如何使用「视频转 GIF 动图」？How do I use the Video to GIF Converter tool?
在「视频转 GIF 动图」中，按需设置「开始（秒）」、「时长（秒，≤30，留空为 5）」、「宽度」、「帧率」、「速度」等选项，然后点击「用当前位置」、「生成 GIF」按钮即可。支持拖放文件。In the Video to GIF Converter: Set "Start (s)", "Length (s, ≤30; blank = 5)", "Width", "Frame rate", "Speed", then click "Use current position", "Create GIF". Drag-and-drop files is supported.
GIF 文件为什么这么大？Why is the GIF so large?
GIF 是很老的格式，每帧最多 256 色且压缩效率低，同样内容通常比 MP4 大 5–20 倍。想让文件变小：降低宽度（如 320 px）、帧率（8–10 fps）或缩短片段；画面变化少的录屏比实拍视频小得多。GIF is an old format — at most 256 colors per frame and weak compression — so it's usually 5–20× larger than MP4 for the same content. To shrink it, reduce width (e.g. 320 px), frame rate (8–10 fps) or length; screen recordings with little motion are far smaller than camera footage.
全局调色板和每帧调色板有什么区别？Global vs per-frame palette?
全局调色板从整段视频中挑选 256 种颜色，所有帧共用，画面不会闪烁、文件更小，适合大多数情况；每帧调色板为每一帧单独挑色，颜色变化很大的片段（如场景切换）色彩更准确，但可能出现轻微闪烁。A global palette picks 256 colors from the whole clip and shares them across frames — no flicker and smaller files, best for most clips. A per-frame palette chooses colors for each frame, which is more accurate when colors change a lot (e.g. scene cuts) but can flicker slightly.
支持哪些视频格式？Which video formats work?
浏览器能播放的格式都可以：MP4（H.264）、WebM、MOV（H.264）等；HEVC/H.265 视频只有部分浏览器和系统能解码。帧是按时间逐帧精确截取的，不受电脑速度影响；片段最长 30 秒、最多 450 帧。Anything your browser can play: MP4 (H.264), WebM, MOV (H.264) and so on; HEVC/H.265 decodes only in some browsers and systems. Frames are captured precisely by timestamp, independent of your computer's speed; clips can be up to 30 seconds / 450 frames.
视频会上传到服务器吗？Is my video uploaded?
不会。所有处理都在你的浏览器里完成，文件不会离开你的设备，所以也不受上传大小和网速限制（但受电脑内存和性能限制）。No. Everything runs in your browser and the file never leaves your device, so there are no upload limits or waits — only your computer's memory and speed.
