By default, the Linear from Start/End buttons are selected which produce no speed ramps. You can also think of them as speed ramping buttons. There are two rows of buttons labeled Start and End that are used for controlling the rate of the speed change at the beginning and end of your clip. With the first clip still selected, press Command-J on your keyboard to bring up the Change Speed dialogue. To make your speed changes more ballistically accurate, you'll want to add some ease in and ease out controls. In the real world, objects moving through space observe laws of physics and change velocity over time. More on that in a bit.Īfter playing back the speed-adjusted clip, you'll notice the clip starts and ends abruptly. Variable speed changes on the other hand, only affect the video portion of the clip. The amount of pitch change is proportional to the speed percentage you entered in the Change Speed dialogue. This means that your audio will always play back with a pitch change. What is also important to understand is that constant speed changes affect both the video and the audio. The speed ticks are applied uniformly which indicates a constant or "fixed" speed for the clip's entire duration. Speed ticks that are further apart indicate a speed reduction, and speed ticks that are closer together indicate a speed increase. If you look at the speed ticks in the timeline, they appear further apart. If you want to prevent the other clips from moving, uncheck the box labeled "Ripple Sequence" and the clip's original duration will be maintained. If we were to take no further action and apply the speed change by pressing Return, the 2 clips to the right in the timeline, would move or "ripple" 1 second later in time. In this example, the difference between the new duration and original duration is roughly 1 second. The original clip duration of 5 seconds and 26 frames is reported for comparison.īecause constant speed changes alter the duration of your clip, any clip in the timeline to the immediate right of the clip you are speed-adjusting will be moved later (or earlier) in time by the amount equal to the difference between the original duration and the new duration. The speed percentage is auto-adjusted to 83 percent.
Enter 7 seconds in the duration field and press the Tab key. You can also change the speed by entering a duration. In this example, the duration value is doubled because we are slowing down the clip by 50 percent.

Press your Tab key instead, and the duration field will update with the clip's new duration based on your entered speed. Now here's a gotcha do not press Return unless you want this speed change immediately applied to your clip. You can also bring this window up by selecting a clip (or multiple clips) and pressing Command-J on your keyboard. To apply a constant speed change to a clip, right-click on the first clip and choose Change Speed from the menu.įinal Cut Pro's Change Speed dialogue appears. There are two types of speed changes you can apply - constant speed changes, that affect the clip's speed by a fixed percentage over time, and variable speed changes that affect the clip's speed by altering the speed percentage over time. The clip keyframe graph is displayed along with speed tick marks. In order to see how your speed changes are being applied to the clips, click the Toggle Clip Keyframes button in the lower left of the timeline. You'll need to have Final Cut Pro 7.01 or later installed in order to follow along. (89 Megs)Īfter downloading, launch the project and make sure the SpeedFreaks sequence is open.

Feel free to follow along using your own footage, just keep in mind that the results you obtain may not match my examples do to the fact that your media will have differing timecodes, durations and in some cases, differing frame rates.ĭownload the project and project files. To make this article more interactive, I'm including a link to the project and media I refer to in this article so you can follow along in your own copy of Final Cut Pro 7. In this article, my intention is to walk you through these new speed tools using a short 3 clip sequence from the MavTV show "SpeedFreaks". With the release of Final Cut Pro 7, it seems clear that Apple has listened to its user base and in my opinion, the new Speed Tools present one of the strongest arguments for upgrading to the latest release of Final Cut Studio. Altering speed is therefore a staple in editorial aesthetics and new tools to this end must keep the process simple, straight-forward and efficient.
Since the early days of cinema, filmmakers have manipulated time for dramatic or comedic effect.
