如何使用「视频截图 / 视频抽帧（导出高清图片）」？How do I use the Video Frame Extractor (Video to Images)?
选择或拖入视频，播放或拖动进度条到想要的画面，可以用“上一帧 / 下一帧”精确定位，点“截取当前画面”即可下载。批量抽帧时选择间隔秒数或总张数、起止时间，点“开始抽帧”，最后打包下载或生成预览拼图。Choose or drop a video, play or scrub to the moment you want (use Prev/Next frame for precision) and press Capture. For batches, choose an interval or a count and the time range, press Extract, then download a ZIP or make a contact sheet.
截出来的图片清晰度是多少？What resolution are the stills?
默认按视频的原始分辨率导出，例如 1080P 视频得到 1920×1080 的图片，4K 视频得到 3840×2160。选 PNG 是无损的；JPG 文件更小。也可以在“输出宽度”里缩小。By default the video’s own resolution — 1920×1080 for 1080p, 3840×2160 for 4K. PNG is lossless; JPG is smaller. You can also downscale with Width.
为什么有的视频打不开？Why won’t some videos open?
工具使用浏览器自带的解码器，MP4（H.264）、WebM 基本都支持；部分 MOV（ProRes）、MKV、HEVC/H.265 视频在某些浏览器里不能播放，可以先用视频格式转换工具转成 MP4 再截图。The browser’s own decoder is used: MP4 (H.264) and WebM work almost everywhere, but some MOV (ProRes), MKV or HEVC/H.265 files do not play in every browser — convert them to MP4 first.
最多能抽多少张？How many frames can I extract?
一次最多 1000 张。抽取很多高清 PNG 时会占用较多内存，建议分段抽取，或选 JPG 并降低输出宽度。Up to 1000 per run. Many full-resolution PNGs use a lot of memory, so extract in parts, or use JPG and a smaller width.
