I'm trying to add a delay relative to video of -7ms but for some reason mkvtoolnix won't do that...
Avidemux can but it doesn't keep the soft subtitles...
The reason I want to do this is because the source file has a delay. After re-encoding the source with handbrake the delay is kept but when adding attachments to the mkv container with mkvtoolnix the delay is lost... I want to add the attachments without losing the delay.
Watch the video below it'll explain things better.

It works from the GUI. From the command line it's "--sync 1:-7", assuming track 1 is the audio.
mediainfo it indeed shows there's a -7ms delay relative to the video I still get silence at the beginning of the video.
The silence can be fixed with avidemux by toggling the shift box and adding -7ms but you lose the attachments and subtitles that were added with mkvtoolnix.
The source file has no silence.
Here you can find a video where I recorded what I was doing and showing the problem.

Add the 7ms delay to the videostream.
