Best way to replace an Audio Track on x264 Video Movies...

[erosoft]

Hi All,

I'm trying to figure it out from long time and i still haven't found an easy and suitable solution to manage the Audio Track from a Video file.

Just to be clear, i would like to remove the English Audio track and paste and Sync another language Audio.

I have an English Source (audio/video) from a BluRay Disc (ripped in x264) and i would like to sync an Italian audio Source, taken from a DVD.
There is a Software or a couple of Software to perform this job ?

I should manage the footage too, because the x264 is 24fps and the DVD is PAL at 25fps.
In this case i will convert the Video footage from 24 to 25fps and then paste the Italian Audio.

I'm sorry for my bad english, tell me if you need more infromation about it.

Thanks in advance to any answer to this Post.

Have a good Day.

I wouldn't convert the video to 25fps. I would instead change the speed in the 25fps audio to 24 fps(0.04%faster audio), try use belight,eac3to,daudiok(I guess they have some settings to change the speed) . Then mux back the audio to the video using tsmuxer. If you are lucky the video and the audio will match directly or you just have to edit the start to match the new video source. Cut or add silence to ac3 using delaycut.

But the blu-ray disc may be edited in another way then your dvd...then I would give up...too much work....
