I am using a mask and the blur effect for only a couple of seconds. I understand I have to use keyframes to indicate when to start and stop this effect in the video, so that the same area is not burred for the entire video.
The problem is, I cannot find help in properly setting keyframes. When I open the keyframes menu under the effects, it looks like I have to set it for both the mask took, and the blur effect. Which I did...to start and stop at specific times, but the effect remains throughout the video, so obviously I am missing something in using the keyframes. The manual for creating effects is not helpful. I need help with keyframes as what I am doing clearly is not working. Help!
Thanks Richard, I think that worked! Thanks for the help.
