I got two complete series of Conan: http://www.imdb.com/...ref_=fn_al_tt_1
One has very good audio in portuguese but bad video and the other one has good image but audio in japanese.
Since i haven't found any good portuguese subs to match the japanese version i tried to mix the two versions.
I googled a bit and after a while i found the mkvmerge program and with that i chose the serie with better video and added the portuguese audio.
In most episodes the sound match the image but specially in the last 7 (and they are 26) it doesn't.
So i tried to strech and delay the sound in order for it to match the video and i started from the end.
In episode 26 i got it. It is more or less ok.
But both in episodes 24 and 25 the sound and video match in the begining of each episode and match in the end. The problem is that they don't match in the middle! (there is a 1 or 2 secs difference)
I'm sure i can't make it right with only these two tools (delay and stretch) so what must i do?
Is it the video i must edit?
Why is this happening?
