Export and Projects

Export and Projects / 导出与项目

Editable projects / 可编辑项目

Save the editable .timeline project when you need to continue later or share the complete edit. The project is the source of truth for clips, timing, captions, transforms, effects, and audio relationships.

需要继续编辑或分享完整工程时，请保存 .timeline 项目。它是片段、时间、字幕、变换、效果和音频关联的可编辑来源。

Project files may reference or contain media depending on the workflow. Keep original media until you have reopened and verified the saved project.

根据工作流不同，项目文件可能引用或包含媒体。重新打开并验证保存结果之前，请保留原始素材。

Video export / 视频导出

Timeline Studio separates real-time preview from deterministic offline export:

• Preview uses native media playback for responsive editing.
• The primary export path resolves exact timeline timestamps, renders the shared composition, mixes audio offline, and encodes MP4/WebM with WebCodecs.
• MediaRecorder is a compatibility fallback when the primary path is unavailable.

Timeline Studio 将实时预览与确定性离线导出分开：

• 预览使用原生媒体播放，保证编辑响应。
• 主导出路径按精确时间戳解析画面，使用共享合成逻辑渲染，并离线混音后通过 WebCodecs 编码 MP4/WebM。
• 主路径不可用时，MediaRecorder 作为兼容回退。

Export checklist / 导出检查

1. Preview the complete timeline once.

2. Confirm captions, overlays, masks, filters, animations, and audio visibility/mute states.

3. Keep the tab active during heavy export stages.

4. After saving, verify dimensions, duration, visible overlays/captions, and audible audio.

5. 完整预览一次时间线。

6. 确认字幕、画中画、遮罩、滤镜、动画以及音频可见/静音状态。

7. 大型导出阶段保持页面处于活动状态。

8. 保存后检查尺寸、时长、画面叠加、字幕和实际音频。
