Hi, i want to start a project but i have no idea where to start. I have a barbie movie collection that has dubs in my native language. I found that someone has remastered these movies in HD and i have already downloaded them. The movies are however in English. I want to rip the audio track from the dvd's but just of the main movie and replace the original audio track from the remastered movies. I've already tried to rip the movie with handbreak but the mp4 file came out choppy in image and in audio. I also don't know how to replace the original audio track once i have successfully ripped the audio from the dvd as well as sync it. I've read about using ffmpeg but i have no experience with it except for yt-dlp. If anyone can provide an incredibly dumbed down explanation, i would really appreciate it.
