使用ffmpeg将视频从.264转换为.265(HEVC) [英] Convert videos from .264 to .265 (HEVC) with ffmpeg

问题描述

我看到有一些关于此主题的问题，但我仍然收到错误。我所要做的就是将库中的视频转换为HEVC格式，以便它们占用更少的空间。
我试过了：

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

Ffmpeg似乎需要很长时间，输出大小似乎也差不多。视频可以用VLC播放，但图标很奇怪，当我尝试用QuickTime打开它时，我收到错误消息：‘无法打开文档"output.mov。该文件与QuickTime播放器不兼容。’

我不想更改任何花哨的设置。我只希望文件占用的空间更少，质量损失最小或没有损失。

谢谢！

编辑： 记不住我放在视频中的时间戳。
最初我是在终端中使用exifTool。但是，有时这对视频不起作用，所以我会把它们空投到我的iPhone上，用一款名为Metapho的应用程序更改日期，然后再空投回来。ExifTool被创建了，但有时我就是不能工作。它会把日期改到8月2日的1109212左右。怪怪的。底线是，当我进行这些转换时，我真的不想丢失其中的时间戳。

我加盖时间戳的原始文件，格式为.264
