Sorry for a basic question, but I'm not a seasoned user !
Well, untill now, when importing video, the associated audio used to be automatically grouped with video, allowing to move each event (sound + pictures) as a whole.
I must have done something without realizing it, because now, whenever I import some video from the media pool, and move an event, audio and video are no longer linked (audio event stays while video moves)!
Any idea about where I messed ?
Thanks !
