fx effect changing over time

Renton Maclachlan · April 8th, 2008, 05:26 PM

I have a colour correction issue.

I have a clip on the time line to colour correct.

So...the cursor is towards the end of the event...

I press event fx icon, call up the colour corrector, and change the settings to what I want.

If I then click on an earlier part of the event, the CC circles move back towards default positions.

It looks like some sort of automation/keyframe is controling the application of the fx but I want the CC to apply the same across the whole event without change.

Never seen this before. Have I turned something on?

Keyframes allow changing settings over time. You're adding a new keyframe toward the end of your effect. The first keyframe hasn't been changed. Therefore, it's changing from nothing (the first keyframe) to your settings (the last keyframe) over time. I have an article explaining keyframes in one of my newsletters - just look through the archives.

Thanks Edward,

I'm familiar wth keyframes and they way theynchange effects over time, but have never come across them with colour corrector, especially when I can't see the keyframe window showing me what is going on.

I simply do not want keyframes applying in this instance.

Is it automatic that a keyframe is put in even though I don't want keyframes at all?

How do I make the CC apply to the whole event without invoking keyframes?

This is the first time I have been aware of this happening, and wonder now if CC that I thought was ok in the past may not have been, because I was thinking it applied to the whole event but it did not. Is this a trap for young players?

Ok, so I've remembered how to bring up the keyframe window and can see what is happening now.

However, is there anyway for the CC settings you choose, to be applied to the whole event regardless of where the cursor is?

To the left of the keyframe options is an icon containing a lock. ("snap to cursor") Turn that option OFF. Then it will always default to the first keyframe instead of wherever the cursor is located.

Thanks again Edward. That sounds like what I am after.
