Ffmpeg avs到avi无损转换

时间:2016-02-20 10:39:41

标签: ffmpeg avi avisynth

如何在没有质量损失的情况下将avs(Avisynth文件)转换为avi?

首先,我将avs改为264:

ffmpeg -i" Source.avs" -c:v libx264 -preset veryslow -crf 24" Output.264"

其次,我试图将264转换为avi:

ffmpeg -i" input.264" " output.avi"

最终avi应该有近200MB,但只有2MB。 264文件有近150MB,所以应该是好的。我认为我应该在第二个命令中使用一些编解码器,但我不知道哪个。我试图改变这几天,但没有效果。

或者也许有一种方法可以在没有264的情况下进行无损转换,只有avs到avi?

感谢您的帮助。

谢谢你的回答。不幸的是,两种方法都失败了。 首先给我一个视频,这是模糊的,我无法看到任何内容。

答案 0 :(得分:4)

您的Avisynth输入是未压缩的,因此您可以将其包装在AVI中,如下所示:

ffmpeg -i source.avs -c:v rawvideo -pix_fmt bgra source.avi

不需要通过H.264进行中介。在任何情况下,您的命令都不会产生无损H.264。为此,你需要

ffmpeg -i "Source.avs" -c:v libx264rgb -crf 0 "Output.avi"

(如果源包含alpha通道,这将是不可接受的,因为H.264不支持alpha)
