Hope there's an easy answer to this . Usually I use handbrake for my encodes, but Handbrake doesn't do video passthrough. I'm therefore hoping that someone here might know the answer. I use MakeMKV to rip my blu-ray films. What I was wondering is how I can convert blu-ray movies to a quicktime compatible mp4 file without compressing the video. In ohter words passthrough. What I was thinking was this: 1) Rip the movie using MakeMKV 2) Demux the mkv. 3) Convert the audio file to a compatible format (for example AAC) 4) Use a program to mux the audio back with the untouched video file into an mp4 container. The problem I'm currently having is figuring out what program to use for remuxing the video and audio file into an mp4 container. Any ideas?
