Sorry to bother you guys but does anyone know if the quality of a video will decrease if i try to mux in a new audio file with mkvmerge. I basically converted one of my dvds into a mkv with the original japanese language but now i want to add in the english dub version as well but i am concerned if i do this the overall quality of the video will deteriorate. If anyone can shed some light on this, i would be grateful.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Muxing has nothing to do with encoding so no quality is lost on the video,its just combining audio and video.
I think,therefore i am a hamster. -
Basically, the video file is untouched & so is the audio file you use, muxing just brings the 2 of them together to make a single file.

Cool thanks, i was asking because when i did it before i thought i saw the quality was lower but i guess it was all in my head.

But doesn't converting twice degrade the video? I think he converted it once for the Japanese, then wants to convert the Japanese verison to add the English. Won't the two conversions degrade the final product?
There are no problems - only chances to excel.

This is not the case with (re-)encoding with lossy formats such as MPEG-1/2/4, WMV, DivX, Xvid, H.264/x264, etc.I hate VHS. I always did.
