Trouble with keyframing videofx

OK you guys,..I'm a newbie. Please go easy!! what in the Sam Hill am I doing wrong!!??

I have a video on the timeline. I drag a video FX to that clip.

The video FX covers the "entire clip" and I ONLY WANT to have the fx on a small section of the clip.

I open the Video Event FX editor and then:

I double click midway in the video clip (mini timeline at the bottom of the editor box) which adds a keyframe. I move down a bit more on the clip and double click again to add another keyframe (the point where I want the effect to conclude).

I play back the video in preview and the FX still continues through the entire clip!!! UGHHH! I must be stupid!!

I tried to just select the "first" keframe icon to mark exactly where in the video I wanted the effect to begin, (but all it did was move the timeline to the very beginning) and then the "last" keyframe icon where I wanted it to end,...but all that does is force the mini timeline to the end.

I'm missing something here!!! It can't be this difficult!

Key frames aren't "immediate jumps." They aren't On/OFF switches, but reference points.

Time Line:
Y________________________R___R___________________________Y

Let's say you have a yellow background that you want to be red for a certain point in the middle. If you set up your keyframes like they are above -- with yellow at each end and red keyframes in the middle -- you will have your "red" where you want it...but everything in between will be varying shades of ORANGE.

If you want the yellow to stay yellow, then jump to red for a spot, then go back to yellow, you have to do this:

Y________________________YR_____RY_____________________________Y

The middle "YR" and "RY" would be adjacent frames. This will give you the "ON?OFF" you want.

I put together a demo:

You need to breakup the timeline into "events" then drop the filter within the event boundries. Then only the event is effected. To make an event, place the curson on the timeline where you want to break, click, then Edit/Split to set a break point on the timeline. You now have two "events" on the timeline which can be acted on independently.

KH,
That is singlehandedly the BEST description I have ever read!!! You made it so much clearer for a thick headed guy like myself. Thanks soooo much!!! I printed it off!!! The clouds have lifted.

Jes - still it's better to learn your way first to get a grasp of how keyframes work. the keyframe properties like 'hold' are for lesson 2. nice description!
