Video with Music problems

[( . )( . )]

I have a video and a corrensponding music, I got both into the background and they're playing together, when they don't get disturbed that is.

They're working perfectly together, because they're both the same length.
When I do something else, the music gets disjointed from the video; how do I make the music dependent on the video and not independent like it would do with random sound effects?

use MKVToolNix GUI to mix both together
unless you are doing some playback scripting on video texture, there should not be any problem

Can you elaborate on this?
I understood nothing.

What Luke means is that this is possible by making the audio part of the video file, but only for basic "video" type wallpapers. Judging from your other threads, you are making a "scene" wallpaper, is this still the case?

If you are making a video wallpaper, then you should make the audio part of the video. Video wallpapers are just like normal video players, the audio and video is played by the same system and will be synchronized. So this would work as you would expect in any other video player.

If you are making a scene wallpaper, then this is using a "video texture" and it is not a plain video player anymore. Synchronizing an audio file with a video texture in this case is unfortunately not possible and not something we can currently add. We are legally limited to using certain video systems and they don't allow us to synchronize multiple videos or audio files that are played with a completely different system. In general, this kind of behavior is more in line with a video editor, which does not work in "real time" but it "prerenders" everything into a video. Scene wallpapers are completely real time and not prerendered, so they are the opposite of that.

This is the third wallpaper I am making.
The other 2 wallpapers benefit from the first post, but only the second benefits from the second post.
Yes, it is a scene wallpaper, I believe.

I'd like to know of a video editing software that gives me the option to cut/edit video and audio layers without adding a watermark?

I saw the animation thing somewhere, would that work with syncronizing audio with a video texture?

"Real Time" and "Prerender" doesn't tell me 100% what kind of loading it is.
"Stream from Disk" and "Stream from Memory" does tell me more.

You can use OpenShot or Avidemux for example. Both are open source and completely watermark free. ^^
