使用ffmpeg

我看到有关此主题的几个问题，但我仍然遇到错误。我要做的就是将库中的视频转换为HEVC，以便占用更少的空间。
我已经尝试过：

ffmpeg -i input.mp4 -c:v libx265 output.mp4

ffmpeg似乎要花费很长时间，并且输出似乎是正确的大小。该视频将在VLC上播放，但该图标很奇怪，当我尝试使用QuickTime打开该视频时，出现错误：“无法打开“ output.mov”文档。该文件与QuickTime Player不兼容。

我不想更改任何高级设置。我只希望文件占用更少的空间，并且质量损失很小或没有。

谢谢！

编辑：无法保留我在视频中添加的时间戳。
最初我在终端中使用exiftool。但是，有时这不适用于视频，因此我会将其空投到iPhone上，使用名为Metapho的应用更改日期，然后将其空投回去。 Exiftool已创建，但有时我无法使用。它将日期更改为类似于8月2日1109212的日期。奇怪的。最重要的是，当我进行这些转换时，我真的不想失去其中的时间戳。

我在.264中加了时间戳的原始文件
