You haven't given many details but if you're after what i suspect you are then rest assured. It's easy enough. i suspect you got no answer because the same question has been asked a handfull of times in the last couple of weeks.

Anyway, to apply the same effect to a whole groups of clips at the same time do the following.

Add the set of clips to a sequence and edit them as required.

Create a new sequence.

Drop a copy of the first sequence intot he timeline of the second, new sequence.

That set of clips nwo appears as a single clip in the second sequence and can be editted as such. Just drop an effect on it and it will effectively apply the same effect tothe entire set of clips.

Hope that helps.
