what video format can i export into Magix Music Maker 12 deluxe? non of my videos wants to import!!! no matter what i try it doesnt accept my video files.
what format can u use coz most video files is AVI MP4 WMA
First if you are trying to "export" a file, into Music Maker, you are asking the impossible. You cannot export any file into any application. You need to import the file, or open the file in an application. Of the three file types you listed, AVI and MP4 are container formats that include video and audio among other things. The only audio file format that you mention is WMA, and if you want to open a WMA file, just find the file and drag it to the time line.
WMA, MP3, and WAV files are all audio files and work just fine in MM but you don't export or import them you just drag and drop them.
Adding to George's detailed reply, Music Maker is a basic audio composing and editing program; I don't think it can import video at all. For this function you would need either Magix's Pro grade 'Samplitude' (at a pro price!) if your main interest is music production, or choose a program like Movie Edit Pro. MEP is designed as a video editor but does offer some audio editing as well.
As you already have MM I'd suggest going for MEP to use in parallel -- create your music in MM and then import it into MEP as the soundtrack for whatever video you want. The latest version is MEP 2013. Older versions would no doubt be adequate if you are doing less adjustment to your videos and are often available (new or used) from sites like e-bay. I still have MEP 14 installed on an older computer that gets occasional use.
Why not download a free trial version and check it out? http://www.magix.com/gb/free-download/ (The UK site seems to offer more choices!) If you think you might expand your video editing I'd recomend you go for at least the 'Plus' version.
