If I have 2 video clips running in one slide, 1 as a BG the other has movement via keyframes, and they both have soundtracks, I know I can mute either of them for the duration of the clips. However, is it possible to mute both or either of them for specific periods via the keyframes. ie: clip 1 used as the BG runs from KF 1 to KF 2 with sound. KF 2 - KF3 no sound allowing clip 2 sound to play, then mute clip 2 and resume clip 1. Is that possibel? Andrew
