I synced the English dub to my 4K video from Deaf Crocodile as well. Nice to see someone else has done it too.
It is obvious that an English version was meant to be released by the original creator. The computer screen video
is in English on this Deaf Crocodile release while on the DVD I have they are in German.
How did you fix the overlapping audio issue? I used AI text to speech to recreate the dialog and then
mixed it in.
I synced the German surround track from the DVD to the 4K as well.
Your English Surround mix using stems sounds like an interesting idea. I am definitely interested
in checking out your work.
