视频编辑器时间轴界面

生成一张 4:5 竖版 1024x1280 的中文社区缩略图，展示「示例应用」视频编辑器的专业深色模式界面。顶部应用名为「示例应用 视频编辑」。上半部分左侧是媒体素材面板，缩略图网格显示中文素材名，如「开场镜头」「采访片段」「产品演示」「字幕素材」。上半部分右侧是大型预览监视器，显示暂停帧、播放控制条和中文时间码标签。下半部分是多轨时间轴，包含「视频一」「视频二」「音频一」「音频二」「特效」五条轨道；视频片段为彩色矩形，音频片段带绿色波形，琥珀色播放头竖线贯穿所有轨道。界面按钮使用「播放」「暂停」「导出」「剪切」「字幕」。不要出现真实软件商标、英文菜单、水印或乱码。

A realistic desktop screenshot mockup of a professional video editing application at 1920×1080, dark-mode. Layout divided into three zones: top-left is a media bin panel showing thumbnail strips of video clips labeled "Clip_001" through "Clip_007" in a grid; top-right is a large preview monitor showing a paused frame (a blurred abstract gradient placeholder) with playback controls beneath it — rewind, play/pause, forward, timecode display reading "00:02:34:12". The bottom third is the timeline: five horizontal tracks labeled "V1", "V2", "A1", "A2", "FX". Video clips on V1 appear as color-coded rectangles with waveform thumbnails inside; audio tracks show green waveform graphs. A vertical red playhead line crosses all tracks at the current position. A zoom control slider sits below the timeline. Color palette: #111318 background, #1D2130 panel backgrounds, amber #F5A623 playhead and selected-clip highlight, muted clip colors. Monospaced timecode font.
