无损 H.264 MOV 无法使用 Quicktime 打开

无损 H.264 MOV 无法使用 Quicktime 打开

我认为这个问题不同于由图像创建的无损 H.264 MP4 文件无法在 QuickTime 中播放因为这个问题及其答案涉及转换一系列 PNG 图像。接受的答案对我的情况不起作用。它还建议为 crf 选择一个非零值,而我想要一个 0 值。

我需要将一堆 MOV 文件转换为 mp4,以便将它们导入 Apple Photos。我希望转换过程无损。

我尝试使用以下命令来转换单个文件,其中 crf = 0,以使其无损:

ffmpeg -i in.mov -c:v libx264 -crf 0 -c:a aac -map_metadata 0 out.mp4

(in.mov 为 400Mb,out.mp4 约为 600 Mb)

ffmpeg 顺利完成,但 Quicktime 无法打开该文件(该文件与 Quicktime Player 不兼容),并且 Photos 无法导入它。VLC 可以打开它并播放,没有问题。

将 crf 设置为 > 1 的值将导致 quicktime 可以打开文件。

有任何想法吗?
