I am trying to get my blur area to be selected using the Ellipse tool (the round thing you can expand). This is for a blur . But when I use it, doesn't seem to do anything? I apply the blur effect and the whole video gets blurred, not just my target area! The method I'm using comes from a Youtube tutorial-- I track motion, there's a Null layer, then I use an Adjustment Layer, parent that and tried to use the Ellipse to blur the tracked area. But it's obviously not working.
I thought I was doing that before but it worked today by doing the same steps. Maybe I wasn't parenting properly or ... maybe I didn't select the Adjustment layer after all. Now I got the right area selected for blur but it appears the blur is not marked by key frames or key markings, the Beginning and End of the Tracking Motion? It appears to just continue blurring throughout the entire clip! What did I do wrong?
It's not clear what you are doing, however you should be able to keyframe the amount of blur to 0 when it isn't needed. Depending on which type of blur you are using it can be called things like Blurriness or Blur Radius or Amount etc..

Hi! It seems you're at a weird place in your knowledge of the program - doing motion tracking etc but fundamentals may be lacking. It may be good to go brush up on fundamentals of the program before really getting into more advanced projects. Here are a few tutorials that may help you out: Setting, selecting, and deleting keyframes in After Effects
I'm adding the key frames in the right positions but am not seeing a response by the program. This means the blur effects works wonderfully where it's applied but it keeps going after and before my key frames.
Have you got two keyframes close to each other at each time the blur changes (so you have keyframe 0% blur then keyframe 100%, then at the next change keyframe 100% then keyframe 0%, then next change keyframe 0% and then keyframe 100% etc.)
Things like knowing how keyframes work are baby basics which you need to learn and understand or you will drive yourself crazy. I recommend that you look at some basics tutorials such as these extremely good ones:
This discussion would be far more productive if you post a screen grab of your timeline with all pertinent keyframes visible. Select relevant layers and press UU to display all changed properties and keyframes of selected layers.
