Ffmpeg-将MOV文件转换为MP4 [英] ffmpeg - Converting MOV files to MP4

问题描述

我刚刚安装了ffmpeg，我正在尝试将我上传的所有视频编码为.mp4文件。目前大多数用户上传.mov，我希望将每个视频都转换为.mp4。

我按如下方式运行该命令：

ffmpeg -i movie.mov -vcodec copy -acodec cop out.mp4

但我得到的只是以下错误

推荐答案

只将其流传输到Adobe Premiere Pro等一些应用程序所需的新容器(Mp4)而不进行编码(快速)的命令是：

ffmpeg -i input.mov -qscale 0 output.mp4

备选如评论中所述，以最佳质量重新编码(-qscale 0)：

ffmpeg -i input.mov -q:v 0 output.mp4
