saturate degree of effects between 2 points

remember there used to be a "point a" & "point b" type of enable button up in the right hand corner of every video effect to allow you to have the degree of effect change over the course of an event between 2 points? (like the begin & end points when pan/ cropping). i noticed it was gone a while ago but i really need that ability now. how are we doing that nowadays (and what was wrong with the old way?) using VMS plat 8.

thanks!

I have never used version 8 of VMS Platinum, but in version 9 you use keyframes to control the degree of effect change between two points in time during part or all of an event. Every effect has a keyframe editor at the bottom of the effect control window. What's good about the keyframe method is that it gives a lot of control over how effects are performed over time. Explaining how to use the keyframe editor is a bit involved because there's quite a bit to it. I suggest experimenting with it, and checking out the help file to get you going on it. As Martha Stewart would say, the keyframe editor is a good thing.

Now instead of having just a beginning value and an ending value, you can have a near-infinite number of "keyframes" where you specify new values for an effect's control settings.

Each effect has a mini-timeline at the bottom, and you can position the cursor at any point on that timeline, add a new keyframe there, and specify the settings you want at that point in time.

This is much, much more flexible than the old "start value / end value" method. For example, you might want apply the "black and white" effect to a photo that is on the screen for 10 seconds, and have it start out fully b&w and gradually change to fully color during the first 2 seconds. Apply the b&w effect to the event, set a keyframe at the beginning that makes it fully b&w, then at a point on the mini-timeline 2 seconds from the beginning add another keyframe and set the values there to disable the b&w effect.

Look up info about "keyframes".
