I made a video and put it on youtube. months later i wanted to change the music... so i downloaded it back off youtube and went back on the magix movie edit pro 14. i want to know how can i cut off the music and just use the video. i tried to lower then dm of the sound and when i add the new music even with adding that db higher it is not good enough to cover up the old music. thanks. Also I noticed when Im editing my video in the top left video box where i can watch what i got so far it shows this red clock counting the video sequence how to i turn that off it is annoying.
