Hi
VP 8.67
There does seem to be a bug with the stand alone Shake effect. Using two clips on the timeline and applying the effect to the second clip using the default values (10,10,0,10), it seems to work OK. Replaying from the previous clip and it still works OK.
If, however you think the default values are too vigorous and decide to change the 10 to say, a 5 the effect is lost and Shake does not play any longer. The effect does not appear to play even if the parameters are altered before the clips are played.
My conclusion at the moment is that the effect will not work except for the default settings. Even if you alter the values back to 10,10,0,10 the effect is still lost.
As you seem to have it working check out if it STILL works if the parameters are altered slightly.
