In Avid Media Composer 5 Essential Training, author Ashley Kennedy demonstrates basic and intermediate editing techniques in Media Composer, one of the most widely used nonlinear, video editing systems. This course covers how to build sequences, mix audio, color correct footage, apply effects, and troubleshoot common post-production issues in Media Composer. Exercise files accompany the course.
Changing the timing of a clip or segment is a very common effect. And Media Composer can do this in a number of ways. If you simply want to speed up or slow down a clip without the need for a clip to change speed within itself, you can use the Motion Effect Editor. And if you'd like to make a freeze frame out of a clip, which means the clip has absolutely no motion and is merely a static image, you can use the Freeze Frame Creation tool. Both of these tools produce new clips with new media. And for this reason they are called source-based adjustments.
Let's take a look at how it works. First of all let's go over the Motion Effect Editor. The Motion Effect Editor can be found in the Command palette. So let's go ahead and grab it from the Tools menu. And Command palette, again Ctrl+3. And it's under the FX tab. And it's right here, the very first one. Hope I'm still on Menu to Button Reassignment. So I'm going to choose Button to Button. And let's go ahead and just drag this under my source monitor. And we'll close out.
What you need for a Motion Effect Editor is an in and out point so that it knows the portion of the clip that you'd like to speed up or slow down and here I have that marked. If I have a clip marked and I click on the Motion Effect Editor, the Motion Effect dialog box comes up. There's a couple of parameters here, Duration and Rate, Frames and Frames per second, that will all change based on what you put in the % Speed box.
By default it goes to 50.00% Speed. And you can speed this way up. You can slow it way down. You can even go in reverse motion. Let's try something at about 50.00% Speed and something at about 250.00% Speed. And then we'll also look at something in reverse motion. So we'll do 50.00% Speed and one thing you always want to change is your Render method. Duplicated is one of the worst render methods you could choose. A very good one for you to choose is Interpolated.
So without going into the specifics on what this means, I'll go ahead and just say choose Interpolated. We want to choose the render drive. Again all of my media is going to the D drive. So I'll choose that. Because this is actually going to render some media. And we're going to Create and Render. It takes just a moment to render out. And when it's done, a new clip is going to appear in the bin. If I expand it, you can see that it has a little bit of a different icon. It matches the Motions Effect Editor icon.
And it shows the frames per second of my clip. Now because my footage is traveling at 24 frames per second and I chose a 50.00% Speed clip, this is a 12 frame per second speed clip. It also automatically loads in the source monitor. So let's take a look at what this looks like. It looks about half-speed, which it is. That's that. I'll go ahead and load the original clip again, again with my in and out points, Motion Effect Editor. This time let's go ahead and choose 250.00% Speed.
And if I wanted to I could actually Strobe. It will update based on the amount of frames that you put in this box. I'm not going to choose that right now. But it is an option. Again we want Interpolated. We wanted to go to the D drive, Create and Render. And this is going to go pretty fast. Let's go ahead and see what this looks like. Fast ballerinas, all dancing around. One more time let's go ahead and put a negative number in here.
Let's do -100.00% Speed with a Strobe updating every 8 frames or so. So this is going to go in reverse motion, real time with the Strobe effect. A lot of different options here. Again it loads -24.00% frames per second with a Strobe every 8. And that's what this looks like. I'm going in reverse with kind of that Strobe like motion.
So the Motion Effect Editor is pretty easy to use. Let's go ahead and load my original clip in again. And let's choose a frame that would be a nice representative frame for say a title. How about right there? That's a nice symmetrical frame and I'd like to use that as a freeze frame. I'm going to park right here. I'm not going to have an in or out point. Just my position indicator. I come up to Clip. I come to Freeze Frame and I simply choose the amount of seconds that I want my Freeze Frame to run.
20 seconds is nice. One thing you do want to do here is change the render method. Again Duplicated is awful. Go to Interpolated. We'll go back and choose my 20 Seconds Freeze Frame. We want it to go to the D: drive, OK and this is going to create a 20 Seconds Freeze Frame, source clip that is going to be saved to my bin here. It looks just like the Motion Effect Editor.
It says FF for Freeze Frame. And if I play it, you can see that there is no motion to it. It's a static image. It's very good for a title or slate. So as you see for basic speed manipulations for source clips, both the Motion Effect Editor and the Freeze Frame Creation tool are really good ways to give yourself options in regard to the speed and look of a clip. If however, you'd like to vary the motion, speed and direction of a shot within the shot itself, you should use the Timewarp effect, which is what we'll cover in the next movie.
