

FAQ常见问题

422 or 4444?

The family rises 422 → 422 HQ → 4444 → 4444 XQ; 4444 carries alpha. 422 when it's enough.

Can Windows use ProRes?

Yes, after installing the decoder; platforms still get H.264/H.265.
