Hi,
i'm editing a dcoumentary of about 40 min. I made a color correction on single clips but now i'm thinking about find another way to do that. Is that possible (with a simple click :) ) to delete all the media fx i've applied instead of open media fx event on clips and delete one by one the effects?
And is that possible to apply effects on entire clips instead of segment on timeline?

Yes it is. A script can easily remove all effects from one or more clips. Excalibur (http://www.jetdv.com/excalibur) and Ultimate S (http://www.vasst.com) can both easily do this.

Here's a free script (http://www.jetdv.com/vegas/forum/viewtopic.php?t=2962) that will also delete effects from selected video events. If the effects were added in the project media, this script would need to be modified to work there.

Thank you very much!
