Free video downloader
Download public videos from YouTube, TikTok, or Instagram. Videos must be no longer than 10 minutes and no larger than 100 MB, at up to 720p. No account required.
当您有公开视频链接时使用此功能
The video downloader accepts YouTube, TikTok, and Instagram links. It is useful for quick offline review, reference files, research notes, and videos you own or have permission to save.
If your link is from YouTube, TikTok, or Instagram Reels, the dedicated tool usually gives clearer instructions and better intent matching.
Start with the most specific downloader
Use this page for any of the three supported platforms, or pick a dedicated downloader for platform-specific instructions.
如何下载在线视频
- 复制公开视频网址。 打开源页面并复制分享链接或地址栏网址。
- 粘贴到 Sceneform。 将链接添加到表单并选择您想要的分辨率。
- 开始下载。 Sceneform 会检查公开链接并准备可用文件。
- 保存视频。 将结果下载到您的设备，并在允许的离线工作流程中使用。
下载器最适合公开可访问的视频页面。它无法解锁私密账户、付费资源库、已删除视频或需要登录会话的页面。
影响下载质量的因素
Video quality is controlled by the source file and the variants the source platform makes available. Choosing 720p in a downloader cannot create real 720p detail from a low-resolution upload.
- Source resolution: the original upload sets the upper limit.
- Platform variants: some sites offer multiple video qualities; others expose only one.
- Restrictions: private, age-gated, region-blocked, or removed videos may fail.
- File type: the result is intended as a playable video file for normal devices and editors.
保存公开视频的理由
当文件支持具体工作流程时，下载才有意义。保存公开片段用于离线查看、学习、产品研究、创意参考或您自己的已发布媒体存档。
- 在旅行或没有稳定网络时查看教程。
- 保留创作者参考以了解节奏、构图和结构。
- 保存公开演讲、演示或讲解视频供团队研究。
- 在编辑或重新利用之前备份您拥有的视频。
仅以您被允许的方式使用下载的文件。如需转发或商业使用，请获得创作者的许可。
免费、无需账户、临时文件
The video downloader is free to use and does not require a Sceneform account. Downloads are limited to 100 MB, 10 minutes, and 720p.
Processed files expire after one day. The page is built for quick public-link downloads, not permanent hosting or a saved download library.
