Join Nick Harauz for an in-depth discussion in this video Introduction to time-based effects, part of Sapphire for Video Editors.
- [Instructor] This movie has everything to do with time. It's not a pun. I know that we're dealing with video editing, but it does have everything to do with Sapphire's time, and the effects you have to work with time from Sapphire. I'm here in my Chapter 6_5 sequence which you can find in your Chapter 6 bin under the exercise bin. One thing that we need to know is that Sapphire is used for many platforms, so some of the effects aren't something that you would use as a Premiere Pro editor 'cause they are built into Premiere Pro, such as wonderful effects to slow down and speed up and reverse your footage by using the retime editor or pressing control R.
However, one other interesting thing about time is that it often goes overlooked in the Sapphire effects. And that is, if I go to the video effects category, all Sapphire time effects, in particular, every one minus one of them, Flicker, doesn't show up in terms of being able to preview that effect, whether it be in Builder, whether it be in your library of presets if you use S effect. I don't want you to overlook these 'cause some of these are extremely powerful. The first example that I'm going to give you is called TimeWarpRGB.
S_TimeWarpRGB. I'm going to apply it to this first clip here in my timeline. Now, with this clip selected and that effect now on it, I will shift 5 to go to effect controls. You might notice that there's a very small split in the red, green, and blue channels of this clip. What this RGB time warp does, is it shifts the red channel, the green channel, and the blue channel by as many frames as you want to create almost like a time parallax. To really highlight this point, I'm going to shift my red channel by negative 50.
I'm going to shift my green channel in the positive direction by 10. And finally the blue channel by, probably about 60 frames. So this is just an idea to start with, and I'm going to go to the beginning of the clip. Time effects are rather intensive, so something to keep in mind. I'm going to actually just bring down my resolution to hopefully get a slightly better playback. If you can see here, on this slowed down clip, what's happened of how this has been warped, in terms of RGB, you can get some pretty cool type looking effects here by playing around with the shifting of frames.
And you're not limited to just one of those. You can, of course, increase that amount if your clip is a lot longer to create even cooler effects. And here, with that separation, you can sort of see these different startings for each of my red, green, and blue channels based on the amount that I've shifted them in terms of their frames. Play with that a bit more and check it out. I'm going to get rid of the time warp effect on this clip. I'm going to go over here to the second clip here in my timeline. What I'm going to is just throw on S_Trails and show you that this just kind of produces a really realistic type of trail effect.
By playing around with the brightness of the previous frame and the hue shift, some of the controls and effect controls, you can get some pretty cool results, so something to definitely check out. Now last but not least on our time journey in this particular movie, I wanted to show you what's called Time Displace. What I have is actually just a really simple gradient on top. You can see it moves here, it's linear, from the bottom left-hand corner. It's white, all the way to black, and there's sort of a hard change. Now we can use these values, this gradient's values, to basically represent which part of the frame plays a little bit earlier and later.
And there's just nothing like this in Premiere Pro. So if I go to the S_TimeDisplace and throw it on the track on V1. What we're going to do is have it reference the matte on V2, which is our gradient. And the V2's black and white values, we can shift time by a series of frames based on the current frame that we're on. In fact, I'm going to shift the black value by negative 26 and the white value in the opposite direction. I just want you to look again at where white and black is, and see how that kind of distorts your clips based on that line there in the gradient.
You can kind of see how it looks. So, a very interesting effect. You can think about other ways of using this with raindrops or basically with things potentially falling in the sky, and displace time with a linear gradient from top to bottom. So, definitely have some fun fooling around with these time-based effects to expand your possibilities with time in Premiere Pro.
