The VideoLAN Forums

I have a .mkv video and trying to convert it to a MP4.
The conversion is working, however, I'm unable to add somes subs to it.
I do include the subs file in "Use a subtitles file" then I also tick Subtitles and Overlay subtitles on the video and I choose DVB subtitle for it.
Am I doing something wrong?

VLC is not the best too for this. Use Avidemux or virtualbox or handbrake.

But can we still do it anyways?

Or how do I do it with VirtualBox? The newest Avidemux doesnt support adding subtitles and handbrake adds too much noise

MP4Box can convert some subtitles to the TTXT format and add them to an MP4 container.
