Transition and Effect Problems

Question

two problems: 1) i cannot add transitions to my movie. it says the clips are too short and must be 3:46:16 each! but the clip preceding are 7 and 10 seconds long! what do i do? 2) when i want to make a clip black and white, i go to the effects section. i apply it to the clip i want B&W. BUT, when i apply it, it sometimes makes the clip black (just a black screen for the clip with the applied effect). what do i do?

Answer 1

. it says the clips are too short and must be 3:46:16 each! but the clip preceding are 7 and 10 seconds long!
3:36:16 reads as 3minutes, 36 seconds, 16 frames..
you can not apply a 3min long transition to a 10sec clip...
make the transition shorter... 00:00:09 ....
for your B/W problem:
if you're using the 'Quarz Composer b/w', use the slider 'sharpness' to set it correctly...
