Part 2: Frame Blending & Motion Blur in Final Cut Pro 5: Free Tutorial

Video Transcript

This is C.J. South representing expertvillage.com. In this clip, I am going to finish up talking about frame blending and motion blur. You see motion blur; it's by default it's unchecked because motion blur takes a hell of a long time to render. So they don't normally put it to things so just go ahead and click that. Now you see what happened to that. It's kind of gotten faded and it has almost like I duplicated the box 6 times behind it. Now if you look you have different percentages. You've got this blur percent and you have samples. The more you raise the sample watch what happens. It's going to be more boxes that appear behind the canvas. So now you've got a ton of different samples and they just kind of blended together. So now at 32, that looks like a pretty nice motion blur effect and to change the blur percentage, you can move that down to less blur which blurs the picture less or move it up for even more blur which just makes it look like lines. That will give you an effect of hey, this is moving because when you move your hand in front of your face, you see this blur. You don't actually see the hand in its entirety. You kind of see a blur going so this makes it look more natural. Now going back to changing the time, hit apple or command J to bring the speed back up. You got something called frame blending in here. Now what is frame blending? Well frame blending adds blurred frames to your clip and that also makes it appear that it is running smoother. So when frame blending is off it doesn't really matter I guess if its a 100 percent but when you move it down or move it lower, frame blending is pretty important to keep on until you get to a certain point, then you need to have it off because it just looks weird. What it will do is it will take because remember when you are storing down footage, you are adding extra frames to it so you are adding duplicate frames to this to make it appear like it is slower because it's not true slow motion; it's digital slow motion. So what that will do is it will take two frames that have added an extra frame of the same frame it duplicated it. It will take those two and will add another frame in between it, that's a blurred version of those two frames together; two half's of that frame. So it will blur it to look more natural. So if you add motion blur and frame blending, chances are you are going to have a really nice motion to it. It is going to look pretty good.
