I'm working on a short clip where I have text fading in at the beginning and out at the end. Then I've added a blur effect to the entire clip, and used keyframes to have the picture start out blurred, then come into focus as the text fades in, and blur out of focus as the text fades out.
My keyframes are set like this: 0 seconds into the clip, blur is at 100%. At the peak of text fade-in, the blur is set to 0%. I have another keyframe set to 0% at the frame before the text starts to fade out, this way there is zero blur for the middle portion of the clip. At the end of the clip, where the text is fully faded out, I have a keyframe at 100%.
This is working OK -- the blur fades in and out along with the text -- but at the exact frame where it goes from about .01% to 0% blur, the text jumps from looking blurry, to being perfectly sharp. As in, it looks really sudden, rather than a smooth transition.
I've tried adding additional keyframes so that the blur fades away in the smallest possible increments right before going to 0%, and it's still really sudden and jumpy looking. I've even removed the blur effect all together, and then re-added it in a separate effect track just to see if that would make a difference. My project is at 24FPS, if that matters.
Any ideas?
