Is there any software to combine/split audio, video, and subtitles?

It needs to be free. I've used a program that did this once before, but I can't find it installed on my computer and I don't remember the name of it.

sony vegus is free for 30 day to try and is not thta costly to buy. see if that software will do what your looking for. a lot of the free software has extra garbage in it like malware.

You can use ffmpeg for basic manipulation of video, audio, and subtitle streams.

You can also just use windows movie maker if you want something a bit more user friendly. Not sure if WMM supports subtitle editing though.
