Audio question: how to change audio language to a divx file

[superfresko]

Hello everybody!

I'm Italian and here in Italy everything is dubbed, including TV Series.

Since in the Internet high-quality captures of TV Series can be easily found, what I wanted to do is capture the italian audio and then "put" it on the engligh-spoken high-quality captures.

Thus, I have to sync the italian audio on the english-spoken video and audio (editing out the italian commercials).

What software could I use to do this? (Both freeware and not freeware.)

Any suggestion?

Thanks.

Bye bye,
Massi.

Hello !

First, you should extract the English audio to HD, using the VirtualDub Mod for avi files and TMPGEnc for mpeg files , so that you can load that in an editor and have time references .

Then you capture your Italian audio . I don't know what you want to use, but TotalRecorder is quite good, and the program I use for audio editing generally, and which is probably one of the best, namely CoolEdit, can also capture audio .

Start the cpture a minute before the start and also end it a minute later .

Now have a look, opening both the old audio and the new Italian one with CoolEdit, if the part of the Italian audio that corresponds to the English audio has the same length . I do not know if the English audio may be sampled in 48 Khz, and if you can capture that way, and also, capture may always have a little desynch or stretching .

If it has the same length (very exactly ; you can still 'see' a desynch down to 1-2 tenths of a second), then you need to cut that part out of your capture carefully . You may have to, as you said in your post, have to cut out the commercials before hand , and count the time after that .

If it does not have the same length, you need to cut out the part of the audio that you need carefully, and then perform stretching operations on it, hopefully preserving pitch . A 48 Khz --> 44,1 Khz or the other way round conversion may also help .

When you are done, save the stuff as wav, and use the VDub Mod or TMPGEnc again to multiplex your old video with the new audio again (and encode it to mp3 or mp-audio on the way) .

Hope this helps .
