Join Maxim Jago for an in-depth discussion in this video An overview of motion effects, part of Media Composer 8.7 Essential Training: 110.
- [Instructor] I have to thank EditStock for giving us this fantastic media, which is so perfect for demonstrating motion effects. We've got these great shots of guys running around, jumping across stuff, and it just helps us to look at speed changes really clearly, broadly speaking, if you exclude things like over-cranking and changing the interpreted frame rate of media, there are three ways you're going to change the motion or play back speed of clips in Media Composer. One option is, you're going to make a freeze frame. So here I can right click in the player monitor, and I can chose freeze frame, and I can specify a duration.
I can tell Media Composer what to do with the fields, and the result is a still image that has no motion, and I can incorporate into my project. Just in this window now, I'm going to press my keyboard shortcut for match frame, which I set up previously as y, but there's a button down here at the bottom of the window, and this will take us back to the source clip with our in and out marks in place. And with the source window active, I can go to our fast menu, I'll our pop our tool palette and click on motion effect editor.
This actually brings up the motion effect that I can use to specify a new playback speed for a new clip that I'm going to generate. Put in the speed, set whether I want strobe motion or not. If I want to just have still images playing instead of Media Composer interpolating the frames. Specify how I want Media Composer to deal with the fields in the media. And then either create without rendering, or create and render, in which I case I need a target where I have a place to store all the new media. The result of this kind of motion effect is something like this.
This is a double speed playback. The original media was very slow, it was one quarter speed. So actually we're still getting this at 50% slower than reality. But again, what you get is a clip that has media associated with it. In this case it's a real-time effect applied to the original media that's linked in the project, and it has a flat speed. The third way to change the playback speed of clips is this one. I've got a clip on the timeline, and I've added to the clip, a time warp effect.
Here it is up in my project window. The time warp effect gives you a different use of this motion effect editor button. So with the record or program monitor active, or the timeline active, when you click this button, in this case, the motion effect editor is giving me the controls to change the passage of time over time. I can key frame to specify different speeds at different stages in the clip. In the next lesson, we're going to look at how to set up one of these effects.
But just for now, I wanted to highlight the difference between this use of motion effects, and the use of motion effects in the source. This is really a special kind of effect editor. And up at the top left I can specify which graphs I'm going to show, and I've got some standard effect controls, Again, I can specify whether I'm going to interpret field-based media in one way or another, and we also have this advanced fluid motion option, which takes longer to render, but can produce really exceptional results for slower frame rates.
Again, we'll come back to these controls in a moment. Notice that with the current settings, I'll just zoom out a little here, this effect has a green dot. And so Media Composer anticipates that it will play in real time. Which it will. So that's three ways for you to modify playback speed for your clips as an effect. But the only way you're going to be able to change the playback speed over time, to ramp the slow motion, is by applying the effect actually to a clip in a sequence.
