如何减少视频文件大小,同时保持质量

为邮件、网页和存储等应用,学习压缩视频文件的实用技巧。包括在浏览器中运行的工具,无需上传即可工作。

视频文件较大时,1080p 视频的100-200MB 可能取决于编码和比特率。通过电子邮件、消息应用程序或网页上传这些文件通常需要大量的压缩。

视频压缩的最佳方法是找到质量和文件大小之间的平衡。H.264 (AVC) 仍然是最兼容的编码,而 H.265 (HEVC) 提供了 30-50% 的压缩率,在相同质量下。

分辨率是文件大小最大的因素。从 4K 到 1080p 下缩通常会减少文件大小 75%。从 1080p 到 720p 节省 50%。对于电子邮件和消息,720p 通常已经足够。

帧率也很重要:60fps 视频的数据量是 30fps 的两倍。除非你分享体育或游戏视频,那么 30fps 更为流畅且更紧凑。

ConvertCraft 的视频压缩器,全部可以在浏览器中处理。选择你的目标分辨率和质量预设,工具将生成一个优化过的 MP4 文件,使用 FFmpeg WebAssembly — 无需上传到任何服务器。
