I have been asked to create a video of a web application I have developed to demonstrate it's capabilities.
This is something new to me, I have never used any of the video editing capabilities of CS4 Master Colection. I created the video using ZD Soft Screen Recorder.
The problem I have is that this video will be shown to competitive industries so I need to blur out the clients names. I have been using After Effects to try and achieve this (see attached jpg file). This is what I have done so far.
I have imported the video file as a layer and then copied the layer again. I used a Gaussian Blur to blur out the lower layer and then applied a rectangular mask (Subtract) over each field I wanted to blur on the top layer. The effect is just what I'm looking for. The problem I have is that when the screen changes in the video the masks stay where I placed them throughout the entire video. How do I stop the masks after a certain number of frames?
Looking at the way the masks are applied to the whole layer, I can't see any other way of doing this other than cutting the video up into lots of chunks. Is there a better way? If not how do I cut the video up into chunks.
As you can probably tell, I don't know a lot about using After Effects.
iFirth: There are really many ways to do this. For example, each mask has a "Mask Opacity" property (twirl open the mask in the timeline to reveal its' properties). You can animate this property with two keyframes, so the Mask Opacity value goes from 100 to 0 when you want it disappear.
Thanks, I'll give that a try, seems logical and it would mean I wouldn't have to cut the video up.
