In this article we will teach you how to do the slow motion effect. You will learn how to edit videos with Premiere Pro. We will also tell you about another effect that can help you complement the video to make it look more attractive.
But first, we want to explain some things to keep in mind before even recording the clip. That way, you can work comfortably in post-production and the end result will be optimal.
Things to keep in mind before recording a video to use the slow motion effect in Premiere Pro
If you are recording a video clip to which you will give a slow motion effect, we recommend keeping these aspects in mind to obtain the best results:
- Record the video in 60 FPS or more. That way, you will have more frames per second and the slow motion video will not look choppy.
- Shutter speed must be twice the FPS used. That way, if you’re going to shoot at 60 FPS, you should be working with a shutter speed of 1/125.
- Think carefully about what takes you are going to record for slow motion. It is worth lengthening the clip!
- If you are going to shoot indoors, be careful with the lighting. If you use low-quality light bulbs, the video may flicker or flickering that they produce. Of course with Premiere you can improve low light so that lighting is not a problem.
- When shooting with many frames, noise or grain may increase. Keep this in mind when working in low-light environments.
- By last, do not abuse the effect. If you use it a lot during your video, it will become monotonous and boring.
How to slow down in Premiere Pro
- Drag to the Premiere timeline the portion of video you want to edit.
- Enlarge the box where the video is.
- Select the icon that says “Fx”, located in the upper corner of the video clip. Then click on “Time reassignment” and finally “Speed”.
- With the arrows on the keyboard, control the speed of the video. Please note that 100% is the original speed, so for the slow motion effect you should use values below that figure. On the contrary, to make a fast motion effect, you must use values above 100%.
- Now, right click on the video, then select the option “Speed / Duration” and under “Time interpolation” click on “Optical flow”. Finally, click on “OK”.
After that, process the video. To do this, go to the beginning of it and press the «I» key on your keyboard. Then go to the end and press the «O» key. Now go to the top Premier toolbar. Select option “Sequence” and then “Process input and output”.
In addition, with the help of Premiere you can render the weight of the video faster so that it has quality. Everything will be to improve the work.
The end result will be that a small portion at the beginning and end of the video will be sped up, while the central part of the video will show the slow motion effect. To do this, do the following:
- Go to the Premier tools section (located on the side of the timeline) and select the pen tool.
- Click with the tool on a video section. We recommend that it be shortly after it begins.
- Click on the selection tool and speed up the clip that has been separated from the rest. With Premiere you can reduce the weight of the video without losing quality. You can increase it to 200% -250%, depending on how it looks best.
- Enlarge the video so you can control the time it takes to switch from one effect to another. To do this, just drag the blue or gray arrows that appear above the clip to the left or right.
- Repeat the process for the final part of the clip you are editing.
This effect will serve to complement the slow motion effect. To observe the final result, it would only be necessary to process the video. We hope this article has helped you to put slow motion effect with Premiere Pro.
