yesterday i had the chance to be integrated in the video-cut of my title „perspective“, we recorded last summer. alex, the mastermind of cutting, introduced me in his work. we had a good workflow and did the second part of the song. but finally  a problem occured: alex used a mp3 file in the audiotracks. as we removed the file into a real wav-audiofile, the synchronisation failed in some parts. so never use a mp3 file in a professional work!!!!
