Decreasing video footage is something I have the tendency to do regularly when modifying video in Last Cut Pro X. Slow movement video footage can be utilized to provide a remarkable impact, much better emphasize a specific location of a scene, or to merely ravel your video footage.

If you have not done so currently, I advise upgrading to the current variation of Last Cut Pro– variation 10.4. The current variation consists of a range of improvements, consisting of one straight associated to slow movement video efficiency. Make sure to see our complete summary of Last Cut Pro 10.4 in our hands-on walkthrough.
Slow movement essentials
When shooting video footage that you understand you’ll wish to decrease throughout post production, it’s finest to contend the greatest frame rate possible. A greater frame rate provides smoother video footage when decreased than a lower frame rate would. That stated, it’s not constantly possible to predict when you’ll wish to decrease video while shooting.
I have the tendency to shoot the majority of my videos in 24 p (to the irritation of some audiences), so I do not typically get the possibility to routinely deal with high frame rate (60 p or greater) video. If possible, shoot video footage that you’ll wish to decrease in a greater frame rate for a more natural-looking sluggish movement impact. The important things is, I mainly utilize sluggish movement impacts to assist ravel a few of my tripod moves when I remain in a rush.

Ways to decrease video footage on the Last Cut Pro X timeline
One of the most fundamental method to decrease video footage on the Last Cut Pro X timeline is to choose a clip and click the Retiming button. From there you’ll come across a number of alternatives under the Slow area, consisting of 50%, 25% and 10%. The lower the number, the slower your video footage will wind up being.
You can likewise use customized retiming total up to your clips by picking the Custom-made alternative in the Retiming menu. Anything over 100% will lead to an accelerated clip, while anything less than 100% will lead to a clip that’s decreased.
For the sake of this tutorial, we’ll stick to the default sluggish alternatives of 50%, 25% and 10%. When you choose a worth, you’ll see that the picked clip ends up being longer on the timeline, since it’s length is increased as the video footage is decreased. The inverse holds true of accelerated video footage.
When you repeat a sluggish movement clip, you might see that playback is choppy after rendering. Much will depend upon the frame rate of the video utilized on the timeline. If the task is set at 30 p and the video footage that you decrease is 60 p video footage, then it will lead to smoother playback when decreased than if the video footage was 30 p. The greater the frame rate of the initial video footage, the smoother your sluggish movement will be utilizing the retiming tools in Last Cut Pro X.
Utilizing video quality alternatives to enhance sluggish movement
Although the iPhone can shoot sluggish movement at a remarkable 240 FPS completely HD, not everybody wishes to utilize a cell phone for their videos, or has access to a standalone video camera that can contend such high frame rates. And exactly what if you wish to include sluggish movement to a 4K task? A lot of budget-friendly standalone cams on the marketplace, other than for the Panasonic GH5, are restricted when it concerns 4K frame rate.
Luckily, there are a few methods to smooth decreased video footage utilizing Last Cut Pro X’s helpful integrated video quality tools. The very first approach is called Frame Mixing, and you can discover it under the Retiming → Video Quality area of Last Cut Pro X.
Frame Mixing produces brand-new between frames, each a composite of 2 surrounding frames, in order to decrease the stutter connected with the replicate frames had to decrease video footage. It’s essentially utilizing a mixing impact to extend the video footage in a manner that can appear more natural and less tense. With this in mind, I discover that Frame Mixing is more apt for small sluggish movement impacts, i.e. 50% or greater. When you begin extending beyond that, Frame Mixing can begin to break down.
The 2nd approach is called Optical Circulation Inning accordance with Apple:
Optical Circulation Includes between frames utilizing an optical circulation algorithm, which evaluates the clip to figure out the directional motion of pixels and after that draws parts of the brand-new frames based upon the optical circulation analysis
Significantly, Optical Circulation was upgraded in Last Cut Pro 10.4 to make the most of Metal 2. Both Optical Circulation and Frame Mixing need making.
I discover that for more extreme sluggish movement efforts, Optical Circulation is the much better impact to utilize. Remember, however, that for specific kinds of motions, neither alternatives are replacements for a high frame rate source video footage. Normally speaking, the much faster the motion of products in frame, the harder it is to use frame interpolation impacts to the video footage.
Simply puts, both Frame Mixing and Optical Circulation can wind up making your video footage appearance wonky if not used to a perfect situation. I discover that these video impacts work best with easy tripod relocations (sluggish pans, tilts, and pedestals). When you have a great deal of quick motion of the topics in frame, then issues can begin to develop.
To conclude, it’s finest if you can shoot video at a high frame rate if you understand that you’ll wish to decrease that video footage in post, specifically if it includes quick moving topics throughout various focal airplanes. That stated, even if you do not contend greater frame rates does not always render your sluggish movement efforts null and space. Last Cut Pro X has a number of tools that make it possible to manage persuading sluggish movement depending upon the video footage and aspects included.
This is simply the start of a series of guide prepared to talk about sluggish movement pointers and techniques in Last Cut Pro X. Stay tuned for more information in future posts. In the meantime, please make certain to share a few of your pointers and observations down below in the remarks area.
