i am trying to match portions of a song to different changes in video and images changes. it is easy to do UNTIL the video clips become very short and / or the music beat changes... and then it does not preview correctly. how can i make the video changes match the music exactly and get it to preview correctly? thanks if you can help, i appreciate this forum very much. i hope that i have explained this well enough, i am not sure what what i am trying to do is called... thanks
