How-to limit effects to apply only to part of a timeline???
Start with a video which includes a brief pan that includes a troublesome, overly bright or oddly colored elements within, say, a wall window showing the outside scene.
OK. Use the qualifier to select that window with respect to HSL. OK. Use color wheels to make desired changes to the HSL selected bits. This also may unavoidably capture other elements in the frame.
OK. Use a mask to restrict the qualifier to a limited spatial area.
OK. The troublesome window now looks acceptable and the color changes are contained with that window.
So far so good.
But later in the timeline, these window, qualifier and color wheel adjustments show unintended side effects.
OK. Just limit the temporal scope of these effects–the qualifier, the power window/mask and the color adjustments–to that short bit of the timeline.
BUT HOW??? (Gotta happen every day for a professional and there probably is a keyword or name for this.)
Razor-blade that short bit in the edit timeline??? Surely there is a smarter way.
I have tried static keyframes as begin and end markers: then turn off the mask within that keyframe.
OK. That may limit some but not all of the effects, such as color wheel adjustment.
Any thoughts???
Thanks,

In Resolve you can apply color correction & FX to the whole track or clip by clip.
In your case it sounds like you want to keep your adjustment to a clip basis. If you want to apply the same correction to the following clip, it is easy enough to copy your nodes and paste them to the new selected clip.HTH,

Actually the goal is to apply effects only to portions of a clip.
Sorry, I was not clear.
For example, if a pan within a clip captures an offending wall window with its overly bright light levels and prominent but uncomplimentary color elements, one can use a qualifier to manage that color and a mask to isolate the effect to that spatial area.
But that effect remains throughout the clip.
True, one can use keyframes to enter and end this mask effect within those keyframes. That is, turn off the mask. But the color effect does not turn off and it remains throughout the clip.
The goal, then, is to play the clip to the point needing an effect, create and apply that effect only for the duration needed, and thereafter continue to the end of clip without that effect.
Thanks,

can’t you just keyframe part of the FX you want to change overtime? I am not sure what you mean by “color effect” but you can certainly keyframe any of your color adjustment, independently of your power window.

does the window not remain for the entire clip? How long is this clip?
Go to your keyframe area and select auto keyframe for that node.
Go to your key page and adjust the gain of the matte to be either on or off during the shot.Glenn
