class=\"payload-richtext\">\u003Cp>广告封面优化（thumbnail optimization for ads）指的是为视频广告选定并排好播放前展示的那一张静帧：按版位选对尺寸、把主体放在平台安全区内、让首帧一眼就讲出钩子，并用可重复的测试按单次成果成本比较封面，而不是凭好看与否。\u003C/p>\u003Ch2>为什么封面决定一条视频广告有没有人看\u003C/h2>\u003Cp>在大多数版位上，封面在那零点几秒里就是广告本身。Meta 信息流里视频会自动播放，但文件加载时渲染的是首帧，关闭自动播放或网络慢的人看到的也是首帧。YouTube 信息流视频广告和 Facebook 视频信息流里，封面是一张需要主动点击的静态卡片。TikTok 上，封面帧出现在个人主页网格和部分搜索、发现页面里。\u003C/p>\u003Cp>这些场景里封面干的活和视频前三秒一样：让人停下来。如果封面帧是一张运动中的糊片或者从黑场淡入，你为开头写的钩子根本没有出场机会。\u003Ca href=\"https://deepclick.com/resources/blog/ad-hook-first-3-seconds/\">广告前 3 秒钩子\u003C/a> 里的原则同样适用于静帧：封面要在一眼之内呈现主体、场景，最好还有钩子里的张力。\u003C/p>\u003Ch2>各平台视频广告封面尺寸\u003C/h2>\u003Cp>平台规格会变，导出前一定在广告管理工具的预览里再确认一次。下面是目前各平台文档给出的推荐值，作为起点足够。\u003C/p>\u003Cp>Meta（Facebook 与 Instagram） 按 Meta 的广告规格，信息流视频至少 1080 × 1080 像素，移动端信息流推荐 4:5，1:1 也接受。Reels 和 Stories 使用 9:16、1080 × 1920 像素。可以在 Ads Manager 里为视频上传自定义封面，封面比例要和视频一致，否则会出现黑边。Meta 以前限制图片文字不超过 20% 的规则已经取消，但文字过多的封面在移动端仍然普遍表现不佳，因为在信息流尺寸下根本看不清。\u003C/p>\u003Cp>TikTok 按 TikTok 的广告规格，信息流视频为 9:16、1080 × 1920 像素，1:1 和 16:9 也接受。封面可以从视频里选一帧，也可以上传图片。由于 TikTok 界面会在画面上叠加说明文字、账号名、音乐条和右侧操作按钮，画面里有相当大一部分区域不适合放关键元素。\u003C/p>\u003Cp>YouTube 按 YouTube 帮助中心的说明，自定义封面推荐 1280 × 720 像素、16:9，最小宽度 640 像素，JPG、GIF 或 PNG 格式，小于 2 MB。这对信息流视频广告和 Shorts 卡片很重要；可跳过的插播广告会立即播放，封面在那里没那么关键。\u003C/p>\u003Cp>一张母版可以服务三个平台：按 1080 × 1920 构图，主体居中，再裁出 4:5、1:1 和 16:9 版本。先为最高的竖版构图，可以避免一个常见错误：16:9 的画面裁成竖版后主体被切掉。\u003C/p>\u003Ch2>安全区：封面元素在哪里不会被遮住\u003C/h2>\u003Cp>安全区是平台自身界面不会覆盖的那块画面。放在安全区外的东西都可能被说明文字、按钮、账号名或进度条挡住。\u003C/p>\u003Cp>Meta Reels 与 Stories Meta 的 Reels 指引建议把关键文字和 logo 避开 9:16 画面大约顶部 14% 和底部 35% 的区域，那里是页头、说明文字、行动号召和互动栏的位置。实际操作上：把主体和文字放在画面垂直居中的位置，然后在真机上看预览。\u003C/p>\u003Cp>TikTok TikTok 的创意指引把画面底部（说明文字和音乐信息所在）和右侧边缘（点赞、评论、分享按钮堆叠处）标为需要避开的区域。TikTok Ads Manager 里自带的安全区预览会显示当前界面的精确遮挡范围，以它为准，不要用博客里的固定数字，因为这层遮挡已经改过不止一次。\u003Ca href=\"https://deepclick.com/resources/blog/tiktok-ads-creative-best-practices/\">TikTok 广告素材最佳实践\u003C/a> 这篇有完整的安全区示例。\u003C/p>\u003Cp>YouTube 封面右下角会被时长标签覆盖，已看过的视频底边还会叠加进度条。文字避开右下，主体居中。\u003C/p>\u003Cp>一个跨平台通用的习惯：把封面设计在一个居中的矩形里，矩形大约占画面高度的 60%、宽度的 80%，其余部分用背景填充。矩形内的内容在所有界面里都能存活。\u003C/p>\u003Ch2>怎么选视频广告的首帧\u003C/h2>\u003Cp>首帧既是自动播放的开场，也是没设自定义封面时的默认封面。把它当成一个刻意的创意决定，而不是剪辑软件随手导出的那一帧。\u003C/p>\u003Col class=\"list-number\">\u003Cli\n
