Here are some tips for getting the most of Optical Flow Time Interpolation in Premiere Pro.
So I'd like to show you this clip that I have of this hoverboarder doing this really interesting move over the sea here, and I'd like to slow that down and make it even more interesting.
So I can use clip Speed/Duration and set it to 50%, and it does slow it down. But if you look closely, you'll see that it's just duplicating every other frame. I'd like to go back to the Speed/Duration dialog and set it to Optical Flow. I need to render it, and what this does is it actually interpolates new frames in between so that I get a much smoother motion effect.
Do you see here as I scrub through it I'm actually stepping frame to frame here, and you can see that there's no repeated frames because where there weren't real frames, we've interpolated new frames for you and gives you a really nice motion effect.
But I think I can make this even more interesting using our Time Remapping effect. This effect is not new to Premiere Pro 2015, but it works really well with the Optical Flow interpolation which I just showed you, so I'm going to add some key frames here. I'm going to stretch each one out a ways to give it some bézier handles so that I can get a really nice motion in my Time Remapping here.
I'm going to set this down to 10%. And see when I drag that down, I get a ramp down and a ramp back up. So let's play this back and see what we have. And so it comes in; it slows down; it plays through at 10%;and then it speeds back up. Really cool.
But we want to turn on Time Interpolation Optical Flow again so that we're interpolating those new frames. We'll render again and play that back, and you see how nice and smooth the motion is? You can get a really good look at what he's doing. In fact, I like that. That came out so nice.
I'm going to turn this all the way down to—let's go with 3%. And then I'll have to render that again and play that back and now we have some really interesting motion going very slow, but not chunky at all because we've interpolated new frames as we need them to get some really nice slow motion. Let's watch that one more time all the way through. So that's a little taste of what you can do with Optical Flow Time Interpolation in Premiere Pro.
Create better-looking, smoother slow-motion effects by using Optical Flow and Time Remapping effects in Adobe Premiere Pro CC.
- Open the Speed/Duration dialog box, set Speed to 50% and select Time Interpolation > Optical Flow.
- For better results, click Effect Controls > Time Remapping and Add Keyframes (optional to reduce and then increase speed within the same clip).
- Set speed for your slow motion.
- Once you’re happy with the speed, click on Time Interpolation > Optical Flow for smooth slow motion.
