If you want to replace the audio after you export the music video… Video software (using the Premire) to re-export troublesome, I finally found to examine the ffmpeg!

The video is copied and the audio is AAC encoded, and the processing ends soon!

I was allowed to reference

Supplement

Until we reach the top way…

Separate and join

Extract only the video from the original video and then combine another voice… .

It takes time that the video is encoded by this method of joining.
I tried to find a way to combine it with copy, so I got an error.

Error 1

-Vcodec copy-acodec copy 

Error

Error 2

Another way of examining

A little different error
