Page9：视频转换与压缩Page 9: Convert and compress video

1. 悬浮球：五个工具的入口1. The floating ball: where the five tools live

主界面右边缘有一颗蓝色悬浮球，位置可以拖动。鼠标移上去它会展开，从下往上是 Video Convert、Compress Video、Extract Audio、To GIF，以及 RipDVD。

A blue floating ball sits on the right edge of the main window and can be dragged anywhere. Hover it and it expands upward into Video Convert, Compress Video, Extract Audio, To GIF and RipDVD.

这些工具全部属于 MC DVD Premium：免费版点开先看到购买窗；已解锁则直接进入工具窗口。工具窗口是独立窗口，关掉就回到主界面。

All of them belong to MC DVD Premium: in the free version a purchase window appears first; once unlocked the tool opens straight away. Each tool is its own window — close it to return to the main app.

3. 压缩视频（Compress Video）3. Compress Video

压缩和转换是同一个窗口，只是进来时已经切到压缩模式：目标格式固定保持原样，重点是把体积降下来。适合「片子太大，微信 / 网盘传不动」的场景。

Compression uses the same window, opened in compress mode: the container stays as it is and the point is a smaller file — for when a clip is too big to send or upload.

1. 悬浮球里点 Compress Video；
2. Add Files 加入要压的视频；
3. 确认 Output Path；
4. 点 Start Compress，等完成提示。

1. Press Compress Video in the floating ball.
2. Add Files to add the clips.
3. Check the Output Path.
4. Press Start Compress and wait for the completion prompt.
