Rich: Now that I've adjusted the speed of the clip, I need to tell After Effects how to get there. You see, you have the option to repeat frames, blend frames, or essentially morph between them. Let's take a closer look. I'll zoom in a bit here using the comma or the period keys to control zooming in or out. And I just want to go to an area that I could really see the clouds. Holding down the Spacebar, I can drag and move. As I go through, you'll see that I stretched the clip 300%. So when I go forward one, two, three, frames, you'll see it transitions to the next frame. One, two, three, there's the transition.
One, two, three. Well, that's pretty straight forward and that's no frame blending. Essentially the frames are repeated three times. If we turn on Frame Blending, we can first enable it globally, then in Draft mode for the individual layer. What will now happen is that the first frame will be frame A. The second frame will be 2 3rds frame A with 1 3rd of frame B ghosted together with an opacity adjustment.
Clicking forward, it's now 1 3rd frame A and 2 3rds frame B. Going to the next frame, it's now frame B. And that pattern repeats. Essentially, with frame bending, you get opacity blends between the different frames. And what you're seeing there is a smooth transition. Let's do a RAM preview. Now, we have a little flicker here caused by the light changing and we'll deal with that later.
But look at the clouds moving through with the frame blending. I have one more option though, and that is Advanced Frame Blending. This is significantly more processor intensive. But what happens here, and when I'm at full quality, you'll really see it. Is that it attempts to morph from one frame to the next. Sometimes this works really well. Other times it could be problematic like you see here, the clouds are really shifting around.
Rarely will you use advance frame blending. But instead, go with the draft mode. And that's looking a lot better. Let's watch that back, here's about three seconds blended. And the clouds are moving very smoothly, making a nice liquid type time lapse. Now the flicker we'll deal with in a moment, and that has nothing to do with the camera and everything to do with the fact that the sun was moving.
Before we can start to refine that, let's go ahead and make a few adjustments to this overall clip.
