Question video/audio merge

[ultraman36]

Hey I have a question on merging a blu ray video with Dvd audio. Year ago I brought a blu ray video Cold prey. The movie is subtitled. There is a dvd version that has dubbed english. How would I combine the dvd audio with the bluy ray video? (also keeping the audio in sync)

Use MakeMKV to rip DVD and BluRay to mkv. Then use Mkvtoolnix (GUI) to merge the tracks you want to combine. You may or may not have to change audio delay and/or video fps to make them match. If the cuts are different (i.e. like a director's cut vs. cinema cut) it becomes more difficult.

Thanks not sure how to handle it as there is a 4 minute difference between the 2 files.

Could be fps. The playtime is 1:37. The difference between 23.976 (NTSC BluRay) and 25 (PAL Norwegian DVD) is about 4% (about 4 min)

Change with Audascity -> Fillters -> Change speed

Or in mkvtoolnix GUI select the video track and change "fps" to 25.
