Maybe someone asked this before but I did everything I found and did not work, like update Quicktime and to ffdshow software. None of them fixed my problem. Never used it before for movie clips, just to remix music. Now found out the movie format issue. I have a Canon S5 si, movie format: mov. Audio drags fine but w/o video. Anything new I can still try to make this work? Do I need to upgrade something? Thanks in advance, Rafi
