I am using Sony vegas Studio Platinum 10. From time to time a music track that I have loaded into the timeline seems to clip the last few seconds. By which I mean the music track is fine when i first put it on the timeline and then at a later stage of editing when I replay the video I find that the last few seconds of that music has no sound....although you can still see the waveform up to the end of the track. Reloading the music from the project media page does not fix the problem. I have to delete that piece of media from the project, re load it into the project media window and then copy onto the timeline. Often I like to have the music track loaded on the timeline whilst I edit the video so that I can synch them so I wonder if something I am doing on the video line is affecting the music line. It does not happen all the time however. Anyone any ideas?
