ffmpeg - ffmpeg 导出无颜色丢失

Question

我正在尝试通过 ffmpeg 为视频添加水印，但所有导出都会导致颜色信息丢失。我想保留与原始视频相同的颜色信息，我该怎么做？

目前，我使用以下代码：

./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "

我意识到不丢失颜色信息的唯一方法是将-crf设置为0并将-preset设置为veryslow，但这会导致文件非常大。（原视频大小的2倍，无效）

运行 ffpmeg 时也出现此错误：

[swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly

请参阅此处的图像比较 - 出口上的黑人不像原始人那样“黑色”

ffprobe -show_streams 用于原始文件
