先学：Prerequisites: 节点编辑器

学习目标LEARNING OBJECTIVES

学完你能说清 MediaOut 节点的作用，把节点树正确接入输出，并排查"回编辑页面没画面"的问题。

概念说明CONCEPTS

MediaOut 节点是节点树的终点——连进它的画面就是合成的最终结果，会被送回编辑页面和调色页面的时间线。

  • 每个合成自带：新建合成时 MediaOut1 已等在节点编辑器里，它是整条管道的出水口。
  • 连什么输出什么：只有接入 MediaOut 的分支才会渲染回时间线；没连上的部分再漂亮也只是草稿。
  • 永远收尾：MediaOut 是节点树的最后一环——不能删，也不该绕过。

操作步骤STEPS

  1. 把节点树末端节点的输出方块，拖到 MediaOut1 左侧的橙色三角输入上把节点树末端连进 MediaOut1
  2. 选中 MediaOut1 按 2，在右查看器确认这就是最终输出画面
  3. 按 Shift-4 回到编辑页面播放，确认时间线上能看到合成结果回到编辑页面确认时间线画面
  4. 画面不对就跳回 Fusion，从 MediaOut1 沿管道往前逐节点按 1 / 2 排查

练习PRACTICE

  1. 把任意效果链连进 MediaOut1，回编辑页面确认可见；再断开它看时间线变黑（最后记得连回来）。
  2. 用 1 / 2 键沿节点树逐环检查，找出画面从哪一环开始不对。

常见问题FAQ

编辑页面看不到合成结果怎么办？

先查 MediaOut1 的输入有没有连上——只有连进它的画面才会渲染回时间线。

能删掉 MediaOut 节点吗？

不能，也不该。它是合成送往其他页面的唯一出口，永远接在节点树的最后。

节点编辑器里预览正常，时间线却不对？

你预览的很可能是中间节点，而输出走了另一路。选中 MediaOut1 按 2，看到的才是真输出。

Learning Objectives学习目标

After this card you can explain what the MediaOut node does, wire a node tree into the output correctly, and troubleshoot "nothing shows up back on the edit page."

Concepts概念说明

The MediaOut node is the finish line of the node tree — whatever feeds it becomes the composition's final result, sent back to the edit and color page timelines.

  • Every composition has one: MediaOut1 waits in the Node Editor from the start — the drain of the whole pipeline.
  • What you connect is what you get: only branches wired into MediaOut render back to the timeline; anything left unconnected is just a draft, however pretty.
  • Always the last link: MediaOut closes the tree — it can't be deleted and shouldn't be bypassed.

Steps操作步骤

  1. Drag the output square of your last node onto the orange input triangle on the left of MediaOut1Wiring the end of the tree into MediaOut1
  2. Select MediaOut1 and press 2 — confirm the right viewer shows the final output
  3. Press Shift-4 back to the edit page and play — the timeline should show your compositionConfirming the result on the edit page timeline
  4. If the picture is wrong, jump back to Fusion and walk the pipe upstream from MediaOut1, pressing 1 / 2 node by node

Practice练习

  1. Wire any effect chain into MediaOut1 and confirm it on the edit page; then disconnect to watch the timeline go black (wire it back afterwards).
  2. Walk the node tree with 1 / 2 and find the exact stage where the picture goes wrong.

FAQ常见问题

Nothing from my composition shows on the edit page?

Check whether anything is connected to the input of MediaOut1 — only what feeds it renders back to the timeline.

Can I delete the MediaOut node?

No — and you wouldn't want to. It's the composition's only exit to the other pages, always the last link in the tree.

Preview looks right in the Node Editor but the timeline is wrong?

You're probably previewing an intermediate node while the output takes another path. Select MediaOut1 and press 2 — that's the true output.
